Cybrexa Therapeutics to Present First Data and Unveil Details for its alphalex™-PARP Inhibitor Lead Candidate CBX-11 at AACR Annual Meeting 2019

New Haven, Conn., March 18, 2019 – Cybrexa Therapeutics, a biotechnology company developing a new class of cancer therapeutics through its alphalex™ tumor targeting platform, today announced that Vishwas Paralkar, PhD, Chief Scientific Officer of Cybrexa, will present the first set of preclinical data supporting its alphalex™-PARP inhibitor lead candidate, CBX-11, at the American Association for Cancer Research (AACR) Annual Meeting 2019, being held March 29 – April 3 in Atlanta, Georgia. At the meeting, the Company will unveil the FDA-approved poly ADP-ribose polymerase (PARP) inhibitor conjugated in CBX-11.


CBX-11 combines Cybrexa’s proprietary alphalex™ tumor targeting technology with an already-approved oral small molecule PARP inhibitor. CBX-11 will be evaluated in combination with DNA damaging chemotherapy for the treatment of patients with solid tumors that lack homologous recombination deficiency (HRD). The company remains on track to submit its Investigational New Drug (IND) application for CBX-11 by the fourth quarter of 2019, with a Phase 1 clinical trial evaluating CBX-11 in combination with chemotherapy anticipated to begin in the first quarter of 2020.


Details for the poster presentation are as follows:


Targeting solid tumor acidic microenvironment with an alphalex PARP inhibitor

Permanent Abstract # 2981 / Poster #3

Session: Diagnostics, Biomarkers, and the Tumor Microenvironment

Date and Time: Tuesday, April 2; 8:00 am – 12:00 pm EST

Location: Georgia World Congress Center, Exhibit Hall B, Poster Section 11

Presenting Author: Vishwas Paralkar, PhD, Chief Scientific Officer of Cybrexa


“This marks the first set of preclinical data supporting our lead candidate CBX-11, which we formally announced at the beginning of the year,” said Vishwas Paralkar, PhD, Chief Scientific Officer of Cybrexa. “Our alphalex™ tumor targeting technology represents a novel approach to enable the synergistic efficacy of a PARP inhibitor and chemotherapy administered at full dose. We are excited to share these compelling data and take the opportunity to unveil the composition of CBX-11, especially given the current development landscape and high profile of PARP inhibitors.”


About the alphalex™ Technology Platform

The Cybrexa alphalex™ technology platform enables the delivery of small molecules across the cell membrane under low pH conditions, which is a universal feature of cancer cells. As a result, alphalex™ technology – which consists of a novel peptide, linker and small molecule anti-cancer agent – allows for antigen-independent, intracellular delivery of small molecule anti-cancer agents directly into the tumor cell.
