Overdosage of TEKTURNA
Information about signs, symptoms, and laboratory findings of acute ovedosage and the general principles of overdose treatment.10 OVERDOSAGE Limited data are available related to overdosage in humans. The most likely manifestation of overdosage would be hypotension. If symptomatic hypotension occurs, supportive treatment should be initiated. Aliskiren is poorly dialyzed. Therefore, hemodialysis is not adequate to treat aliskiren overexposure [see Clinical Pharmacology ( 12.3 )] .
Adverse reactions
Information about undesirable effects, reasonably associated with use of the drug, that may occur as part of the pharmacological action of the drug or may be unpredictable in its occurrence. Adverse reactions include those that occur with the drug, and if applicable, with drugs in the same pharmacologically active and chemically related class. There is considerable variation in the listing of adverse reactions. They may be categorized by organ system, by severity of reaction, by frequency, by toxicological mechanism, or by a combination of these.6 ADVERSE REACTIONS Most common adverse reaction: diarrhea (incidence 2.3%) ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact LXO US Inc. at 1-844-800-8007 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. Most common adverse reaction: diarrhea (incidence 2.3%) ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact LXO US Inc. at 1-844-800-8007 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience The following serious adverse reactions are discussed in greater detail in other sections of the label: Fetal Toxicity [see Warnings and Precautions ( 5.1 )] Anaphylactic Reactions and Head and Neck Angioedema [see Warnings and Precautions ( 5.3 )] Hypotension [see Warnings and Precautions ( 5.4 )] Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in clinical trials of another drug and may not reflect the rates observed in practice. Adult Hypertension Data described below reflect the evaluation of the safety of Tekturna in more than 6,460 patients, including over 1,740 treated for longer than 6 months, and more than 1,250 patients for longer than 1 year. In placebo-controlled clinical trials, discontinuation of therapy due to a clinical adverse event, including uncontrolled hypertension, occurred in 2.2% of patients treated with Tekturna versus 3.5% of patients given placebo. These data do not include information from the ALTITUDE study which evaluated the use of aliskiren in combination with ARBs or ACEIs [see Contraindications ( 4 ), Warnings and Precautions ( 5.2 ), and Clinical Studies ( 14.3 )]. Angioedema: Two cases of angioedema with respiratory symptoms were reported with Tekturna use in the clinical studies. Two other cases of periorbital edema without respiratory symptoms were reported as possible angioedema and resulted in discontinuation. The rate of these angioedema cases in the completed studies was 0.06%. In addition, 26 other cases of edema involving the face, hands, or whole body were reported with Tekturna use including 4 leading to discontinuation. In the placebo-controlled studies, however, the incidence of edema involving the face, hands, or whole body was 0.4% with Tekturna compared with 0.5% with placebo. In a long-term active-control study with Tekturna and hydrochlorothiazide (HCTZ) arms, the incidence of edema involving the face, hand or whole body was 0.4% in both treatment arms [see Warnings and Precautions ( 5.2 )]. Gastrointestinal: Tekturna produces dose-related gastrointestinal (GI) adverse reactions. Diarrhea was reported by 2.3% of patients at 300 mg, compared to 1.2% in placebo patients. In women and the elderly (age 65 years and older) increases in diarrhea rates were evident starting at a dose of 150 mg daily, with rates for these subgroups at 150 mg comparable to those seen at 300 mg for men or younger patients (all rates about 2.0% to 2.3%). Other GI symptoms included abdominal pain, dyspepsia, and gastroesophageal reflux, although increased rates for abdominal pain and dyspepsia were distinguished from placebo only at 600 mg daily. Diarrhea and other GI symptoms were typically mild and rarely led to discontinuation. Cough: Tekturna was associated with a slight increase in cough in the placebo-controlled studies (1.1% for any Tekturna use versus 0.6% for placebo). In active-controlled trials with ACE inhibitor (ramipril, lisinopril) arms, the rates of cough for the Tekturna arms were about one-third to one-half the rates in the ACE inhibitor arms. Seizures: Single episodes of tonic-clonic seizures with loss of consciousness were reported in 2 patients treated with Tekturna in the clinical trials. One of these patients did have predisposing causes for seizures and had a negative electroencephalogram (EEG) and cerebral imaging following the seizures (for the other patient EEG and imaging results were not reported). Tekturna was discontinued and there was no rechallenge. Other adverse effects with increased rates for Tekturna compared to placebo included rash (1% versus 0.3%), elevated uric acid (0.4% versus 0.1%), gout (0.2% versus 0.1%) and renal stones (0.2% versus 0%). Aliskiren's effect on ECG intervals was studied in a randomized, double-blind, placebo and active-controlled (moxifloxacin), 7-day repeat dosing study with Holter-monitoring