WHIPPANY, N.J.–(BUSINESS WIRE)–Bayer announced today data from the Company’s evolving oncology portfolio will be presented at the 2020 American Society of Clinical Oncology Genitourinary (ASCO GU) Cancers Symposium, taking place February 13-15, 2020 in San Francisco, California. The presentations across the latest research for Bayer’s marketed and pipeline therapies highlight the company’s ongoing commitment to exploring the potential of its therapies across different indications and treatment settings.

New data on the effect of Nubeqa® (darolutamide) on cerebral blood flow compared to enzalutamide in men with non-metastatic castration-resistant prostate cancer (nmCRPC) will be presented. Nubeqa, an androgen receptor inhibitor (ARi) jointly developed by Bayer and Orion Corporation, is approved in the U.S., Japan and Brazil, and recently received a positive CHMP opinion in the European Union (EU).

The research presented from Bayer’s prostate cancer portfolio will also include several presentations that feature real-world and combination studies with Xofigo® (radium Ra 223 dichloride) in men with certain types of prostate cancer. Among these is the first presentation of investigational data from a randomized Phase II study of sipuleucel-T (SipT) with or without Xofigo in men with asymptomatic metastatic castration-resistant prostate cancer (mCRPC).

Notable presentations at ASCO GU 2020 are listed below:

Darolutamide

Radium Ra 223 Dichloride (radium-223)

About NUBEQA® (darolutamide)1

NUBEQA is an androgen receptor inhibitor (ARi) with a distinct chemical structure that competitively inhibits androgen binding, AR nuclear translocation, and AR-mediated transcription.1 A Phase III study in metastatic hormone-sensitive prostate cancer (ARASENS) is ongoing. Information about this trial can be found at www.clinicaltrials.gov.

On July 30th, 2019, the FDA approved NUBEQA® (darolutamide) based on the ARAMIS trial, a randomized, double-blind, placebo-controlled, multi-center Phase III study, which evaluated the safety and efficacy of oral NUBEQA in patients with nmCRPC who were receiving a concomitant gonadotropin-releasing hormone (GnRH) analog or had a bilateral orchiectomy. In the clinical study, 1,509 patients were randomized in a 2:1 ratio to receive 600 mg of NUBEQA orally twice daily or placebo plus ADT. The primary efficacy endpoint was MFS, defined as the time from randomization to the time of first evidence of blinded independent central review (BICR)-confirmed distant metastasis or death due to any cause within 33 weeks after the last evaluable scan, whichever occurred first. NUBEQA plus ADT demonstrated a statistically significant improvement in MFS, with a median MFS of 40.4 months [95% CI (34.3, NR), p<0.0001] versus 18.4 months [95% CI (15.5, 22.3), p<0.0001] with placebo plus ADT [HR=0.41, 95% CI (0.34, 0.50), p<0.0001].

Adverse reactions occurring more frequently in the NUBEQA arm (≥2 % over placebo) were fatigue (16% versus 11%), pain in extremity (6% versus 3%) and rash (3% versus 1%). NUBEQA was not studied in women and there is a warning and precaution for embryo-fetal toxicity.

Overall survival (OS) data were not mature at the time of final MFS analysis (57% of the required number of events). The planned final analysis has been conducted and mature data on OS and other secondary endpoints will be presented at an upcoming scientific meeting.

INDICATION for NUBEQA (darolutamide)

NUBEQA is approved for the treatment of patients with non-metastatic castration-resistant prostate cancer (nmCRPC).1

IMPORTANT SAFETY INFORMATION for NUBEQA (darolutamide)

Embryo-Fetal Toxicity: Safety and efficacy of NUBEQA have not been established in females. NUBEQA can cause fetal harm and loss of pregnancy. Advise males with female partners of reproductive potential to use effective contraception during treatment with NUBEQA and for 1 week after the last dose.

Adverse Reactions

Adverse reactions occurring more frequently in the NUBEQA arm (≥2% over placebo) were fatigue (16% vs. 11%), pain in extremity (6% vs. 3%) and rash (3% vs. 1%). Serious adverse reactions occurred in 25% of patients receiving NUBEQA and in 20% of patients receiving placebo. Serious adverse reactions in ≥ 1 % of patients who received NUBEQA were urinary retention, pneumonia, and hematuria. Overall, 3.9% of patients receiving NUBEQA and 3.2% of patients receiving placebo died from adverse reactions, which included death (0.4%), cardiac failure (0.3%), cardiac arrest (0.2%), general physical health deterioration (0.2%), and pulmonary embolism (0.2%) for NUBEQA. Clinically significant adverse reactions occurring in ≥ 2% of patients treated with NUBEQA included ischemic heart disease (4.0% vs. 3.4% on placebo) and heart failure (2.1% vs. 0.9% on placebo).

