New York, New York, UNITED STATES


PARAMUS, N.J. and CHENGDU, China, March 01, 2021 (GLOBE NEWSWIRE) -- Starton Therapeutics Inc. (Starton), a US-based privately held clinical-stage biopharmaceutical company, and Haisco Pharmaceutical Group Co., Ltd. (Haisco), a leading China-based pharmaceutical company, announced today that they have entered into an exclusive licensing agreement for the development and commercialization of STAR-OLZ, a once-weekly transdermal olanzapine delivery system in development for Nausea and Vomiting, in Mainland China.

Starton and Haisco are preparing to launch clinical studies in chemotherapy induced nausea and vomiting (CINV), followed by additional nausea and vomiting indications. Starton has completed a human bioavailability study with STAR-OLZ, which successfully delivered therapeutic blood levels and displayed acceptable tolerability.

Pedro Lichtinger, CEO of Starton Therapeutics, commented, “Haisco is an ideal partner for our STAR-OLZ product. In addition to being a respected pharmaceutical company in China, Haisco leads in antiemetic sales in China and has several antiemetics products in the market and in development. Their knowledge and commercial presence in the most price sensitive market will maximize the potential value that STAR-OLZ brings to patients.”

Junmin Wang, Chairman of Haisco Board, commented, “Haisco has built a strong profile in tumor antiemetic area. Our Dolasteron injectable shares a great portion in the antiemetic market in China. In-licensing STAR-OLZ to China brings a more effective and convenient treatment option to Chinese cancer patients and adds on a novel means to differentiate our present antiemetic offerings. We look forward to closely collaborating with Starton to efficiently develop this product to benefit patients as soon as possible.”

Under the terms of the agreement, Starton will receive an undisclosed upfront cash payment and is eligible to receive additional development and regulatory milestone payments, plus double-digit royalties on annual net sales of STAR-OLZ in the territory. Haisco will be responsible for developing and commercializing STAR-OLZ in China.

YAFO Capital (Shanghai) and LifeSci Partners acted as transaction advisors on this transaction.

About STAR-OLZ (olanzapine transdermal delivery system):

STAR-OLZ is a once-weekly transdermal delivery system (TDS) in development for chemotherapy induced nausea and vomiting (CINV) and PARP inhibitor induced nausea and vomiting (PIINV).

STAR-OLZ has completed a human bioavailability study in 36 healthy volunteers. In this study, it was found that STAR-OLZ delivers target therapeutic levels of olanzapine over 7 days, is well-tolerated to the skin, adheres to the skin over the dosing interval with easy removal, and has lower overall sedation side effect intensity when compared to ZYPREXA oral. All endpoints and objectives of the study were met.

Multiple randomized controlled studies have shown olanzapine is superior in control of nausea and non-inferior in control of vomiting versus the standard of care NK1 receptor antagonist in CINV prophylaxis. NCCN guidelines recommend olanzapine for CINV, but the current OLZ label has no nausea and vomiting (NV) indications.

PARP inhibitors are a long-term cancer therapeutic which cause nausea in over 70% of patients. There is no antiemetic approved for use in PIINV. STAR-OLZ is in development to be the first product approved for PIINV.
