Innovent Announces ORIENT-31, a Phase 3 Study of Sintilimab in Patients with EGFR-Mutated Nonsquamous Non-Small Cell Lung Cancer with Prior EGFR-TKI Treatment, Has Met Primary Endpoint
SAN FRANCISCO and SUZHOU,China,Oct. 18,2021 -- Innovent Biologics,Inc. ("Innovent") (HKEX: 01801),a world-class biopharmaceutical company that develops,manufactures and commercializes high quality medicines for the treatment of oncology,metabolic,autoimmune and other major diseases,today announced that the sintilimab ORIENT-31 study has met its prespecified primary endpoint of progression-free survival (PFS) at the first interim analysis.
Globally,ORIENT-31 is the first prospective,double-blind,multi-center,Phase 3 study that has demonstrated significant PFS improvement of anti-PD-1 and anti-VEGF antibody combination therapy (i.e.,sintilimab plus BYVASDA® [bevacizumab biosimilar injection] combined with chemotherapy [pemetrexed and cisplatin]) in patients with epidermal growth factor receptor (EGFR)-mutated nonsquamous non-small cell lung cancer (nsqNSCLC) that has progressed after treatment with an EGFR tyrosine kinase inhibitor (TKI).
In the first interim analysis reviewed by the Independent Data Monitoring Committee (IDMC),in the intent-to-treat (ITT) population,based on assessment by the Blinded Independent Radiographic Review Committee (BIRRC),sintilimab in combination with BYVASDA® (bevacizumab biosimilar injection) and chemotherapy demonstrated a statistically significant and clinically meaningful improvement in PFS compared with chemotherapy. Sintilimab in combination with chemotherapy also showed a trend of PFS benefit compared to chemotherapy alone (data is not yet mature). Additionally,the prespecified PFS futility analysis that compares sintilimab in combination with BYVASDA® (bevacizumab biosimilar injection) and chemotherapy to sintilimab in combination with chemotherapy did not cross futility stopping boundary. A numerical benefit of adding BYVASDA® (bevacizumab biosimilar injection) to sintilimab and chemotherapy combination can be observed. The safety profile of this study was consistent with that observed in previously reported studies of sintilimab and BYVASDA® (bevacizumab biosimilar injection),with no additional safety signals. The detailed results of ORIENT-31 will be presented at an upcoming medical meeting.
The principal investigator of the ORIENT-31,Prof. Shun Lu from the Oncology Department of Shanghai Chest Hospital,stated,"For patients with EGFR-mutated advanced nsqNSCLC who have progressed following EGFR-TKI treatment,platinum-based chemotherapy is the current standard of care,but with limited benefit. New treatments are clearly imperative. ORIENT-31 is the first prospective,double-blind Phase 3 study worldwide to demonstrate significant PFS benefit with an anti-PD-1 antibody combination therapy in this patient population. It has shown the clinical value of adding sintilimabplusBYVASDA® (bevacizumab biosimilar injection) to platinum chemotherapy. This quadruple regimen has the potential to bring forth a new and more effective treatment option to patients with EGFR-mutated nsqNSCLC following treatment with an EGFR TKI."
Dr. Hui Zhou,Senior Vice President of Innovent,"Lung cancer has the highest mortality rate among all tumor types both in China and worldwide. In China,EGFR-mutated NSCLC accounts for 40% to 50% of nonsquamous NSCLC,and the treatment options for these patients after treatment with first,second and third generation EGFR-TKIs are very limited,representing a large unmet medical need. Through the joint efforts of investigators,ORIENT-31 achieved these encouraging research results. We are grateful for all the contributions made by the investigators and patients in this study – together we accomplished this important milestone."
About Non-Squamous Non-Small Cell Lung Cancer (NSCLC)
Lung cancer is the leading cause of cancer death worldwide,and the second most commonly diagnosed tumor type. Non-small cell lung cancer (NSCLC) accounts for about 80% to 85% of all lung cancer,in which about 70% of NSCLC patients present with locally advanced or metastatic disease that is not suitable for surgical resection at diagnosis. In China,nsqNSCLC accounts for 70% of NSCLC,in which about 40% to 50% of nsqNSCLC patients have an EGFR mutation. The standard first-line treatment for patients with advanced EGFR-mutated NSCLC is a third generation EGFR TKI,or first or second generation EGFR TKI. For patients who have progressed following EGFR-TKI treatment,platinum-based chemotherapy is still the standard therapywith limited benefit,representing a large unmet medical need.
About the ORIENT-31 Study
ORIENT-31 is a randomized,multicenter Phase 3 clinical study evaluating sintilimab,with or without BYVASDA® (bevacizumab biosimilar injection),combined with chemotherapy (pemetrexed and cisplatin) in patients with EGFR-mutated locally advanced or metastatic non-squamous NSCLC who have progressed following EGFR TKI treatment(ClinicalTrials.gov,NCT003802240). The primary endpoint is PFS as assessed by BIRRC based on RECIST v1.1. The secondary endpoints include overall survival (OS),PFS as assessed by investigators,objective response rate (ORR) and safety.
