EQRx Announces Acceptance of Marketing Authorization Application by the UK’s Medicines and Healthcare Products Regulatory Agency for Sugemalimab in Metastatic Non-small Cell Lung Cancer

• Application is based on data from the pivotal Phase 3 GEMSTONE-302 trial assessing sugemalimab in combination with chemotherapy as first-line treatment of metastatic non-small cell lung cancer
• Acceptance of the marketing authorization application (MAA) is EQRx’s second from the United Kingdom’s Medicines and Healthcare products Regulatory Agency after acceptance of aumolertinib MAA earlier this year

CAMBRIDGE, Mass., Dec. 19, 2022 (GLOBE NEWSWIRE) — EQRx, Inc. (Nasdaq: EQRX), a new type of pharmaceutical company committed to developing and expanding access to innovative medicines for some of the most prevalent disease areas, including cancer and immune-inflammatory conditions, today announced that the United Kingdom’s (U.K.) Medicines and Healthcare products Regulatory Agency (MHRA) has accepted for review its marketing authorization application (MAA) for sugemalimab, an anti-programmed death-ligand 1 (PD-L1) antibody, in combination with chemotherapy for the first-line treatment of adult patients with metastatic non-small cell lung cancer (NSCLC).

“With the acceptance of this application, we now have two investigational therapies under review with the MHRA in non-small cell lung cancer, which affects about 40,000 people annually in the U.K. and is a leading cause of cancer death,” said Melanie Nallicheri, president and chief executive officer of EQRx. “This significant milestone is a step toward our goal of getting our medicines to patients and delivering on our mission of increasing access to impactful treatments.”

The MAA is primarily supported by data from the pivotal Phase 3 GEMSTONE-302 trial, conducted by EQRx’s partner CStone Pharmaceuticals, that evaluated treatment with sugemalimab in combination with chemotherapy in patients with metastatic NSCLC.

In 2021, sugemalimab was granted the Innovation Passport designation in the U.K. through the Innovative Licensing and Access Pathway (ILAP) from the ILAP partner organizations including the MHRA. The ILAP was established in early 2021 to accelerate the development of and access to medicines in the U.K.

About Sugemalimab
Sugemalimab is a monoclonal antibody targeting programmed death-ligand 1 (PD-L1) that is under investigation in several ongoing clinical trials, including studies in relapsed or refractory extranodal natural killer/T cell lymphoma (ENKTL), Stage III non-small cell lung cancer (NSCLC), Stage IV NSCLC, gastric cancer and esophageal cancer. In October of 2020, the U.S. Food and Drug Administration (FDA) granted sugemalimab Breakthrough Therapy designation for the treatment of adult patients with relapsed or refractory ENKTL. Sugemalimab is approved by the National Medical Products Administration (NMPA) of China for the treatment of patients with unresectable Stage III NSCLC whose disease has not progressed following concurrent or sequential platinum-based chemoradiotherapy and in combination with chemotherapy for the first-line treatment of patients with metastatic squamous and non-squamous NSCLC. Sugemalimab was discovered by CStone Pharmaceuticals, and EQRx has partnered with CStone Pharmaceuticals on the global development of sugemalimab with the goal of expanding access worldwide. EQRx holds the development and commercialization rights to sugemalimab outside of Greater China.

About GEMSTONE-302
GEMSTONE-302 (NCT03789604) is a randomized, double-blind, Phase 3 study designed to evaluate the efficacy and safety of sugemalimab versus placebo in combination with carboplatin-based chemotherapy as a first-line treatment for patients with Stage IV squamous or non-squamous non-small cell lung cancer (NSCLC). The study was conducted by CStone Pharmaceuticals and included 479 patients who were randomized to either the sugemalimab group (n=320) or the placebo group (n=159). The study met its primary endpoint, demonstrating statistically significant improvement in investigator-assessed progression-free survival (PFS) with sugemalimab plus chemotherapy compared to placebo plus chemotherapy.¹ Secondary endpoints include overall survival, PFS in patients with PD-L1 ≥1% (assessed by the investigators), PFS as assessed by blinded independent central review (BICR), objective response rate (assessed by the investigators), duration of response and safety. In 2022, results from GEMSTONE-302 were published in The Lancet Oncology and favorable data on overall survival, a pre-specified secondary endpoint, were presented at the 2022 American Society of Clinical Oncology (ASCO) Annual Meeting.^1,2