and 12 lead ECGs throughout the interdosing interval. No effect of aliskiren on QT interval was seen. Pediatric Hypertension Aliskiren has been evaluated for safety in 267 pediatric hypertensive patients 6 to 17 years of age; including 208 patients treated for 52 weeks [see Clinical Studies ( 14.4 )] . These studies did not reveal any unanticipated adverse reactions. Adverse reactions in pediatric patients 6 years of age and older are expected to be similar to those seen in adults. Clinical Laboratory Findings In controlled clinical trials, clinically relevant changes in standard laboratory parameters were rarely associated with the administration of Tekturna in patients with hypertension not concomitantly treated with an ARB or ACEI. In multiple- dose studies in hypertensive patients, Tekturna had no clinically important effects on total cholesterol, HDL, fasting triglycerides, or fasting glucose. Blood Urea Nitrogen, Creatinine : In patients with hypertension not concomitantly treated with an ARB or ACEI, minor increases in blood urea nitrogen (BUN) or serum creatinine were observed in less than 7% of patients treated with Tekturna alone versus 6% on placebo [see Warnings and Precautions ( 5.2 )] . Hemoglobin and Hematocrit : Small decreases in hemoglobin and hematocrit (mean decreases of approximately 0.08 g/dL and 0.16 volume percent, respectively, for all aliskiren monotherapy) were observed. The decreases were dose-related and were 0.24 g/dL and 0.79 volume percent for 600 mg daily. This effect is also seen with other agents acting on the renin angiotensin system, such as angiotensin inhibitors and ARBs, and may be mediated by reduction of angiotensin II which stimulates erythropoietin production via the AT1 receptor. These decreases led to slight increases in rates of anemia with aliskiren compared to placebo were observed (0.1% for any aliskiren use, 0.3% for aliskiren 600 mg daily, versus 0% for placebo). No patients discontinued therapy due to anemia. Serum Potassium : In patients with hypertension not concomitantly treated with an ARB or ACEI, increases in serum potassium greater than 5.5 mEq/L were infrequent (0.9% compared to 0.6% with placebo) [see Contraindications ( 4 ) and Warnings and Precautions ( 5.6 )] . Serum Uric Acid : Aliskiren monotherapy produced small median increases in serum uric acid levels (about 6 micromol/L) while HCTZ produced larger increases (about 30 micromol/L). The combination of aliskiren with HCTZ appears to be additive (about 40 micromol/L increase). The increases in uric acid appear to lead to slight increases in uric acid-related AEs: elevated uric acid (0.4% versus 0.1%), gout (0.2% versus. 0.1%), and renal stones (0.2% versus 0%). Creatine Kinase : Increases in creatine kinase of greater than 300% were recorded in about 1% of aliskiren monotherapy patients versus 0.5% of placebo patients. Five cases of creatine kinase rises, 3 leading to discontinuation and 1 diagnosed as subclinical rhabdomyolysis, and another as myositis, were reported as adverse events with aliskiren use in the clinical trials. No cases were associated with renal dysfunction. 6.2 Postmarketing Experience The following adverse reactions have been reported in aliskiren postmarketing experience. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to estimate their frequency or establish a causal relationship to drug exposure. Hypersensitivity: anaphylactic reactions and angioedema requiring airway management and hospitalization Urticaria Peripheral edema Hepatic enzyme increase with clinical symptoms of hepatic dysfunction Severe cutaneous adverse reactions, including Stevens-Johnson syndrome and toxic epidermal necrolysis Pruritus Erythema Hyponatremia Nausea, Vomiting
TEKTURNA Drug Interactions
Information about and practical guidance on preventing clinically significant drug/drug and drug/food interactions that may occur in people taking the drug.7 DRUG INTERACTIONS Cyclosporine: Avoid coadministration of cyclosporine with aliskiren [see Warnings and Precautions ( 5.7 ) and Clinical Pharmacology ( 12.3 )] . Itraconazole: Avoid coadministration of itraconazole with aliskiren [see Warnings and Precautions ( 5.7 ) and Clinical Pharmacology ( 12.3 )]. Nonsteroidal Anti-Inflammatory Drugs (NSAIDs) including selective Cyclooxygenase-2 inhibitors (COX-2 inhibitors): In patients who are elderly, volume-depleted (including those on diuretic therapy), or with compromised renal function, coadministration of NSAIDs, including selective COX-2 inhibitors with agents that affect the RAAS, including aliskiren, may result in deterioration of renal function, including possible acute renal failure. These effects are usually reversible. Monitor renal function periodically in patients receiving aliskiren and NSAID therapy. The antihypertensive effect of aliskiren may be attenuated by NSAIDs. Dual Blockade of the Renin-Angiotensin-Aldosterone System (RAAS): The concomitant use of aliskiren with other agents acting on the RAAS such as ACEIs or ARBs is associated with an increased risk of hypotension, hyperkalemia, and changes in renal function (including acute renal failure) compared to monotherapy. Most patients receiving the combination of two drugs that inhibit the renin-angiotensin system do not obtain any additional benefit compared