Drug Interactions

Effect of Other Drugs on NUBEQA –Concomitant use of NUBEQA with a combined P-gp and strong or moderate CYP3A4 inducer decreases darolutamide exposure, which may decrease NUBEQA activity. Avoid concomitant use of NUBEQA with combined P-gp and strong or moderate CYP3A4 inducers.

Concomitant use of NUBEQA with a combined P-gp and strong CYP3A4 inhibitor increases darolutamide exposure, which may increase the risk of NUBEQA adverse reactions. Monitor patients more frequently for NUBEQA adverse reactions and modify NUBEQA dosage as needed.

Effects of NUBEQA on Other Drugs –NUBEQA is an inhibitor of breast cancer resistance protein (BCRP) transporter. Concomitant use of NUBEQA increases the exposure (AUC) and maximal concentration of BCRP substrates, which may increase the risk of BCRP substrate-related toxicities. Avoid concomitant use with drugs that are BCRP substrates where possible. If used together, monitor patients more frequently for adverse reactions, and consider dose reduction of the BCRP substrate drug. Consult the approved product labeling of the BCRP substrate when used concomitantly with NUBEQA.

For important risk and use information about NUBEQA, please see the accompanying full Prescribing Information.

About Xofigo® (radium Ra 223 dichloride) Injection2

Xofigo is indicated for the treatment of patients with castration-resistant prostate cancer, symptomatic bone metastases and no known visceral metastatic disease.

Important Safety Information for Xofigo® (radium Ra 223 dichloride) Injection

Warnings and Precautions:

Administration and Radiation Protection: Xofigo should be received, used, and administered only by authorized persons in designated clinical settings. The administration of Xofigo is associated with potential risks to other persons from radiation or contamination from spills of bodily fluids such as urine, feces, or vomit. Therefore, radiation protection precautions must be taken in accordance with national and local regulations

Fluid Status: Dehydration occurred in 3% of patients on Xofigo and 1% of patients on placebo. Xofigo increases adverse reactions such as diarrhea, nausea, and vomiting, which may result in dehydration. Monitor patients’ oral intake and fluid status carefully and promptly treat patients who display signs or symptoms of dehydration or hypovolemia

Injection Site Reactions: Erythema, pain, and edema at the injection site were reported in 1% of patients on Xofigo

Secondary Malignant Neoplasms: Xofigo contributes to a patient’s overall long-term cumulative radiation exposure. Long-term cumulative radiation exposure may be associated with an increased risk of cancer and hereditary defects. Due to its mechanism of action and neoplastic changes, including osteosarcomas, in rats following administration of radium-223 dichloride, Xofigo may increase the risk of osteosarcoma or other secondary malignant neoplasms. However, the overall incidence of new malignancies in the randomized trial was lower on the Xofigo arm compared to placebo (<1% vs 2%; respectively), but the expected latency period for the development of secondary malignancies exceeds the duration of follow-up for patients on the trial

Subsequent Treatment With Cytotoxic Chemotherapy: In the randomized clinical trial, 16% of patients in the Xofigo group and 18% of patients in the placebo group received cytotoxic chemotherapy after completion of study treatments. Adequate safety monitoring and laboratory testing was not performed to assess how patients treated with Xofigo will tolerate subsequent cytotoxic chemotherapy

Adverse Reactions: The most common adverse reactions (≥10%) in the Xofigo arm vs the placebo arm, respectively, were nausea (36% vs 35%), diarrhea (25% vs 15%), vomiting (19% vs 14%), and peripheral edema (13% vs 10%). Grade 3 and 4 adverse events were reported in 57% of Xofigo-treated patients and 63% of placebo-treated patients. The most common hematologic laboratory abnormalities in the Xofigo arm (≥10%) vs the placebo arm, respectively, were anemia (93% vs 88%), lymphocytopenia (72% vs 53%), leukopenia (35% vs 10%), thrombocytopenia (31% vs 22%), and neutropenia (18% vs 5%)
