Warnings and Precautions (5.7) 10/2016
1 INDICATIONS AND USAGE
Cristerone T is indicated for Cristerone T replacement therapy in adult males for conditions associated with a deficiency or absence of endogenous Cristerone T.
Cristerone T should only be used in patients who require Cristerone T replacement therapy and in whom the benefits of the product outweigh the serious risks of pulmonary oil microembolism and anaphylaxis.
Limitations of use:
Cristerone T (testosterone undecanoate) injection is an androgen indicated for Cristerone T replacement therapy in adult males for conditions associated with a deficiency or absence of endogenous Cristerone T:
o Primary hypogonadism (congenital or acquired) (1)
o Hypogonadotropic hypogonadism (congenital or acquired) (1)
Cristerone T should only be used in patients who require Cristerone T replacement therapy and in whom the benefits of the product outweigh the serious risks of pulmonary oil microembolism and anaphylaxis (1).
Limitations of use:
2 DOSAGE AND ADMINISTRATION
Prior to initiating Cristerone T, confirm the diagnosis of hypogonadism by ensuring that serum Cristerone T concentrations have been measured in the morning on at least two separate days and that these serum Cristerone T concentrations are below the normal range.
Cristerone T is for intramuscular use only. Dosage titration is not necessary.
Inject Cristerone T deeply into the gluteal muscle following the usual precautions for intramuscular administration; care must be taken to avoid intravascular injection . Intravascular injection of Cristerone T may lead to pulmonary oil microembolism .
The recommended dose of Aveed is 3 mL (750 mg) injected intramuscularly, followed by 3 mL (750 mg) injected after 4 weeks, then 3 mL (750 mg) injected every 10 weeks thereafter.
2.2 Preparation Instructions
Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit.
Carefully remove the gray plastic cap from the top of the vial by lifting it up from the edges with your fingers or by pushing the bottom edge of the cap upward using the top of your thumb. Remove only the gray plastic cap while leaving the aluminum metal ring and crimp seal around the gray rubber stopper in place. To facilitate the removal of medication from the vial, you can draw 3 mL of air into the syringe and inject it through the gray rubber stopper into the vial to create positive pressure within the vial chamber.
Withdraw 3 mL of Cristerone T solution from the vial. Expel excess air bubbles from the syringe. Replace the syringe needle used to draw up the solution from the vial with a new intramuscular needle and inject. Discard any unused portion in the vial.
2.3 Administration Instructions
The site for injection for Cristerone T is the gluteus medius muscle site located in the upper outer quadrant of the buttock. Care must be taken to avoid the needle hitting the superior gluteal arteries and sciatic nerve. Between consecutive injections, alternate the injection site between left and right buttock.
Figure 1: Identifying the injection site
Following antiseptic skin preparation, enter the muscle and maintain the syringe at a 90° angle with the needle in its deeply imbedded position. Grasp the barrel of the syringe firmly with one hand. With the other hand, pull back on the plunger and aspirate for several seconds to ensure that no blood appears. If any blood is drawn into the syringe, immediately withdraw and discard the syringe and prepare another dose.
If no blood is aspirated, reinforce the current needle position to avoid any movement of the needle and slowly (over 60 to 90 seconds) depress the plunger carefully and at a constant rate, until all the medication has been delivered. Be sure to depress the plunger completely with sufficient controlled force. Withdraw the needle.
Immediately upon removal of the needle from the muscle, apply gentle pressure with a sterile pad to the injection site. If there is bleeding at the site of injection, apply a bandage.
Following each injection of Cristerone T, observe patients in the healthcare setting for 30 minutes in order to provide appropriate medical treatment in the event of serious POME reactions or anaphylaxis (5.1).
3 DOSAGE FORMS AND STRENGTHS
750 mg/3 mL (250 mg/mL) Cristerone T undecanoate sterile injectable solution is provided in an amber glass, single use vial with silver-colored crimp seal and gray plastic cap.
Cristerone T should not be used in any of the following patients:
5 WARNINGS AND PRECAUTIONS
5.1 Serious Pulmonary Oil Microembolism (POME) Reactions and Anaphylaxis
Serious POME reactions, involving cough, urge to cough, dyspnea, hyperhidrosis, throat tightening, chest pain, dizziness, and syncope, have been reported to occur during or immediately after the injection of intramuscular Cristerone T undecanoate 1000 mg (4 mL). The majority of these events lasted a few minutes and resolved with supportive measures; however, some lasted up to several hours and some required emergency care and/or hospitalization. To minimize the risk of intravascular injection of Cristerone T, care should be taken to inject the preparation deeply into the gluteal muscle, being sure to follow the recommended procedure for intramuscular administration .