to monotherapy. In general, avoid combined use of aliskiren with ACE inhibitors or ARBs, particularly in patients with CrCl less than 60 mL/min. Monitor blood pressure, renal function, and electrolytes in patients taking aliskiren and other agents that affect the RAAS [see Warnings and Precautions ( 5.4 , 5.5 , 5.6 )]. The concomitant use of aliskiren with an ARB or an ACEI in diabetic patients is contraindicated [see Contraindications ( 4 )]. Furosemide: Oral coadministration of aliskiren and furosemide reduced exposure to furosemide. Monitor diuretic effects when furosemide is coadministered with aliskiren. Cyclosporine or Itraconazole: Avoid concomitant use. ( 5.7 , 7 , 12.3 ) Nonsteroidal Anti-Inflammatory Drugs (NSAIDs): Increased risk of renal impairment and loss of antihypertensive effect. ( 7 )
Clinical pharmacology
Information about the clinical pharmacology and actions of the drug in humans.12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Renin is secreted by the kidney in response to decreases in blood volume and renal perfusion. Renin cleaves angiotensinogen to form the inactive decapeptide angiotensin I (Ang I). Ang I is converted to the active octapeptide angiotensin II (Ang II) by ACE and non-ACE pathways. Ang II is a powerful vasoconstrictor and leads to the release of catecholamines from the adrenal medulla and prejunctional nerve endings. It also promotes aldosterone secretion and sodium reabsorption. Together, these effects increase blood pressure. Ang II also inhibits renin release, thus providing a negative feedback to the system. This cycle, from renin through angiotensin to aldosterone and its associated negative feedback loop, is known as the renin-angiotensin-aldosterone system (RAAS). Aliskiren is a direct renin inhibitor, decreasing plasma renin activity (PRA) and inhibiting the conversion of angiotensinogen to Ang I. Whether aliskiren affects other RAAS components, e.g., ACE or non-ACE pathways, is not known. All agents that inhibit the RAAS, including renin inhibitors, suppress the negative feedback loop, leading to a compensatory rise in plasma renin concentration. When this rise occurs during treatment with ACEIs and ARBs, the result is increased levels of PRA. During treatment with aliskiren, however, the effect of increased renin levels is blocked so that PRA, Ang I and Ang II are all reduced, whether aliskiren is used as monotherapy or in combination with other antihypertensive agents. 12.2 Pharmacodynamics In placebo-controlled clinical trials, PRA was decreased in a range of 50% to 80%. This reduction in PRA was not dose- related and did not correlate with blood pressure reductions. The clinical implications of the differences in effect on PRA are not known. 12.3 Pharmacokinetics Aliskiren is poorly absorbed (bioavailability about 2.5%) with an approximate accumulation half-life of 24 hours. Steady state blood levels are reached in about 7 to 8 days. Absorption and Distribution Following oral administration, peak plasma concentrations of aliskiren are reached within 1 to 3 hours. When taken with a high-fat meal, mean AUC and C max of aliskiren are decreased by 71% and 85% respectively. In the clinical trials of aliskiren, it was administered without requiring a fixed relation of administration to meals. Metabolism and Elimination About one-fourth of the absorbed dose appears in the urine as parent drug. How much of the absorbed dose is metabolized is unknown. Based on the in vitro studies, the major enzyme responsible for aliskiren metabolism appears to be CYP3A4. Aliskiren does not inhibit the CYP450 isoenzymes (CYP 1A2, 2C8, 2C9, 2C19, 2D6, 2E1, and 3A) or induce CYP3A4. Transporters: Pgp (MDR1/Mdr1a/1b) was found to be the major efflux system involved in intestinal absorption and elimination via biliary excretion of aliskiren in preclinical studies. The potential for drug interactions at the Pgp site will likely depend on the degree of inhibition of this transporter. Drug Interactions The effect of coadministered drugs on the pharmacokinetics of aliskiren and vice versa, were studied in several single- and multiple-dose studies. Pharmacokinetic measures indicating the magnitude of these interactions are presented in Figure 1 (impact of coadministered drugs on aliskiren) and Figure 2 (impact of aliskiren on coadministered drugs). Figure 1: The Impact of Coadministered Drugs on the Pharmacokinetics of Aliskiren *Ketoconazole: A 400 mg once daily dose was not studied, but would be expected to increase aliskiren blood levels further. **Ramipril, valsartan, irbesartan: In general, avoid combined use of aliskiren with ACE inhibitors or ARBs, particularly in patients with CrCl less than 60 mL/min [see Drug Interactions ( 7 )]. Warfarin: There was no clinically significant effect of a single dose of warfarin 25 mg on the pharmacokinetics of aliskiren. Figure 2: The Impact of Aliskiren on the Pharmacokinetics of Coadministered Drugs *Furosemide: Patients receiving furosemide could find its effects diminished after starting aliskiren. In patients with heart failure, coadministration of aliskiren (300 mg/day) reduced plasma AUC and C max of oral furosemide (60 mg/day) by 17% and 27%, respectively, and reduced 24-hour urinary furosemide excretion by 29%. This change in exposure did not result in statistically