—Intended for U.S. Media Only–

WHIPPANY, N.J.–(BUSINESS WIRE)–Bayer will present new data across its oncology portfolio at the 2022 American Society of Clinical Oncology (ASCO) Annual Meeting from June 3-7, 2022. These presentations continue to reinforce Bayer’s position as an innovator in oncology and ongoing dedication to advancing oncology treatments for patients on a global scale.

NUBEQA® (darolutamide) data presented will include overall survival (OS) and prostate-specific antigen (PSA) results from the investigational Phase III ARASENS trial in metastatic hormone-sensitive prostate cancer (mHSPC) and results of a post-hoc analysis from the Phase III ARAMIS trial in non-metastatic castration-resistant prostate cancer (nmCRPC). NUBEQA is an androgen receptor inhibitor (ARi) with a distinct chemical structure that competitively inhibits androgen binding, AR nuclear translocation, and AR-mediated transcription. NUBEQA is indicated in the U.S. for the treatment of men with nmCRPC.1 The U.S. Food and Drug Administration (FDA) has recently accepted a supplemental New Drug Application (sNDA) and granted Priority Review for NUBEQA in combination with docetaxel for the treatment of mHSPC.

Research on Xofigo® (radium Ra 223 dichloride) will also be highlighted, including results from an interim analysis of the RALU study, which evaluated safety and survival outcomes in patients with metastatic castration-resistant prostate cancer (mCRPC) treated with lutetium-177-prostate-specific membrane antigen (177Lu-PSMA) after Xofigo. Additionally, alkaline phosphatase (ALP) decline and OS data in mCRPC patients treated with Xofigo in the REASSURE study will be presented. Xofigo is indicated for the treatment of patients with mCRPC, symptomatic bone metastases, and no known visceral metastatic disease.2

Efficacy and safety findings of Vitrakvi® (larotrectinib) for patients with TRK fusion cancer from an integrated pooled analysis per an independent review committee (IRC) assessment, efficacy and safety data from an expanded dataset, updated health-related quality of life (QoL) of adult and pediatric patients with TRK fusion cancer, and sub-analyses for TRK fusion cancer patients with primary central nervous system (CNS) tumors and lung cancer, respectively, will be shared. Additional data for Vitrakvi include an analysis in adult and pediatric patients evaluating Vitrakvi compared to standard of care using a matching-adjusted indirect comparison (MAIC). MAIC is an alternative method for comparative data when a randomized control trial (RCT) is not available and/or possible, as for a rare condition like TRK fusion cancer.3 Results from these studies further support Vitrakvi’s existing clinical profile in TRK fusion cancer across a variety of tumor types and ages. Vitrakvi is approved for the treatment of adult and pediatric patients with solid tumors that have a NTRK gene fusion without a known acquired resistance mutation, are metastatic or where surgical resection is likely to result in severe morbidity, and have no satisfactory alternative treatments or that have progressed following treatment. Patients should be selected for therapy based on a Food and Drug Administration (FDA)-approved test. This indication is approved under accelerated approval based on overall response rate (ORR) and duration of response. Continued approval for this indication may be contingent upon verification and description of clinical benefit in confirmatory trials.4

Other research includes investigator-initiated research (IIR) for Stivarga® (regorafenib) and Nexavar® (sorafenib) in several areas of oncology.

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

On July 30, 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 non-metastatic castration-resistant prostate cancer (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 in combination with androgen deprivation therapy (ADT) or ADT alone. The primary efficacy endpoint was metastasis-free survival (MFS). NUBEQA is also being investigated in further studies across various stages of prostate cancer, including in the ARANOTE Phase III trial evaluating NUBEQA plus ADT versus ADT alone for metastatic hormone-sensitive prostate cancer (mHSPC), as well as in the Australian and New Zealand Urogenital and Prostate Cancer Trials Group (ANZUP) led international Phase III co-operative group DASL-HiCaP (ANZUP1801) trial evaluating NUBEQA as an adjuvant treatment for localized prostate cancer with very high risk of recurrence. Information about these trials can be found at www.clinicaltrials.gov.

Developed jointly by Bayer and Orion Corporation, a globally operating Finnish pharmaceutical company, NUBEQA is indicated for the treatment of men with nmCRPC.1 The approvals of NUBEQA for nmCRPC in the U.S., European Union (EU), and other global markets have been based on the pivotal Phase III ARAMIS trial data evaluating the efficacy and safety of NUBEQA plus ADT compared to ADT alone.1 Filings in other regions are underway or planned.

INDICATION FOR NUBEQA® (darolutamide)

NUBEQA® (darolutamide) is an androgen receptor inhibitor indicated for the treatment of patients with non-metastatic castration-resistant prostate cancer.

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

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.

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%).

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 – Combined P-gp and strong or moderate CYP3A4 inducers decrease NUBEQA exposure, which may decrease NUBEQA activity. Avoid concomitant use.

Combined P-gp and strong CYP3A4 inhibitors increase NUBEQA exposure, which may increase the risk of NUBEQA adverse reactions. Monitor more frequently and modify NUBEQA dose as needed.

Effects of NUBEQA on Other Drugs – NUBEQA inhibits breast cancer resistance protein (BCRP) transporter. Concomitant use increases exposure (AUC) and maximal concentration of BCRP substrates, which may increase the risk of BCRP substrate-related toxicities. Avoid concomitant use where possible. If used together, monitor more frequently for adverse reactions, and consider dose reduction of the BCRP substrate.

NUBEQA inhibits OATP1B1 and OATP1B3 transporters. Concomitant use may increase plasma concentrations of OATP1B1 or OATP1B3 substrates. Monitor more frequently for adverse reactions and consider dose reduction of these substrates.

Review the prescribing information of drugs that are BCRP, OATP1B1, and OATP1B3 substrates 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%)

Please see the full Prescribing Information for Xofigo (radium Ra 223 dichloride).