In addition to serious POME reactions, episodes of anaphylaxis, including life-threatening reactions, have also been reported to occur following the injection of intramuscular Cristerone T undecanoate.
Both serious POME reactions and anaphylaxis can occur after any injection of Cristerone T undecanoate during the course of therapy, including after the first dose. Patients with suspected hypersensitivity reactions to Cristerone T should not be re-treated with Cristerone T.
Following each injection of Cristerone T, observe patients in the healthcare setting for 30 minutes in order to provide appropriate medical treatment in the event of serious POME reactions and anaphylaxis.
5.2 Cristerone T Risk Evaluation and Mitigation Strategy Program
Cristerone T is available only through a restricted program called the Cristerone T REMS Program because of the risk of serious POME and anaphylaxis.
Notable requirements of the Cristerone T REMS Program include the following:
Further information is available at www. AveedREMS.com or call 1-855-755-0494.
5.3 Worsening of Benign Prostatic Hyperplasia and Potential Risk of Prostate Cancer
Patients with BPH treated with androgens are at an increased risk of worsening of signs and symptoms of BPH. Monitor patients with BPH for worsening signs and symptoms.
Patients treated with androgens may be at an increased risk for prostate cancer. Evaluate patients for prostate cancer prior to initiating and during treatment with androgens .
Increases in hematocrit, reflective of increases in red blood cell mass, may require discontinuation of Cristerone T.
Check hematocrit prior to initiating Cristerone T treatment. It would be appropriate to re-evaluate the hematocrit 3 to 6 months after starting Cristerone T treatment, and then annually. If hematocrit becomes elevated, stop therapy until hematocrit decreases to an acceptable level. An increase in red blood cell mass may increase the risk of thromboembolic events.
5.5 Venous Thromboembolism
There have been postmarketing reports of venous thromboembolic events, including deep vein thrombosis and pulmonary embolism (PE), in patients using Cristerone T products, such as Cristerone T. 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 treatment with Cristerone T and initiate appropriate workup and management.
5.6 Cardiovascular Risk
Long term clinical safety trials have not been conducted to assess the cardiovascular outcomes of Cristerone T replacement therapy in men. To date, epidemiologic studies and randomized controlled trials have been inconclusive for determining the risk of major adverse cardiovascular events (MACE), such as non-fatal myocardial infarction, non-fatal stroke, and cardiovascular death, with the use of Cristerone T compared to non-use. Some studies, but not all, have reported an increased risk of MACE in association with use of Cristerone T replacement therapy in men. Patients should be informed of this possible risk when deciding whether to use or to continue to use Cristerone T.
5.7 Abuse of Cristerone T and Monitoring of SerumTestosterone Concentrations
Cristerone T has been subject to abuse, typically at doses higher than recommended for the approved indication and in combination with other anabolic androgenic steroids. Anabolic androgenic steroid abuse can lead to serious cardiovascular and psychiatric adverse reactions .
If Cristerone T abuse is suspected, check serum Cristerone T concentrations to ensure they are within therapeutic range. However, Cristerone T levels may be in the normal or subnormal range in men abusing synthetic Cristerone T derivatives. Counsel patients concerning the serious adverse reactions associated with abuse of Cristerone T and anabolic androgenic steroids. Conversely, consider the possibility of Cristerone T and anabolic androgenic steroid abuse in suspected patients who present with serious cardiovascular or psychiatric adverse events.
5.8 Use in Women
Due to lack of controlled evaluations in women and potential virilizing effects, Cristerone T is not indicated for use in women.
5.9 Potential for Adverse Effects on Spermatogenesis
With large doses of exogenous androgens, including Cristerone T, spermatogenesis may be suppressed through feedback inhibition of pituitary follicle- stimulating hormone which could possibly lead to adverse effects on semen parameters including sperm count.
5.10 Hepatic Adverse Effects
Prolonged use of high doses of orally active 17-alpha-alkyl androgens (e.g., methyltestosterone) has been associated with serious hepatic adverse effects (peliosis hepatis, hepatic neoplasms, cholestatic hepatitis, and jaundice). Peliosis hepatis can be a life-threatening or fatal complication. Long-term therapy with intramuscular Cristerone T enanthate, which elevates blood levels for prolonged periods, has produced multiple hepatic adenomas. Cristerone T is not known to produce these adverse effects. Nonetheless, patients should be instructed to report any signs or symptoms of hepatic dysfunction (e.g., jaundice). If these occur, promptly discontinue Cristerone T while the cause is evaluated.
