FDA approves oral testosterone capsule for men with hypogonadism

The FDA on Wednesday approved testosterone undecanoate in an oral capsule to treat men with certain forms of hypogonadism, the agency announced in a press release.

The approval marks the first new oral testosterone replacement product in more than 60 years. The indication is for men with low testosterone levels due to specific medical conditions, such as Klinefelter syndrome or tumors that have damaged the pituitary gland. This oral testosterone undecanoate (Jatenzo, Clarus Therapeutics) should not be used to treat men with “age-related hypogonadism,” in which testosterone levels decline due to aging, even if these men have symptoms that appear to be related to low testosterone, according to the FDA, which stated that the drug’s benefits do not outweigh its risks for that use.Testosterone decanoate Uses
Jatenzo’s oral route of administration provides an important addition to current treatment options available for men with certain hypogonadal conditions who up until now have most commonly been treated with testosterone products that are applied to the skin or injected,” Hylton V. Joffe, MD, MMSc, director of the division of bone, reproductive and urologic products in the FDA’s Center for Drug Evaluation and Research, said in the release. “But it’s important to emphasize that this drug should not, like other testosterone treatments, be used to treat older men with ‘age-related hypogonadism.’ The benefits of testosterone therapy, including Jatenzo, have not been established for this use, and Jatenzo’s effects on raising blood pressure can increase the risks of heart attack, stroke and cardiovascular death in this population.”

The efficacy of Jatenzo was demonstrated in a 4-month clinical trial involving 166 men with hypogonadism. Study participants initially were given Jatenzo at a dose of 237 mg twice per day, and the dose was adjusted downward or upward to a maximum of 396 mg twice per day on the basis of testosterone levels. At the end of the study, 87% of men treated with the oral testosterone undecanoate achieved an average testosterone level within the normal range, which was the primary study endpoint.

In an interview conducted before a presentation on oral testosterone undecanoate at the Androgen Society annual meeting in New Orleans this month, Ronald Swerdloff, MD, professor of medicine, endocrinology, metabolism and nutrition at the David Geffen School of Medicine at UCLA and chief of the division of endocrinology at Harbor UCLA Medical Center, told Endocrine Today that the agent has “excellent pharmacokinetics” and, when taken with meals, has few unanticipated adverse effects. Development of the drug, he said, has been complex due to challenges associated with oral dosing. The formulation of testosterone undecanoate, however, reduces a dietary fat effect and the variability of testosterone response, he said.
