U.S. FDA Approves XTANDI® (enzalutamide) after Priority Review for Patients with
Metastatic Castration-Resistant Prostate Cancer Previously Treated with Docetaxel
- Medivation to host conference call today at 11:45am PT -
San Francisco, CA and Tokyo August 31, 2012 Medivation, Inc. (Nasdaq: MDVN) and Astellas Pharma Inc. (TSE: 4503) today announced that the U.S. Food and Drug Administration (FDA) has granted approval to XTANDI® (enzalutamide) capsules for the treatment of patients with metastatic castration-resistant prostate cancer who have previously received docetaxel. XTANDI is an oral, once-daily androgen receptor inhibitor.
The FDA accepted the XTANDI New Drug Application (NDA) on July 23, 2012, and granted the filing Priority Review Designation with a Prescription Drug User Fee Act (PDUFA) action date of November 22, 2012. Medivation and Astellas expect to make XTANDI available to patients in the United States in mid-September 2012, and the specific availability date will be announced on www.XtandiHCP.com as soon as it is known. Separately, a Marketing Authorization Application for XTANDI has been accepted for review by the European Medicines Agency (EMA).
Todays approval marks a significant accomplishment for Medivation. We are proud to be in a position to offer a new treatment, XTANDI, for this patient population for which there is a significant unmet medical need, said David Hung, M.D., co-founder, president and CEO, Medivation, Inc. I would like to extend my thanks to the patients, physicians, and their study teams who participated in the clinical trials, and to our employees, and those of our partner Astellas, who have been instrumental in helping us reach this important milestone.
Enzalutamde provides an exciting new option for physicians that can prolong the lives of patients with metastatic prostate cancer who have received chemotherapy, said Howard I. Scher, M.D., chief, Genitourinary Oncology Service, Sidney Kimmel Center for Prostate and Urologic Cancers, Memorial Sloan-Kettering Cancer Center, and the co-principal investigator of the AFFIRM pivotal study. It is extremely gratifying to have led the clinical trial of enzalutamide, having followed the development of this drug from its early inception in the laboratory to the clinic.
We believe XTANDI has the potential to play an important role in the treatment of advanced prostate cancer, said Stephen Eck, M.D., Ph.D., Vice President of Medical Oncology, Astellas Pharma Global Development. Were eager to work with Medivation to make this much-needed new treatment available to medical professionals and patients in September.
The recommended dose of XTANDI is 160 mg (four 40 mg capsules) administered orally once daily. XTANDI can be taken with or without food and does not require concomitant steroid (e.g., prednisone) use. In the phase 3 clinical trial, 48% of XTANDI patients and 46% of patients in the placebo arm were treated with glucocorticoids.
As a post-marketing requirement, Medivation and Astellas have agreed with the FDA to conduct an open-label safety study of XTANDI (160 mg/day) in patients who are at high risk for seizure. Medivation and Astellas have agreed to provide the data from this study in 2019.
About XTANDI
XTANDI is an androgen receptor inhibitor indicated for the treatment of patients with metastatic castration-resistant prostate cancer (mCRPC) who have previously received docetaxel. The efficacy and safety of XTANDI were assessed in a randomized, placebo-controlled, multicenter phase 3 clinical trial. A total of 1199 patients with mCRPC who had previously received docetaxel were randomized 2:1 to receive either XTANDI orally at a dose of 160 mg once daily (N = 800) or placebo (N = 399). Patients with a history of seizure, taking medications known to decrease the seizure threshold, or with other risk factors for seizure were excluded from the clinical trial. The primary endpoint of the trial was overall survival.
XTANDI-treated patients had a statistically-significant improvement in median overall survival compared to the placebo group: 18.4 months in the XTANDI group versus 13.6 months in the placebo group (P<0.0001). XTANDI provided a 37% reduction in risk of death compared to placebo (hazard ratio = 0.631). Seizure occurred in 0.9% of patients on XTANDI and 0% of the placebo-treated patients. The most common adverse reactions (³5%) are asthenia/fatigue, back pain, diarrhea, arthralgia, hot flush, peripheral edema, musculoskeletal pain, headache, upper respiratory infection, muscular weakness, dizziness, insomnia, lower respiratory infection, spinal cord compression and cauda equina syndrome, hematuria, paresthesia, anxiety, and hypertension. Grade 3 and higher adverse reactions were reported among 47% of XTANDI-treated patients and 53% of placebo-treated patients.
XTANDI Mechanism of Action
XTANDI (enzalutamide) is an androgen receptor inhibitor that acts on different steps in the androgen receptor signaling pathway. XTANDI has been shown to competitively inhibit androgen binding to androgen receptors and inhibit androgen receptor nuclear translocation and interaction with DNA. A major metabolite, N-desmethyl enzalutamide, exhibited similar in vitro activity to XTANDI. XTANDI decreased proliferation and induced cell death of prostate cancer cells in vitro, and decreased tumor volume in a mouse prostate cancer xenograft model.
Important Safety Information for XTANDI
Contraindications- XTANDI can cause fetal harm when administered to a pregnant woman based on its mechanism of action. XTANDI is not indicated for use in women. XTANDI is contraindicated in women who are or may become pregnant.
Warning and Precautions- In the randomized clinical trial, seizure occurred in 0.9% of patients on XTANDI. No patients on the placebo arm experienced seizure. Patients experiencing a seizure were permanently discontinued from therapy. All seizures resolved. Patients with a history of seizure, taking medications known to decrease the seizure threshold, or with other risk factors for seizure were excluded from the clinical trial. Because of the risk of seizure associated with XTANDI use, patients should be advised of the risk of engaging in any activity where sudden loss of consciousness could cause serious harm to themselves or others.
Adverse Reactions- The most common adverse drug reactions (³5%) reported in patients receiving XTANDI in the randomized clinical trial were asthenia/fatigue, back pain, diarrhea, arthralgia, hot flush, peripheral edema, musculoskeletal pain, headache, upper respiratory infection, muscular weakness, dizziness, insomnia, lower respiratory infection, spinal cord compression and cauda equina syndrome, hematuria, paresthesia, anxiety, and hypertension.
Drug Interactions- Enzalutamide is a strong CYP3A4 inducer and a moderate CYP2C9 and CYP2C19 inducer in humans. Administration of strong CYP2C8 inhibitors can increase the plasma exposure to XTANDI. Co-administration of XTANDI with strong CYP2C8 inhibitors should be avoided if possible. If co-administration of XTANDI cannot be avoided, reduce the dose of XTANDI. Co-administration of XTANDI with strong CYP3A4 and CYP2C8 inducers may decrease the plasma exposure of XTANDI and should be avoided if possible. Avoid CYP3A4, CYP2C9 and CYP2C19 substrates with a narrow therapeutic index, as XTANDI may decrease the plasma exposures of these drugs. If XTANDI is co-administered with warfarin (CYP2C9 substrate), conduct additional INR monitoring.
