"The NMPA’s acceptance of our NDA submission for ZEJULA represents a major milestone for Zai Lab as this is our first ever NDA submission in Mainland China," said Dr. Samantha Du, Founder and Chief Executive Officer of Zai Lab. "ZEJULA will offer an important, new treatment option to more than 50,000 Chinese patients who suffer from ovarian cancer every year and we are grateful that NMPA recognizes this critical medical need and the promise of ZEJULA. Zai is a leader in the field of innovative oncology treatments in China and we have a deep and highly-differentiated pipeline, including three U.S. FDA-approved products and four other assets in late stage clinical development. As a result, we expect additional regulatory submissions in the coming years as we continue to advance our pipeline."

Dr. Yong-Jiang Hei, Chief Medical Officer for Oncology of Zai Lab said, "We believe ZEJULA is a best-in-class PARP inhibitor due to its compelling efficacy, once-daily dosing and superior pharmacokinetic properties including its ability to cross the blood brain barrier. The NDA submission based on the Category 1 designation of ZEJULA is a result of China-based clinical trials and manufacturing conducted by Zai Lab. We plan to expand our development efforts in collaboration with our partner Tesaro across several additional indications including, but not limited to, first-line maintenance treatment of ovarian cancer, lung cancer and gastric cancer."

William Liang, Chief Commercial Officer noted, "The Zai Lab commercial team is very excited about the attractive profile of ZEJULA and plans to leverage ZEJULA’s recent Hong Kong approval and commercial launch to prepare for the launch in China. If approved, we believe ZEJULA will provide a differentiated treatment option to benefit more ovarian cancer patients. We also intend to closely collaborate with local authorities and NGOs to develop patient assistant programs to increase access to more women who could benefit from this treatment. Zai Lab is committed to making a meaningful impact on the way cancer is treated in China and will continue to develop and bring new innovative oncology treatment options to patients in need."

About Ovarian Cancer

Ovarian cancer is one of the most common gynecologic cancers in China with approximately 51,000 newly diagnosed cases and 23,000 deaths in China in 2014. The 5-year overall survival rate of ovarian cancer patients is 46% across all stages, but only 29% in patients are diagnosed with distant metastatic disease. While platinum-based chemotherapy is effective at inducing an initial response in ovarian cancer, the disease will recur in the majority of women. Effective treatment options for patients with platinum-sensitive recurrent ovarian cancer remain limited. New agents that prolong the duration of response following platinum-based treatment and delay the inevitable relapse of ovarian cancer will benefit patients with ovarian cancer in China.

About ZEJULA

ZEJULA (niraparib, ZL-2306) is a highly potent and selective oral, once-daily small molecule poly (ADP-ribose) PARP 1/2inhibitor. It was approved in March 2017 by the FDA in the United States and in November 2017 by the EMA in the European Union under the trade name ZEJULA as a maintenance treatment for women with recurrent epithelial ovarian, fallopian tube, or primary peritoneal cancer who are in a complete or partial response to platinum-based chemotherapy. Based on the approval status in the United States and European Union by our partner, Tesaro, Zai Lab has obtained the approval for marketing ZEJULA in Hong Kong in October 2018.

On December 12, 2018 OncoSec Medical Incorporated (OncoSec) (NASDAQ:ONCS), a company developing novel cancer immunotherapies, reported an update regarding tumor responses in its KEYNOTE-695 global, multicenter Phase 2b, open-label trial of intratumoral delivery of TAVO (tavokinogene telseplasmid / IL-12) with intravenous KEYTRUDA (pembrolizumab) in patients with unresectable, advanced melanoma (Press release, OncoSec Medical, DEC 12, 2018, View Source [SID1234532030]). The Company previously reported at the Society for Immunotherapy of Cancer (SITC) (Free SITC Whitepaper)’s 33rd Annual Meeting (SITC) (Free SITC Whitepaper) that, of the first nine patients to complete 12 weeks of treatment and reach initial tumor evaluation (by RECIST v1.1), two patients had a partial response. The Company now reports that both responses have been confirmed by blinded independent review at the first assessment timepoint. Further, in both cases, response duration has now reached six months. Importantly, one of these previously assessed partial responses has now become a complete response per investigator assessment at the six-month tumor evaluation timepoint. Enrollment is ongoing and the Company expects to complete the study next year.

"Complete responses in this patient population are rare. One of the first partial responses to be observed in this study now being assessed by the investigator at six months as a complete response is exciting. Durable responses reaching the six-month mark demonstrate that the benefits of TAVO are clinically meaningful," said Daniel J. O’Connor, President and CEO of OncoSec. "The evidence of the potential of TAVO in conjunction with PD-1 inhibition to improve outcomes in this patient population is mounting and we look forward to providing updates as necessary regarding the progress of this trial."

KEYNOTE-695 enrollment criteria with respect to anti-PD-1 checkpoint failure is highly restrictive. In order to be considered an anti-PD-1 checkpoint failure, all patients must have Stage III/IV metastatic melanoma progressive disease after at least four prior cycles of either KEYTRUDA or OPDIVO. Literature suggests that retreatment with a PD-1 therapy following failure of a PD-1 therapy offers approximately a 5% response rate1. Disease progression is determined according to RECIST v1.1, measured by radiologic assessment, with confirmation of progression by second assessment.

