About APX005M
APX005M is a novel, humanized monoclonal antibody that stimulates the anti-tumor immune response. APX005M targets CD40, a co-stimulatory receptor that is essential for activating both innate and adaptive immune systems. Binding of APX005M to CD40 on antigen presenting cells (i.e., dendritic cells, monocytes and B-cells) initiates a multi-faceted immune response bringing multiple components of the immune system (e.g., T cells, macrophages) to work in concert against cancer. APX005M is currently in Phase 2 clinical development for the treatment of cancers such as melanoma, non-small cell lung cancer, pancreatic cancer, esophageal and gastroesophageal junction cancers and renal cell carcinoma in various combinations with immunotherapy, chemotherapy or radiation therapy.

On December 20, 2018 Immatics Biotechnologie reported The prospect of an actively personalized approach to the treatment of cancer has moved a step closer with the recent publication in Nature of data from the phase 1 study GAPVAC-101, testing a novel therapeutic concept tailored to specific characteristics of patients’ individual tumors and immune systems (Press release, Immatics Biotechnologies, DEC 20, 2018, View Source [SID1234569548]). For the first time, the feasibility of such a highly personalized form of immunotherapy has been exemplified in a multi-center, multi-national clinical setting.

To date, glioblastoma, an aggressive form of brain cancer with poor prognosis, and other tumor types have not sufficiently benefited from recent breakthroughs with checkpoint inhibitors due to lack of high mutational load which is thought to be essential for the mode of action of this therapeutic class. Indeed, many tumor types are characterized by a low mutational load and thus only few neoantigens are targetable by the immune system. Such cancers exhibit a high unmet medical need and require additional therapeutic strategies tailored to the features of the patient’s individual tumor and appreciating the entire breadth of the cancer target repertoire.

The Glioma Actively Personalized Vaccine Consortium (GAPVAC) approach is a highly personalized method being progressed through the GAPVAC-101 first-in-human clinical trial by a European Union-funded consortium, led by Immatics Biotechnologies GmbH (Tuebingen, Germany) and BioNTech AG (Mainz, Germany).

Fifteen newly diagnosed glioblastoma patients treated at six European centers received two immunotherapies in succession; APVAC1 targeted at non-mutated antigens, followed by APVAC2 preferentially targeted at neo-antigens. Immunotherapy compositions were personalized for each patient based on analysis of the transcriptome, immunopeptidome and mutanome of the individuals’ tumors and, for APVAC1, also based on the capability of each patient to mount an immune response. Both immunotherapy types displayed favorable safety and immunogenicity. Non-mutated APVAC1 antigens induced sustained central memory CD8+ T-cell responses, whilst APVAC2 induced T helper cell type 1 (TH1) CD4+ as well as CD8+ T-cell responses against predicted neo-epitopes.

The GAPVAC-101 trial served as a blueprint for the ACTolog IMA101-101 trial sponsored by Immatics. ACTolog is the first adoptive cell therapy trial applying the concept of active personalization.

Dr. Harpreet Singh, Chief Scientific Officer of Immatics and President & CEO of Immatics US, said: "We are at a very exciting stage in the evolution of tailor-made cancer treatments based on the diseases of individual cancer patients. The ability to exploit the full repertoire of tumor antigens, including non-mutated and neoantigens, may offer more effective immunotherapies, especially for tumors with low mutational load. And there is more to come. The next step is to translate the concept of active personalization, successfully demonstrated in this study, into adoptive cell therapies ‒ which we have achieved with the ACTolog IMA101 clinical trial Immatics is currently running at MD Anderson Cancer Center."

Prof. Hans-Georg Rammensee, Head of the Department of Immunology at the University of Tuebingen, Germany, and Co-Founder of Immatics added: "I am very pleased to see that the concept of active personalization proposed by us more than a decade ago has been applied for the treatment of glioblastoma patients. GAPVAC constitutes the first clinical trial using a combination of personalized mass spectrometry, next-generation sequencing, mRNA microarray, immune repertoire analysis and peptide GMP manufacturing for every patient and delivering these complex logistics in a multi-center multi-national clinical trial."

The approach of personalization of immunotherapies was first proposed by Prof. Hans-Georg Rammensee in 2000. His department was also responsible for the APVAC "on-demand" GMP manufacturing, led by Prof. Stefan Stevanovic, in the GAPVAC trial. The University of Tuebingen also served as one of the six European clinical trial centers treating glioblastoma patients.

