On June 27, 2017 Affimed N.V. (Nasdaq: AFMD), a clinical stage biopharmaceutical company focused on discovering and developing highly targeted cancer immunotherapies, reported the presentation of preclinical data for the Company’s AFM24 and AFM26 programs at the EACR-AACR-SIC 2017 Special Conference in Florence, Italy (Press release, Affimed, JUN 27, 2017, View Source [SID1234519711]).

"With our NK-cell engagers AFM24 and AFM26 we are pursuing two preclinical programs which we believe are ideally suited to exploit NK-cell mediated cytotoxicity to fight cancer," said Dr. Martin Treder, Chief Scientific Officer of Affimed. "Our data for both programs show a well-differentiated profile from competitor products, addressing the need for higher efficacy and better safety."

AFM24 and AFM26 are two first-in-class tetravalent, bispecific NK-cell engagers targeting CD16A, a dominant activating receptor on NK-cells. In addition, AFM24 targets EGFR, while AFM26 binds to BCMA. Corroborating the Company’s earlier data, the studies presented at EACR-AACR-SIC 2017 provided further evidence of favorable safety profiles for both NK-cell engagers and also confirmed their ability to potently and effectively lyse tumor cells, even those with very low target expression. Furthermore, the high affinity to CD16A on NK-cells, resulting in long cell retention binding to NK-cells, and the minimal influence of serum IgG on tumor cell lysis are important differentiating factors of Affimed’s NK-cell platform compared to IgG-based monoclonal antibodies (mAbs).

In detail, AFM24 was shown to be distinguished from cetuximab in vitro and in vivo through higher potency at both high and low EGFR expression levels and in RAS mutant cells, while offering a more favorable safety profile. Single and repeat dose toxicology studies in cynomolgus monkeys demonstrated that AFM24 was well-tolerated at high doses. Further differentiating AFM24 from other therapies, no evidence of skin toxicity, a side effect commonly seen for other anti-EGFR antibodies and for tyrosine kinase inhibitors, was observed.

In addition, the Company presented further data highlighting the preclinical progress of AFM26. The NK-cell engager was able to elicit efficient tumor cell lysis in both cell lines and primary cells, even at very low BCMA expression levels. In addition, the amount of inflammatory cytokines released in vitro by cells treated with AFM26 was markedly lower than those of cells treated with a BCMA/CD3 T-cell engager. Furthermore, in contrast to approved mAb therapies such as daratumumab and elotuzumab, AFM26 did not induce NK-cell depletion in vitro.

Taken together, the results presented at EACR-AACR-SIC 2017 support the therapeutic rationale of redirecting NK-cells to tumors through bispecific tetravalent NK-cell engagers, which offers a novel mode of action addressing limitations of other therapies.

On June 27, 2017 Ablynx [Euronext Brussels: ABLX; OTC: ABYLY] reported that Merck & Co., Inc., Kenilworth, New Jersey, USA, known as MSD outside the United States and Canada, has started an IND-enabling toxicology study with a bi-specific Nanobody as part of the immuno-oncology collaboration between the companies (Press release, Ablynx, JUN 27, 2017, View Source [SID1234519710]). This milestone triggers a €2.5 million payment to Ablynx.

This Nanobody is a bi-specific molecule that selectively binds to two different immune modulators, believed to be key targets for the development of potent immunotherapies. Upon successful completion of the IND package, this bi-specific Nanobody could be the first candidate to enter clinical studies as part of this collaboration.

Dr Edwin Moses, CEO of Ablynx, commented: "We are very pleased with the progress made in this collaboration. We believe that the combination of Ablynx’s Nanobody expertise with the world-leading position of our partner in the immuno-oncology area has the potential to develop important new medicines for diseases with a high unmet need. We look forward to further milestones as product candidates progress through pre-clinical and clinical development."

About the immuno-oncology collaboration between Ablynx and Merck & Co., Inc., Kenilworth, New Jersey, USA In February 2014, Ablynx entered into a research collaboration and licensing agreement with a subsidiary of Merck & Co., Inc., Kenilworth, New Jersey, USA. This exclusive collaboration and licensing agreement is focused on the discovery and development of several Nanobody candidates (including mono-, bi-and trispecifics) directed toward so-called immune checkpoint modulators. In July 2015, Ablynx announced an expansion of this immuno-oncology collaboration with Merck & Co., Inc., Kenilworth, New Jersey, USA to address an increased number of immune checkpoint modulator targets. The collaboration now includes up to 17 Nanobody programmes against individual protein targets and target combinations (monospecific and multi-specific Nanobodies). Ablynx has received €33 million in upfront payments and is eligible to receive research funding plus development, regulatory and commercial milestone payments of up to €340 million per programme, as well as tiered royalties on annual net sales upon commercialisation of any Nanobody products.

Merck & Co., Inc., Kenilworth, New Jersey, USA, through a subsidiary, and Ablynx have a separate collaboration in the field of ion channel drug development, announced in October 2012, with a €6.5 million upfront payment, €2 million research funding and up to €448 million in research, regulatory and commercial milestone payments associated with the progress of multiple candidates as well as tiered royalties on any products derived from the collaboration. An initial extension of this ion channel research collaboration was announced in March 2015 and a second extension in October 2016, the latter triggering a €1 million payment to Ablynx and additional research funding to September 2018.

On June 27, 2017 Merck (NYSE:MRK), known as MSD outside of the United States and Canada, reported that the REVEAL (Randomized EValuation of the Effects of Anacetrapib through Lipid modification) outcomes study of anacetrapib met its primary endpoint, significantly reducing major coronary events (defined as the composite of coronary death, myocardial infarction, and coronary revascularization) compared to placebo in patients at risk for cardiac events who are already receiving an effective LDL-C lowering regimen. The safety profile of anacetrapib in the early analysis was generally consistent with that demonstrated in previous studies of the drug, including accumulation of anacetrapib in adipose tissue, as has been previously reported. Merck plans to review the results of the trial with external experts, and will consider whether to file new drug applications with the U.S. Food and Drug Administration (FDA) and other regulatory agencies. The results of the REVEAL study will be presented at the European Society of Cardiology meeting on Aug. 29, 2017.

Anacetrapib is Merck’s investigational cholesteryl ester transfer protein (CETP) inhibitor. The REVEAL study is a randomized, double-blind placebo-controlled clinical trial to assess the efficacy and safety of adding anacetrapib to effective LDL-lowering treatment with atorvastatin for a median duration of at least 4 years among approximately 30,000 patients at high risk of cardiovascular events. REVEAL was designed and independently conducted by investigators at the Clinical Trial Service Unit (CTSU) at the University of Oxford, the trial’s regulatory sponsor, in collaboration with the TIMI Study Group based at Brigham and Women’s Hospital in Boston and Merck. Merck provided funding for REVEAL. Details on the REVEAL study design are available at clinicaltrials.gov: View Source
