As part of the research collaboration, Tmunity will work with one of the world’s leading experts in the field of neuro-oncology gene therapy, Hideho Okada, MD, PhD, a physician-scientist and professor of neurological surgery at UCSF who studies immunotherapeutic strategies aimed at malignant brain tumors. Dr. Okada has discovered and engineered a TCR that binds to and is selective for the H3.3K27M neoantigen. Recent studies have shown that the K27M mutation in the H3.3 histone is observed in more than 70 percent of DIPGs, and that gliomas harboring this mutation are associated with a poor prognosis and survival rate. In animal studies, Dr. Okada found that T cells transfected with the engineered TCR and infused into a mouse model of H3.3K27M-positive glioma harboring the K27M mutation in H3.3 had anti-tumor activity and limited toxicity in treated animals.

"This collaboration with UCSF embodies our commitment to advance novel T cell therapies into the clinic faster. Sadly, children who are diagnosed with DIPG currently have very few therapeutic options and there has been little progress in improving treatments and overall survival rates for DIPG over the last few decades," said Usman "Oz" Azam, MD, President, Chief Executive Officer and Chairperson of the Board of Tmunity. "We look forward to working with Dr. Okada and his research team to help advance this exciting discovery of a novel TCR therapy that could be a potential breakthrough in the treatment of this devastating pediatric disease, and perhaps other gliomas."

Approximately 300 children in the U.S. are diagnosed with DIPG each year, with most diagnoses occurring between five and nine years of age. Children with DIPG have a median overall survival of nine to 10 months using currently available treatments that mainly manage symptoms and complications associated with the disease.

"We are excited to join forces with Tmunity to further study the potential of our TCR T cell as a therapy for DIPG," said Dr. Okada. "The expertise Tmunity brings in clinical development, regulatory and manufacturing is invaluable as our pre-clinical research suggests that our discovery may show promise as a therapeutic approach in pediatric patients with DIPG."

The exclusive collaboration between Tmunity and UCSF brings together leading technologies and expertise from both groups to accelerate the clinical development of this novel T cell therapy. Under the terms of the agreement, Tmunity will work closely with Dr. Okada’s laboratory with the intention of moving quickly into IND-enabling studies and into the clinic. Tmunity will be responsible for leading the development, manufacturing and commercialization of the H3.3K27M TCR T cell therapy. The negotiations were led by the Technology Management team in the UCSF Innovation Ventures office, which leads the university’s business development, technology licensing, and efforts to translate cutting-edge science into therapies and products that directly benefit patients worldwide.

On January 3, 2019, Flex Pharma (the "Company") and Salarius Pharmaceuticals, LLC ("Salarius") entered into an Agreement and Plan of Merger (the "Merger Agreement") pursuant to which, among other things, Falcon Acquisition Sub, LLC, a wholly owned subsidiary of the Company, will merge with and into Salarius, with Salarius continuing as a wholly owned subsidiary of the Company and the surviving company. The Company has filed a registration statement on Form S-4 with the Securities and Exchange Commission (the "SEC") that provides additional information related to the merger. The Company is holding a special meeting of its stockholders on June 14, 2019, in order to obtain the necessary stockholder approvals to complete the merger and related matters. The merger is expected to close in the first half of 2019. The Company continues to sell HOTSHOT, its consumer product that helps to prevent and treat exercise associated muscle cramps.

The Merger Agreement (i) values Flex Pharma at $10.5 million, subject to adjustment, on a dollar-for-dollar basis, based on Flex Pharma’s net cash balance at the closing of the merger compared to a target net cash of $3.3 million, and (ii) values Salarius at $36.6 million, subject to adjustment, on a dollar-for-dollar basis, based on the sale of Series A Preferred Units pursuant to subscription agreements that Salarius entered into prior to the Merger Agreement compared to the target sale of $7.0 million of Series A Preferred Units.

Under the Merger Agreement, immediately following the effective time of the merger, Flex Pharma’s current stockholders will own approximately 19.9% of the combined company, on a partially-diluted basis, and Salarius’ current members will own approximately 80.1% of the combined company, on a partially-diluted basis.

In addition, at or prior to the closing of the merger, Flex Pharma will pay a dividend of or distribute one right per share of the Company’s common stock to its stockholders of record as of a date and time determined by the Company’s board of directors. Each right will entitle such stockholders to receive a warrant to purchase shares of Flex Pharma’s common stock ("Warrant") six months and one day following the closing date of the merger.

The aggregate value of all of the Warrants to be issued to Flex Pharma’s stockholders generally represents the difference between (i) Flex Pharma’s value per the Merger Agreement and (ii) the value of Flex Pharma’s common stock that Flex Pharma’s current stockholders will have in the combined company.

