pHLIP, Inc. sublicensee, Cybrexa Therapeutics, has entered into an exclusive collaboration agreement with Exelixis, Inc. (Nasdaq: EXEL) providing Exelixis the right to acquire CBX-12. CBX-12 is composed of a pH-Low Insertion Peptide (pHLIP®), a linker and exatecan. Data from the ongoing phase 1 trial of CBX-12 in patients with metastatic solid tumors demonstrated preliminary anti-tumor activity in a heavily pretreated patient population. This included a complete response in a patient with ovarian cancer.
Under the terms of the agreement, Exelixis will pay Cybrexa an upfront fee of $60 million in exchange for the right to acquire CBX-12 pending certain Phase 1 results and to fund certain development and manufacturing expenses incurred by Cybrexa to advance an agreed development plan. Cybrexa may also be eligible to receive up to an additional $642.5 million, including development, regulatory, and commercial milestone payments, as well as a fee for the acquisition of CBX-12 upon evaluation of a pre-specified clinical data package.

The University of Rhode Island and Yale University granted pHLIP, Inc exclusive worldwide commercial rights for composition of matter and methods of use of pHLIP® immuno-modulator compounds protected by a patent application developed by founders of the company and filed in September 2022.
The first patient has been dosed in a phase I/IIa fluorescence-guided surgical clinical trial evaluating pHLIP® ICG imaging agent. The purpose of this study is to see whether the use of the fluorescent imaging agent pHLIP® ICG and NIRF imaging during surgery is a safe approach that may allow the surgeon to image tumor bed and established tumor margins. The ClinicalTrials.gov identifier is NCT05130801, https://clinicaltrials.gov/ct2/show/NCT05130801
The U.S. Food and Drug Administration (FDA) has provided green light to initiate first in human clinical studies of pHLIP® ICG imaging agent. pHLIP® ICG will be administered to breast cancer patients in a phase 1/2a fluorescence-guided surgical trial at Memorial Sloan Kettering Cancer Center. Fluorescence guidance by pHLIP® ICG during surgical procedures is expected to improve visualization of primary tumor masses and satellite cancerous lesions and allow accurate margin delineation to improve surgical outcomes.
