Florence, Italy and New York (ots/PRNewswire) – Menarini Group (“Menarini”) is a leading international manufacturer of pharmaceuticals and diagnostic products, Stemline Therapeutics, Inc. (“Stemline”) a wholly owned subsidiary of Menarini Group, dedicated to helping cancer patients with transformative oncology therapies. Together with Insilico Medicine (“Insilico”), a generative artificial intelligence (AI)-powered clinical-stage drug discovery biotechnology company, the companies today announced that Stemline has received an exclusive license agreement for worldwide rights to develop and commercialize a new small molecule KAT6A inhibitor using Insico’s AI platform, which could be a treatment option for hormone-sensitive cancers and other oncological indicators.
- KAT6 is a novel target in hormone-sensitive breast cancer tumors and other cancers. Overexpression of KAT6A/B is associated with poor clinical outcomes in patients with ER+/HER2- breast cancer, one of the most common subtypes.
- The molecule showed high preclinical activity. Insilico presented data on this new molecule at the San Antonio Breast Cancer Symposium in early December.
- The agreement includes upfront and milestone payments with a total potential of over $500 million, as well as royalties.
Breast cancer is one of the most commonly diagnosed tumor types and is a leading cause of cancer-related deaths in women worldwide.(1) Approximately 70% of breast cancer tumors are estrogen receptor positive (ER+). Endocrine therapy is and remains the treatment of choice for ER+ breast cancer. However, tumors can develop resistance to endocrine therapy, which can lead to worsening of the disease. This is a major clinical challenge and shows how important it is to develop new forms of therapy that can overcome treatment resistance.
KAT6A plays an important role in many types of cancer. Overexpression of KAT6A is associated with poor clinical outcomes in patients with ER+/HER2- breast cancer, one of the most common subtypes. In preclinical studies, the molecule demonstrated potent inhibition of KAT6A in multiple CDX and PDX models with good efficacy and safety. Insilico presented data on this molecule at the San Antonio Breast Cancer Symposium in early December.
“We look forward to working with Insilico. “It gives us as a leading company the opportunity to use generative AI to explore a promising new treatment approach and develop potentially transformative new cancer therapies,” said Elcin Barker Ergun, CEO of Menarini Group. “With Elacestrant, we have in the US and Europe After almost 20 years, the first innovation in endocrine therapy for ER+ and HER2- breast cancer patients has been brought onto the market. Our goal is to further improve the treatment results of patients. KAT6A as a target can prove to be extremely effective not only in breast cancer. “
The new molecule was developed by the R&D team at Insilico using a pharmaceutical-specific generative AI platform to inhibit KAT6A and block the endocrine receptor (ER) at the transcription level. This opens up the opportunity to overcome resistance to endocrine therapies that can develop due to mutations or ligand-independent constitutive activation of ER. Currently, endocrine therapy in combination with CDK4/6 inhibitors is considered the standard treatment for ER+/HER2- breast cancer patients with advanced metastases. New combinations with CDK4/6 inhibitors and/or new orally administered SERDs are required to further expand on the results.
“Our latest therapy developed using generative AI is very promising. It could represent a new treatment option for breast cancer patients,” explains Dr. Alex Zhavoronkov, founder and co-CEO at Insilico Medicine. “With its innovative vision and focus on transformative oncology therapies, Stemline is the ideal partner to further develop this molecule and through the clinical trials.”
As part of the agreement, Stemline will pay Insilico $12 million up front. The total value of the agreement, including all development, regulatory and commercial milestones, is over $500 million, followed by double-digit royalties.
