Kyzatrex TESTOSTERONE UNDECANOATE 150 mg Capsule, Liquid Filled, 120-count — NDC 80603-103-22 (Billing 80603-0103-22)

5 WARNINGS AND PRECAUTIONS - Polycythemia : Monitor hemoglobin or hematocrit approximately every 3 months to detect increased red blood cell mass and polycythemia. Discontinue KYZATREX® if necessary ( 5.1 ). Venous thromboembolism (VTE) : VTE, including deep vein thrombosis (DVT) and pulmonary embolism (PE) have been reported in patients using testosterone.

Discontinue KYZATREX® if VTE is suspected and initiate appropriate workup and management (5.2) Worsening of Benign Prostatic Hyperplasia (BPH) and Potential Risk of Prostate Cancer : Monitor patients for worsening of signs and symptoms of BPH. Evaluate patients for prostate cancer, including monitoring prostate specific antigen (PSA) prior to initiating and during treatment with androgens ( 5.3 ). Blood Pressure Increases: KYZATREX® can increase blood pressure, which can increase cardiovascular risk over time.

Measure blood pressure periodically. Not recommended for use in men with uncontrolled hypertension ( 5.4 ) Abuse of Testosterone and Monitoring of Serum Testosterone : If testosterone use at doses higher than recommended for the approved indication and in combination with other anabolic androgenic steroids is suspected, check serum testosterone concentration ( 5.5 ). Potential for Adverse Effects on Spermatogenesis : KYZATREX® may cause azoospermia ( 5.7 ).

Edema : Edema, with or without congestive heart failure (CHF), may occur in patients with pre-existing cardiac, renal, or hepatic disease. Discontinue KYZATREX® and initiate appropriate workup ( 5.9 ). Sleep Apnea : KYZATREX® may potentiate sleep apnea in those with risk factors ( 5.10 ) Lipid Changes : KYZATREX® may affect serum lipid profile.

Monitor patient lipid concentrations periodically; if necessary, adjust dosage of lipid lowering drug(s) or discontinue KYZATREX® ( 5.12 ).

5.1Polycythemia Androgens, including KYZATREX®, can cause increase in hemoglobin or hematocrit, reflective of increase in red blood cell mass. Check hematocrit prior to initiating KYZATREX®. An increase in red blood cell mass may increase the risk of thromboembolic events [see Warnings and Precautions ( 5.2 )].

Evaluate hematocrit approximately every 3 months while the patient is on KYZATREX®. If hematocrit becomes elevated, stop KYZATREX® until the hematocrit decreases to an acceptable concentration. If KYZATREX® is restarted and again causes hematocrit to become elevated, permanently discontinue KYZATREX®.

5.2Venous Thromboembolism There have been post-marketing reports of venous thromboembolic events, including deep vein thrombosis (DVT) and pulmonary embolism (PE), in patients using testosterone replacement products such as KYZATREX®. In the Testosterone Replacement therapy for Assessment of long-term Vascular Events and efficacy Response in hypogonadal men (TRAVERSE) Study, a randomized, double-blind, placebo-controlled, cardiovascular (CV) outcomes study, compared to placebo, topical testosterone gel was associated with a numerically higher incidence of VTE (1.7% vs 1.2%) which included DVT (0.6% vs 0.5%) and PE events (0.9% vs 0.5%) [see Adverse Reactions 6.1 )].

Evaluate patients who report symptoms of pain, edema, warmth, and erythema in the lower extremity for DVT and those who present with acute shortness of breath for PE. If a venous thromboembolic event is suspected, discontinue KYZATREX® and initiate appropriate workup and management [see Adverse Reactions ( 6.2 )].

5.3Worsening of Benign Prostatic Hyperplasia (BPH) and Potential Risk of Prostate Cancer Patients with BPH who are treated with androgens are at an increased risk for worsening of signs and symptoms of BPH. Monitor patients with BPH for worsening signs and symptoms. Patients treated with androgens may be at increased risk for prostate cancer.

Evaluate patients for prostate cancer prior to initiating and during treatment with androgens [see Contraindications (4)].

6.1Clinical Trial Experience 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 the clinical trials of another drug and may not reflect the rates observed in practice. The safety of KYZATREX® was evaluated in Study MRS-TU-2019EXT in 155 hypogonadal males [see Clinical Studies (14) ]. All patients initially received KYZATREX® 200 mg orally twice daily.

If needed, the dosage was titrated to 100 mg once daily in the morning or 100 mg, 300 mg, or 400 mg twice daily to achieve testosterone concentrations in the normal range . After the dosage titration period, patients continued their optimized dose for the remainder of the duration of the 6-month study. The mean duration of exposure was 168 days (range: 1 to 180 days).

The median age was 52 years (range: 22 to 66 years); 77% were White, 19% were Black, 3% were Asian, and 2% were American Indian, Alaskan Native or Other. Table 2 summarizes adverse reactions reported in ≥2% of patients in this 6-month study. Table 2: Adverse Reactions in ≥ 2% of Patients Receiving KYZATREX® in STUDY MRS-TU-2019EXT Adverse Reaction N = 155 n (%) Hypertensión Based upon blood pressure cuff measurements 4 (2.6) One (0.8%) patient who received KYZATREX® experienced an adverse reaction (acne) that lead to premature discontinuation from the study.

