ORGOVYX is an oral, gonadotropin-releasing hormone (GnRH) receptor antagonist indicated for the treatment of adult patients with advanced prostate cancer.1
ORGOVYX is a nonpeptide GnRH receptor antagonist that competitively binds to pituitary GnRH receptors, thereby directly reducing the release of luteinizing hormone (LH) and follicle-stimulating hormone (FSH), and consequently testosterone. The mechanism of action of ORGOVYX does not cause an initial testosterone surge and therefore helps avoid potential tumor flare.1,2 Learn more about ORGOVYX’s Mechanism of Action.

ORGOVYX is the only oral, once-a-day gonadotropin-releasing hormone (GnRH) receptor antagonist to treat adult patients with advanced prostate cancer. It should be initiated with a loading dose of 360 mg on the first day. Treatment should continue with a 120 mg dose taken orally once a day at approximately the same time each day.1

ORGOVYX can be taken with or without food. Tablets should be swallowed whole and should not be crushed or chewed.1 Learn more.

In the HERO study, patients were excluded who had previously received a GnRH analog or other form of androgen deprivation therapy (estrogen or antiandrogen) for greater than 18 months’ total duration. If androgen deprivation therapy was received for less than or equal to 18 months’ total duration, then that androgen deprivation therapy must have been completed at least 3 months prior to the start of the HERO trial. If the dosing interval of the androgen deprivation therapy depot was longer than 3 months, the prior androgen deprivation therapy must have been completed at least as long as the dosing interval of that depot.2
The HERO study was a multinational, randomized, open-label, phase 3 study in 934* men with advanced prostate cancer. Patients were randomized 2:1 to receive ORGOVYX (360 mg on the first day followed by daily doses of 120 mg orally [n=622]) or leuprolide acetate (22.5 mg injection [or 11.25 mg in Japan and Taiwan per local guidelines] subcutaneously every 3 months [n=308]) for 48 weeks.1,2 View key inclusion and exclusion criteria for the HERO study design on this website.

*Two patients in each arm did not receive the study treatment and were not included.1

11.25 mg is a dosage regimen that is not recommended for advanced prostate cancer in the United States.1

The primary endpoint of the HERO study was sustained testosterone suppression rate (defined as the cumulative probability of testosterone suppression to <50 ng/dL while on study treatment from Day 29 through Week 48).1,2 View the study design.
  • In the HERO study, 96.7% of men treated with ORGOVYX achieved sustained testosterone suppression to <50 ng/dL from Day 29 through Week 481
    • 88.8% of men treated with leuprolide sustained testosterone suppression from Day 29 through Week 481
  • In the HERO study, on Day 4, 56% of men treated with ORGOVYX achieved testosterone suppression to <50 ng/dL1*
    • 0% of men treated with leuprolide had testosterone levels <50 ng/dL on Day 41
  • In the HERO study, on Day 15, 99% of men treated with ORGOVYX achieved testosterone suppression to <50 ng/dL1*
    • 12% of men treated with leuprolide had testosterone levels <50 ng/dL on Day 151
  • In the HERO study, on Day 15, 78% of men treated with ORGOVYX achieved profound testosterone suppression defined as testosterone levels <20 ng/dL1*
    • 1% of men treated with leuprolide had testosterone levels <20 ng/dL on Day 151
  • In the HERO study, on Day 29, 95% of men treated with ORGOVYX achieved profound testosterone suppression defined as testosterone levels <20 ng/dL1*
    • 57% of men treated with leuprolide had testosterone levels <20 ng/dL on Day 291

QT/QTc Interval Prolongation: Androgen deprivation therapy, such as ORGOVYX may prolong the QT/QTc interval. Providers should consider whether the benefits of androgen deprivation therapy outweigh the potential risks in patients with congenital long QT syndrome, congestive heart failure, or frequent electrolyte abnormalities and in patients taking drugs known to prolong the QT interval. Electrolyte abnormalities should be corrected. Consider periodic monitoring of electrocardiograms and electrolytes.

Embryo-Fetal Toxicity: The safety and efficacy of ORGOVYX have not been established in females. Based on findings in animals and mechanism of action, ORGOVYX can cause fetal harm and loss of pregnancy when administered to a pregnant female. Advise males with female partners of reproductive potential to use effective contraception during treatment and for 2 weeks after the last dose of ORGOVYX.

