Clarus Therapeutics’ Oral Testosterone Approved

Share

FDA has approved a Clarus Therapeutics NDA for Jatenzo (testosterone undecanoate), an oral testosterone capsule to treat men with certain forms of hypogonadism. An FDA release says that the product is intended for men having low testosterone levels due to specific medical conditions, and should not be used to treat men with “age-related hypogonadism” because benefits do not outweigh its risks for this use. “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,” FDA says.

 

Jatenzo’s efficacy was demonstrated in a four-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, the agency says. Eighty-seven percent of Jatenzo-treated men achieved an average testosterone level within the normal range, which was the primary study endpoint.

 

Jatenzo contains a boxed warning that it can cause blood pressure to rise, increasing the risk of heart attack, stroke and cardiovascular death. “Health care providers should consider a patient’s individual heart disease risks and ensure that blood pressure is adequately controlled before prescribing Jatenzo; they should also periodically monitor patient blood pressure during treatment,” FDA says. “Jatenzo is currently one of two testosterone products that have this boxed warning. The FDA is requiring all testosterone product manufacturers to conduct blood pressure postmarketing trials to more clearly address whether these products increase blood pressure.”

 

Common side effects, occurring in more than 2% of patients in the Jatenzo clinical trial, included headache, an increase in red blood cell count, a decrease in high-density lipoprotein cholesterol, high blood pressure and nausea, the agency says. An increase in prostate specific antigen was also observed.
