sonrotoclax (BGB-11417)
Sonrotoclax, BeiGene’s clinical-stage, orally bioavailable, next-generation inhibitor, targets both WT and mutated forms of the Bcl-2 protein by binding within a hydrophobic groove, similar to other inhibitors in its class. Explore this case study to see how sonrotoclax was rationally designed to potency against both WT and mutant Bcl-2 and address the limitations of first-generation inhibitors and more!
NDI-101150
NDI-101150 is an oral HPK1 inhibitor discovered by Nimbus Therapeutics and is currently in Ph. I/II clinical trial in advanced solid tumors. HPK1 is a compelling immuno-oncology target due to its critical role in regulating T-cells, B-cells, and dendritic cell-mediated immune responses. HPK1-deficient mice demonstrate enhanced anti-tumor T-cell responses and resistance to tumor growth. In this article, we detail the discovery of NDI-101150, as highlighted by Nimbus at the ACS Fall 2024 First-Time Disclosures session, interim results from the clinic, and more.
TYRA-300
Tyra Biosciences’ lead asset, TYRA-300, is a potent, selective, and orally bioavailable FGFR3 inhibitor designed to mitigate the toxicities commonly seen with pan-FGFR inhibitors. A key objective of the program was to meet the safety standards required for advancing into pediatric populations for the treatment of ACH (achondroplasia) and other skeletal dysplasias. TYRA-300 is currently being evaluated in Ph. I clinical trials for advanced urothelial cancers and other solid tumors and, importantly, has received IND clearance to initiate a Ph. II clinical trial in pediatric ACH patients.
MORF-627
Morphic Therapeutic’s MORF-627 is an oral αvβ6 integrin inhibitor designed to treat IPF by blocking the TGFβ pathway. The Morphic team leveraged SBDD and FEP+ during lead optimization to enhance permeability and isoform selectivity. This article highlights the team’s focus on inhibiting the “bent-closed” conformation of αvβ6 as well as the linker design that led to the “chameloenicity” of the lead compound. The impressive multispecies PK and in vivo efficacy of MORF-627 in preclinical models was unfortunately accompanied by oncogenic toxicity that prevented it from reaching clinical trials.
inavolisib
Inavolisib is a PI3Kα isoform-selective kinase inhibitor and monovalent degrader of the mutant p110α catalytic subunit of mutant PI3Kα. The molecule selectively depletes mutant p110α in cancer cells with active RTK (receptor tyrosine kinase) signaling and is in several ongoing or planned Ph. III trials for breast cancer. In October 2024, it received FDA approval for use in combination with palbociclib and fulvestrant to treat adults with endocrine-resistant, PIK3CA-mutated, HR+/HER2- breast cancer. This article explains how it works, how it was discovered, and why it matters.
