The phase Ib/II clinical trial expected to start in the first quarter of 2026 is designed to evaluate the safety, tolerability, pharmacokinetics, and preliminary antitumor activity of atamparib in patients with advanced solid tumors, with a focus on a promising new therapeutic sub-setting. The goal is to validate the molecule’s differentiated mechanism of action and its favorable safety and tolerability with more than 200 patients treated so far, both in late-line patients and in future combination with standard-of-care in earlier treatment settings.
"The IND approval in China represents a key strategic milestone for the development of atamparib," said Hugues Dolgos, CEO of NMS Srl. "Recent data generated across preclinical and clinical programs, along with the newly published mechanism of action, have enabled us to reposition this asset into a promising sizeable indication where we believe it can deliver meaningful clinical benefit."
"Conducting the study in China is expected to support atamparib global clinical development by enabling timely access to a clinically relevant patient population and facilitating the potential availability of new treatment options for patients in China and worldwide," said Dadong Li, CEO of NMS Shanghai. "This milestone marks an important step in advancing the development of atamparib and exploring its potential to expand treatment options for patients."
In parallel, NMS is advancing a dual inhibitor program currently in preclinical development, targeting PARP7 and another undisclosed target, which is expected to complement the clinical development strategy of atamparib and underscores the company’s commitment to building a differentiated portfolio of innovative therapeutic candidates.
