Under the agreement, DAC will access compound intellectual property that Evotec has generated on this disease target through its internal R&D activities. The aim of the collaboration will be to take compounds identified by Evotec as being active against the target and further optimise them to the point of clinical development.

Using its proprietary fragment screening platform (High Throughput Fragment Screening, HTFS), Evotec identified novel fragments that interact with the HSP90 target from Evotec’s five thousand member fragment library. Active fragments were further characterised by co-crystallisation with the target protein. The X-ray crystal structures of the protein-ligand complexes identified a variety of binding modes some of which will give rise to novel approaches for inhibiting HSP90. Following due diligence DAC has decided to collaborate with Evotec with the aim of improving the potency and selectivity of the identified compounds. In the collaboration, which may run for an initial period of over 2 years, Evotec will use its medicinal chemistry, profiling and ADMET (Absorption, Distribution, Metabolism, Excretion and Toxicity) expertise to generate lead molecules for further progression into clinical trials.

For its contributions to the discovery project Evotec will potentially receive single digit millions R&D service revenues and will also be eligible for additional preclinical and clinical milestone payments.

"We are delighted that DAC and Genextra, one of the most innovative and active biopharmaceutical companies in Italy, appreciated the value of the HSP90 inhibitors that we had identified using our novel approach to fragment screening and have selected us for this project. We are very excited about the potential for analogues of these compounds to be novel treatments for diseases that require inhibition of the HSP90 protein," said Dr Mark Ashton, Executive Vice President Business Development Services at Evotec. "This project represents another major milestone in our strategy to strengthen our collaborative relationships by providing our partners access to selected promising proprietary drug discovery assets discovered using our state-of-the-art platform."

"This project is an important extension of our lead discovery activities. From existing collaborations with Evotec, we remained positively impressed by Evotec’s medicinal chemistry capabilities and this, together with the results that Evotec had already generated against this disease target, convinced us to collaborate on this exciting project," commented Mr Paolo Fundarò, Chief Executive Officer of Genextra.

On March 22, 2018 Array BioPharma Inc. (Nasdaq: ARRY) reported that detailed results of its pivotal Phase 3 COLUMBUS trial for the treatment of patients with BRAF-mutant advanced, unresectable or metastatic melanoma were published in The Lancet Oncology (Press release, Array BioPharma, MAR 22, 2018, View Source;p=RssLanding&cat=news&id=2339334 [SID1234524945]). In the analysis of the primary endpoint, the median progression-free survival (mPFS) for patients treated with the combination of encorafenib, 450 mg daily, plus binimetinib, 45 mg twice daily (COMBO450) was 14.9 months versus 7.3 months for patients treated with vemurafenib, 960 mg twice daily [hazard ratio (HR) 0.54, 95% CI 0.41–0.71; p<0.0001].

The manuscript entitled "Encorafenib plus binimetinib versus vemurafenib or encorafenib in patients with BRAF-mutant melanoma (COLUMBUS): a multicentre, open-label, randomised phase 3 trial," was published online on March 21, 2018. Array previously announced top line results from this study in September 2016.

"A median progression-free survival of nearly 15 months with the combination of encorafenib and binimetinib is clinically meaningful for patients with advanced BRAF-mutant metastatic melanoma," said Keith T. Flaherty, M.D., Director of the Termeer Center for Targeted Therapy, Massachusetts General Hospital Cancer Center and Professor of Medicine, Harvard Medical School. "Further, a median overall survival of 33.6 months, compared to 16.9 months with vemurafenib monotherapy (HR of 0.61, 95% CI 0.47-0.79, p<0.001), a secondary endpoint not included in this publication, was recently announced. This further supplements the published data and shows that the combination of encorafenib and binimetinib may become a promising new therapy for patients with advanced BRAF-mutant metastatic melanoma."