In a 12-month, open-label study in hypogonadal adult males (N=212) who received KYZATREX® 200 mg once daily to 400 mg twice daily (n=202) the following additional adverse reactions were reported: headache, arthralgia, diarrhea, hemoglobin increased, anxiety, constipation, peripheral edema, and PSA increased. Blood Pressure Increases In Study MRS-TU-2019EXT, 24-hour ambulatory blood pressure monitoring (ABPM) was conducted in 155 male patients, 135 of whom completed the study. ABPM was conducted at 3 distinct 24-hour time periods: at baseline and following approximately 4 months and 6 months of treatment with KYZATREX®.

A total of 151 patients had acceptable 24-hour ABPM recordings at both time periods. In that group, the mean change in systolic BP from Baseline to 4 months and 6 months was + 1.7 mm Hg (95% CI 0.3, 3.1) and 1.8 mm Hg (95% CI 0.3, 3.2), respectively. In that group, the mean change in diastolic BP from Baseline to 4 months and 6 months was 0.6 mm Hg (95% CI -0.3, 1.6) and 0.6 mm Hg (95% CI -0.4, 1.6), respectively.

In patients with a history of hypertension on antihypertensive therapy at baseline, the mean ABPM systolic blood pressure increased from Baseline to 4 months and 6 months by 3.4 mm Hg (95% CI 1.0, 5.9) and 3.1 mm Hg (95% CI 0.6, 5.6), respectively (n=49). In patients with no history of hypertension at baseline, the mean systolic blood pressure from Baseline increased by 0.7 mm Hg (95% CI -1.0, 2.4) at 4 months and 1.0 mm Hg (95% CI -0.7, 2.8), at six months respectively (n =90).

7 DRUG INTERACTIONS - Insulin: In patients with diabetes, concomitant use with KYZATREX® may decrease blood glucose and insulin requirements ( 7.1 ). Oral Anticoagulants: Concomitant use with KYZATREX® may cause changes in anticoagulant activity. Monitor International Normalized Ratio (INR) and prothrombin time (PT) frequently ( 7.2 ).

Corticosteroids: Concomitant use with KYZATREX® may result in increased fluid retention. Use with caution, particularly in patients with cardiac, renal, or hepatic disease ( 7.3 ). Drugs that May Also Increase Blood Pressure: Concomitant use with KYZATREX® may lead to additional increases in blood pressure ( 7.4 ).

7.1Insulin Changes in insulin sensitivity or glycemic control may occur in patients treated with androgens. In diabetic patients, the metabolic effects of androgens may decrease blood glucose and therefore necessitate a decrease in the dose of anti-diabetic medication.

7.2Oral Vitamin K Antagonist Anticoagulants Changes in anticoagulant activity may be seen with androgens; therefore, more frequent monitoring of international normalized ratio (INR) and prothrombin time are recommended in patients taking warfarin, especially at the initiation and termination of androgen therapy.

7.3Corticosteroids The concurrent use of testosterone with corticosteroids may result in increased fluid retention and requires careful monitoring particularly in patients with cardiac, renal, or hepatic disease.

7.4Medications that May Also Increase Blood Pressure Some prescription medications and nonprescription analgesic and cold medications contain drugs known to increase blood pressure. Concomitant administration of these medications with KYZATREX® may lead to additional increases in blood pressure [see Warnings and Precautions (5.4)] .

9 DRUG ABUSE AND DEPENDENCE -

9.1Controlled Substance KYZATREX® contains testosterone undecanoate, a Schedule III controlled substance

9.2Abuse Drug abuse is intentional non-therapeutic use of a drug, even once, for its rewarding psychological and physiological effects. Abuse and misuse of testosterone are seen in male and female adults and adolescents. Testosterone, often in combination with other anabolic androgenic steroids, and not obtained by prescription through a pharmacy, may be abused by athletes and bodybuilders.

There have been reports of misuse by men taking higher doses of legally obtained testosterone than prescribed and continuing testosterone despite adverse events or against medical advice. Abuse-Related Adverse Reactions Serious adverse reactions have been reported in individuals who abuse anabolic androgenic steroids and include cardiac arrest, myocardial infarction, hypertrophic cardiomyopathy, congestive heart failure, cerebrovascular accident, hepatotoxicity, and serious psychiatric manifestations, including major depression, mania, paranoia, psychosis, delusions, hallucinations, hostility, and aggression.

The following adverse reactions have also been reported in men: transient ischemic attacks, convulsions, hypomania, irritability, dyslipidemias, testicular atrophy, subfertility, and infertility. The following additional adverse reactions have been reported in women: hirsutism, virilization, deepening of voice, clitoral enlargement, breast atrophy, male-pattern baldness, and menstrual irregularities. The following adverse reactions have been reported in male and female adolescents: premature closure of bony epiphyses with termination of growth, and precocious puberty.

Because these reactions are reported voluntarily from a population of uncertain size and may include abuse of other agents, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

9.3Dependence Behaviors Associated with Addiction Continued abuse of testosterone and other anabolic steroids leading to addiction is characterized by the following behaviors: Taking greater dosages than prescribed Continued drug use despite medical and social problems due to drug use Spending significant time to obtain the drug when supplies of the drug are interrupted Giving a higher priority to drug use than other obligations Having difficulty in discontinuing the drug despite desires and attempts to do so Experiencing withdrawal symptoms upon abrupt discontinuation of use Physical dependence is characterized by withdrawal symptoms after abrupt drug discontinuation or a significant dose reduction of a drug.

Individuals taking supratherapeutic doses of testosterone may experience withdrawal symptoms lasting for weeks or months, which may include depressed mood, major depression, fatigue, craving, restlessness, irritability, anorexia, insomnia, decreased libido, and hypogonadotropic hypogonadism. Drug dependence in individuals using approved doses of testosterone for approved indications has not been documented.
