Cosela (trilaciclib)

On the basis of 110 ns MD simulations, it was concluded that trilaciclib, tucatinib and olmutinib can be considered candidate inhibitors for HsFN3K inhibition. These drugs are expected to have favourable in-vitro and in-vivo activity inhibiting HsFN3K on the basis of our results.

Here, in four randomized clinical trials, we show that the CDK4/6 inhibitor trilaciclib, given in conjunction with a variety of chemotherapeutic regimens and across diverse populations of patients with cancer, mitigates chemotherapy-related expansion of CH clones with mutations in DNA damage response genes, including TP53. This finding was also observed in a syngeneic mouse model of TP53-mutant CH, demonstrating that CDK4/6 inhibition blocks platinum-induced TP53 competitive repopulation through promoting hematopoietic stem and progenitor quiescence and decreasing the stemness advantage of TP53-mutant clones. This represents a proof of concept for a potential pharmacologic strategy to block chemotherapy-induced expansion of preleukemic TP53-mutant clones.

The primary endpoint is overall response. Key secondary endpoints include progression-free survival, duration of response, and overall survival.Clinical trial registration: www.clinicaltrials.gov identifier is NCT06027268.

Additionally, activated CD8+ T cells recruit and activate neutrophils, forming a positive feedback loop. Combining trilaciclib with anti-PD-1 antibodies presents a promising strategy for NSCLC treatment.