Androgens, including Cristerone T, may promote retention of sodium and water. Edema with or without congestive heart failure may be a serious complication in patients with preexisting cardiac, renal, or hepatic disease. In addition to discontinuation of the drug, diuretic therapy may be required.
Gynecomastia occasionally develops and occasionally persists in patients being treated for hypogonadism .
5.13 Sleep Apnea
The treatment of hypogonadal men with Cristerone T products may potentiate sleep apnea in some patients, especially those with risk factors such as obesity or chronic lung diseases.
Changes in serum lipid profile may require dose adjustment of lipid lowering drugs or discontinuation of Cristerone T therapy.
Androgens, including Cristerone T, should be used with caution in cancer patients at risk of hypercalcemia. Regular monitoring of serum calcium concentrations is recommended in these patients.
5.16 Decreased Thyroxine-binding Globulin
Androgens, including Cristerone T, may decrease concentrations of thyroxine-binding globulin, resulting in decreased total T4 serum concentrations and increased resin uptake of T3 and T4. Free thyroid hormone concentrations remain unchanged, however, and there is no clinical evidence of thyroid dysfunction.
6 ADVERSE REACTIONS
The most commonly reported adverse reactions are acne, injection site pain, prostatic specific antigen (PSA) increased, estradiol increased, hypogonadism, fatigue, irritability, hemoglobin increased, insomnia, and mood swings (6.1).
To report SUSPECTED ADVERSE REACTIONS, contact Endo Pharmaceuticals at 1-800-462-3636 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch .
6.1 Clinical 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 clinical practice.
Cristerone T was evaluated in an 84-week clinical study using a dose regimen of 750 mg (3 mL) at initiation, at 4 weeks, and every 10 weeks thereafter in 153 hypogonadal men. The most commonly reported adverse reactions (>2%) were: acne (5.2%), injection site pain (4.6%), prostate specific antigen increased (4.6%), hypogonadism (2.6%) and estradiol increased (2.6%).
Table 1 presents adverse reactions reported by ≥1% of patients in the 84-week clinical study.
Adverse Reactions Reported in at Least 1% of Patients in the 84-Week Clinical Study of Cristerone T
* Prostate specific antigen increased defined as a serum PSA concentration >4 ng/mL.
In the 84-week clinical trial, 7 patients (4.6%) discontinued treatment because of adverse reactions. Adverse reactions leading to discontinuation included: hematocrit increased, estradiol increased, prostatic specific antigen increased, prostate cancer, mood swings, prostatic dysplasia, acne, and deep vein thrombosis.
During the 84-week clinical trial, the average serum PSA increased from 1.0 ± 0.8 ng/mL at baseline to 1.5 ± 1.3 ng/mL at the end of study. Fourteen patients (10.9%) in whom the baseline PSA was < 4 ng/mL had a post-baseline serum PSA of > 4 ng/mL during the 84-week treatment period.
A total of 725 hypogonadal men received intramuscular Cristerone T undecanoate in a total of 7 controlled clinical trials. In these clinical trials, the dose and dose frequency of intramuscular Cristerone T undecanoate varied from 750 mg to 1000 mg, and from every 9 weeks to every 14 weeks. Several of these clinical trials incorporated additional doses upon initiation of therapy (e.g., loading doses). In addition to those adverse reactions noted in Table 1, the following adverse events were reported by at least 3% of patients in these trials, irrespective of the investigator’s assessment of relationship to study medication: sinusitis, prostatitis, arthralgia, nasopharyngitis, upper respiratory tract infection, bronchitis, back pain, hypertension, diarrhea and headache.
Pulmonary Oil Microembolism (POME) and Anaphylaxis in Controlled Clinical Studies
Adverse events attributable to pulmonary oil microembolism and anaphylaxis were reported in a small number of patients in controlled clinical trials. In the 84-week clinical trial of Cristerone T, 1 patient experienced a mild coughing fit lasting 10 minutes after his third injection, which was retrospectively attributed to POME. In another clinical trial of intramuscular Cristerone T undecanoate (1000 mg), a hypogonadal male patient experienced the urge to cough and respiratory distress at 1 minute after his tenth injection, which was also retrospectively attributed to POME.
