CG Pharmaceuticals: Progress of U.S. Phase 1b/2 Metastatic Pancreatic Cancer Clinical Trial at the ASCO Gastrointestinal Symposium

Excerpt from the Press Release:

ORINDA, Calif., Jan. 23, 2025 /PRNewswire/ — CG Pharmaceuticals (CG Pharma), a clinical biopharmaceutical company located in the San Francisco Bay Area, was established as an independent entity in 2024 after licensing ivaltinostat from CG Invites. The company has since been conducting various research projects on ivaltinostat in the U.S. including the metastatic pancreatic cancer (mPDAC) clinical trial (NCT05249101). The results of the completed Phase 1b study and the progress report of Phase 2 will be presented at the ASCO Gastrointestinal Symposium on Friday, January 24.

In the Phase 1b study, a total of 28 patients with locally advanced or metastatic PDAC who had received at least one prior line of therapy were administered ivaltinostat at 3 different dose levels (60, 125 and 250 mg/m² on days 1 and 8) in combination with capecitabine (1000 mg/m², administered twice daily on days 1-14) of a 21-day cycle.

Treatment-emergent adverse event (TEAE) profile was similar across dose levels, with the most common TEAEs (primarily grade 1-2) including fatigue, nausea, palmar-plantar erythrodysesthesias, constipation, and diarrhea. No serious adverse events that were related to ivaltinostat occurred in any of the 3 dose cohorts.

At the time of data cutoff (12/28/2024), there were 7 patients still alive, 18 deaths (all due to disease progression after discontinuation from study; no deaths directly related to study treatment), 1 patient lost to follow-up, and 2 study withdrawals. The longest-surviving patient has been alive for 27 months and the maximum duration of treatment was 20 months. Two thirds (65%) from a total of 28 patients showed stable disease or no evidence of disease, 14% experienced disease progression, and 22% were not evaluated.
