CAR-T agent for refractory met-pancreas showing a median duration of response of 9.5 months. These treatments are far from widely available, but the proof of principle is nice to see in a disease that otherwise has not had responses to immunotherapy. Hopefully more agents to come.
Asian study of nimotuzumab (humanized EGFR-inhibitor) + gemcitabine (gem) vs. gem alone. The overall survival (OS) was 10.9 vs. 8.5 months in favor of the combination arm. While the OS difference is small, recall that the OS in the NALIRIFOX and FOLFIRINOX studies are similar. The safety profile of nimotuzumab + gemcitabine is superior to a triplet or double cytotoxic chemotherapy combination regimen. This drug is currently not available in the USA but is approved for nasopharyngeal carcinoma in China.
You may have enrolled a patient in this trial, but it seems we may have a new first line regimen. Surprisingly toxicity simar in both arms, but there was improvement in PFS and OS (17% reduction in death) although it wasn’t statistically significant in OS.
More diarrhea with nalirifox, but more neutropenia with gem abraxane.
Somewhat disappointing as this was a negative study, however it is still an option for patients who are not candidates for mFOLFIRINOX.
Positive study for the combo of TMZ + cape vs. TMZ alone in met-pNET, confirming a regimen that is already widely used. Patients were first-line, and those with MGMT-def had a better response.
The NAPOLI-3 study assessed FOLFOX+ liposomal irinotecan vs. gemcitabine + nab-paclitaxel. NALIRIFOX was superior, with an OS of 11.1 vs. 9.2 months. Criticisms of modern gem trials are often that of rigid dosing requirements that differ from modern clinical practice. Additionally, it is unclear whether NALIRIFOX provides any meaningful benefit over FOLFIRINOX, and the cost is always a consideration.
Another maintenance trial, NO statistically significant OS benefit but prolonged time to second-line chemotherapy. HR was favored Olaparib.
Long term results on adjuvant FOLFIRINOX vs Gem in adjuvant pancreatic cancer. Although the survival benefit is quite significant (OS 53.5 vs 35.5 months respectively), I think the tell-tale numbers are the 5 year DFS being 26.1 vs 19%. The modest 7% curative benefit of triplet vs single agent chemotherapy highlights the difficulty in managing this disease and the continued need for investment in GI clinical trials.
Very interesting study which gives more support for preoperatory therapy in the setting of borderline resectable pancreatic cancer. The use of neodjuvant chemotherapy or chemoradiotherapy will likely increase overtime, as systemic options improve, even in pancreatic cancer. Optimal regimen is unknown as studies with other options such as Folfirinox, gemcitabine/albumin-bound paclitaxel are needed, post chemoradiotherapy.
