Cumberland Pharmaceuticals and Vanderbilt Health Announce Ifetroban Clinical Trial Data

Cumberland Pharmaceuticals and Vanderbilt Health announce data from a Phase 2a clinical trial of ifetroban to prevent metastasis in high-risk solid tumors. The study's primary safety endpoint was achieved, along with favorable trends in decreased metastasis recurrence and metastasis-free survival. A safe and effective medication that reduces distant metastatic recurrence could transform cancer management and improve the lives of millions of cancer survivors and their families. The randomized, double-blind, placebo-controlled Phase 2a trial evaluated the safety of ifetroban, an investigational thromboxane A2 receptor antagonist, in patients with solid tumors at high risk of early metastatic recurrence. Cancer types included breast, lung, pancreatic, soft tissue, bladder, and renal cancers. The study met its primary endpoint, demonstrating that ifetroban was safe and well-tolerated in this patient population. Rates for adverse events related to treatment were similar between placebo and ifetroban. No serious adverse events in either group were identified as being related to study treatment. Treatment discontinuation rates were not statistically different between placebo and ifetroban. Although primarily a safety study and intentionally not powered for efficacy, the study compared the percentage of patients with distant metastatic recurrence 12 months after completion of therapy in both groups (10 placebo-treated and 18 ifetroban-treated participants) as a prespecified secondary endpoint. While 50% of participants experienced distant metastatic recurrence in the placebo arm, only 17% of participants experienced distant metastatic recurrence in the ifetroban arm. Three deaths due to distant metastatic disease occurred in the placebo arm, and none occurred in the ifetroban arm.