Laboratory Testing: Therapy with ORGOVYX results in suppression of the pituitary gonadal system. Results of diagnostic tests of the pituitary gonadotropic and gonadal functions conducted during and after ORGOVYX may be affected. The therapeutic effect of ORGOVYX should be monitored by measuring serum concentrations of prostate-specific antigen (PSA) periodically. If PSA increases, serum concentrations of testosterone should be measured.

In the HERO study, serious adverse reactions occurred in 12% of patients receiving ORGOVYX. Serious adverse reactions in ≥0.5% of patients included myocardial infarction (0.8%), acute kidney injury (0.6%), arrhythmia (0.6%), hemorrhage (0.6%), and urinary tract infection (0.5%). Fatal adverse reactions occurred in 0.8% of patients receiving ORGOVYX, including metastatic lung cancer (0.3%), myocardial infarction (0.3%), and acute kidney injury (0.2%). Fatal and non-fatal myocardial infarction and stroke were reported in 2.7% of patients receiving ORGOVYX. Learn more about serious adverse reactions in the HERO study.

Permanent discontinuation of ORGOVYX due to adverse reaction occurred in 3.5% of patients. Adverse reactions which resulted in permanent discontinuation of ORGOVYX in ≥0.3% of patients included atrioventricular block (0.3%), cardiac failure (0.3%), hemorrhage (0.3%), increased transaminases (0.3%), abdominal pain (0.3%), and pneumonia (0.3%).1

Dosage interruptions of ORGOVYX due to an adverse reaction occurred in 2.7% of patients. Adverse reactions which required dosage interruption in ≥0.3% of patients included fracture (0.3%).1

Most common adverse reactions (≥10%) and laboratory abnormalities (≥15%) in patients receiving ORGOVYX were hot flush (54%), glucose increased (44%), triglycerides increased (35%), musculoskeletal pain (30%), hemoglobin decreased (28%), alanine aminotransferase increased (27%), fatigue (26%), aspartate aminotransferase increased (18%), constipation (12%), and diarrhea (12%).1 Learn more about AEs in the HERO study.

Clinically relevant adverse reactions in <10% of patients who received ORGOVYX included increased weight, insomnia, gynecomastia, hyperhidrosis, depression, and decreased libido.1

In the HERO study, 622 patients received oral ORGOVYX. Among those, 16% (99/622) of patients received concomitant radiotherapy and 3% (17/622) of patients received concomitant enzalutamide with ORGOVYX.1

Avoid coadministration of ORGOVYX with oral P-gp inhibitors. If coadministration is unavoidable, take ORGOVYX first and separate dosing by at least 6 hours. Treatment with ORGOVYX may be interrupted for up to 2 weeks if a short course of treatment with a P-gp inhibitor is required.1

Avoid coadministration of ORGOVYX with combined P-gp and strong CYP3A inducers. If co-administration is unavoidable, increase the ORGOVYX dose to 240 mg once daily. After discontinuation of the combined P-gp and strong CYP3A inducer, resume the recommended ORGOVYX dose of 120 mg once daily.1

Please see the full Prescribing Information for potential drug interactions.

Drug Interactions

Co-administration of ORGOVYX with a P-gp inhibitor increases the area under the curve (AUC) and maximum concentration (Cmax) of ORGOVYX, which may increase the risk of adverse reactions associated with ORGOVYX. Avoid co-administration of ORGOVYX with oral P-gp inhibitors. If co-administration is unavoidable, take ORGOVYX first, separate dosing by at least 6 hours, and monitor patients more frequently for adverse reactions. Treatment with ORGOVYX may be interrupted for up to 2 weeks for a short course of treatment with certain P-gp inhibitors. If treatment with ORGOVYX is interrupted for more than 7 days, resume administration of ORGOVYX with a 360 mg loading dose on the first day, followed by 120 mg once daily.

Co-administration of ORGOVYX with a combined P-gp and strong CYP3A inducer decreases the AUC and Cmax of ORGOVYX, which may reduce the effects of ORGOVYX. Avoid co-administration of ORGOVYX with combined P-gp and strong CYP3A inducers. If co-administration is unavoidable, increase the ORGOVYX dose to 240 mg once daily. After discontinuation of the combined P-gp and strong CYP3A inducer, resume the recommended ORGOVYX dose of 120 mg once daily.

INDICATION
