Dr. Frohlich is a medical oncologist and brings more than 25 years of experience developing cellular immunotherapies to treat cancer, including deep expertise in clinical drug development and translational research, and portfolio strategy.  

"We are pleased to have Mark join our Board," said Raul Rodriguez, Rigel's president and CEO.

Prior to joining Indapta, Dr. Frohlich served as a consultant and strategic advisor for several immuno-oncology biotechnology companies. Before that, he led portfolio strategy at Juno Therapeutics, which developed the FDA-approved CAR T-cell therapy Breyanzi^® for large B-cell lymphoma, until the company was sold to Celgene, now part of Bristol Myers Squibb. Prior to joining Juno, he held various roles at Dendreon Corporation, a pioneer in the development of cellular immunotherapy, with his most recent role being chief medical officer and executive vice president of Research & Development. At Dendreon, he led the clinical team responsible for the development and U.S. and European regulatory approval of PROVENGE^®, one of the first commercially available cancer immunotherapies.

At UCSF, he served as chief resident in medicine and completed a fellowship in hematology/oncology and a Howard Hughes postdoctoral fellowship.

"I am excited to join Rigel as it continues to advance its development pipeline," said Dr. Frohlich. "I believe the IRAK1/4 and IDH1 inhibitor programs have a significant potential to benefit patients with lower-risk myelodysplastic syndrome and glioma, respectively. I look forward to collaborating with the team as we further study these product candidates with the goal of bringing them to patients that need new treatment options."