As previously reported, the combination of encorafenib and binimetinib was generally well-tolerated. The median duration of treatment was 51.2 weeks (27.1-79.7) for encorafenib and 50.6 weeks (26.1-79.7) for binimetinib. The median dose intensity was 100% (93-100) of planned doses of encorafenib and 99.6% (80-100) of planned doses of binimetinib. The most common Grade 3/4 adverse events (AEs) seen in more than 5% of patients were increased gamma-glutamyltransferase (GGT) 9% (18/192 patients), increased creatine phosphokinase 7% (13), and hypertension 6% (11) in the encorafenib plus binimetinib group.

The U.S. Food and Drug Administration (FDA) is currently reviewing the New Drug Applications to support use of the combination of encorafenib and binimetinib for the treatment of patients with BRAF-mutant advanced, unresectable or metastatic melanoma. The FDA set a target action date under the Prescription Drug User Fee Act (PDUFA) of June 30, 2018 for both applications. In addition, the European Medicines Agency (EMA), as well as the Swiss Medicines Agency (Swissmedic) and the Australian Therapeutic Goods Administration (TGA), are reviewing the Marketing Authorization Applications for encorafenib and binimetinib.

An update from the COLUMBUS trial will be presented at an upcoming medical congress.

About Melanoma
Metastatic melanoma is the most serious and life-threatening type of skin cancer and is associated with low survival rates. [1, 2] There are about 200,000 new cases of melanoma diagnosed worldwide each year, approximately half of which have BRAF mutations, a key target in the treatment of metastatic melanoma. [1, 3, 4]

About COLUMBUS
The COLUMBUS trial, (NCT01909453), is a two-part, international, randomized, open label Phase 3 trial evaluating the efficacy and safety of the combination of encorafenib and binimetinib compared to vemurafenib and encorafenib monotherapy in 921 patients with locally advanced, unresectable or metastatic melanoma with BRAFV600 mutation. Prior immunotherapy treatment was allowed. Over 200 sites across North America, Europe, South America, Africa, Asia and Australia participated in the trial. Patients were randomized into two parts:

In Part 1, 577 patients were randomized 1:1:1 to receive COMBO450, encorafenib, 300 mg daily (ENCO 300), or vemurafenib, 960 mg twice daily alone. The dose of encorafenib in the combination arm is 50% higher than the single agent maximum tolerated dose of 300 mg. A higher dose of encorafenib was possible due to improved tolerability when combined with binimetinib. The primary endpoint for the COLUMBUS trial was an mPFS comparison of the COMBO450 arm versus vemurafenib. mPFS is determined based on tumor assessment (RECIST version 1.1 criteria) by a Blinded Independent Central Review (BICR). Secondary endpoints include a comparison of the mPFS of COMBO450 arm to that of ENCO300 and a comparison of overall survival (OS) in patients treated in the COMBO450 arm to that of vemurafenib alone. Results from Part 1 of the COLUMBUS trial previously presented at the 2016 Society for Melanoma Research Annual Congress, showed that COMBO450 more than doubled mPFS in patients with advanced BRAF-mutant melanoma, with a mPFS of 14.9 months compared with 7.3 months observed with vemurafenib [HR 0.54, (95% CI 0.41-0.71, p<0.0001)]. In the secondary mPFS comparison of COMBO450 to ENCO300, ENCO300 demonstrated a mPFS of 9.6 months [HR 0.75, (95% CI 0.56-1.00, p=0.051)].
In Part 2, 344 patients were randomized 3:1 to receive encorafenib 300 mg plus binimetinib 45 mg twice daily (COMBO300) or ENCO300. Part 2 was designed to provide additional data to help evaluate the contribution of binimetinib to the combination of encorafenib and binimetinib.
As the secondary endpoint comparison of mPFS between the COMBO450 arm and ENCO300 arm in Part 1 did not achieve statistical significance, the protocol specified analysis of OS is descriptive.