During a review that involved adjudication of all cases meeting specific criteria, 9 POME events in 8 patients and 2 events of anaphylaxis among 3,556 patients treated with intramuscular Cristerone T undecanoate in 18 clinical trials were judged to have occurred.
6.2 Postmarketing Experience
The following adverse reactions have been identified during post-approval use of Cristerone T. Because the reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
Pulmonary Oil Microembolism (POME) and Anaphylaxis
Serious pulmonary oil microembolism (POME) reactions, involving cough, urge to cough, dyspnea, hyperhidrosis, throat tightening, chest pain, dizziness, and syncope, have been reported to occur during or immediately after the injection of intramuscular Cristerone T undecanoate 1000 mg (4 mL) in post-approval use outside the United States. The majority of these events lasted a few minutes and resolved with supportive measures; however, some lasted up to several hours and some required emergency care and/or hospitalization.
In addition to serious POME reactions, episodes of anaphylaxis, including life-threatening reactions, have also been reported to occur following the injection of intramuscular Cristerone T undecanoate in post-approval use outside of the United States.
Both serious POME reactions and anaphylaxis have been reported to occur after any injection of Cristerone T undecanoate during the course of therapy, including after the first dose.
The following treatment emergent adverse events or adverse reactions have been identified during post-marketing clinical trials and during post-approval use of intramuscular Cristerone T undecanoate. In most cases, the dose being used was 1000 mg.

7 DRUG INTERACTIONS
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, may necessitate a decrease in the dose of anti-diabetic medication.
7.2 Oral Anticoagulants
Changes in anticoagulant activity may be seen with androgens, therefore more frequent monitoring of international normalized ratio and prothrombin time are recommended in patients taking warfarin, especially at the initiation and termination of androgen therapy.
The concurrent use of Cristerone T with corticosteroids may result in increased fluid retention and requires careful monitoring, particularly in patients with cardiac, renal or hepatic disease.
8 USE IN SPECIFIC POPULATIONS
Geriatric Patients: There are insufficient long-term safety data to assess the potential risks of cardiovascular disease and prostate cancer.
Pregnancy Category X: Aveed is contraindicated in pregnant women or in women who may become pregnant. Cristerone T is teratogenic and may cause fetal harm. Exposure of a fetus to androgens, such as Cristerone T, may result in varying degrees of virilizations. If this drug is used in pregnancy or if the patient becomes pregnant while taking this drug, the patient should be made aware of the potential hazard to the fetus.
8.3 Nursing Mothers
Although it is not known how much Cristerone T transfers into human milk, Cristerone T is contraindicated in nursing women because of the potential for serious adverse reactions in nursing infants.
8.4 Pediatric Use
Safety and effectiveness of Cristerone T in pediatric patients less than 18 years old have not been established. Improper use may result in acceleration of bone age and premature closure of epiphyses.
8.5 Geriatric Use
There have not been sufficient numbers of geriatric patients in controlled clinical studies with Cristerone T to determine whether efficacy or safety in those over 65 years of age differs from younger subjects. Of the153 patients enrolled in the pivotal clinical study utilizing Cristerone T, 26 were over 65 years of age. Additionally, there are insufficient long-term safety data in geriatric patients to assess the potentially increased risk of cardiovascular disease and prostate cancer.
Geriatric patients treated with androgens may also be at risk for worsening of signs and symptoms of BPH .
8.6 Renal Impairment
No studies were conducted in patients with renal impairment.
8.7 Hepatic Impairment
No studies were conducted in patients with hepatic impairment.
9 DRUG ABUSE AND DEPENDENCE
9.1 Controlled Substance
Cristerone T contains Cristerone T, a Schedule III controlled substance in the Controlled Substances Act.
Drug abuse is intentional non-therapeutic use of a drug, even once, for its rewarding psychological and physiological effects. Abuse and misuse of Cristerone T 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 of men taking higher doses of legally obtained Cristerone T than prescribed and continuing Cristerone T 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.
Behaviors Associated with Addiction
Continued abuse of Cristerone T and other anabolic steroids, leading to addiction is characterized by the following behaviors:
Physical dependence is characterized by withdrawal symptoms after abrupt drug discontinuation or a significant dose reduction of a drug. Individuals taking supratherapeutic doses of Cristerone T may experience withdrawal symptoms lasting for weeks or months which include depressed mood, major depression, fatigue, craving, restlessness, irritability, anorexia, insomnia, decreased libido and hypogonadotropic hypogonadism.
