HMP Announces First Commercial Launch of Fruquintinib Capsules (Elunate®)

Shanghai: Monday, November 26, 2018: Hutchison MediPharma (“HMP”) today announces the first commercial launch of fruquintinib capsules (Elunate®) with the initiation of product sales in China. Elunate® is for the treatment of patients with metastatic colorectal cancer (“CRC”) that have been previously treated with fluoropyrimidine, oxaliplatin and irinotecan, including those who have previously received or are unsuitable for anti-vascular endothelial growth factor (VEGF) therapy and/or anti-epidermal growth factor receptor (EGFR) therapy (Ras wild type).

CRC is the second most common cancer type in China[i], with about 380,000 new cases per year[ii]. The market launch of Elunate® in China is being conducted through collaboration with Chi-Med’s partner Eli Lilly and Company (“Lilly”).

Fruquintinib was first approved by the National Medical Products Administration of China (“NMPA”) in September 2018 for the treatment of advanced CRC, becoming the first China-discovered and -developed pharmaceutical for a mainstream oncology indication to be unconditionally approved in China. Chi-Med has established a manufacturing facility in Suzhou, China to produce fruquintinib.

Dr. Wang Li, Senior Vice President, Head of Lilly China Drug Development & Medical Affairs Center, said, “We look forward to working with Chi-Med to bring this novel medicine to patients, addressing the significant unmet need in colorectal cancer in China.”

Given the broad relevance of anti-angiogenesis therapies in cancer biology and the observed effects in various cancers to date, Chi-Med is developing fruquintinib in multiple further indications, including in combination with other cancer therapies.

About Other Fruquintinib Development Programs

Global Development

Phase I monotherapy in the U.S.: In December 2017, Chi-Med initiated a multi-center, open-label, Phase I clinical study to evaluate the safety, tolerability and pharmacokinetics of fruquintinib in U.S. patients with advanced solid tumors (clinicaltrials.gov identifier NCT03251378). This study is almost complete, and proof-of-concept (“POC”) studies are expected to begin in 2019.

China Development

Colorectal cancer in China: The NMPA approved the first NDA for fruquintinib for the treatment of patients with advanced CRC in September 2018. The NDA is supported by data from the successful FRESCO study, a Phase III pivotal registration trial of fruquintinib in 416 patients with CRC in China, which was highlighted in an oral presentation at the American Society of Clinical Oncology Annual Meeting held on June 5, 2017 and was published in The Journal of the American Medical Association, JAMA, in June 2018 (clinicaltrials.gov identifier NCT02314819).

Gastric cancer in China: In October 2017, Chi-Med initiated a pivotal Phase III clinical trial of fruquintinib in combination with Taxol® (paclitaxel), known as the FRUTIGA study, in approximately 500 patients with advanced gastric or gastroesophageal junction (GEJ) adenocarcinoma who have progressed after first-line standard chemotherapy (clinicaltrials.gov identifier NCT03223376). An interim analysis on FRUTIGA, to establish POC, is anticipated during the first half of 2019 and if successful could trigger a POC milestone payment from Lilly. The FRUTIGA study followed a Phase I/II clinical trial in 34 patients with gastric cancer that demonstrated that combination therapy of fruquintinib and Taxol® was generally well-tolerated with promising tumor response (clinicaltrials.gov identifier NCT02415023).

Lung cancer in China: The FALUCA trial is a randomized, double-blind, placebo-controlled, multi-center, Phase III registration study targeted at treating patients with advanced non-squamous non-small cell lung cancer (“NSCLC”), who have failed two lines of systemic chemotherapy. 527 patients were randomized at a 2:1 ratio to receive either: 5mg of fruquintinib orally once per day, on a three-weeks-on / one-week-off cycle, plus best supportive care (“BSC”); or placebo plus BSC. On November 16, 2018, Chi-Med announced that FALUCA did not meet the primary endpoint to demonstrate a statistically significant increase in overall survival compared to placebo, however the data did show statistically significant improvement in all secondary endpoints including progression-free survival, objective response rate, disease control rate and duration of response as compared to the placebo. The safety profile of the trial was in line with that observed in prior clinical studies. Full detailed results are expected to be disclosed at an upcoming scientific meeting. Additional details about this study can be found at clinicaltrials.gov, using identifier NCT02691299.

Along with FALUCA, fruquintinib is concurrently being studied in a Phase II study in combination with Iressa® (gefitinib) in patients with untreated advanced or metastatic NSCLC (clinicaltrials.gov identifier NCT02976116). Preliminary results were highlighted in an oral presentation at the 18th World Conference on Lung Cancer on October 16, 2017.

Programmed cell death protein-1 (“PD-1”) checkpoint inhibitor combination: It is an important part of Chi-Med’s strategy to explore the potential synergies of its drug candidates in combination with other anti-cancer treatments in several solid tumor settings. In October 2018, Chi-Med entered into a further collaboration in China to evaluate the combination of fruquintinib with genolimzumab (GB226), a PD-1 inhibitor being developed by Genor Biopharma Company Limited.

About Fruquintinib

Fruquintinib (brand name: Elunate®) is a small molecule, selective and highly potent inhibitor of VEGFR 1, 2 and 3. VEGFR inhibitors play a pivotal role in tumor-related angiogenesis, cutting off the blood supply that a tumor needs to grow rapidly. The global market for anti-angiogenesis therapies was estimated at over US$18 billion in 2017, including both monoclonal antibodies and small molecules approved in around 30 tumor settings. During the discovery research process, which began at Chi-Med in 2007, fruquintinib was successfully designed to be differentiated by improving kinase selectivity in comparison to other approved small molecule tyrosine kinase inhibitors (TKIs), to minimize off-target toxicities, improve tolerability and provide more consistent target coverage, resulting in better clinical efficacy. The superior tolerability, along with fruquintinib’s low potential for drug-drug interaction based on preclinical assessment, suggests that it may be highly suitable for innovative combinations with other anti-cancer therapies.

In October 2013, Chi-Med entered into a licensing, co-development and commercialization agreement in China with Lilly for fruquintinib. Under the terms of the agreement, the costs of development of fruquintinib, carried out by Chi-Med, are shared; Chi-Med has received upfront payments and development and regulatory approval milestone payments; and upon commercialization in China, Chi-Med would receive royalties. Chi-Med and Lilly agreed to develop fruquintinib in three initial solid tumor indications, including CRC, NSCLC and gastric cancer.

The most common adverse reactions included hypertension, hand-foot syndrome and proteinuria. Clinically effective management of these adverse effects is feasible. For important safety information about fruquintinib, please see www.chi-med.com.
