About BTX-1188

Biotheryx’s lead molecular glue drug candidate BTX-1188 is a dual protein degrader which was designed to degrade GSPT1, a promising cancer target, and IKZF1/3 (also known as Ikaros/Aiolos), both clinically validated anti-inflammatory and immunomodulatory targets. Prior literature has demonstrated that degradation of GSPT1 can result in antitumor activity in difficult-to-treat tumors such as acute myeloid leukemia (AML) and in solid tumors, including those that overexpress oncogenic transcription factors, such as MYC, however, prior clinical research by others has shown that administration of a GSPT1-only degrader was associated with dose-limiting toxicities related to the release of pro-inflammatory cytokines. BTX-1188 was specifically designed as a potent degrader of GSPT1 that can also directly block inflammation by degrading IKZF1/3. In preclinical studies conducted by Biotheryx, administration of BTX-1188 led to complete eradication of tumors and extended survival in xenograft models of AML. BTX-1188 also led to potent cell killing in a number of cell lines derived from solid tumors. BTX-1188 is currently being evaluated in a Phase 1 dose-escalation trial in patients with hematologic and solid tumor malignancies.