Eligible patients included: patients with disease progression following first or second generation EGFR TKI and confirmed as T790M negative,or T790M positive but further progressed on third generation EGFR-TKI treatment,or patients with disease progression following third generation EGFR-TKI as first line treatment.
Patients were randomized in a 1:1:1 ratio to receive sintilimabplus BYVASDA® (bevacizumab biosimilar injection) combined with pemetrexed and cisplatin,sintilimab plus placebo 2 combined with pemetrexed and cisplatin,or placebo 1 plus placebo 2 combined with pemetrexed and cisplatin. After 4 cycles of combination treatment,patients will receive maintenance treatment of sintilimabplus BYVASDA® and pemetrexed,sintilimabplus placebo 2 and pemetrexed,placebo 1plus placebo 2 and pemetrexed,until radiographic disease progression,unacceptable toxicity or any other conditions that required treatment discontinuation. Target accrual is 480 patients.
About Sintilimab
Sintilimab,marketed as TYVYT® (sintilimab injection) in China,is an innovative PD-1 inhibitor with global quality standards jointly developed by Innovent and Eli Lilly and Company. Sintilimab is an immunoglobulin G4 monoclonal antibody,which binds to PD-1 molecules on the surface of T-cells,blocks the PD-1 / PD-Ligand 1 (PD-L1) pathway,and reactivates T-cells to kill cancer cells. Innovent is currently conducting more than 20 clinical studies of sintilimab worldwide,to evaluate its safety and efficacy in a wide variety of cancer indications,including more than 10 registrational or pivotal clinical trials.
In China,sintilimab has been approved for four indications,including:
The treatment of relapsed or refractory classic Hodgkin's lymphoma after two lines or later of systemic chemotherapy
In combination with pemetrexed and platinum chemotherapy,for the first-line treatment of nonsquamous non-small cell lung cancer
In combination with gemcitabine and platinum chemotherapy,for the first-line treatment of squamous non-small cell lung cancer
In combination with BYVASDA® (bevacizumab biosimilar injection) for the first-line treatment of hepatocellular carcinoma
Additionally,Innovent currently has one regulatory submission under review in China for sintilimab,for the first line treatment of esophageal squamous cell carcinoma.
Additionally,four clinical studies of sintilimab have met their primary endpoints:
Phase 3 study in combination with oxaliplatin and capecitabine for the first-line treatment of unresectable,locally advanced,recurrent or metastatic gastric or gastroesophageal junction adenocarcinoma.
Phase 2 study as second-line treatment of esophageal squamous cell carcinoma
Phase 3 study as second-line treatment for squamous NSCLC with disease progression following platinum-based chemotherapy
Phase 3 study in combination with BYVASDA® (bevacizumab biosimilar injection) and chemotherapy (pemetrexed and cisplatin) for EGFR-mutated nonsquamous NSCLC following EGFR-TKI treatment.
In May 2021,the U.S. FDA accepted for review the Biologics License Application (BLA) for sintilimab in combination with pemetrexed and platinum chemotherapy for the first-line treatment of nonsquamous non-small cell lung cancer.
Sintilimab was included in China's National Reimbursement Drug List (NRDL) in 2019 as the first PD-1 inhibitor and the only PD-1 included in the list in that year.
About BYVASDA® (bevacizumab biosimilar injection)
BYVASDA®,also known as IBI305,is a bevacizumab biosimilar and a recombinant humanized anti-VEGF monoclonal antibody drug. Vascular endothelial growth factor (VEGF) is an important factor in angiogenesis that is highly expressed by the endothelial cells in most human tumors. An anti-VEGF antibody binds VEGF-A selectively with high affinity and blocks its binding to VEGF-2 receptors on the surface of vascular endothelial cells,thereby inhibiting signaling pathways such as PI3K-Akt/PKB and Ras-Raf-MEK-ERK. BYVASDA® produces anti-tumor effects by inhibiting the growth,proliferation and migration of vascular endothelial cells,blocking angiogenesis,reducing vascular permeability,blocking blood supply to tumor tissues,inhibiting the proliferation and metastasis of tumor cells and inducing apoptosis in tumor cells. Since its launch,bevacizumab has been approved for the treatment of patients with multiple malignant tumors globally,including non-small cell lung cancer,metastatic colorectal cancer,glioblastoma,renal cell carcinoma,cervical cancer,and epithelial ovarian,fallopian tube,or primary peritoneal cancer. The efficacy and safety of bevacizumab in these tumor types have been well recognized worldwide.
In China,BYVASDA® (bevacizumab biosimilar injection) is approved for indications including advanced non-small cell lung cancer,adult recurrent glioblastoma,and advanced or unresectable hepatocellular carcinoma.
