Press Release from CoA Therapeutics on Phase 1 Study for PKAN

from | June 7, 2022

We hereby issue the following press release from CoA Therapeutics:

"CoA Therapeutics and BridgeBio Pharma present data from Phase 1 study in healthy subjects to support development of BBP-671 for PKAN and organic acidemias.

On May 26, 2022, CoA Therapeutics and parent company BridgeBio Pharma reported interim results from a Phase 1 study of BBP-671 in 77 healthy subjects. BBP-671, which has not been approved by the FDA or any other agency, is an oral small molecule therapy that activates pantothenate kinase enzymes. BBP-671 is being developed as a potential therapy for diseases associated with coenzyme A (CoA) deficiency, including pantothenate kinase-associated neurodegeneration (PKAN), propionic acid anemia and methylmalonic acid anemia.
In Phase 1 trials, researchers test a new potential therapy on healthy individuals to gather information about how a drug interacts with the human body. This early information feeds into future clinical trials. In the study, BBP-671 was generally well tolerated by the healthy volunteers. No serious side effects occurred. The most common adverse reactions associated with BBP-671 administration were headache (3 subjects), neutropenia (3 subjects), abdominal pain (1 subject), and nausea (1 subject). In individuals who experienced neutropenia, a decrease in white blood cell counts, white blood cell counts returned to normal within 3 days when BBP-671 was stopped.
BBP-671 has been detected in blood and cerebrospinal fluid, the fluid surrounding the brain, suggesting that BBP-671 can cross the blood-brain barrier and reach the brain.
In healthy individuals, CoA is formed in the body by pantothenate kinase enzymes that degrade pantothenate (vitamin B5) to produce CoA and acyl-CoAs, including acetyl-CoA. BBP-671 appears to increase acetyl-CoA levels and decrease pantothenate levels in the blood of healthy subjects administered BBP-671. These biomarker changes demonstrate for the first time in humans that BBP-671 acts as expected in the body.
Based on these data, CoA Therapeutics and parent company BridgeBio Pharma plan to proceed with the second part of the Phase 1 clinical trial in subjects with propionic acidemia and methylmalonic acidemia in the second half of 2022 and initiate a Phase 2/3 clinical trial in subjects with PKAN in 2023.