"It’s becoming clear that TAVO can reverse PD-1 resistance in refractory metastatic melanoma patients. This is important because the majority of melanoma patients do not respond to PD-1 treatment," said Adil Daud, MD, HS Clinical Professor, Department of Medicine (Hematology/Oncology), UCSF; Director, Melanoma Clinical Research, UCSF Helen Diller Family Comprehensive Cancer Center and Lead Principle Investigator of KEYNOTE-695. "Patients in KEYNOTE-695 have unequivocally failed all approved anti-PD-1 therapies. The tumor responses seen in this trial, now independently verified by a blinded review at the first assessment, deepening and continuing for months, gives us confidence in the potential of this treatment combination for patients who are non-responsive to anti-PD-1 therapy."

Eligible patients in KEYNOTE-695 had refractory, locally advanced or metastatic disease defined as unresectable Stage III/IV metastatic melanoma that had definitively progressed on a full-course of anti-PD-1 treatment with KEYTRUDA (pembrolizumab) or OPDIVO (nivolumab). As previously reported, TAVO was well-tolerated, with primarily Grade 1 adverse advents associated with injection site or procedural pain. One TAVO related Grade 3 SAE of cellulitis was reported and resolved. KEYNOTE-695 is expected to be completed in 2019. Based on the outcome of the study, the Company plans to file for accelerated approval by end of 2019 or early 2020.

TAVO has received both Orphan Drug and Fast-Track Designation by the U.S. Food & Drug Administration.

On December 12, 2018 NETRIS Pharma, a clinical-stage company developing novel anticancer therapies targeting dependence receptors, reported successful completion of the first-in-human study on the effects of netrin-1 inhibition in patients with advanced solid tumors (Press release, Netris Pharma, DEC 12, 2018, View Source [SID1234611180]). The Phase 1 dose-escalation study showed that NP137, a first-in-class monoclonal anti-netrin-1 blocking antibody, was safe and well tolerated up to 20mg/kg, with no dose limiting toxicity (DLT), meeting the primary objective. In addition, patients with advanced uterine cancers exhibited encouraging signs of anti-tumor activity, including prolonged stable disease and objective response.

"We are very pleased with the safety and tolerability profile of NP137 in this study, which enabled evaluation of netrin-1 inhibition in advanced solid tumors," said Philippe Cassier, MD, PhD, Head of Phase 1 unit at Centre Léon Bérard and Principal Investigator of the NP137 study.

"I am really impressed by the preliminary anti-tumor activity observed in this study with patients showing objective response and prolonged one-year disease control," added Professor Jean Yves Blay, MD, Ph.D. General Director of the Centre Léon Bérard and past president of EORTC.

The Phase 1 study was designed to evaluate the maximum tolerated dose, pharmacokinetics and pharmacodynamics, and establish the recommended dose for the Phase 1b/2 expansion study. NP137 was dosed every other week starting from 1 mg/kg up to 20mg/kg in heavily pre-treated patients with advanced solid tumors. Additional study objectives were to evaluate the adverse events (AE), pharmacokinetics (PK), pharmacodynamics (PD) and preliminary anti-tumor activity of NP137. The study enrolled a total of 19 patients in three French centers, the Centre Léon Bérard in Lyon, the Institut Claudius Régaud in Toulouse and the Institut de Cancérologie de l’Ouest in Nantes. A Phase 1 extension study with an additional 24 patients is ongoing to confirm the safety and tolerability of NP137, collect biopsies before and after treatment to allow measurement of potential biomarkers and confirm the preliminary clinical activity seen during dose escalation. The final phase 1a data will be submitted for presentation at an upcoming international medical conference.

"Meeting the primary objective of the dose-escalation part of this study and generating preliminary positive efficacy data, particularly in such chemotherapy-resistant patients, provide an important confirmation of our dependence receptor science and lay the groundwork for larger clinical studies with NP137 as a targeted approach to treat solid tumors in combination with chemotherapy, immune checkpoint inhibitors and tyrosine kinase inhibitors," said Prof. Patrick Mehlen, Chief Executive Officer of NETRIS Pharma. "Additionally, we would like to thank the investigators, patients and caregivers for their participation in this study, and for contributing to our understanding of NP137 as we work to address a significant medical need."

About NP137
Most types of tumors produce an abnormal amount of dependence receptors’ ligands, which prevents cells from dying. Netrin-1 is overexpressed in a large percentage of human cancers, including over two thirds of gynecologic cancers. Expression of netrin-1 often correlates with disease severity and no therapy has ever been tested against this new pathway.

NP137, a humanized monoclonal antibody of isotype IgG1 directed against netrin-1, is the first drug candidate developed by NETRIS Pharma. NP137 prevents the binding of netrin-1 on its dependence receptors, thereby re-inducing cancer cell death and impacting tumor cell plasticity. Pre-clinical studies show NP137 to have an anti-cancer effect as a monotherapy as well as synergistic effects in combination with chemotherapy, immune checkpoint inhibitors or tyrosine kinase inhibitors.
