  • Striant is contraindicated in men with carcinoma of the breast or known or suspected carcinoma of the prostate [see Warnings and Precautions (5.2) and Adverse Reactions (6.1)].
  • Striant is contraindicated in women who are or may become pregnant, or who are breastfeeding. Striant may cause fetal harm when administered to a pregnant woman. Striant may cause serious adverse reactions in nursing infants. Exposure of a fetus or nursing infant to androgens may result in varying degrees of virilization [see Use in Specific Populations (8.1, 8.3)].

Nonclinical Toxicology

Carcinogenesis, Mutagenesis, Impairment of Fertility


Testosterone 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 testosterone into some strains of female mice increases their susceptibility to hepatoma. Testosterone is also known to increase the number of tumors and decrease the degree of differentiation of chemically induced carcinomas of the liver in rats.


Testosterone was negative in the in vitro Ames and in the in vivo mouse micronucleus assays.

Impairment of Fertility

The administration of exogenous testosterone has been reported to suppress spermatogenesis in the rat, dog and non human primates, which was reversible on cessation of the treatment.

Clinical Studies

Clinical Trials in Adult Hypogonadal Males

Striant was evaluated in a multicenter, open-label Phase 3 trial in 98 hypogonadal men. In this study, 30 mg of Striant was administered buccally twice daily for 12 weeks. The mean age was 53.6 years (range 20 to 75 years). Overall, 69% of patients were Caucasian, 9% were African-American, 15% were Hispanic, 4% were Asian, and 2% were of another ethnic origin. At baseline, 10% of patients reported current use of tobacco and 42% drank alcohol.

Of 82 patients who completed the trial and had sufficient data for full analysis, 86.6% had mean serum testosterone concentration (Cavg(0-24)) values within the physiologic range (300-1050 ng/dL).

The mean (±SD) time-averaged steady-state daily testosterone concentration (Cavg(0-24)) at Day 84 was 520 (±205) ng/dL compared with a mean of 149 (±99) ng/dL at Baseline. The mean (±SD) maximum testosterone concentration (Cmax) at Day 84 was 970 (±442) ng/dL. At Day 84, the mean percentage of time over the 24-hour sampling period that total testosterone concentrations remained within the normal range of 300-1050 ng/dL was 76%.

Figure 3 shows the mean total testosterone serum concentration versus time curves on Day 84 (after 12 weeks of Striant treatment).

Figure 3. Mean (SD) total testosterone concentration-time curves on Day 84 (after 12 weeks of Striant treatment, n=82)

Mean DHT concentrations increased in parallel with testosterone concentrations, with the total testosterone/DHT ratio (9-12) indicating no alteration in metabolism of testosterone to DHT in testosterone deficient men treated with Striant.

During continuous treatment there was no accumulation of testosterone, and mean total testosterone, free testosterone, and DHT were maintained within their physiologic ranges.
