BioTheryX Doses First Patient in Phase 1 Study Investigating Lead Protein Degrader Candidate BTX-1188

Study to Evaluate the Safety, Pharmacokinetics and Preliminary Efficacy of BTX-1188 in Patients with Advanced Hematologic and Solid Tumor Malignancies

SAN DIEGO, Jan. 26, 2022 — BioTheryX, Inc., a clinical-stage company focused on developing targeted protein degraders to create life-saving medicines, today announced dosing of the first patient in a new, first-in human Phase 1 study investigating its lead candidate BTX-1188, an oral, dual target protein degrader specifically engineered to degrade GSPT1 and IKZF1/3, in patients with advanced hematologic and solid tumor malignancies.

“BTX-1188 has demonstrated rapid, deep and durable degradation of both GSPT1 and IKZF1/3 at low nanomolar concentrations in preclinical models, and we are delighted to make this exciting advancement into the clinic,” said Zung Thai, M.D., Ph.D., Chief Medical Officer of BioTheryX. “We are grateful to our clinical trial site partners for initiating this study in these challenging times and thank them for their commitment to investigating potential new therapeutic options for people facing difficult-to-treat cancers.”

The Phase 1 clinical trial is a multicenter, open label, non-randomized, sequential dose escalation study to assess the safety, pharmacokinetics and preliminary efficacy of BTX-1188 in patients with acute myeloid leukemia, advanced lymphoid and solid tumors who have failed standard therapy. The primary objective of the Phase 1 study is to determine a recommended Phase 2 dose, which will then be carried forward into expansion cohorts where the safety and efficacy of BTX-1188 will be evaluated in both hematologic and solid tumor malignancies. More information can be found on clinicaltrials.gov (NCT05144334).

“BTX-1188 is one of many potential best-in-class protein degrader candidates our team has designed and developed leveraging our distinctive PRODEGY targeted protein degradation platform to provide new treatment approaches for people living with cancer and other diseases,” said Philippe Drouet, President and Chief Executive Officer of BioTheryX. “With our clinical trial site partners, we are working as expeditiously as possible to study BTX-1188 and validate the potential of our platform.”

About BTX-1188

BTX-1188 is the first orally bioavailable, rationally designed dual target protein degrader, engineered to specifically degrade validated oncology targets GSPT1 and IKZF1/3. By degrading GSPT1 and IKZF1/3, BTX-1188’s profile is expected to be differentiated from protein degraders that exclusively target GSPT1. Preclinical data for BTX-1188 has shown rapid, deep and durable degradation of these targets at low nanomolar concentrations. Acute myeloid leukemia (AML) xenograft experiments have also shown significant decreases in tumor volume and increased survival compared to controls and other degraders of GSPT1. BioTheryX believes BTX-1188 has broad potential applicability in both hematologic and solid tumor malignancies and is currently studying the molecule in both settings as part of a Phase 1 clinical study.

BioTheryX Receives IND Clearance from FDA to Proceed with Phase 1 Study of BTX-1188, a Molecular Glue, for the Treatment of Hematologic and Solid Malignancies

Enrollment for Phase 1 Clinical Trial to Commence by End of 2021

SAN DIEGO, Nov. 2, 2021 /PRNewswire/ —

BioTheryX, Inc., a clinical-stage company focused on targeted protein degradation to create life-saving medicines, today announced that the U.S. Food and Drug Administration (FDA) cleared the company to proceed with a Phase 1 clinical trial of BTX-1188 in hematologic and solid malignancies.

BTX-1188 is a novel oral small molecule cereblon binder that has immunomodulatory properties and promotes the degradation of a neosubstrate G1 to S phase transition 1 (GSPT1), a translation termination factor, as well as IKZF1/3, zinc finger transcription factors important in hematological function. By degrading multiple proteins including GSPT1 and IKZF1/3, BTX-1188’s profile is expected to be differentiated from protein degraders that exclusively target GSPT1. BTX-1188 has demonstrated promising preclinical activity against a variety of leukemias and solid tumors.

“The FDA clearance to begin our Phase 1 study for BTX-1188 is a major milestone for BioTheryX, which represents our first molecular glue to enter clinical development, and the second IND clearance for our pipeline,” said Zung Thai, M.D., Ph.D., Chief Medical Officer of BioTheryX. “We plan to study BTX-1188 in patients with hematological and solid malignancies who have limited treatment options and for whom new therapies are desperately needed. We expect to initiate patient enrollment in the Phase I study by year end.”

The Phase I clinical trial is designed to assess the safety and tolerability of BTX-1188 and to determine the recommended Phase 2 dose. Following determination of the recommended Phase 2 dose, the company plans to further evaluate the safety and efficacy of BTX-1188 in expansion cohorts in both hematological and solid tumor malignancies.

BioTheryX Announces First Patient Dosed with BTX-A51 in Phase 1 Clinical Trial in Patients with Advanced Solid Tumors

SAN DIEGO, June 9, 2021 /PRNewswire/ —

BioTheryX, Inc., a clinical-stage company focused on degrading proteins to create life-saving medicines, today announced the dosing of the first patient in a dose escalation clinical trial of BTX-A51 in advanced solid tumor malignancies that are dependent upon MYC, one of the most commonly known oncogenic drivers. BTX-A51, the company’s lead multi-kinase inhibitor is also currently in a phase 1 dose escalation clinical trial for advanced hematological malignancies.

“This is a significant milestone for BioTheryX, as we look to deliver a much-needed therapeutic option to patients with advanced solid tumor malignancies that are dependent upon MYC,” said Robert Williamson, President and CEO of BioTheryX.  “We are excited for the potential of BTX-A51 to provide a meaningful therapeutic option for patients and are working aggressively to advance our pipeline of molecular glues, Proteolysis Targeting Chimeras and monovalent degraders towards the clinic.”

BTX-A51 is an oral small molecule, multi-kinase inhibitor designed to block a specific leukemic stem cell target (CK1α) as well as super enhancer targets (CDK7/CDK9) preventing transcription of key oncogenic genes. This therapeutic mechanism entails activation of p53, an important tumor suppressor, and its sustained stabilization by super-enhancer shutdown of MDM2, a protein degrader of p53, in combination with transcriptional shutdown of leukemia oncogenes, such as MYC and MCL-1.  Blocking CKIα, CDK7, and CDK9 augments and synergistically stabilizes p53 and downregulates MYC and MCL-1 promoting the rapid killing of leukemia cells as well as leukemic stem cells. Pre-clinical results have been published in a peer-reviewed Cell article, demonstrating BTX-A51’s favorable efficacy in animals.

“In the fight against solid tumor cancers, which have extremely poor survival rates and limited treatment options, clinical trials with new therapies are desperately needed,” added Zung Thai, M.D., Ph.D., Chief Medical Officer of BioTheryX.  “We are excited to be initiating the dose escalation portion of this study and progressing to the selection of the Phase 2 dose.”

BioTheryX’s Phase 1 clinical trial of BTX-A51 is currently ongoing and recruiting patients.   The clinical trial is designed to assess the safety and tolerability of BTX-A51 and to determine the recommended Phase 2 dose.  Following determination of the recommended Phase 2 dose, we plan to further evaluate the safety and efficacy of BTX-A51 in expansion cohorts in both hematological and solid tumor malignancies.