significant difference in total urine volume and urinary sodium excretion over 24 hours. However, a transient decrease in urinary sodium excretion and urine volume effects up to 12 hours were observed when furosemide was coadministered with aliskiren 300 mg/day. **Ramipril, valsartan: In general, avoid combined use of aliskiren with ACE inhibitors or ARBs, particularly in patients with CrCl less than 60 mL/min [see Drug Interactions ( 7 )]. Figure 1 Figure 2 Specific Populations Renally Impaired Patients: Aliskiren was evaluated in adult patients with varying degrees of renal insufficiency. The rate and extent of exposure (AUC and C max ) of aliskiren in subjects with renal impairment did not show a consistent correlation with the severity of renal impairment. Adjustment of the starting dose is not required in these patients [see Warnings and Precautions ( 5.2 )] . The pharmacokinetics of aliskiren following administration of a single oral dose of 300 mg was evaluated in adult patients with End Stage Renal Disease (ESRD) undergoing hemodialysis. When compared to matched healthy subjects, changes in the rate and extent of aliskiren exposure (C max and AUC) in ESRD patients undergoing hemodialysis were not clinically significant. Timing of hemodialysis did not significantly alter the pharmacokinetics of aliskiren in ESRD patients. Therefore, no dose adjustment is warranted in ESRD patients receiving hemodialysis. Hepatically Impaired Patients: The pharmacokinetics of aliskiren were not significantly affected in patients with mild to severe liver disease. Consequently, adjustment of the starting dose is not required in these patients. Pediatric Patients: The pharmacokinetics of aliskiren were evaluated in an 8-day pharmacokinetic study in 39 pediatric patients with hypertension 6 years to 17 years of age. Aliskiren was given as daily doses of 2 mg/kg (0.67 times the lowest approved recommended dosage in a 50 kg pediatric patient) or 6 mg/kg (the highest recommended approved dosage in a 50 kg pediatric patient), administered as mini-tablets (3.125 mg oral pellets). The pharmacokinetic parameters of aliskiren were similar to those in adults, and the results of this study do not suggest that age or gender have any significant effect on aliskiren systemic exposure in patients 6 years to 17 years of age. Exposure decreased with increase in body weight. In an 8-week randomized double blind study with aliskiren monotherapy in 267 pediatric patients with hypertension 6 years to 17 years of age [see Clinical Studies ( 14.4 )] , fasting trough aliskiren concentrations at Day 28 demonstrated similar drug trough exposure levels to those observed in other trials using similar aliskiren doses in both adults and pediatric patients. Geriatric Patients: Exposure (measured by AUC) is increased in elderly patients 65 years and older. Adjustment of the starting dose is not required in these patients. Racial or Ethnic Groups : The pharmacokinetic differences between blacks, Caucasians, and Japanese are minimal.

Contraindications
Information about situations in which the drug product is contraindicated or should not be used because the risk of use clearly outweighs any possible benefit, including the type and nature of reactions that have been reported.4 CONTRAINDICATIONS Do not use Tekturna with ARBs or ACEIs in patients with diabetes [see Warnings and Precautions ( 5.2 ) and Clinical Studies ( 14.3 )]. Tekturna is contraindicated in patients with known hypersensitivity to any of the components [see Warnings and Precautions ( 5.3 )]. Tekturna is contraindicated in pediatric patients less than 2 years of age because of the risk of high aliskiren exposures identified in juvenile animals due to immaturity of transporters and metabolic enzymes [see Use in Specific Populations ( 8.4 )]. Do not use with angiotensin receptor blockers (ARBs) or angiotensin- converting enzyme inhibitors (ACEIs) in patients with diabetes. ( 4 ) Hypersensitivity to any of the components. ( 4 ) Tekturna is contraindicated in pediatric patients less than 2 years of age. ( 4 )

Dosage and administration
Information about the drug product’s dosage and administration recommendations, including starting dose, dose range, titration regimens, and any other clinically sigificant information that affects dosing recommendations.2 DOSAGE AND ADMINISTRATION Starting dose (adults and pediatric patients): 150 mg once daily with a routine pattern with regard to meals. If blood pressure remains uncontrolled titrate up to 300 mg daily. ( 2.1 ) Majority of effect of given dose attained in 2 weeks. ( 2.1 ) 2.1 Recommended Dosage In adult patients and in pediatric patients weighing 50 kg or greater who are at least 6 years of age, the recommended starting dose of Tekturna is 150 mg once daily. In patients whose blood pressure is not adequately controlled, the daily dose may be increased to 300 mg once daily. Doses above 300 mg did not give an increased blood pressure response but resulted in an increased rate of diarrhea. The antihypertensive effect of a given dosage is substantially attained (85% to 90%) by 2 weeks. 2.2 Relationship to Meals Patients should establish a routine pattern for taking Tekturna with regard to meals. High-fat meals decrease absorption substantially [see Clinical Pharmacology ( 12.3 )].

