"We are pleased to collaborate with MSD to evaluate nemvaleukin in combination with KEYTRUDA in patients with platinum-resistant ovarian cancer, a patient population for which there are limited treatment options available and overall survival remains low. Importantly, there are no anti-PD-1 treatments currently approved for this tumor type," said Jessicca Rege, Ph.D., Vice President, Head of Oncology at Alkermes. "Nemvaleukin in combination with KEYTRUDA has demonstrated antitumor activity in heavily pre-treated patients with platinum-resistant ovarian cancer in the ongoing ARTISTRY-1 study, with durable and deepening responses observed. We look forward to initiating this phase 3 study to further evaluate the potential clinical utility of this combination in this tumor type and advancing our interactions with regulatory authorities related to potential registration strategies for the combination in platinum-resistant ovarian cancer."

About nemvaleukin alfa
Nemvaleukin is an investigational, novel, engineered fusion protein comprised of modified interleukin-2 (IL-2) and the high affinity IL-2 alpha receptor chain, designed to selectively expand tumor-killing immune cells while avoiding the activation of immunosuppressive cells by preferentially binding to the intermediate-affinity IL-2 receptor complex. The selectivity of nemvaleukin is designed to leverage the proven antitumor effects of existing IL-2 therapy while mitigating certain limitations.

About the ARTISTRY Clinical Development Program
ARTISTRY is an Alkermes-sponsored clinical development program evaluating nemvaleukin in patients with advanced solid tumors.

ARTISTRY-1 and ARTISTRY-2 are phase 1/2 studies evaluating the safety, tolerability, efficacy and pharmacokinetic and pharmacodynamic effects of nemvaleukin in patients with refractory advanced solid tumors, in both monotherapy and combination settings with the PD-1 inhibitor pembrolizumab (KEYTRUDA). In ARTISTRY-1, nemvaleukin is administered as an intravenous infusion daily for five consecutive days, followed by an off-treatment period. In the ongoing phase 2 efficacy expansion stage of ARTISTRY-2, nemvaleukin is administered subcutaneously once every seven days.

ARTISTRY-3 is a phase 2 study evaluating the clinical and immunologic effects of intravenous nemvaleukin monotherapy on the tumor microenvironment of a variety of advanced, malignant solid tumors.

"The addition of our Elecsys Anti-p53 immunoassay will help clinicians to quickly and reliably diagnose several prevalent cancers and might assist in leading to a better prognosis for many patients.", said Thomas Schinecker, CEO Roche Diagnostics. "Beyond breakthrough cancer medicines, Roche also offers a growing number of testing solutions to help physicians diagnose and treat people with cancer.

p53 is protein which, when active, helps to regulate processes which stop tumors from developing. A mutation of p53 is present in half of solid tumor cancers and is the most common genetic change identified so far in human cancers.1 Certain mutations of p53 can lead to a build up of p53 which results in the formation of anti-p53 autoantibodies. Autoantibodies are antibodies that mistakenly target and react with a person’s own tissues. Between 20-50% of patients with mutated p53 will produce anti-p53 autoantibodies.2 This mutation causes the tumor suppressive function of p53 to switch to a tumor-promoting function and thus cancer development.

Early appearance of anti-p53 antibodies during tumour development may have potential to detect malignant changes.3 The Elecsys Anti-p53 immunoassay detects these anti-p53 antibodies and, when used with other diagnostic tests, can help to diagnose certain cancers, at an earlier stage, which may help to improve patient outcomes. Determining the presence of anti-p53 antibodies may also be useful for monitoring cancerous cells that are still in the body following treatment.4 In addition, the Elecsys Anti-p53 test could aid in determining which patients may require less invasive treatment procedures, as part of their cancer treatment.

About Elecsys Anti-p53

"We started building this large-scale, commercial biologics manufacturing facility in 2017 to meet our expected future demand. Since that time, tislelizumab has been approved in several indications in China, included in the National Reimbursement Drug List (NRDL), and licensed to Novartis in Europe, North America, and Japan," commented Xiaobin Wu, Ph.D., President, Chief Operating Officer, and General Manager of China at BeiGene. "With significantly expanded capacity for tislelizumab and for other biologics in our pipeline, we are continuing our strong commitment to the quality, safety, and compliance of our products."

BeiGene’s Guangzhou manufacturing facility has been designed to operate in compliance with current Good Manufacturing Practice (cGMP) standards adopted by the U.S. Food & Drug Administration (FDA), the China National Medical Products Administration (NMPA), and the European Medicines Agency (EMA). The Guangzhou site is expected to be the first paperless biological manufacturing facility in China and integrates new technologies such as 3D modeling, digital twin, augmented interfaces, and artificial intelligence to improve quality and efficiency.

About Tislelizumab

Tislelizumab (BGB-A317) is a humanized IgG4 anti-PD-1 monoclonal antibody specifically designed to minimize binding to FcγR on macrophages. In pre-clinical studies, binding to FcγR on macrophages has been shown to compromise the anti-tumor activity of PD-1 antibodies through activation of antibody-dependent macrophage-mediated killing of T effector cells. Tislelizumab is the first drug from BeiGene’s immuno-oncology biologics program and is being developed internationally as a monotherapy and in combination with other therapies for the treatment of a broad array of both solid tumor and hematologic cancers.

The China National Medical Products Administration (NMPA) has granted tislelizumab full approval for first-line treatment of patients with advanced squamous non-small cell lung cancer (NSCLC) in combination with chemotherapy. Tislelizumab has also received conditional approval from the NMPA for the treatment of patients with classical Hodgkin’s lymphoma (cHL) who received at least two prior therapies, and for the treatment of patients with locally advanced or metastatic urothelial carcinoma (UC) with PD-L1 high expression whose disease progressed during or following platinum-containing chemotherapy or within 12 months of neoadjuvant or adjuvant treatment with platinum-containing chemotherapy. Full approval for these indications is contingent upon results from ongoing randomized, controlled confirmatory clinical trials.

In addition, three supplemental Biologics License Applications for tislelizumab have been accepted by the Center for Drug Evaluation (CDE) of the NMPA and are under review for first-line treatment of patients with advanced non-squamous NSCLC in combination with chemotherapy, for the second- or third-line treatment of patients with locally advanced or metastatic NSCLC who progressed on prior platinum-based chemotherapy, and for previously treated unresectable hepatocellular carcinoma.

Currently, 16 potentially registration-enabling clinical trials are being conducted in China and globally, including 13 Phase 3 trials and three pivotal Phase 2 trials.

In January 2021, BeiGene and Novartis entered into a collaboration and license agreement granting Novartis rights to develop, manufacture, and commercialize tislelizumab in North America, Europe, and Japan.

Tislelizumab is not approved for use outside of China.
