Context Therapeutics Reports Third Quarter 2023 Operating and Financial Results - "Research and development (“R&D”) expenses were $4.5 million for the third quarter 2023, as compared to $2.1 million for the same period in 2022. The increase in R&D expenses was driven by higher CTIM-76 contract manufacturing costs and preclinical costs as a result of ongoing IND-enabling studies and activities. This increase was partially offset by a decrease in onapristone extended release (“ONA-XR”) expenses, primarily due to the Company’s decision in March 2023 to discontinue the development of ONA-XR and focus on the development of CTIM-76."

Context Therapeutics Reports Third Quarter 2023 Operating and Financial Results - "In November 2023, announced encouraging preclinical data presented at the SITC 38th Annual Meeting that demonstrated CTIM-76 was well tolerated and induced dose-proportional tumor regressions in models of CLDN6-positive cancer. Benchmarking studies were conducted to compare CTIM-76 to clones of other CLDN6 clinical-stage compounds, including TORL-1-23 and AMG-794. In these studies, CTIM-76 was potent across a wide-range of CLDN6 expression profiles, whereas TORL-1-23 potency was limited to CLDN6-high expression. In addition, CTIM-76 demonstrated ten-fold higher potency than that of AMG-794 in in vitro cytotoxicity and cytokine activation assays."
