The oral presentation (Abstract: 2521) highlights safety and preliminary efficacy data from a clinical study (NCT03486301) of EIK1001, a Toll-like receptor 7/8 (TLR7/8) co-agonist, in combination with pembrolizumab in participants with advanced solid tumors. The new data show that EIK1001 was well-tolerated with a manageable safety profile, and showed encouraging preliminary efficacy across several tumor types in combination with pembrolizumab. Responses were observed even in heavily pretreated patients not anticipated to respond to pembrolizumab monotherapy. Anthony W. Tolcher, MD, FASCO, of New Experimental Therapeutics (NEXT), will deliver the presentation on June 2, 2024 at 12:42 PM CDT.

"We are encouraged by the promising data emerging from our lead clinical programs," said Roy D. Baynes, MB.BCh., Ph.D., Chief Medical Officer of Eikon Therapeutics. "The safety and preliminary efficacy results for EIK1001, in combination with pembrolizumab and with atezolizumab, underscore the potential of these promising approaches. We highlight also the advancement of EIK1001 into front-line combinations with standard-of-care pembrolizumab and chemotherapy in non-small cell lung cancer, and of our PARP1-selective inhibitor, EIK1003, into phase 1 studies in cancers selected for specific genotypes."

In addition, three posters will be presented and include:
