New Results from Ph 2 Trial Confirm Benefit of Trilaciclib in Reducing Adverse Events Related to an ADC

“These preliminary results continue to show the consistent benefit of trilaciclib when administered prior to sacituzumab, relative to the previously published single agent safety profile of this ADC, including greater than 50 percent reductions in the incidence of events including neutropenia, anemia, and diarrhea,” said Raj Malik, M.D., Chief Medical Officer at G1 Therapeutics. “It is too early to determine the efficacy of trilaciclib prior to sacituzumab in this patient population. However, early indications suggest a higher response rate in patients with PD-L1 positive tumors, which commonly have an immune inflamed tumor microenvironment and are thus more likely to respond early to immunotherapies. Given that this trial includes a heavily pretreated patient population, we are enthusiastic about these data to date. We will continue to monitor efficacy to assess the potential of trilaciclib to improve overall survival – by protecting the immune system and stimulating long term immune surveillance – when combined with additional treatment regimens beyond gemcitabine/carboplatin for patients with TNBC. We look forward to these overall survival data in the first quarter of 2024.”