On December 20, 2018 Gritstone Oncology reported that the U.S. Food and Drug Administration (FDA) has granted Fast Track designation to GRANITE-001 for the treatment of colorectal cancer (Press release, Gritstone Oncology, DEC 20, 2018, View Source [SID1234564162]). GRANITE-001 is a personalized immunotherapy containing patient-specific neoantigens identified by Gritstone’s proprietary EDGETM artificial intelligence platform as the most relevant neoantigens to drive a tumor-specific T-cell attack.

"Colorectal cancer remains a major contributor to cancer deaths and has not yet proved very amenable to first generation immunotherapy," said Andrew Allen, M.D., Ph.D., co-founder, president and chief executive officer of Gritstone Oncology. "We believe GRANITE-001 has the potential to be a valuable therapeutic option for these patients through its highly personalized design. The ability to leverage tumor markers, or neoantigens, specific to a patient’s own tumor cells in the development of a personalized immunotherapy is regarded as the next frontier of cancer therapy. We look forward to continuing our productive dialogue with the FDA under their Fast Track program as we seek to advance GRANITE-001 expeditiously for the potential benefit of patients."

The FDA grants Fast Track designation to facilitate development and expedite the review of therapies with the potential to treat a serious condition where there is an unmet medical need. A therapeutic that receives Fast Track designation can benefit from early and frequent communication with the agency, in addition to a rolling submission of the marketing application, with the objective of getting important new therapies to patients more quickly.

Ongoing Phase 1/2 Clinical Study
GRANITE-001 in combination with immune checkpoint blockade is being evaluated in a Phase 1/2 clinical study called GO-004 for the treatment of patients with common solid tumors, including metastatic non-small cell lung cancer, microsatellite stable colorectal cancer, gastroesophageal cancer, and bladder cancer. The Phase 1 study includes two parts: in part A patients receive an adenovirus-based prime with escalating doses of an RNA-based boost vaccinations in combination with anti-PD-1 therapy; and in part B patients receive the prime and the boost vaccinations at the selected dose in combination with both anti-PD-1 and anti-CTLA-4 immuno-modulatory antibodies.

About GRANITE-001
GRANITE-001 is Gritstone Oncology’s lead, personalized tumor-specific immunotherapy product candidate. It is engineered to elicit a significant T-cell response (particularly CD8+ cytotoxic T-cells) against mutation-derived tumor-specific neoantigens, or TSNA, identified for each patient through the company’s proprietary EDGE artificial intelligence platform. GRANITE-001 consists of two components, first a priming adenoviral vector followed by monthly boosting with an RNA vector, each containing the same 20 patient-specific TSNA.

As part of his presentation, Dr. Urbanski will provide a corporate update and discuss GT Biopharma’s pipeline of immuno-oncology products based off the Company’s proprietary Tri-specific Killer Engager (TriKE), Tetra-specific Killer Engager (TetraKE) and bi-specific Antibody Drug Conjugate (ADC) technology platforms.

The Company’s most advanced bi-specific ADC in development, GTB-1550, targets CD19+ and/or CD22+ hematological malignancies and is currently in the Phase 2 component of a Phase 1/2 Non-Hodgkin’s Lymphoma (NHL)/Acute Lymphocytic Leukemia (ALL) trial which is an open-label, investigator-led study. GT Biopharma expects to announce topline results from the Phase 2a trial of GTB-1550 in the first quarter of 2019.

Additionally, the Company recently announced its Investigational New Drug (IND) application to the U.S. Food and Drug Administration (FDA) is now open and it is authorized to initiate a first-in-human Phase 1 study with GTB-3550 (formerly OXS-3550), its first-in-class (TriKE), for the treatment of acute myelogenous leukemia (AML), myelodysplatic syndrome (MDS) and mastocytosis. The study, which is expected to commence in the first half of 2019, will be led by Principal Investigator, Sarah A. Cooley, MD, MS, Associate Professor, Division of Hematology, Oncology and Transplantation at Masonic Cancer Center, University of Minnesota. The Company believes that GTB-3550 could serve as a relatively safe, cost-effective, and easy-to-use therapy for refractory/relapsed AML, high-risk MDS and advanced systemic mastocytosis and could also be combined with chemotherapy and/or other agents as frontline therapy thus targeting a much larger patient population.
