Clinical Trial Progress And DesignAPEX Phase 2 is actively dosing at multiple clinical sites with enrollment focused on patients with combined pre/post-capillary pulmonary hypertension and pulmonary vascular resistance as the primary endpoint to increase the chance of detecting a meaningful treatment effect.
Pipeline Diversification And MechanismA first-in-class APJ antagonist program and a long-acting subcutaneous TX2100 alongside TX45, which has a distinct pharmacokinetic profile, broaden the pipeline and could expand the company's addressable market if early studies show activity.
Safety And ToxicologyNonhuman primate toxicology studies reported no key safety signals and independent safety reviews found no concerns, supporting continued clinical development of the lead program.