"We continue to believe that a merger with Salarius is the best opportunity for significant near- and long-term value creation for Flex stockholders. Salarius’ lead compound, Seclidemstat, is currently enrolling patients in an open-label Phase 1 dose escalation/dose expansion study in Ewing sarcoma and Salarius is also preparing to initiate additional studies in advanced solid tumors, including prostate, breast and ovarian cancers. We believe that Salarius could be poised to address significant unmet needs in oncology and we look forward to completing the merger with Salarius," stated William McVicar, Ph.D., Flex Pharma’s President and Chief Executive Officer.

"TAC01-CD19 has the potential to be a next generation solution for cell therapy for patients with different types of cancer," commented Paul Lammers, MD, MSc., President and CEO of Triumvira. "This filing is the result of an intensive preclinical development effort by the Triumvira team including the completion of the necessary IND-enabling studies as well as simultaneously preparing IND and CTA filings. We look forward to opening our first of five prominent clinical trial sites in the early summer of 2019."

Despite transformational efficacy with existing approved Chimeric Antigen Receptor T Cells (CAR-T), a significant unmet need remains due to substantial CAR-T toxicities and limited tumor types where CAR-T is effective. Triumvira is developing a proprietary T Cell Antigen Coupler (TAC) technology platform which is biologically distinct from CAR-T and has the potential to be a next generation solution to these challenges. TAC technology is a novel way to genetically modify T cells and redirect these T cells to target cancer antigens by co-opting the natural T cell receptor (TCR) to eradicate the tumor cells. TAC01-CD19 is the lead program in Triumvira’s pipeline of several TAC programs for both solid tumors and hematological malignancies.

About TAC01-CD19

TAC-01CD19 is a novel genetically engineered T cell therapy product targeting CD19 for use in B-cell malignancies. The product comprises autologous T cells that have been genetically engineered via lentiviral transduction to express the CD19 T cell Antigen Coupler (TAC). Preclinical data suggest that TAC01-CD19 has the potential for being highly efficacious with minimal side effects.

About CD19 and DLBCL

CD19 is a B cell marker and is expressed on the surface of B cell malignancies such as Diffuse Large B Cell Lymphoma (DLBCL). DLBCL is a subtype of Non-Hodgkin Lymphomas (NHLs). DLBCL is expected to impact approximately 26,000 patients in the U.S. in 2018. Even though significant improvements in therapies have occurred in the past years, about 45% of patients with DLBCL die of either their disease or of non-cancerous causes (1).

On May 1, 2019 OncBioMune Pharmaceuticals, Inc. (OTCQB:OBMP) ("OncBioMune" or the "Company"), a clinical-stage biopharmaceutical company engaged in the development of a proprietary therapeutic cancer vaccine immunotherapy and targeted cancer therapy, is reported that it has received a letter of interest from CATO BioVentures, the venture capital affiliate of Cato Holding, a privately held family fund (Press release, Oncbiomune, MAY 1, 2019, View Source [SID1234535498]).

This agreement is in support of the development plan of OncBioMune’s patented CD71-targeted chemotherapy combining paclitaxel, gallium, and transferrin, otherwise known as "PGT."

PGT is designed to deliver the chemotherapeutic agent paclitaxel to cancer cells over-expressing the transferrin receptor (aka CD71). Paclitaxel is currently FDA-approved in two forms: as solvent-based paclitaxel (sb-paclitaxel, Taxol) and protein-based paclitaxel (nab-paclitaxel, ABRAXANE).

PGT binds paclitaxel to the human protein transferrin as opposed to albumin, which is employed in nab-paclitaxel. This creates the potential to target the paclitaxel to CD71, which has been shown to be over-expressed on many different cancer types. Additionally, PGT takes advantage of the fact that the transferrin protein has binding sites for iron that can bind a different metal ion, gallium, which has anti-cancer activity. In theory, this creates a novel protein drug complex which has the capacity to deliver two, non-cross resistant cancer therapeutics in a targeted fashion.

"We are excited that CATO BioVentures has a belief in our science that would motivate them to become a strategic investor in OncBioMune. We are hopeful that this show of support from such a high quality provider will act as a catalyst to assist us in additional favorable fundraising activities," commented Dr. Brian Barnett, Chief Executive Officer at OncBioMune. "It has already been a pleasure working with the team of the CATO Research CRO arm as we start the process of putting together a clinical development plan for our proprietary therapy, PGT, and strive toward the goal of getting PGT accessible to patients with refractory cancers that represents a large area of unmet medical need."
