FDA approves first oral drug for treating grownup sufferers with superior prostate most cancers
Today the US Food and Drug Administration approved Orgovyx (Relugolix) for the treatment of adult patients with advanced prostate cancer.
Today’s approval is the first oral drug in its class, and it may eliminate the need for some patients to visit the clinic for treatments that need to be administered by a healthcare provider. This potential to reduce clinic visits can be especially helpful in helping cancer patients stay home and avoid exposure during the coronavirus pandemic. “

The American Cancer Society estimates that there will be more than 190,000 cases of prostate cancer in the United States by 2020. One of the treatment options for advanced prostate cancer is androgen deprivation therapy, which uses drugs to lower the levels of hormones that help prostate cancer cells grow. Current FDA-approved treatments of this type are injected or placed under the skin as small implants. Orgovyx is an orally administered treatment that prevents the pituitary gland from making hormones called luteinizing hormone and follicle stimulating hormone, which reduces the amount of testosterone the testes can make.
The safety and effectiveness of Orgovyx were evaluated in a randomized, open study in men with advanced prostate cancer. Patients were randomly given Orgovyx injections of leuprolide, another hormonally targeted drug, either once a day or every three months for 48 weeks. The aim was to determine whether Orgovyx had achieved and maintained sufficiently low testosterone levels (castrate levels) by day 29 by the end of the course of treatment. The castration rate was 96.7% in the 622 patients who received Orgovyx.
The most common side effects of Orgovyx are: hot flashes, increased glucose, increased triglycerides, musculoskeletal pain, decreased hemoglobin, fatigue, constipation, diarrhea, and increased levels of certain liver enzymes. Simultaneous use of Orgovyx with drugs that inhibit P-glycoprotein, which plays a role in pumping toxins from cells, is contraindicated. Androgen deprivation therapies like Orgovyx can affect the heart’s electrical properties or cause electrolyte imbalances. Therefore, healthcare providers should consider regular monitoring of electrocardiograms and electrolytes.
Based on findings in animals and the mechanism of action, Orgovyx may cause fetal harm and loss of pregnancy when administered to a pregnant woman. It is recommended that men with female partners with reproductive potential use effective contraception during treatment and for two weeks after the last Orgovyx dose. Due to the drug’s suppression of the pituitary-gonadal system, diagnostic test results of the gonadotropic and gonadal functions of the pituitary gland performed during and after taking Orgovyx may be affected.
