Under the terms of the agreement, Evotec OAI will use their leading-edge integrated drug discovery platform to select and synthesise lead compounds with optimised properties for Rigel to screen against their target proteins, and to identify novel scaffolds from Evotec OAI’s portfolio of validated chemistries, with the aim of identifying an IND candidate in 12 months. Initially, Evotec OAI’s molecular modelling expertise and computational platform will be used to perform SAR (structure activity relationship) analysis including pharmacophore modelling and in silico docking studies on selected Rigel small molecule drug leads. These proprietary compounds have been identified as most active in Rigel’s anti-cancer programme on ubiquitin ligases. This information will be used to select and synthesise the additional lead compounds.

Additionally, Evotec OAI will use their computational chemistry expertise to analyse Rigel’s corporate library and to identify additional scaffolds to increase the overall diversity of the library whilst retaining the drug and lead-like properties. Through the agreement, Rigel will also gain access to Evotec OAI’s lead discovery library for screening against the ligase and additional Rigel targets.

Rigel will provide funding to Evotec OAI for services conducted during this programme. In addition, Evotec OAI may receive future milestone payments if discovery projects meet defined goals and products are commercialised.

"We look forward to building a partnership with Rigel in their very exciting area of ubiquitin ligase research," said Mario Polywka, Chief Operating Officer of Evotec OAI. "Using our world class drug discovery platform will enable us to assist Rigel in accelerating their drug discovery programme."

"Rigel has built a very strong capability in ubiquitin ligase research and drug development, including the design of numerous biochemical and cellular assays to analyze the biology and proteomics of ligases, a robust and efficient high throughput screening program, a focused chemistry program with promising initial chemical hits and an experienced preclinical oncology development team," said James M. Gower, Rigel’s President and Chief Executive Officer. "This collaboration marks our second this month in the area of ubiquitin ligases, and Evotec’s expertise in computational and medicinal chemistry will contribute greatly to our ability to rapidly identify a clinical candidate in this promising new area of research."

On March 22, 2018 Evotec AG (Frankfurt Stock Exchange: EVT, TecDAX 30) reported that DAC (a wholly owned subsidiary of Genextra SPA) has chosen Evotec as a strategic partner to identify small molecule therapeutics in a pharmaceutical discovery project on the HSP90 target, a key protein involved in a variety of oncogenic pathways in several cancer related diseases (Press release, Evotec, MAR 22, 2018, View Source;announcements/press-releases/p/dac-selects-evotec-as-strategic-partner-for-a-drug-discovery-collaboration-on-the-hsp90-cancer-target-4520 [SID1234525395]).

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 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 APEIRON Biologics AG
Apeiron is a mostly privately financed biotech company in Vienna that develops immunological/biological therapies against cancer. Its portfolio consists of five clinical projects (lead in phase III) as well as some preclinical approaches. The most advanced project APN311 is an antibody to treat the pediatric cancer neuroblastoma. The immunocytokine hu14.18-IL2 (APN301) is being developed clinically in neuroblastoma as well as in melanoma. Moreover, recombinant human superoxide dismutase is in clinical development, notably in a topical liposomal formulation (APN201) as a potent anti-inflammatory tissue-protective biologic. Two complementary approaches are pursued (APN401, APN411) that stimulate immune cells in a novel way to treat cancer more effectively. The recombinant human Angiotensin Converting Enzyme 2 (GSK2586881, previously APN01) was licensed out to GlaxoSmithKline in early 2010 and is currently investigated in a phase II trial in patients suffering from acute lung injury. Apeiron started operations in 2006 and has 23 employees as of today.
