Peak Bio, Inc. Awarded Patent with Broad Coverage for Thailanstatin-ADC platform technology (PH-1) a Payload with Novel Immunomodulatory Effects that Target RNA Splicing
Pleasanton, CA, Jan. 04, 2024 (GLOBE NEWSWIRE) — Peak Bio, Inc. (“Peak Bio” or the “Company”) (OTCQB) PK: PKBO), announced that it was awarded US Patent No. 11,691,982 B2 entitled “Thailanstatin Analogs” by The United States Patent and Trademark Office (USPTO). The new patent describes properties of potent heteroaryl-substituted Thailanstatin payloads, proprietary non-cleavable and cleavable linkers, and antibody-drug conjugate (ADC) technology derived from it. Peak Bio is a clinical-stage biopharmaceutical company focused on developing and commercializing the next-generation of innovative therapeutics that aim to improve and address significant unmet medical need for patients with inflammatory, rare-specialty diseases and cancer.
The patent granted by the USPTO covers claims for the Company’s potent Thailanstatin payload platform specific to the spliceosome protein, SF3B1. This patent application is a divisional patent of the Company’s R&D toxin portfolio on Thailanstatin, termed PH-1, building on the portfolio of previously issued patents (Patent No. US 10,815,246 B2, and Patent No. US 10,301,319 B2). Grant Patent right for PCT/US2018/051721 family was issued by China National Intellectual Property Administration in Aug 2023, and in Israel in Sept 2023. Corresponding foreign patent applications are pending and currently undergoing examination in PCT countries – Australia, Canada, the European Patent Office, Japan, Mexico, New Zealand, Singapore, and others.
Structure-activity-relationship studies for novel compounds and medicinal chemistry routes for their synthesis are also described. This Patent is an important addition to the intellectual property portfolio surrounding the Company’s ADC technology, and significantly enhances the patent position for both internal and future potential partner programs.
Peak Bio is developing a differentiated Trop2 PH1 ADC and is investigating collaborations for clinical development and/ or commercialization of this asset along with other collaboration opportunities that incorporate our novel payloads.
Stephen LaMond, PharmD, MBA, Peak Bio, Inc. Interim CEO and COO, commented, “We are pleased to announce the grant of our patents in US, China and Israel and the continued progress with our oncology portfolio (ADCs) that incorporate our novel payloads. We believe the strong interest in novel payloads and ADCs in general will continue given the need for novel and differentiated approaches to the treatment of cancers now and in the future.”
Several of the Company’s management team will participate in the various events and activities surrounding the J.P. Morgan 41st Annual Healthcare Conference 2024. The annual J.P. Morgan Healthcare Conference is the largest and most informative event for the global pharmaceutical industry and the investment community. This year, the conference will take place in San Francisco, CA, the United States, on January 8-11. The management team will be available for meetings during this week. Please contact Stephen LaMond, Interim CEO @steve.lamond@peak-bio.com to schedule any meetings.
About Peak Bio, Inc.
Peak Bio, Inc. is a clinical-stage biopharmaceutical company focused on developing the next-generation of therapeutics to treat oncology and inflammatory orphan/rare diseases.
Peak Bio’s lead product candidate, PHP-303, is a 5th generation, small molecule, neutrophil elastase inhibitor currently awaiting initiation of a Phase II clinical study in the genetic orphan disease called Alpha1 anti-trypsin deficiency disorder (AATD). Peak Bio has successfully completed two Phase 1 clinical studies in human subjects: a single ascending dose trial (SAD) and a multiple ascending dose trial (MAD). The SAD and MAD PHP-303 clinical studies demonstrated a favorable safety profile, and a dose was established for Peak Bio’s upcoming clinical trials.
Peak Bio’s cancer platform consists of novel payloads/toxins in conjunction with an antibody-drug conjugate (ADC) platform that seeks to address a growing unmet need in cancer care. Peak Bio’s current ADC approach has a dual mechanism of action that seeks to unite conventional and direct targeting of cancer cells with toxins while also engaging the immune system with the added potential to enhance cancer cell killing. The Peak Bio payload seeks to stimulate the immune system by leaving behind immune memory cells that continue to kill cancer cells following the initial therapeutic intervention even in the absence of further ADC treatments. The potential for immune reengagement when the cancer reoccurs could be an exciting and important advancement in cancer care with this dual mechanistic approach to cancer therapeutics. Peak Bio’s lead payload appears to be a poor substrate for multi-drug resistance (MDR) transporters which is a growing concern in the ADC field.
