Zai Lab and Novocure Achieve Landmark Results in Cancer Trial

Collaboration Between Zai Lab and Novocure

Zai Lab Limited (NASDAQ: ZLAB; HKEX: 9688) and Novocure (NASDAQ: NVCR) have made headlines with their recent announcement regarding the pivotal PANOVA-3 trial. This Phase 3 clinical trial has successfully met its primary endpoint, showcasing a statistically significant improvement in median overall survival (mOS) for patients treated with Tumor Treating Fields (TTFields) therapy, alongside traditional chemotherapy options.

A Closer Look at the PANOVA-3 Trial

The PANOVA-3 trial evaluated the combination of TTFields therapy with gemcitabine and nab-paclitaxel as a frontline treatment for patients suffering from unresectable, locally advanced pancreatic adenocarcinoma. The results have been encouraging, highlighting the potential of TTFields therapy in improving patient outcomes in this challenging clinical setting.

Impressive Survival Rates

In the intention-to-treat population, those receiving the combination of TTFields therapy, gemcitabine, and nab-paclitaxel experienced an mOS of 16.20 months, a significant improvement over the 14.16 months observed in patients receiving only chemotherapy. This equates to a notable enhancement of 2.0 months, accompanied by a 13% overall improvement in survival rates at the one-year mark, and a remarkable 33% improvement at two years. Furthermore, the therapy was well-tolerated, demonstrating a safety profile consistent with earlier clinical findings.

Expert Insights on the Trial

Dr. Vincent Picozzi, a leading medical oncologist involved in the trial, expressed his enthusiasm for the outcomes, emphasizing the pivotal nature of achieving such results in pancreatic cancer. He stated that the data from PANOVA-3 provide hope for patients in this difficult-to-treat population, marking a significant milestone in oncological research.

Future Implications for Treatment

Dr. Nicolas Leupin, M.D., PhD, Chief Medical Officer of Novocure, highlighted the significance of PANOVA-3 as the sole Phase 3 trial exhibiting a statistically meaningful benefit in overall survival for this specific patient demographic. Both companies are eager to present the full results at an upcoming medical conference and to proceed with regulatory filings for TTFields therapy.

About the Growing Need for Effective Therapies

With approximately 134,000 new pancreatic cancer cases diagnosed annually in certain markets, it’s increasingly recognized as one of the most formidable cancers to treat. Dr. Rafael Amado, President of Global Research and Development at Zai Lab, noted that the standard treatment options often yield poor survival rates, making PANOVA-3's outcomes particularly invaluable.

Understanding Tumor Treating Fields Therapy

Tumor Treating Fields (TTFields) represent a cutting-edge therapeutic approach using electric fields to target and destroy cancer cells without significantly impacting healthy cells. The mechanisms of TTFields therapy allow for its integration with various treatment modalities, such as chemotherapy and radiotherapy, enhancing its effectiveness across numerous solid tumor types.

Continued Research and Development

Zai Lab and Novocure are committed to advancing the potential of TTFields therapy. Both companies are actively involved in additional clinical trials exploring its effectiveness in other cancer types, including glioblastoma and non-small cell lung cancer. This dedication to innovation underscores their mission to combat some of the most aggressive cancers.

Company Profiles

Zai Lab Limited focuses on creating a wide array of innovative biopharmaceutical products that target pressing medical needs in oncology, among other fields. Their collaboration with Novocure positions them at the forefront of exciting cancer treatment advancements.

On the other hand, Novocure specializes in therapies intended to extend survival for patients with challenging cancers, standing out with its commercialized products approved for various indications. Their ongoing commitment to research in TTFields therapy showcases their proactive approach in the fight against cancer.