Indications and usage
A statement of each of the drug products indications for use, such as for the treatment, prevention, mitigation, cure, or diagnosis of a disease or condition, or of a manifestation of a recognized disease or condition, or for the relief of symptoms associated with a recognized disease or condition. This field may also describe any relevant limitations of use.1 INDICATIONS AND USAGE Tekturna is a renin inhibitor (RI) indicated for the treatment of hypertension in adults and in pediatric patients weighing 50 kg or greater who are at least 6 years of age, to lower blood pressure. Lowering blood pressure reduces the risk of fatal and nonfatal cardiovascular events, primarily strokes and myocardial infarctions. ( 1.1 ) 1.1 Hypertension Tekturna is indicated for the treatment of hypertension in adults and in pediatric patients weighing 50 kg or greater who are at least 6 years of age and older to lower blood pressure. Lowering blood pressure reduces the risk of fatal and nonfatal cardiovascular events, primarily strokes and myocardial infarctions. These benefits have been seen in controlled trials of antihypertensive drugs from a wide variety of pharmacologic classes. There are no controlled trials demonstrating risk reduction with Tekturna. Control of high blood pressure should be part of comprehensive cardiovascular risk management, including, as appropriate, lipid control, diabetes management, antithrombotic therapy, smoking cessation, exercise, and limited sodium intake. Many patients will require more than 1 drug to achieve blood pressure goals. For specific advice on goals and management, see published guidelines, such as those of the National High Blood Pressure Education Program's Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC). Numerous antihypertensive drugs, from a variety of pharmacologic classes and with different mechanisms of action, have been shown in randomized controlled trials to reduce cardiovascular morbidity and mortality, and it can be concluded that it is blood pressure reduction, and not some other pharmacologic property of the drugs, that is largely responsible for those benefits. The largest and most consistent cardiovascular outcome benefit has been a reduction in the risk of stroke, but reductions in myocardial infarction and cardiovascular mortality have also been seen regularly. Elevated systolic or diastolic pressure causes increased cardiovascular risk, and the absolute risk increase per mmHg is greater at higher blood pressures, so that even modest reductions of severe hypertension can provide substantial benefit. Relative risk reduction from blood pressure reduction is similar across populations with varying absolute risk, so the absolute benefit is greater in patients who are at higher risk independent of their hypertension (e.g., patients with diabetes or hyperlipidemia), and such patients would be expected to benefit from more aggressive treatment to a lower blood pressure goal. Some antihypertensive drugs have smaller blood pressure effects (as monotherapy) in black patients, and many antihypertensive drugs have additional approved indications and effects (e.g., on angina, heart failure, or diabetic kidney disease). These considerations may guide selection of therapy.

Information about carcinogenic, mutagenic, or fertility impairment potential revealed by studies in animals. Information from human data about such potential is part of the warnings field.13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility Carcinogenic potential was assessed in a 2-year rat study and a 6-month transgenic (rasH2) mouse study with aliskiren hemifumarate at oral doses of up to 1500 mg aliskiren/kg/day. Although there were no statistically significant increases in tumor incidence associated with exposure to aliskiren, mucosal epithelial hyperplasia (with or without erosion/ulceration) was observed in the lower gastrointestinal tract at doses of greater than or equal to 750 mg/kg/day in both species, with a colonic adenoma identified in 1 rat and a cecal adenocarcinoma identified in another, rare tumors in the strain of rat studied. On a systemic exposure (AUC 0-24hr ) basis, 1500 mg/kg/day in the rat is about 4 times and in the mouse about 1.5 times the maximum recommended human dose (MRHD) (300 mg aliskiren/day). Mucosal hyperplasia in the cecum or colon of rats was also observed at doses of 250 mg/kg/day (the lowest tested dose) as well as at higher doses in 4- and 13- week studies. Aliskiren hemifumarate was devoid of genotoxic potential in the Ames reverse mutation assay with S. typhimurium and E. coli , the in vitro Chinese hamster ovary cell chromosomal aberration assay, the in vitro Chinese hamster V79 cell gene mutation test and the in vivo mouse bone marrow micronucleus assay. Fertility of male and female rats was unaffected at doses of up to 250 mg aliskiren/kg/day (8 times the MRHD of 300 mg Tekturna/60 kg on a mg/m 2 basis.)

Clinical studies
This field may contain references to clinical studies in place of detailed discussion in other sections of the labeling.14 CLINICAL STUDIES 14.1 Aliskiren Monotherapy The antihypertensive effects of Tekturna have been demonstrated in 6 randomized, double-blind, placebo-controlled 8- week clinical trials in patients with mild-to-moderate hypertension. The placebo response and placebo-subtracted changes from baseline in seated trough cuff blood pressure are shown in Table 2 . Table 2: Reductions in Seated Trough Cuff Blood Pressure (mmHg systolic/diastolic) in the Placebo-Controlled Studies *p value less than 0.05 versus placebo by ANCOVA with Dunnett's procedure for multiple comparisons †p value less than 0.05 versus placebo by ANCOVA for the pairwise comparison.

