Innovent Provides Update on ctDNA in Predicting Response and Resistance by Anti-PD-1 Therapy in Chinese Relapsed/Refractory Classical Hodgkin Lymphoma

SUZHOU, China, June 3, 2019 /PRNewswire/ -- Innovent Biologics, Inc. (Innovent) (HKEX: 01801), a world-class biopharmaceutical company that develops and commercializes high quality medicines, today announced that the results of circulating tumor DNA (ctDNA) for predicting response and resistance by anti-PD-1 therapy in Chinese relapsed/refractory classical Hodgkin lymphoma (r/r cHL) were presented by poster at the 55th Annual Meeting of the American Society of Clinical Oncology (ASCO) [Abstract #7534; Monday, June 3, 8:00 AM -11:00 AM CDT].

As the top and most influential international oncology conference, ASCO Annual Meeting provides the most important platform for publishing and discussing cutting edge clinical studies. Under the theme "Caring for Every Patient, Learning from Every Patient", 2019 ASCO Annual Meeting has attracted numerous top oncologists, scholars, staff from regulatory and patient organizations to share the latest updates and achievements in clinical oncology, with the ultimate goal to help deliver more promising medicines and treatment options to cancer patients.

It is worth noting that more and more Chinese companies choose to participate and disclose their programs in ASCO, showcasing the importance of emerging Chinese biotech industry. As a leading Chinese biotech company, Innovent will provide key result update of several clinical studies at the ASCO 2019 Annual Meeting. The results on the treatment of relapsed or refractory extranodal NK/T cell lymphoma (ORIENT-4) with sintilimab will be presented in an oral session, and key data from several other clinical studies will be presented by posters and other sessions.

Tyvyt® (sintilimab injection), a type of immunoglobulin G4 monoclonal antibody, has been granted approval for market authorization by the National Medical Products Administration of China ("NMPA") for the treatment of patients with relapsed or refractory classical Hodgkin's lymphoma (r/r cHL) based on the clinical data from ORIENT-1 study. A total of 192 plasma samples were collected from 75 patients prior to treatment and during therapy for performing ctDNA extraction next-generation sequencing. To date, ORIENT-1 is the largest study for patients with r/r cHL in China. 

This research, led by Professor Yuan-kai Shi, Associate Dean of the Cancer Hospital of the Chinese Academy of Medical Sciences and Director of the Department of Oncology, is based on ORIENT-1 study, investigates the predictive value of ctDNA from patients with r/r cHL. The study showed:

  • Prior to treatment, the genomic profiling of baseline ctDNA revealed a mean allele mutation frequency of 3.15% (range: 0.49 ~ 60.15). Truncating mutations of B2M, TNFRSF14 and KDM2B were found in patients with acquired resistance: TNFRSF14 and KDM2B have not been previously reported and need to be confirmed in further studies.
  • The baseline ctDNA level was significantly different between the objective response group (CR+PR, n=41) with median baseline ctDNA level of 8.72% and the non-responder group (SD+PD, n=9) (p=0.0070) with median baseline ctDNA level of 2.9%.
  • Patients with ctDNA high achieved first response earlier than others (p<0.05). Patients with ctDNA drop ≥40% after three cycles of therapy achieved first response significantly earlier (median=71 days) than others (median=216 days, p=0.0074).

From this study ctDNA could be a promising predictive biomarker for patients with r/r cHL in China.

Innovent intends to further investigate the clinical value of ctDNA in predicting response and resistance by anti-PD-1 therapy in Chinese r/r cHL. The study demonstrated the ctDNA could serve as valuable biomarker for prediction of r/r cHL patients' response or resistance to anti-PD1 immunotherapy, and might be used to identify patients with genes related to early remission or acquired resistance.

About Tyvyt® (sintilimab injection)

Tyvyt® (sintilimab injection) is an innovative drug jointly developed in China by Innovent and Eli Lilly and Company. Innovent is also conducting clinical studies of sintilimab injection in the United States. Tyvyt® (sintilimab injection) is a type of immunoglobulin G4 monoclonal antibody, which binds to PD-1 molecules on the surface of T-cells, blocks the PD-1/ PD-1 Ligand-1 (PD-L1) pathway and reactivates T-cells to kill cancer cells. Tyvyt® (sintilimab injection) is the only PD-1 antibody in China branded by both a local biopharmaceutical company and a global pharmaceutical company. Tyvyt® (sintilimab injection) has been granted marketing approval by the National Medical Products Administration (NMPA) for relapsed or refractory classical Hodgkin's lymphoma (r/r cHL) and has been included in the 2019 Guidelines of Chinese Society of Clinical Oncology (CSCO) for Lymphoid Malignancies. There are currently more than twenty clinical studies using sintilimab injection, including eight registration studies that evaluate the efficacy of sintilimab injection in other solid tumors.
