TG Therapeutics Rolling NDA for Lymphoma Drug
TG Therapeutics has begun a rolling NDA submission for umbralisib, an oral, once-daily, dual inhibitor of PI3K-delta and CK1-epsilon for treating patients with previously treated marginal zone lymphoma (MZL) and follicular lymphoma (FL). The company says it has requested accelerated approval after receiving guidance from the agency that it was acceptable to file a single NDA for both the MZL and FL indications. It expects to complete the submission by 7/1.
It is based on data from the company’s UNITY-NHL Phase 2 study. TG Therapeutics says the MZL cohort was designed to evaluate the safety and efficacy of single agent umbralisib in patients with MZL who have received at least one prior anti-CD20 regimen. The primary endpoint is overall response rate. The FL cohort was designed to evaluate single agent umbralisib in patients with FL who have received at least two prior lines of therapy, including an anti-CD20 regimen and an alkylating agent. The primary endpoint is also overall response rate.
