Comanche Biopharma Receives US FDA Fast Track Designation for CBP-4888 for the Treatment of sFlt-1 mediated pre-term preeclampsia

Concord, Mass., August 23, 2023 — Comanche Biopharma Corp. today announced that they have received Fast Track designation from the U.S. Food and Drug Administration (FDA)for the investigation of CBP-4888 for the treatment of sFlt1-mediated pre-term preeclampsia. CBP-4888 is a subcutaneously delivered siRNA therapeutic that is currently in a Phase 1 clinical trial. The FDA’s Fast Track program is designed to facilitate the development, and expedite the review of, novel potential therapies that are designed to treat serious conditions and address an unmet medical need. 

“We are grateful to the FDA for recognizing the potential of our novel siRNA investigational drug, CBP-4888, to help address the escalating maternal health crisis,” said Scott Johnson, M.D., Co-Founder and CEO of Comanche Biopharma. “This designation offers increased collaboration with the FDA to help ensure that CBP-4888 reaches patients expeditiously while maintaining the highest standards of safety and quality.”

Preeclampsia afflicts more than 10 million women every year around the world with devastating short- and long-term consequences to both mother and baby. Currently no existing therapy can modify the disease progression of preeclampsia. “Complications from preeclampsia lead to approximately 80,000 maternal and 500,000 fetal and newborn deaths globally every year,” said Allison August, M.D., Chief Medical Officer of Comanche Biopharma. “Currently, the only cure for preeclampsia is premature delivery. Today’s FDA Fast Track designation brings us one step closer to our shared goal of advancing a safe and effective treatment option for patients with preeclampsia.”

Comanche is committed to lowering the risks of pregnancy and prematurity worldwide by safely sustaining natural pregnancy.

About CBP-4888

CBP-4888 is a fixed-dose combination of two chemically-synthesized, lipid-conjugated small interfering ribonucleic acid (siRNAs) duplex oligonucleotides (siRNA-2283 and siRNA-2519) targeting two soluble fms-like tyrosine kinase–1 (sFLT1) mRNA isoforms. 

About Preeclampsia

Preeclampsia is a prevalent and serious pregnancy complication that affects up to 8% of pregnancies worldwide. It can lead to a range of complications for both the mother and the baby, including multi-organ damage, seizures, and premature birth. Globally there are an estimated 80,000 maternal deaths and 500,000 fetal and newborn deaths annually due to this pregnancy complication. While preeclampsia can develop in any pregnancy, it disproportionately affects black individuals, those living in low- and middle-income countries, and those residing in rural areas.

The signs and symptoms of preeclampsia can vary and include high blood pressure, acute kidney injury, swelling in the hands and face, severe headaches, vision changes, and abdominal pain. Treatment may include close monitoring of blood pressure and urine protein levels, bed rest, and medication to lower blood pressure. Currently, delivery of the baby is the only definitive cure for preeclampsia.