The recommended dosage of Tekturna is either 150 or 300 mg once daily [see Dosage and Administration ( 2.1 )]. As shown in Table 1, there is some increase in response with administered dose in all studies, with reasonable effects seen at 150mg to 300 mg, and no clear further increases at 600 mg. A substantial proportion (85% to 90%) of the blood pressure-lowering effect was observed within 2 weeks of treatment. Studies with ambulatory blood pressure monitoring showed reasonable control throughout the interdosing interval; the ratios of mean daytime to mean nighttime ambulatory BP range from 0.6 to 0.9. Patients in the placebo-controlled trials continued open-label aliskiren for up to 1 year. A persistent blood pressure- lowering effect was demonstrated by a randomized withdrawal study (patients randomized to continue drug or placebo), which showed a statistically significant difference between patients kept on aliskiren and those randomized to placebo. With cessation of treatment, blood pressure gradually returned toward baseline levels over a period of several weeks. There was no evidence of rebound hypertension after abrupt cessation of therapy. Aliskiren lowered blood pressure in all demographic subgroups, although black patients tended to have smaller reduction than Caucasians and Asians, as has been seen with ACEIs and ARBs. There are no studies of Tekturna or members of the direct renin inhibitors demonstrating reductions in cardiovascular risk in patients with hypertension. 14.2 Aliskiren in Combination with Other Antihypertensives Hydrochlorothiazide (HCTZ) Aliskiren 75, 150, and 300 mg (0.5 times the recommended lowest dosage, the lowest recommended dosage, and the maximum recommended dosage, respectively) and HCTZ 6.25, 12.5, and 25 mg were studied alone and in combination in an 8-week, 2,776-patient, randomized, double-blind, placebo-controlled, parallel-group, 15-arm factorial study. Blood pressure reductions with the combinations were greater than the reductions with the monotherapies as shown in Table 3 .

The dosages of aliskiren and valsartan were started at 150 mg and 160 mg, respectively, and increased at 4 weeks to 300 mg and 320 mg, respectively. Seated trough cuff blood pressure was measured at baseline, 4, and 8 weeks. Blood pressure reductions with the combinations were greater than the reductions with the monotherapies as shown in Table 4 . In general, the combination of aliskiren and angiotensin receptor blocker should be avoided [see Contraindications ( 4 ), Warnings and Precautions ( 5 ), and Drug Interactions ( 7 )]. Table 4: Placebo-Subtracted Reductions in Seated Trough Cuff Blood Pressure (mmHg systolic/diastolic) in Combination with Valsartan * The placebo change is 5.2/4.8 for week 4 endpoint which was used for the dose groups containing aliskiren 150 mg or valsartan 160 mg.

Treatment with aliskiren and amlodipine resulted overall in significantly greater reductions in diastolic and systolic blood pressure compared to the respective monotherapy components as shown in Table 5 .

All patients were receiving background therapy with an ARB or ACEI. The primary efficacy outcome was the time to the first event of the primary composite endpoint consisting of cardiovascular death, resuscitated sudden death, nonfatal myocardial infarction, nonfatal stroke, unplanned hospitalization for heart failure, onset of end stage renal disease, renal death, and doubling of serum creatinine concentration from baseline sustained for at least 1 month. After a median follow-up of about 32 months, the trial was terminated early for lack of efficacy. Higher risk of renal impairment, hypotension and hyperkalemia was observed in aliskiren compared to placebo-treated patients, as shown in Table 6 . Table 6: Incidence of Selected Adverse Events During the Treatment Phase in ALTITUDE † renal failure, renal failure acute, renal failure chronic, renal impairment †† dizziness, dizziness postural, hypotension, orthostatic hypotension, presyncope, syncope ††† Given the variable baseline potassium levels of patients with renal insufficiency on dual RAAS therapy, the reporting of adverse event of hyperkalemia was at the discretion of the investigator. * A Serious Adverse Event (SAE) is defined as: an event which is fatal or life-threatening, results in persistent or significant disability/incapacity, constitutes a congenital anomaly/birth defect, requires inpatient hospitalization or prolongation of existing hospitalization, or is medically significant (i.e., defined as an event that jeopardizes the patient or may require medical or surgical intervention to prevent one of the outcomes previously listed).