About Encorafenib and Binimetinib
BRAF and MEK are key protein kinases in the MAPK signaling pathway (RAS-RAF-MEK-ERK). Research has shown this pathway regulates several key cellular activities including proliferation, differentiation, survival and angiogenesis. Inappropriate activation of proteins in this pathway has been shown to occur in many cancers including melanoma and colorectal cancer. Encorafenib is a late-stage small molecule BRAF inhibitor and binimetinib is a late-stage small molecule MEK inhibitor, both of which target key enzymes in this pathway. Encorafenib and binimetinib are being studied in clinical trials in advanced cancer patients, including the Phase 3 BEACON CRC trial and the Phase 3 COLUMBUS trial.

Array BioPharma has exclusive rights to encorafenib and binimetinib in the U.S. and Canada. Array has granted Ono Pharmaceutical exclusive rights to commercialize both products in Japan and South Korea and Pierre Fabre exclusive rights to commercialize both products in all other countries, including Europe, Asia and Latin America. Encorafenib and binimetinib are investigational medicines and are not currently approved in any country.

On March 22, 2018 Astellas Pharma Inc. (President and CEO: Yoshihiko Hatanaka, "Astellas" ) reported that the Japanese Ministry of Health, Labour and Welfare (MHLW) has granted Orphan Drug Designation to gilteritinib for the treatment of FLT3mut+ Acute Myeloid Leukemia (AML), the drug’s prospective indication (Press release, Astellas, MAR 22, 2018, View Source [SID1234536693]).

Orphan drug designation system in Japan aims to support the development of drugs for diseases that, despite there being a significant medical need for treatments, affect only a small number of patients, and for which research and development is virtually nonexistent. As stipulated in Article 77 of the Pharmaceuticals, Medical Devices, and Other Therapeutic Products Act of Japan, the designation is granted by the minister of Health, Labour and Welfare for drugs that meet the designation criteria which include the following: the number of patients who may use the drug is less than 50,000 in Japan; there is no alternative appropriate drug or treatment in Japan; high efficacy or safety is expected compared to existing products. Specific measures to support the development of orphan drugs include subsidies for research and development expenditures, prioritized consultation regarding clinical development, reduced consultation fees, tax incentives, priority review of applications, reduced application fees, and extended registration validity period1

AML is a cancer that impacts the blood and bone marrow, and its incidence increases with age. In Japan, approximately 5,500 patients are diagnosed with AML each year2. Gilteritinib is an investigational compound that has demonstrated inhibitory activity against FLT3 internal tandem duplication (ITD) as well as FLT3 tyrosine kinase domain (TKD), two common types of FLT3 mutations that are seen in approximately one-third of patients with AML. Further, gilteritinib has also demonstrated inhibition of the AXL receptor in AML cell lines.

Astellas will continue to develop gilteritinib to provide it to FLT3mut+ AML patients as early as possible.

About the Phase 2 TRINITY Study
TRINITY is a multicenter, open-label, single-arm, Phase 2 study of Rova-T in DLL3-expressing small cell lung cancer (SCLC) patients with relapsed/refractory (R/R) disease after receiving at least two previous regimens, including at least one platinum-based regimen. The primary objective was to investigate the efficacy of Rova-T as third-line and later treatment for R/R DLL3-expressing SCLC. Secondary objectives included assessment of safety and tolerability, pharmacokinetics, RECIST-assessed progression-free survival, duration of response and clinical benefit rate.

About Rovalpituzumab Tesirine (Rova-T)
Rova-T is an investigational antibody-drug conjugate targeting the cancer-stem cell-associated delta-like protein 3 (DLL3)[1], which is expressed in more than 80 percent of small cell lung cancer (SCLC) patient tumors, where it is prevalent on tumor cells, including cancer stem cells, but not present in healthy tissue.[2] Rova-T combines a targeted antibody that delivers a cytotoxic agent directly to the DLL3-expressing cancer cells while minimizing toxicity to healthy cells. Rova-T is under investigation as a third-line treatment in SCLC.[2] The expression of DLL3 suggests Rova-T may be useful across multiple tumor types, including metastatic melanoma, glioblastoma multiforme and some prostate, pancreatic and colorectal cancers.[2]
Rova-T is an investigational compound and its efficacy and safety have not been established by the FDA or any other health authority.
