Carisma LinkedIn: We are thrilled to announce the appointment of leading solid tumor immunotherapy expert Padmanee Sharma, MD, PhD to our Scientific Advisory Board (SAB). The addition of Dr. Sharma to our SAB comes at an exciting time as we expand our proprietary targeted chimeric antigen receptor macrophages (CAR-M) in combination with other therapies, including the combination study of CT-0508, a human epidermal growth factor receptor 2 (HER2) targeted CAR-M with Merck’s anti-PD1 therapy KEYTRUDA® (pembrolizumab) for the treatment of HER2 overexpressing cancers. Dr. Sharma’s scientific knowledge in immunotherapy will prove invaluable as we continue to advance CAR-M products through the clinic.
