BH-30643
A mutant-selective OMNI-EGFR™ inhibitor
We are evaluating a potentially better way to treat EGFR-positive NSCLC. BH-30643 is a mutant-selective OMNI-EGFR™ inhibitor with an aim to provide greater benefit to patients by:
- Super-high potency against common, atypical and compound EGFR mutations, including those induced by treatment with other EGFR inhibitors.
- Low potency against wild-type EGFR to decrease the risk of toxicities associated with wild-type EGFR activity, including skin rash.
- Concurrently targeting active EGFR and HER2 to reduce the chances of resistance.
BH-30643 has demonstrated a promising PK and safety profile, including good preclinical cardio-safety. The company is actively enrolling the Phase 1/2 SOLARA clinical trial.
BH-30236
A Multi-Targeted CLK Inhibitor
Our orally available, multi-targeted CLK inhibitor BH-30236 is designed to selectively induce splicing alterations in cancerous tissue and shut down cancer’s ability to use off-target resistance mechanisms. We aim for BH-30236 to be applied to hematologic cancers and solid tumors. The first indications for its use are in treating adult AML and higher-risk myelodysplastic syndrome (HR-MDS).
Candidate Selection
ALK/CLK Dual Inhibitor
ALK inhibitors have been successful in the treatment of ALK+ cancers, with four ALK inhibitors now approved. However, ALK mutations have emerged for all four approved treatments. In addition to these on-target mutations, it has been shown that aberrant splicing functions as an oncogenic driver and induces off-target treatment resistance in these cancers.
Targeting CLK kinases can be an effective strategy in modulating aberrant alternative splicing in cancer and cancer treatment resistance. Our approach addresses both on-target and off-target mutations driving treatment resistance via dual inhibition of ALK/CLK.
Our programs show promising activity against CLK1/2/4 to suppress survival signals and promote cell death in cancer cells, including those with TP53 mutations. Our approach could help minimize or prevent treatment resistance to approved medicines such as LORBRENA®, ALECENSA® and VENETOCLAX®.
With favorable pharmacokinetic profiles, we expect to select a candidate, initiate IND-enabling studies in 2024, and start clinical studies in early 2025.
