Abbisko Therapeutics Reports Phase 2 Study on Pimicotinib

Presentation of Pimicotinib Study Results at ASH

Abbisko Therapeutics has made significant strides in the battle against chronic Graft-versus-Host Disease (cGvHD) with the presentation of preliminary Phase 2 study results for pimicotinib (ABSK021). The results indicate that this innovative treatment may be a game-changer for patients suffering from this complicated condition. The research uncovered encouraging data during the annual meeting, indicating that the drug achieved a remarkable overall response rate (ORR) among participants with challenging cGvHD conditions.

Impressive Efficacy Observed

Initial findings revealed an ORR of 64% among patients receiving pimicotinib at a dosage of 20mg once daily. This promising data emerged from a subset of patients who had either progressed or not responded to previous therapies. Although many participants had not yet completed the six-month treatment cycle required to fully assess response factors, the preliminary results were hopeful and indicated effectiveness across multiple organs.

Details of Response in Affected Organs

Patients responded positively across various affected areas, including the gastrointestinal tract, oral cavity, eyes, skin, and even the lungs. Specifically, the respiratory implications of cGvHD characteristically present severe challenges. The presentation discussed vital findings regarding pulmonary health, emphasizing remarkable enhancements in lung function for several participants.

Insights into Lung Health Improvements

Among the six patients observed, notable improvements were recorded: one subject exhibited an 11% increase in forced expiratory volume in the first second (FEV1), while another returned to a normal FEV1 of over 75%. The remaining four participants also displayed significant improvements in shortness of breath and overall lung health. These results underscore pimicotinib's potential in addressing severe pulmonary manifestations linked with cGvHD.

Long-term Treatment Potential

As the study moved forward, it became clear that most enrolled patients had not reached the completion of their treatment cycles. This indicates the potential for further improvements in outcomes with longer exposure to pimicotinib. Initial analyses revealed that pimicotinib is not only effective but also well-tolerated in patients with challenging medical histories.

Clinical Safety and Tolerability

Feedback from patients indicated a considerable reduction in specific organ-related symptoms associated with cGvHD. Most adverse events reported were Grade 1, illustrating that pimicotinib may represent a safe and viable treatment alternative. Patients and physicians are optimistic, as the potential therapeutic avenues for managing cGvHD evolve.
