This post was originally published on this site

TAIPEI, July 1, 2024 /PRNewswire/ — Anbogen Therapeutics, Inc., a clinical-stage company dedicated to developing breakthrough cancer therapies, has announced the successful closing of a USD 7.3M oversubscribed A+ round financing, which is a direct continuation of the USD 12.5 Million Series A on 1st February, 2024, bringing the total raised to USD 19.8M. The funds from the A+ round will be specifically used to advance the Phase II clinical trial of ABT-301. The financing round was led by KGI Venture Capital and both new and existing investors.

The capital raised in the A+ round will primarily be used to support the Phase II clinical trial of ABT-301 in combination with PD-1 inhibitors for treating microsatellite stable (MSS) metastatic colorectal cancer, which accounts for 95% of the metastatic colorectal cancer population that does not benefit from immune checkpoint inhibitors. Previous preclinical studies have repeatedly showed that ABT-301, when combined with immune checkpoint inhibitors, exhibits remarkable synergistic therapeutic effects in various solid tumor models, including subcutaneous xenograft and orthotopic models of colorectal cancer, liver cancer, triple-negative breast cancer, and head and neck cancer.

Given these promising results, Anbogen decided to proceed with the A+ round of financing to secure the necessary funds for ABT-301’s clinical trial, without impacting the ongoing Phase II development of ABT-101.

Leveraging ABT-301’s compelling immunomodulatory and synergistic effect combined with PD-1 treatment that Anbogen has observed, we have successfully engaged pharmaceutical companies who will agree to enter PD-1 drug-supply agreement with Anbogen. This collaboration will enable Anbogen to optimize its resource allocation and underscores the strong recognition of both ABT-301 and Anbogen.

“We are deeply grateful to our investors for their continued support and confidence in our mission,” says Dr. Tsu-An Hsu, CEO of Anbogen Therapeutics. “This funding is crucial for the advancement of ABT-301 combo with immune checkpoint inhibitors treating solid tumors, and it validates our ongoing efforts to bring effective cancer treatments to patients in need.”
