Helsinn announces FDA acceptance of IND application for TAS0953/HM06 in Patients with Advanced Solid Tumors with RET Gene Abnormalities

Lugano, Switzerland, June 8, 2020: Helsinn, a Swiss pharmaceutical group focused on building quality cancer care and rare diseases products, today announced that on April 1, 2020 the U.S. Food and Drug Administration (FDA) completed the review of the Investigational New Drug (IND) application for TAS0953/HM06 and released a "Study May Proceed" letter for the Phase 1/2 Study of TAS0953/HM06 in Patients with Advanced Solid Tumors with RET Gene Abnormalities.

The study is intended to be conducted globally and is due to commence in the third quarter of 2020.

TAS0953/HM06 is being developed together with its partner Taiho Pharmaceutical Co., Ltd.  In 2017, Helsinn and Taiho signed a global co-development and commercialization agreement for TAS0953/HM06.

TAS0953/HM06 is an investigational oral treatment which inhibits several RET abnormalities identified as oncogenic driver alterations in NSCLC, papillary and medullary thyroid cancers, and several other tumor types. This innovative drug candidate offers several differentiating features as compared to other RET inhibitors.

Sergio Cantoreggi, Group Chief Scientific Officer and Head of R&D at Helsinn, commented: “Helsinn and Taiho have been working closely together as part of a global development partnership and we’re delighted to have reached this latest milestone that will allow us to start treating patients with TAS0953/HM06 in a Phase 1/2 clinical trial starting in the next quarter. We are excited by the potential of TAS0953/HM06 to treat NSCLC and other tumors which harbor RET abnormalities and look forward to working with Taiho to progress the treatment through the clinic.”

TAS0953/HM06 is an investigational agent and is not approved for commercial use in any country.

About TAS0953/HM06

TAS0953/HM06 is an oral RET inhibitor in development for advanced or metastatic Non-Small Cell Lung Cancer (NSCLC) and other tumors which express RET gene abnormalities. Preclinical data showed several differentiating features in comparison to other targeted therapies acting on RET abnormalities.

Taiho and Helsinn signed a co-development and commercialization agreement for TAS0953/HM06 in 2017 and will continue to pursue together all preclinical, clinical and CMC developments. This alliance also includes efforts to reach as many patients as possible around the world through their own commercial infrastructures or through valued partners.

About RET abnormalities in NSCLC and other cancers1

RET kinase abnormalities have been identified as targetable oncogenic drivers in NSCLC, papillary and medullary thyroid cancers, and several other tumor types. In NSCLC, RET fusions are more common in younger patients with no prior history of smoking and in those with adenocarcinomas, however the underlying mechanisms remain unknown.
