LIXT
LIXTE Biotechnology Holdings, Inc. is a clinical-stage pharmaceutical company developing a new class of cancer therapies called Protein Phosphatase 2A (PP2A) inhibitors. The company's lead compound, LB-100, is a first-in-class molecule designed to enhance the efficacy of existing treatments, including chemotherapy and immunotherapy. By inhibiting the PP2A enzyme, a critical regulator of cellular functions, LB-100 aims to overcome treatment resistance in cancer cells. This approach seeks to improve outcomes for a broader range of patients by increasing the effectiveness of standard oncology therapies. The compound has demonstrated synergy with both chemotherapy and immunotherapy in pre-clinical models.
