On September 6, 2022 InnoCare Pharma (HKEX: 09969), a leading biopharmaceutical company for the treatment of cancer and autoimmune diseases, reported that BTK inhibitor orelabrutinib has been granted priority review for the treatment of relapsed or refractory Marginal Zone Lymphoma (R/R MZL) by the Center for Drug Evaluation (CDE) of the China National Medical Products Administration (NMPA), which accepted the supplemental New Drug Application (sNDA) of orelabrutinib for the treatment of R/R MZL recently (Press release, InnoCare Pharma, SEP 6, 2022, View Source [SID1234618999]).

Dr. Jasmine Cui, Co-founder, Chairwoman and CEO of InnoCare said: "We are so inspired by this excited news. This is the third indication of orelabrutinib granted priority review. There are unmet medical needs for patients with R/R MZL. We hope orelabrutinib can bring better treatment options to benefit patients with R/R MZL."

The sNDA of Orelabrutinib for the treatment of R/R MZL was accepted by the CDE on August 12. This NDA was submitted based on data from an open multi-center Phase II clinical study to investigate the safety and efficacy of orelabrutinib for the treatment of R/R MZL.

Current treatment options for R/R MZL are quite limited. So far, no BTK inhibitor has ever been approved for treating patients with R/R MZL in China, and hope that orelabrutinib can fill the gap in this therapeutic area.

About Orelabrutinib

Orelabrutinib is a highly selective BTK inhibitor developed by InnoCare for the treatment of cancers and autoimmune diseases.

On Dec. 25 2020, orelabrutinib received conditional approval from the China National Medical Products Administration (NMPA) in two indications: the treatment of patients with relapsed/refractory chronic lymphocytic leukemia (CLL) /small lymphocytic lymphoma (SLL), and the treatment of patients with relapsed/refractory mantle cell lymphoma (MCL). At the end of 2021, orelabrutinib was included into National Reimbursement Drug list to benefit more lymphoma patients.

In addition to the approved indications, multi-center, multi-indication clinical trials are underway in the US and China with orelabrutinib as monotherapy or in combination therapies.

Orelabrutinib was granted as Breakthrough Therapy Designation for the treatment of r/r MCL by U.S. Food and Drug Administration (FDA).

In addition, orelabrutinib is also being evaluated in global phase II studies for the treatment of Multiple Sclerosis (MS), and clinical trials for the treatment of SLE, Primary Immune Thrombocytopenia (ITP) and Neuromyelitis Optica Spectrum Disorder (NMOSD) in China.

On September 5, 2022 OSE Immunotherapeutics SA (ISIN: FR0012127173; Mnemo: OSE) reported the presentation of two new analyses from the Phase 3 Atalante-1 study of immunotherapy Tedopi, in patients with advanced non-small cell lung cancer (NSCLC) in secondary resistance after failure of previous checkpoint inhibitor treatments, at the 2022 European Society for Medical Oncology (ESMO) (Free ESMO Whitepaper) Congress, being held September 9-13, in Paris (Press release, OSE Immunotherapeutics, SEP 5, 2022, View Source [SID1234646962]).

Alexis Vandier, Chief Executive Officer of OSE Immunotherapeutics, commented: "In patients with no treatment option after failure of two therapeutic classes, in particular post-checkpoint inhibitors, Tedopi has shown an overall clinical benefit in this phase 3 study, integrating both efficacy and tolerance compared to chemotherapy treatments. This new specific immunotherapy offers prospects for therapeutic management, both in monotherapy and in combination, and we will do our best to make this treatment available as soon as possible for these patients."

The first analysis compared Tedopi to the Standard of Care (SoC) in patients with advanced NSCLC after secondary resistance to sequential use of chemotherapy followed by immunotherapy (CT-IO).

The results have shown that in advanced HLA-A2+ NSCLC patients with IO secondary resistance after sequential CT-IO (n=118), overall survival (OS) was longer with Tedopi versus SoC regardless of the use (or not) of post progression anticancer treatment (with 13.5 months versus 10.6, HR=0.71; without 6.3 months versus 4.5, HR=0.76).

This analysis will be presented by Dr Maria Rosario Garcia Campelo (Head of Medical Oncology Department, Thoracic Tumors Unit, Investigator of Atalante-1 study, University Hospital A Coruña, Spain).

Dr Garcia Campelo said: "There is a strong medical need for a new therapeutic alternative in these heavily pretreated NSCLC patients, aiming not only at a prolonged survival but desiring a maintained global health status."

The second analysis assessed the overall benefit/risk of Tedopi versus SoC chemotherapy in patients with NSCLC who failed therapy with immune checkpoint inhibitors. The Net Treatment Benefit (NTB)*, a new statistical method combining efficacy, safety and quality of life, was assessed in the overall population (n=219). NTB of Tedopi was of 19% and reached statistical significance (p=0.035).

This analysis will be presented by Dr Marc Buyse, (Founder and Chief Scientific Officer, International Drug Development Institute (IDDI), Brussels, Belgium).
