Orgovyx Drug Information

is indicated for the treatment of adult patients with advanced prostate cancer. ORGOVYX is a gonadotropin-releasing hormone (GnRH) receptor antagonist indicated for the treatment of adult patients with advanced prostate cancer.

Recommended Dosage Initiate treatment of

ORGOVYX with a loading dose of 360 mg on the first day and continue treatment with a 120 mg dose taken orally once daily at approximately the same time each day. ORGOVYX can be taken with or without food . Instruct patients to swallow tablets whole and not to crush or chew tablets. Advise patients to take a missed dose of ORGOVYX as soon as they remember.

If the dose was missed by more than 12 hours, patients should not take the missed dose and resume with the next scheduled dose. If treatment with ORGOVYX is interrupted for greater than 7 days, restart ORGOVYX with a loading dose of 360 mg on the first day, and continue with a dose of 120 mg once daily. In patients treated with GnRH receptor agonists and antagonists for prostate cancer, treatment is usually continued upon development of nonmetastatic or metastatic castration-resistant prostate cancer.

Dosage Modifications for P-gp Inhibitors

Avoid co-administration of ORGOVYX with oral P-gp inhibitors. If co-administration is unavoidable, take ORGOVYX first and separate dosing by at least 6 hours . Monitor patients for increased adverse reactions. Treatment with ORGOVYX may be interrupted for up to two weeks if a short course of treatment with a P-gp inhibitor is required.

Resume ORGOVYX after the P-gp inhibitor is discontinued. If treatment with ORGOVYX is interrupted for greater than 7 days, restart ORGOVYX with a loading dose of 360 mg on the first day and continue with a dose of 120 mg once daily.

Dosage Modifications for Combined P-gp and Strong

CYP3A Inducers 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 .

Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The safety of ORGOVYX was evaluated in HERO, a randomized (2:1), open-label, clinical study in patients with advanced prostate cancer . Patients received orally administered ORGOVYX as a loading dose of 360 mg on the first day followed by 120 mg taken orally once daily (n = 622) or received leuprolide acetate administered by depot injection at doses of 22.5 mg (n = 264) or 11.25 mg (n = 44) per local guidelines every 12 weeks (n = 308). Leuprolide acetate 11.25 mg is a dosing regimen that is not recommended for this indication in the US. Among patients who received ORGOVYX, 91% were exposed for at least 48 weeks. Ninety-nine (16%) patients received concomitant radiotherapy and 17 (3%) patients received concomitant enzalutamide with ORGOVYX. 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. Permanent discontinuation of ORGOVYX due to an 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%). 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%). The most common adverse reactions (≥ 10%) and laboratory abnormalities (≥ 15%) were hot flush (54%), glucose increased (44%), triglycerides increased (35%), musculoskeletal pain (30%), hemoglobin decreased (28%), alanine aminotransferase increased (ALT) (27%), fatigue (26%), aspartate aminotransferase increased (AST) (18%), constipation (12%), and diarrhea (12%). Table 1 summarizes the adverse reactions in HERO. Table 1: Adverse Reactions ( ≥ 10%) of Patients with Advanced Prostate Cancer Who Received ORGOVYX in HERO a Includes arthralgia, back pain, pain in extremity, musculoskeletal pain, myalgia, bone pain, neck pain, arthritis, musculoskeletal stiffness, non-cardiac chest pain, musculoskeletal chest pain, spinal pain, and musculoskeletal discomfort. b Includes fatigue and asthenia. c Includes diarrhea and colitis.

The following adverse reactions have been identified during post-approval use of ORGOVYX. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Immune system disorders: hypersensitivity, including angioedema and urticaria.

Effect of Other Drugs on

ORGOVYX P-gp Inhibitors Relugolix is a P-gp substrate. Co-administration of ORGOVYX with an oral P-gp inhibitor increases relugolix exposure, which may increase the risk of adverse reactions associated with ORGOVYX. Avoid co-administration of ORGOVYX with oral P-gp inhibitors. If co-administration with an oral P-gp inhibitor cannot be avoided, take ORGOVYX first and separate dosing by at least 6 hours.

Monitor patients for increased adverse reactions . Treatment with ORGOVYX may be interrupted for up to two weeks if a short course of treatment with a P-gp inhibitor is required. Resume ORGOVYX after the P-gp inhibitor is discontinued. If treatment with ORGOVYX is interrupted for greater than 7 days, restart ORGOVYX with a loading dose of 360 mg on the first day and continue with a dose of 120 mg once daily.

Combined P-gp and Strong CYP3A Inducers Relugolix is a P-gp and CYP3A substrate. Co-administration of ORGOVYX with a combined P-gp and strong CYP3A inducer decreases relugolix exposure, which may reduce the effects of ORGOVYX. Avoid co-administration of ORGOVYX with combined P-gp and strong CYP3A inducers. If co-administration cannot be avoided, increase the ORGOVYX dose.

After discontinuation of the combined P-gp and strong CYP3A inducer, resume ORGOVYX once daily at the same dose .

Pregnancy Risk Summary 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 . There are no human data on the use of ORGOVYX in pregnant females to inform the drug-associated risk. In an animal reproduction study, oral administration of relugolix to pregnant rabbits during organogenesis caused embryo-fetal lethality at maternal exposures that were 0.3 times the human exposure at the recommended dose of 120 mg daily based on AUC ( see Data ). Advise patients of the potential risk to the fetus.

Data Animal Data In an embryo-fetal development study, oral administration of relugolix to pregnant rabbits during the period of organogenesis resulted in abortion, total litter loss, or decreased number of live fetuses at a dose of 9 mg/kg/day (approximately 0.3 times the human exposure at the recommended dose of 120 mg daily based on AUC).

Pediatric Use The safety and efficacy of ORGOVYX in pediatric patients have not been established.

is contraindicated in patients with severe hypersensitivity to relugolix or to any of the product components. Known severe hypersensitivity to relugolix or to any of the product components.