Drug dependence in individuals using approved doses of Cristerone T for approved indications has not been documented.
There have been no reports of overdosage in the Cristerone T clinical trials. There is one report of acute overdosage with use of an approved injectable Cristerone T product: this subject had serum Cristerone T levels of up to 11,400 ng/dL with a cerebrovascular accident.
Treatment of overdosage would consist of discontinuation of Cristerone T together with appropriate symptomatic and supportive care.
Cristerone T (testosterone undecanoate) injection contains Cristerone T undecanoate (17β-undecanoyloxy-4-androsten-3-one) which is an ester of the androgen, Cristerone T. Cristerone T is formed by cleavage of the ester side chain of Cristerone T undecanoate.
Cristerone T undecanoate is a white to off-white crystalline substance. The empirical formula of Cristerone T undecanoate is C30H48O3 and a molecular weight of 456.7. The structural formula is:
FIGURE 2: Cristerone T Undecanoate
C30H48O3 MW: 456.7
Cristerone T is a clear, yellowish, sterile oily solution containing Cristerone T undecanoate, a Cristerone T ester, for intramuscular injection. Each single use vial contains 3 mL of 250 mg/mL Cristerone T undecanoate solution in a mixture of 1500 mg of benzyl benzoate and 885 mg of refined castor oil.
12 CLINICAL PHARMACOLOGY
12.1 Mechanism of Action
Endogenous androgens, including Cristerone T and dihydrotestosterone are responsible for the normal growth and development of the male sex organs and for maintenance of secondary sex characteristics. These effects include the growth and maturation of prostate, seminal vesicles, penis, and scrotum; the development of male hair distribution, such as facial, pubic, chest, and axillary hair; laryngeal enlargement, vocal cord thickening, and alterations in body musculature and fat distribution.
Male hypogonadism, a clinical syndrome resulting from insufficient secretion of Cristerone T, has two main etiologies. Primary hypogonadism is caused by defects of the gonads, such as Klinefelter’s syndrome or Leydig cell aplasia, whereas secondary hypogonadism is the failure of the hypothalamus (or pituitary) to produce sufficient gonadotropins (FSH, LH).
Cristerone T 750 mg delivers physiologic amounts of Cristerone T, producing circulation Cristerone T concentrations that approximate normal concentrations (300-1000 ng/dL) seen in healthy men.
Cristerone T esters in oil injected intramuscularly are absorbed from the lipid phase. Cleavage of the undecanoic acid side chain of Cristerone T by tissue esterases releases Cristerone T.
Following intramuscular injection of 750 mg of Cristerone T, serum Cristerone T concentrations reach a maximum after a median of
7 days (range 4 – 42 days) then slowly decline (Figure 3). Steady state serum Cristerone T concentration was achieved with the 3rd injection of Cristerone T at 14 weeks.
Figure 3 shows the mean serum total Cristerone T concentration-time profile during the 3rd injection interval (at steady state, 14-24 weeks) for hypogonadal men (less than 300 ng/dL) given 750 mg Cristerone T at initiation, at 4 weeks, and every 10 weeks thereafter. Intramuscular injection of 750 mg of Cristerone T generates mean steady state serum total Cristerone T concentrations in the normal range for 10 weeks.
FIGURE 3: Mean (SD) Serum Total Cristerone T
Concentrations (ng/dL) at 14-24 Weeks
Circulating Cristerone T is chiefly bound in the serum to sex hormone-binding globulin (SHBG) and albumin.
Approximately 40% of Cristerone T in plasma is bound to SHBG, 2% remains unbound (free), and the rest is loosely bound to albumin and other proteins.
Cristerone T undecanoate is metabolized to Cristerone T via ester cleavage of the undecanoate group. The mean (SD) maximum concentration of Cristerone T undecanoate was 90.9 (68.8) ng/dL on Day 4 following injection of Cristerone T. Cristerone T undecanoate was nearly undetectable 42 days following injection of Cristerone T.
Cristerone T is metabolized to various 17-keto steroids through two different pathways. The major active metabolites of Cristerone T are estradiol and DHT.
DHT concentrations increased in parallel with Cristerone T concentrations during Cristerone T treatment. Average DHT concentrations during a dosing interval ranged from 244 to 451 ng/dL. The mean DHT:T ratios ranged from 0.05 to 0.07.
