Presentations: 535P, 536P, 534P, 104P, 1534P, 444P, 630P, LBA26, 623P, 603P, 593P, 594P, 1309P, 606P, 590P, 826O, 530P, LBA58, 1520O, 48P, 508TiP, 505TiP, 509TiP, 1438TiP

Berlin, September 9, 2021 – Bayer will present new data from its established portfolio of approved oncology therapies at the upcoming ESMO Congress 2021 from September 16-21, 2021. Presentations will center around Bayer’s ongoing focus in addressing patient needs through expanded research with existing therapies in certain cancers as well as studies in new tumor types and in combination with other therapies.

Among the featured research presented will be four distinct analyses for Bayer’s precision oncology treatment Vitrakvi™ (larotrectinib), including updated long-term efficacy and safety findings from an integrated dataset of adult TRK fusion cancer patients. Additional data for larotrectinib include an analysis in adult and pediatric patients according to prior therapy and performance status, as well as an overview on the incidence of fractures in larotrectinib-treated patients. An analysis evaluating larotrectinib compared to entrectinib using a matching-adjusted indirect comparison (MAIC) will also be presented. MAIC is an alternative method for comparative data when a randomized control trial (RCT) is not available and/or possible, like for TRK fusion cancer, which is an ultra-rare disease. Vitrakvi, the first-ever treatment to receive a tumor-agnostic indication at the initial approval in the U.S. and European Union (EU), is approved in more than 40 countries, including most recently in Japan for adult and pediatric patients with solid tumors harboring an NTRK gene fusion. Additional filings in other regions are underway or planned.

New ARAMIS trial data for Nubeqa™ (darolutamide) in patients with non-metastatic castration-resistant prostate cancer (nmCRPC) on the timing of adverse events during the trial will be showcased, continuing to reinforce the established clinical profile of the therapy in this indication.

Additionally, the compound is evaluated in men with metastatic castration-resistant prostate cancer (mCRPC): In the randomized double-blind placebo-controlled phase II trial SAKK 08/16, first data on a maintenance therapy with darolutamide in mCRPC patients previously treated with novel hormonal agents (NHA) and non-progressive disease after subsequent treatment with a taxane will be presented in a late-breaking oral presentation. An analysis from the investigator-initiated ODENZA trial on the cognitive assessment in men with mCRPC randomly receiving darolutamide or enzalutamide will also be presented. Nubeqa is approved in several markets around the world, including the U.S., EU, Japan and China, for the treatment of patients with nmCRPC, who are at high risk of developing metastatic disease. Filings in other regions are underway or planned. The compound is developed jointly by Bayer and Orion Corporation, a globally operating Finnish pharmaceutical company.

Additional data demonstrating the versatility of the prostate cancer treatment Xofigo™ (radium-223 dichloride), the first ever approved Targeted Alpha Therapy, will be presented. Research includes pain efficacy data in patients with mCRPC from the REASSURE and PARABO observational studies. Xofigo is approved in more than 50 countries, including the U.S., EU, China and Japan for patients with mCRPC, symptomatic bone metastases and no known visceral metastases.

Data for Aliqopa™ (copanlisib), the only pan class I phosphatidylinositol-3-kinase (PI3K) inhibitor, include results from a subset of the Phase III trial CHRONOS-3 analyzing copanlisib plus rituximab compared to rituximab and placebo in patients with marginal zone lymphoma (MZL). Copanlisib is currently approved in the U.S., Israel and Taiwan for the treatment of adult patients with relapsed follicular lymphoma (FL) who have received at least two prior systemic therapies. Approvals were based on the overall response rate (ORR) from the open-label, single-arm Phase II CHRONOS-1 (NCT01660451) trial of copanlisib monotherapy in 104 adult patients with follicular B-cell non-Hodgkin’s Lymphoma (NHL) who had relapsed disease following at least two prior systemic therapies. Recently, Bayer has submitted a supplemental new drug application (sNDA) to the U.S. Food and Drug Administration (FDA) in relapsed indolent B-cell NHL and a marketing authorization application (MAA) to the European Medicines Agency (EMA) in relapsed MZL for the novel combination of copanlisib and rituximab. Bayer is in discussions with health authorities worldwide regarding data from CHRONOS-3.

Investigator-initiated research highlighting regorafenib will wrap up Bayer’s presence at the meeting. These investigational data, including a late-breaking abstract on the Phase II REGOBONE study assessing the efficacy and safety of regorafenib in patients with relapsed advanced or metastatic chordoma, and an oral presentation on a collaborative Phase II trial with regorafenib in first-line of KIT/PDGFR wild type advanced gastrointestinal stromal tumors (GIST), continue showcasing regorafenib’s potential in difficult-to-treat tumors. Regorafenib is approved under the brand name Stivarga™ in more than 100 countries for certain types of colorectal cancer, GIST and liver cancer.
