Z53 Therapeutics is based on intellectual property exclusively licensed from Rutgers University and SUNY Upstate Medical University in Syracuse, N.Y., which was developed by the laboratory of scientific founder Darren Carpizo, M.D., Ph.D., Surgical Oncologist at The Rutgers Cancer Institute of New Jersey. The work was done in collaboration with the synthetic chemistry laboratories of Rutgers Translational Sciences, headed by S. David Kimball, Ph.D., Associate Vice President Research Translation and Commercialization, and the biochemistry and molecular biology laboratory of Stewart Loh, Ph.D., at SUNY Upstate.

"I am very excited to collaborate with BioMotiv to advance our research from our initial discoveries and mechanistic work to the identification of compounds that can be used in the clinic to target a wide spectrum of tumors with specific p53 mutations", said Dr. Carpizo.

The p53 protein has been called the "the guardian of the human genome" for its central role in suppressing tumor formation. The gene encoding p53 is the most commonly mutated gene in human cancer with a large number of mutations resulting in a defect in the protein’s structure due to an impairment in the ability of the protein to bind zinc (so-called zinc deficient mutant p53). Dr. Carpizo and colleagues discovered that small molecules could restore the normal structure and function to zinc deficient mutant p53. Dr. Carpizo, along with Dr. Loh, went on to elucidate the mechanism of action of these compounds to be a restoration of zinc binding in mutant p53 which they have named "zinc metallochaperones".

Zinc metallochaperones represent a novel class of anti-cancer drugs. "The pharmacologic restoration of structure and function of a mutant protein by the delivery of a metal ion is unprecedented in drug development," said Dr. Carpizo. Together with Drs. Loh and Kimball, the research team has identified novel zinc metallochaperones which will be developed by Z53 Therapeutics. Dr. Carpizo goes on to say, "Targeting mutant p53 with small molecule compounds has been one of the holy grails of drug development, so it is very exciting to be a forefront of this field of research."

Christopher Molloy, Ph.D., Senior Vice President for Research and Economic Development at Rutgers, said, "The rapid progress in identifying a biologically active lead chemical series provides validation for Rutgers’ investment in pre-clinical translational research, which is being led by Dr. Kimball. We are pleased that this agreement provides additional resources to allow Dr. Carpizo and our translational sciences team to advance the research on these promising discoveries."

"The discoveries made by Dr. Carpizo have great promise," said Baiju R. Shah, Chief Executive Officer of BioMotiv. "We are looking forward to partnering with him in developing those discoveries in Z53 Therapeutics."

Dr. Carpizo is a Harrington Scholar-Innovator whose work has been supported by the Harrington Discovery Institute of University Hospitals in Cleveland. His laboratory is also funded by the National Cancer Institute, Sidney Kimmel Cancer Foundation, and the Breast Cancer Research Foundation.

Over the past 2 years, the techtransfer office SATT Conectus supported the team to develop the technology up to the proof of concept. PeptiMimesis was founded by three academic researchers, each having more than 15 years of experience in the field of transmembrane peptides, and Domain Therapeutics, a drug discovery company with a long and successful track record in targeting membrane receptors.

"This new venture highlights the quality of the incubation phase conducted by SATT Conectus and the high standard of research carried out by the University of Strasbourg and INSERM," said Pascal Neuville, CEO of Domain Therapeutics.

"The creation of PeptiMimesis is the culmination of many years of work developing our technology," said Dr Dominique Bagnard, founder. "With my two long – standing collaborators and co – founders, Dr Gérard Crémel and Dr Pierre Hubert, we are pleased to partner with Domain Therapeutics to develop our research, and launch PeptiMimesis on the road to success."

"Domain Therapeutics is ideally positioned to help bridge the gap between a breakthrough technology developed by a nascent company and the expectations of pharma partners. We strongly believe that our expertise will allow PeptiMimesis’ platform to deliver promising and valuable peptides to answer patient needs," said Pascal Neuville.

About therapeutic peptides
There are more than 60 US Food and Drug Administration (FDA) approved peptide medicines currently on the market. This is expected to grow significantly, with approximately 140 peptide drugs in clinical trials and more than 500 therapeutic peptides in preclinical development. In terms of value, the global peptide drug market is predicted to increase from $14.1Bn ( € 12.1Bn) in 2011 to an estimated $25.4Bn ( € 22.7Bn) in 2018, with an underlying increase in novel innovative peptide drugs from $8.6Bn ( € 7.7Bn) in 2011 (60%) to $17.0Bn ( € 15.2Bn) in 2018 (66%).

About transmembrane therapeutic peptides
Peptides possess key competitive advantages over antibodies such as a faster drug discovery process and a reduced manufacturing cost. In addition, the novel class of peptides developed by PeptiMimesis presents lower immunogenicity as they rapidly set within cellular membranes. The peptides also demonstrate an amplified therapeutic efficacy through indirect inhibition of multiple co – receptors and their associated signalling pathways. This innovative approach relies on the disruption of dimerization of membrane receptors using peptides that interfere with the transmembrane sites of oligomerization.

"I am thrilled with MacroGenics’ progress towards advancing breakthrough biologics and life-changing medicines, and particularly our industry leadership in creating bi-specific molecules," said Scott Koenig, M.D., Ph.D., President and CEO of MacroGenics. "There are now six Dual-Affinity Re-Targeting, or DART, molecules based on our proprietary platform, in or entering clinical development — four led by MacroGenics and two led by our collaborators, Janssen Biotech and Pfizer. In addition, we are actively enrolling patients with metastatic breast cancer in SOPHIA, our Phase 3 study of our Fc-optimized HER2 antibody, margetuximab. During 2015, in addition to updating our Phase 1 margetuximab data at the ASCO (Free ASCO Whitepaper) annual meeting, we also reported encouraging initial results from an ongoing Phase 1 study of enoblituzumab, our Fc-optimized B7-H3 antibody, at the SITC (Free SITC Whitepaper) annual meeting. Finally, given the strength of our cash and investments balance, we continue to be well positioned to advance our proprietary pipeline of immunotherapeutic product candidates."

