Berlin, April 11, 2023 – Bayer will present latest research across its oncology portfolio at the American Association for Cancer Research (AACR) 2023 Annual Meeting, taking place from April 14-19 in Orlando (FL), USA. Bayer is advancing its oncology R&D efforts in three scientific areas that have the potential to address unmet needs in cancer patients: next-generation Immuno-Oncology, Targeted Radionuclide Therapies and Precision Molecular Oncology. Data from all three areas of scientific focus will be showcased during this year’s meeting.
Bayer is progressing novel research around its prostate cancer treatment darolutamide. The presentation highlights the synergistic anti-cancer effects of a PSMA (prostate-specific membrane antigen)-actinium-225 conjugatePSMA (prostate-specific membrane antigen)-actinium-225 conjugate in combination with darolutamide in preclinical prostate cancer models. Darolutamide, which is jointly developed by Bayer and Orion Corporation, is an oral androgen receptor inhibitorandrogen receptor inhibitor indicated for the treatment of men with non-metastatic castration-resistant prostate cancer (nmCRPC), who are at high risk of developing metastatic disease and for the treatment of men with metastatic hormone-sensitive prostate cancer (mHSPC).
Bayer will present the first clinical Phase 1 results on aryl hydrocarbon receptor (AhR) inhibitor BAY 2416964, the company’s most advanced Immuno-Oncology program. A focus of the presentation will be on the target engagement results and pharmacokinetics from its ongoing monotherapy dose-escalation study to explore a potential optimal dose and schedule to effectively inhibit AhR. These results, along with a mathematical model-informed approach have supported the currently ongoing dose expansion for BAY 2416964.
In the New Drugs on the Horizon session at AACR, Bayer will present preclinical data on its novel selective diacylglycerol kinase (DGK) zeta inhibitor BAY 2965501diacylglycerol kinase (DGK) zeta inhibitor BAY 2965501, which is under Phase 1 clinical evaluation. The enzyme DGKzeta is a lipid kinase that can down-modulate T-cell activation by catalyzing the conversion of diacylglycerol to phosphatidic acid, thus acting as a ligand-independent, intracellular immune checkpoint. An inhibition of DGKzeta has been demonstrated to enhance T-cell priming against suboptimal tumor antigens and has the potential to overcome multiple immune-suppressive mechanisms in the tumor microenvironment. Based on these data, a first-in-human trial with BAY 2965501 in patients with advanced solid tumors was initiated and is currently enrolling patients.
Both small molecule inhibitors in Immuno-Oncology are being jointly developed in a strategic research alliance with the German Cancer Research Center (DKFZ)Cancer Research Center (DKFZ) in Heidelberg, Germany.
From its focus area Precision Molecular Oncology, Bayer will show new preclinical data on its mutEGFR/HER2 inhibitormutEGFR/HER2 inhibitor, which was developed in collaboration with the Broad Institute of MIT and Harvard in Cambridge (MA), USA. BAY 2927088 is a reversible small molecule inhibitor that is currently being evaluated in a first-in-human, Phase 1 clinical trial in non-small cell lung cancer (NSCLC) patients with mutations in epidermal growth factor receptors (EGFR & HER2) including exon20 insertions and point mutations. For the first time, Bayer will present the design of the clinical trial and the preclinical activity profile of the inhibitor in human epidermal growth factor receptor 2 (HER2) mutant NSCLChuman epidermal growth factor receptor 2 (HER2) mutant NSCLC.
Bayer will also report new data looking at larotrectinib, a highly selective and central nervous system (CNS)-active tropomyosin receptor kinase (TRK) inhibitor, approved for the treatment of patients with TRK fusion solid tumors, exploring the concordance between tissue and circulating tumor DNA (ctDNA) testing for neurotrophic tyrosine receptor kinase (NTRK) gene fusions from samples in larotrectinib clinical trials.
Additional research to be presented from Bayer’s Targeted Alpha Therapy program evaluates the antitumor efficacy and potential benefit of the combination of radium-223 with 177Lu-PSMA-617 in a preclinical model of bone metastatic prostate cancer. The combination of radium-223 and 177Lu PSMA imaging and therapy (I&T) is currently being investigated in patients with metastatic castration-resistant prostate cancer (mCRPC) in a phase 1/2 trial (AlphaBet, NCT05383079).