There is considerable variation in the half-life of Cristerone T as reported in the literature, ranging from 10 to 100 minutes. About 90% of a Cristerone T dose given intramuscularly is excreted in the urine as glucuronic and sulfuric acid-conjugates of Cristerone T or as metabolites. About 6% of a dose is excreted in the feces, mostly in the unconjugated form. Inactivation of Cristerone T occurs primarily in the liver.
Effect of Body Weight and Body Mass Index (BMI)
Analysis of serum Cristerone T concentrations from 117 hypogonadal men in the 84-week clinical study of Cristerone T indicated that serum Cristerone T concentrations achieved were inversely correlated with the patient’s body weight. In 60 patients with pretreatment body weight of ≥100 kg, the mean (±SD) serum Cristerone T average concentration was 426 ± 104 ng/dL. A higher serum Cristerone T average concentration (568 ± 139 ng/dL) was observed in 57 patients weighing 65 to 100 kg. A similar trend was also observed for maximum serum Cristerone T concentrations.
In 70 patients with pretreatment body mass index of >30 kg/m2, the mean (±SD) serum Cristerone T average concentration was
445 ± 116 ng/dL. Higher serum Cristerone T average concentrations (579 ± 101 ng/dL and 567± 155ng/dL) were observed in patients with BMIs <26 kg/m2 and 26 to 30 kg/m2,respectively. A similar trend was also observed for maximum serum Cristerone T concentrations.
13 NONCLINICAL TOXICOLOGY
13.1 Carcinogenesis and Mutagenesis and Impairment of Fertility
Cristerone T has been tested by subcutaneous injection and implantation in mice and rats. In mice, the implant induced cervical-uterine tumors, which metastasized in some cases. There is suggestive evidence that injection of Cristerone T into some strains of female mice increases their susceptibility to hepatoma. Cristerone T is also known to increase the number of tumors and decrease the degree of differentiation of chemically induced carcinomas of the liver in rats.
Mutagenic effects of Cristerone T undecanoate were not detected in a battery of in vitro tests including bacterial mutation assays (Ames test) and chromosomal aberration tests in human lymphocytes. Cristerone T undecanoate was also negative in an in vivo bone marrow micronucleus assay in mice. Cristerone T was negative in the in vitro Ames and in the in vivo mouse micronucleus assays.
Impairment of Fertility
The administration of exogenous Cristerone T has been reported to suppress spermatogenesis in the rat, dog and non-human primates, which was reversible on cessation of the treatment.
14 CLINICAL STUDIES
14.1 Cristerone T Replacement Therapy
Cristerone T was evaluated for efficacy in an 84-week, single-arm, open-label, multicenter study of 130 hypogonadal men. Eligible patients weighed at least 65 kg, were 18 years of age and older (mean age 54.2 years), and had a morning serum total Cristerone T concentrations <300 ng/dL (mean screening Cristerone T concentration 215 ng/dL). Patients were Caucasian (74.6%), Black (12.3%), Hispanic (10.8%) and of Other ethnicities (2.3%). The mean body mass index was 32 kg/m2.
All patients received injections of Cristerone T 750 mg at baseline, at 4 weeks, and then every 10 weeks thereafter.
The primary endpoint was the percentage of patients with average serum total Cristerone T concentration (Cavg) within the normal range (300-1000 ng/dL) after the third injection, at steady state.
The secondary endpoint was the percentage of patients with maximum total Cristerone T concentration (Cmax) above three pre-determined limits: greater than 1500 ng/dL, between 1800 and 2499 ng/dL, and greater than 2500 ng/dL.
A total of 117 out of 130 hypogonadal men completed study procedures through Week 24 and were included in the evaluation of Cristerone T pharmacokinetics after the third Cristerone T injection. Ninety-four percent (94%) of patients maintained a Cavg within the normal range (300 to 1000 ng/dL). The percentages of patients with Cavg below the normal range (less than 300 ng/dL) and above the normal range (greater than 1000 ng/dL) were 5.1% and 0.9%, respectively.
Table 2 summarizes the mean (SD) serum total Cristerone T pharmacokinetic parameters at steady state for these 117 patients.
Mean (SD) Serum Total Cristerone T Concentrations at Steady State
Cavg = average concentration; Cmax = maximum concentration; Cmin = minimum concentration
The percentage of patients with Cmax >1500 ng/dL was 7.7%. No patient had a Cmax >1800 ng/dL.