"For 2016, we have already initiated a Phase 1b/2 study combining margetuximab and pembrolizumab in advanced HER2-positive gastric cancer," added Dr. Koenig. "Later this year, we plan to share additional enoblituzumab clinical data and provide clinical updates on multiple DART molecules being evaluated in Phase 1 studies. We also expect to submit an Investigational New Drug (IND) application for MGA012. Over the next few years, we intend to continue to advance at least one additional IND per year."

Pipeline Update

Margetuximab is an Fc-optimized monoclonal antibody that targets the human epidermal growth factor receptor 2, or HER2. Recent highlights include:

Phase 1b/2 Gastric Cancer Study: MacroGenics recently dosed the first patient in a Phase 1b/2 clinical trial of margetuximab in combination with pembrolizumab, an anti-PD-1 therapy, in patients with advanced HER2-positive gastric cancer. Treatment options for these patients are limited and our proposed combination regimen would avoid chemotherapy while exploiting the expected enhanced immune-mediated killing properties of both margetuximab and pembrolizumab. We recently elected to expand the scope of this trial to include centers in both Asia and the United States. This study is being conducted in collaboration with Merck.
SOPHIA Study: The Company’s Phase 3 pivotal study in patients with HER2-positive metastatic breast cancer is ongoing, as the Company continues to initiate sites and enroll patients. This study is evaluating the efficacy of margetuximab plus chemotherapy compared to trastuzumab plus chemotherapy in approximately 530 patients following progression after at least two lines of previous therapy. The Company is targeting completion of this study in 2018.

B7-H3 Franchise. MacroGenics is developing a portfolio of therapeutics that target B7-H3, a member of the B7 family of molecules involved in immune regulation. The Company is advancing multiple programs that target B7-H3 through complementary mechanisms of action and take advantage of this antigen’s broad expression across multiple solid tumor types. Recent highlights of ongoing clinical programs include:

Enoblituzumab (MGA271): Data from the ongoing monotherapy study of enoblituzumab, an Fc-optimized monoclonal antibody that targets B7-H3, was presented in a late-breaking abstract session at the 2015 Society for Immunotherapy of Cancer (SITC) (Free SITC Whitepaper) Annual Meeting in November. Enoblituzumab has been generally well tolerated in patients and has shown encouraging initial single-agent, anti-tumor activity in heavily pre-treated patients, including those with prostate and bladder cancer as well as melanoma. In addition, evidence of T-cell immunomodulatory function has been observed in patients treated with enoblituzumab. The Company has expanded its development program to include two combination studies with either ipilimumab or pembrolizumab.
MGD009: This DART molecule targeting B7-H3 and CD3 is being evaluated in a Phase 1 study across multiple solid tumor types.

DART Product Candidates. There are currently six DART molecules in or entering Phase 1 clinical development, including MGD006 (CD123 x CD3, also known as S80880), MGD007 (gpA33 x CD3), MGD011 (CD19 x CD3, also known as JNJ-64052781), MGD010 (CD32B x CD79B), MGD009 (B7-H3 x CD3) and PF-06671008 (P-cadherin x CD3). The Company expects to submit IND applications for two additional DART molecules in 2017. These two product candidates are:

MGD013: MacroGenics is developing an Fc-bearing DART molecule, MGD013, to simultaneously block two immune checkpoint molecules, PD-1 and LAG-3. The Company has presented promising pre-clinical data demonstrating the activity of a DART molecule with these specificities and expects that this bi-specific combination may be useful for treatment of a wide range of solid tumors and hematological malignancies.
MGD014: In 2015, MacroGenics presented pre-clinical data on MGD014, a DART molecule that is being developed to eliminate latent HIV infection. MGD014 is being developed under a contract awarded to MacroGenics by the National Institute of Allergy and Infectious Diseases for up to $24.5 million. This is the first infectious disease DART program planned for clinical testing.

Beyond MGD013 and MGD014, MacroGenics is generating and evaluating multiple other candidates that target a range of immune regulatory and other molecules using both its DART and Trident platforms, the latter for generating tri-specific molecules.

Corporate Update

Commercial Preparation: Tom Farrell recently joined MacroGenics as Vice President, Market Development and Strategy and will lead the Company’s effort in preparing for commercialization of its lead product candidates. Tom was most recently at Genentech, a Member of the Roche Group, where he was Global Pricing & Market Access Head (Oncology/Hemophilia), and responsible for leading the development and implementation of global pricing and payer strategies for all oncology (including Perjeta and Kadcyla) and hemophilia molecules from early- through late-stage development.
Pfizer’s DART Molecule Advances: MacroGenics’ collaboration partner, Pfizer, recently advanced PF-06671008, a DART molecule that targets P-cadherin and CD3, by submitting an IND application that has been cleared by the FDA. Increased levels of the protein P-cadherin have been reported in various tumors, including breast, gastric, endometrial, colorectal and pancreatic cancers, and is correlated with poor survival of patients.

2015 Financial Results and Financial Guidance

Cash Position: Cash, cash equivalents and investments as of December 31, 2015 were $339.0 million, compared to $157.6 million as of December 31, 2014.