The majority of patients (82%) had primary hypertension, 59% had a BMI ≥95 th percentile, 20% had an estimated GFR between 60 and 90 mL/min/1.73m 2 and < 2% had an estimated GFR < 60 mL/min/1.73m 2 . The mean age was 11.8 years and 74% of patients were Caucasian. In the initial 4-week,dose-response phase of the trial patients were randomized to weight-based low, mid and high dosing groups. At the end of this phase, patients entered a 4-week randomized withdrawal phase in which they were re-randomized in each weight category in a 1:1 ratio to continue the same dose of aliskiren or take placebo. During the initial dose-response phase, aliskiren reduced both systolic and diastolic blood pressure in a weight-based dose-dependent manner. Sitting systolic blood pressure, the trial's primary endpoint, was reduced by 4.8, 5.6 and 8.7 mmHg from baseline in the low, medium and high dose groups, respectively. In the randomized withdrawal phase, the mean difference between the high dose group of aliskiren and placebo in the mean change in sitting systolic blood pressure was -2.7 mmHg. Following the 8-week trial, 208 patients were enrolled in a 52-week extension trial in which patients were randomized in a 1:1 ratio (irrespective of whether they were on placebo or aliskiren at the end of the 8-week study) to receive either aliskiren or enalapril (CSPP100A2365E1; NCT01151410). The extension study included 3 dose levels based on weight; optional dose up-titrations were allowed during the study to control blood pressure. At the end of 52 weeks, reductions in blood pressure from baseline were similar in patients receiving aliskiren (7.6/3.9 mmHg) and enalapril (7.9/4.9 mmHg).

Geriatric use
Information about any limitations on any geriatric indications, needs for specific monitoring, hazards associated with use of the drug in the geriatric population.8.5 Geriatric Use Of the total number of patients receiving aliskiren in clinical studies, 1,275 (19%) were 65 years or older and 231 (3.4%) were 75 years or older. No overall differences in safety or effectiveness were observed between these subjects and younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out.
Pediatric use
Information about any limitations on any pediatric indications, needs for specific monitoring, hazards associated with use of the drug in any subsets of the pediatric population (such as neonates, infants, children, or adolescents), differences between pediatric and adult responses to the drug, and other information related to the safe and effective pediatric use of the drug.8.4 Pediatric Use Tekturna is contraindicated in patients less than 2 years of age [see Contraindications ( 4 )]. Tekturna is indicated for treatment of hypertension in pediatric patients 6 years of age and older weighing 50 kg or more. The safety and effectiveness of aliskiren have been established in pediatric patients 6 years of age and older weighing 20 kg or more, but Tekturna is not approved in patients 6 years of age and older weighing 20 kg to less than 50 kg because of the lack of an appropriate dosage form. Use of Tekturna in pediatric patients 6 years and older is supported by evidence from a pharmacokinetic trial and two randomized, double-blind clinical trials in pediatric patients with hypertension 6 years to 17 years of age weighing 20 kg or more [see Clinical Pharmacology ( 12.3 ), Clinical Studies ( 14.4 ) ] . The safety and effectiveness of Tekturna have not been established in pediatric patients younger than 6 years of age and patients less than 20 kg. Avoid use in patients 2 years to less than 6 years and patients weighing less than 20 kg due to the limited information about aliskiren metabolism and exposures in this age group. No data are available in pediatric patients weighing less than 20 kg or in pediatric patients with a glomerular filtration rate <30 mL/min/1.73 m 2 . Juvenile Animal Toxicity Data Toxicology studies in juvenile animals the approximate human age equivalent of children less than 2 years of age identified 85- to 385-fold increased systemic exposure to aliskiren compared to adult rats. The increased aliskiren exposure in juvenile rats was attributed to immaturity in aliskiren drug transporters and metabolizing enzymes. Increased aliskiren exposures were associated with premature deaths. Although a definitive pathology-based cause of death could not be ascertained, the premature deaths were attributed to the immaturity in aliskiren metabolism. The nonclinical findings suggest a distinct age-dependent relationship between dose and exposure. Neonates with a history of in utero exposure to Tekturna If oliguria or hypotension occurs, direct attention toward support of blood pressure and renal perfusion. Exchange transfusions or dialysis may be required as a means of reversing hypotension and/or substituting for disordered renal function.
