Ranok Therapeutics Announces Agreement with Pfizer on Targeted Protein Degradation
Ranok Therapeutics Co. Ltd., an emerging biopharmaceutical company focused on developing breakthrough therapies for cancer and other serious diseases, announced an agreement with Pfizer Inc. to apply and evaluate Ranok’s CHAMP™ platform technology on an undisclosed cancer target. Terms of the agreement were not disclosed.

Ranok has developed a proprietary and innovative targeted protein degradation (TPD) platform technology, CHAMP™ (Chaperone-mediated Protein Degradation), which leverages Ranok’s founders’ expertise in protein homeostasis to take advantage of the cellular chaperone network, potentially improving drug safety and efficacy due to selective targeting of disease tissues.

We are very pleased to work with Pfizer to explore the application of CHAMP™ to an emerging cancer drug target, This represents our first pharmaceutical company research relationship and is an important step forward in establishing CHAMP™ as a preferred technology in the rapidly-growing field of targeted protein degradation. We look forward to uncovering new benefits of CHAMP™ through this research.”

Kevin P. Foley, Ph.D., Co-founder and Chief Scientific Officer of Ranok Therapeutics

This evaluation agreement builds upon Ranok’s recent momentum, including its $40 million Series B financing in August 2021.

KYAN Therapeutics Exclusively Licenses Small Molecule HDAC Inhibitors for AI-Powered Cancer Drug Development

KYAN Therapeutics, Inc. | September 24, 2020

KYAN Therapeutics, Inc. ("KYAN"), a frontier biotech company with a novel drug-dose combination optimizing platform, Optim.AI, has entered into an exclusive license agreement with Georgetown University for novel selective Class II HDAC inhibitors. KYAN has already commenced preclinical development of the lead candidate, which has been designated as KYAN-001, with early positive results. In vitro and in vivo studies of KYAN-001 have shown high efficacy for Multiple Myeloma and Prostate Cancer. The low toxicity and metabolic stability of KYAN-001 indicates a better safety and tolerability profile than FDA approved pan-HDAC inhibitors which suffer from toxicity issues and side effects. KYAN-001 also uniquely inhibits HDAC4 nucleoshuttling to further drive its anti-cancer effects.

Harrow Health Acquires Ophthalmic Surgical Drug Candidate From Wakamoto Pharmaceutical Co., Ltd.

Harrow Health, Inc. | August 18, 2021

Harrow Health, Inc. an ophthalmic‑focused healthcare company, today announced that it has entered into an agreement with Wakamoto Pharmaceutical Co., Ltd. to acquire the U.S. and Canadian commercial rights for drug candidate MAQ-100, a preservative-free triamcinolone acetonide ophthalmic injection. MAQ-100 is marketed and sold by Wakamoto in Japan as MaQaid®. Following Japan’s Ministry of Health Labor and Welfare (or MHLW) approval, MaQaid was launched in Japan in 2010, indicated as an intravitreal injection for visualization for vitrectomy. Since its initial MHLW approval, the indication for MaQaid was expanded to include (a) treatments for alleviation of diabetic macular edema, (b) macular edema associated with retinal vein occlusion (or RVO), and (c) non‑infectious uveitis. Harrow intends to leverage the clinical data used for Japanese market approval of MaQaid, initially to support a clinical program and U.S. market NDA submission of MAQ-100 for visualization during vitrectomy. Mark L. Baum, CEO of Harrow Health, stated, “We are indeed honored to work with our new partners at Wakamoto to bring MAQ-100 to the U.S. and Canadian markets. This transaction is an excellent strategic fit with our recent commitment to expand our footprint to include retina‑focused surgeons and follows our recent announcement of the acquisition of AMP‑100, a patented, innovative ocular surface anesthetic drug candidate. Both transactions represent progress towards the execution of our strategic goal to grow Harrow through the addition of high-value products to our pharmaceutical portfolio. And both transactions allow us to leverage our wholly owned, efficient, scalable, and tech‑enabled ImprimisRx ophthalmic-focused platform to expand the portfolio of ophthalmic pharmaceutical products we provide to the thousands of prescribers we serve across the country.” Norihisa Kojima, CEO for Wakamoto Pharmaceuticals, stated, “We are very glad to have an opportunity to collaborate with Harrow Health. We believe Harrow Health’s exclusive focus on ophthalmology and commitment to thousands of American ophthalmic surgeons, providing high‑quality and innovative medications, make Harrow an excellent selection for potential expansion to the U.S. and Canada markets.” Under the terms of the agreement, Wakamoto will receive payments based on the achievement of commercial milestones and supply Harrow with MAQ-100. Harrow Health will have marketing rights for the U.S. and Canada, while Wakamoto Pharmaceuticals will retain MAQ-100 marketing rights in other countries. B.