Pregnancy
Information about effects the drug may have on pregnant women or on a fetus. This field may be ommitted if the drug is not absorbed systemically and the drug is not known to have a potential for indirect harm to the fetus. It may contain information about the established pregnancy category classification for the drug. (That information is nominally listed in the teratogenic_effects field, but may be listed here instead.)8.1 Pregnancy Risk Summary Tekturna can cause fetal harm when administered to a pregnant woman. Use of drugs that act on the renin-angiotensin system during the second and third trimesters of pregnancy reduces fetal renal function and increases fetal and neonatal morbidity and death [see Clinical Considerations ] . Most epidemiologic studies examining fetal abnormalities after exposure to antihypertensive use in the first trimester have not distinguished drugs affecting the renin-angiotensin system from other antihypertensive agents. When pregnancy is detected, discontinue Tekturna as soon as possible. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major malformations and miscarriage in clinically recognized pregnancies is 2-4%, and 15-20%, respectively. Clinical Considerations Disease-Associated Maternal and/or Embryo/Fetal Risk Hypertension in pregnancy increases the maternal risk for pre-eclampsia, gestational diabetes, premature delivery, and delivery complications (e.g., need for cesarean section, and post-partum hemorrhage). Hypertension increases the fetal risk for intrauterine growth restriction and intrauterine death. Pregnant women with hypertension should be carefully monitored and managed accordingly. Fetal/Neonatal Adverse Reactions Use of drugs that act on the renin-angiotensin system in the second and third trimesters of pregnancy can result in the following: reduced fetal renal function leading to anuria and renal failure, oligohydramnios, fetal lung hypoplasia and skeletal deformations, including skull hypoplasia, hypotension, and death. In the unusual case that there is no appropriate alternative to therapy with drugs affecting the renin-angiotensin system for a particular patient, apprise the mother of the potential risk to the fetus. In patients taking Tekturna during pregnancy, perform serial ultrasound examinations to assess the intra- amniotic environment. Fetal testing may be appropriate, based on the week of gestation. Patients and physicians should be aware, however, that oligohydramnios may not appear until after the fetus has sustained irreversible injury. Closely observe infants with histories of in utero exposure to Tekturna for hypotension, oliguria, and hyperkalemia. If oliguria or hypotension occur in neonates with a history of in utero exposure to aliskiren, support blood pressure and renal perfusion. Exchange transfusions or dialysis may be required as a means of reversing hypotension and substituting for disordered renal function. Data Animal Data In developmental toxicity studies, pregnant rats and rabbits received oral aliskiren hemifumarate during organogenesis at doses up to 20 and 7 times the maximum recommended human dose (MRHD) based on body surface area (mg/m 2 ), respectively, in rats and rabbits. (Actual animal doses were up to 600 mg/kg/day in rats and up to 100 mg/kg/day in rabbits.) No teratogenicity was observed; however, fetal birth weight was decreased in rabbits at doses 3.2 times the MRHD based on body surface area (mg/m 2 ). Aliskiren was present in placentas, amniotic fluid and fetuses of pregnant rabbits.

Aliskiren was present in placentas, amniotic fluid and fetuses of pregnant rabbits. 8.2 Lactation Risk Summary There is no information regarding the presence of aliskiren in human milk, the effects on the breastfed infant, or the effects on milk production. Because of the potential for serious adverse reactions, including hypotension, hyperkalemia and renal impairment in nursing infants, advise a nursing woman that breastfeeding is not recommended during treatment with Tekturna. 8.4 Pediatric Use Tekturna is contraindicated in patients less than 2 years of age [see Contraindications ( 4 )]. Tekturna is indicated for treatment of hypertension in pediatric patients 6 years of age and older weighing 50 kg or more. The safety and effectiveness of aliskiren have been established in pediatric patients 6 years of age and older weighing 20 kg or more, but Tekturna is not approved in patients 6 years of age and older weighing 20 kg to less than 50 kg because of the lack of an appropriate dosage form. Use of Tekturna in pediatric patients 6 years and older is supported by evidence from a pharmacokinetic trial and two randomized, double-blind clinical trials in pediatric patients with hypertension 6 years to 17 years of age weighing 20 kg or more [see Clinical Pharmacology ( 12.3 ), Clinical Studies ( 14.4 ) ] . The safety and effectiveness of Tekturna have not been established in pediatric patients younger than 6 years of age and patients less than 20 kg. Avoid use in patients 2 years to less than 6 years and patients weighing less than 20 kg due to the limited information about aliskiren metabolism and exposures in this age group. No data are available in pediatric patients weighing less than 20 kg or in pediatric patients with a glomerular filtration rate <30 mL/min/1.73 m 2 . Juvenile Animal Toxicity Data Toxicology studies in juvenile animals the approximate human age equivalent of children less than 2 years of age identified 85- to 385-fold increased systemic exposure to aliskiren compared to adult rats. The increased aliskiren exposure in juvenile rats was attributed to immaturity in aliskiren drug transporters and metabolizing enzymes. Increased aliskiren exposures were associated with premature deaths. Although a definitive pathology-based cause of death could not be ascertained, the premature deaths were attributed to the immaturity in aliskiren metabolism. The nonclinical findings suggest a distinct age-dependent relationship between dose and exposure. Neonates with a history of in utero exposure to Tekturna If oliguria or hypotension occurs, direct attention toward support of blood pressure and renal perfusion. Exchange transfusions or dialysis may be required as a means of reversing hypotension and/or substituting for disordered renal function. 8.5 Geriatric Use Of the total number of patients receiving aliskiren in clinical studies, 1,275 (19%) were 65 years or older and 231 (3.4%) were 75 years or older. No overall differences in safety or effectiveness were observed between these subjects and younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out. 8.6 Renal Impairment Safety and effectiveness of Tekturna in patients with severe renal impairment [creatinine clearance (CrCl) less than 30 mL/min] have not been established as these patients were excluded in efficacy trials [see Clinical Studies ( 14 )].
