This work will expand on the recently published results from the Kiessling group demonstrating that an sd-rxRNA targeting PD-1 can enhance TIL antitumor activity against melanoma cells in vitro, further showing that ex vivo treatment with the sd-rxRNA compounds was easily incorporated into a clinically relevant rapid expansion protocol for TILs.1

Dr. Gerrit Dispersyn, Chief Development Officer of RXi Pharmaceuticals, stated: "We are pleased to expand our collaboration with Dr. Kiessling’s group, to further harness their expertise in oncology and to expand on the successful research they have previously done with our sd-rxRNA technology platform in immuno-oncology. The combination of their prior results and the anticipated research results from this new collaboration are critical elements for a rapid advancement of sd-rxRNA immuno-oncology therapeutics into the clinic, further supported by our prior clinical experience with sd-rxRNA in other indications."

Rolf Kiessling, MD, PhD, Senior Professor in Experimental Oncology at the Karolinska Institutet, Senior Chief Physician at the Oncology clinic at the Karolinska University Hospital and member of RXi’s Scientific Advisory Board stated: "Our results to date provide direct clinical relevance for the use of sd-rxRNA technology to improve ACT. In this collaboration, we look forward to exploring using sd-rxRNA to modulate targets outside of checkpoints to improve efficacy of immune effector cells such as T cells and NK cells."

Immunotherapy of cancer has become increasingly important in clinical practice over the recent decade. By activating the patient’s immune system, immunotherapy treatments have shown remarkable promise in extending the lifespan of previously untreatable cancer patients. Adoptive cell therapy is an emerging immunotherapy approach which uses immune cells, such as T-lymphocytes or NK cells that are isolated from the patient or retrieved from allogeneic immune cell banks, and then expanded and in some cases processed to express tumor-binding receptors.

A new and important step in this ex-vivo processing of the immune cells is in development where self-delivering RNAi compounds (sd-rxRNA) are used to eliminate the expression of immunosuppressive receptors or proteins from the therapeutic immune cells, thereby making them less sensitive to tumor resistance mechanisms and improving their ability to destroy tumor cells. In this way, sd-rxRNA therapeutic compounds can be used to weaponize therapeutic immune cells to attack cancer and ultimately provide patients battling terminal cancers with a powerful new treatment option that goes beyond current treatment modalities.

About RXi Pharmaceuticals

RXi Pharmaceuticals Corporation (NASDAQ: RXII) is a biotechnology company developing the next generation of immuno-oncology therapeutics based on its self-delivering RNAi (sd-rxRNA) therapeutic platform. The Company’s discovery and research efforts are focused on developing sd-rxRNA therapeutic compounds to be used with an Adoptive Cell Transfer (ACT) approach. This process uses immune cells, such as T-lymphocytes that are isolated from the patient or retrieved from allogeneic immune cell banks, and then expanded and in some cases processed to express tumor-binding receptors. Our approach introduces a new and important step in ex-vivo processing of the immune cells where sd-rxRNA is used to eliminate the expression of immunosuppressive receptors or proteins from the therapeutic immune cells, making them less sensitive to tumor resistance mechanisms and thus improving their ability to destroy the tumor cells. Essentially, we aim to maximize the power of our sd-rxRNA therapeutic compounds by weaponizing therapeutic immune effector cells to attack cancer and ultimately provide patients battling terminal cancers with a powerful new treatment option that goes beyond current treatment modalities.

Jeff Wolf, Heat’s CEO, commented, "Earlier this year we reported positive interim results from our Phase 2 trial investigating HS-110 in combination with Bristol-Myers Squibb’s anti-PD-1 checkpoint inhibitor, nivolumab (Opdivo), in patients with advanced non-small cell lung cancer (NSCLC). Since then, we have continued to execute on our clinical plan and remain on track to report additional interim Phase 2 data in the fourth quarter of 2018 and to complete trial enrollment in Q2 2019."

"In addition to our Phase 2 HS-110 program, we look forward to filing our Investigational New Drug (IND) application to initiate a Phase 1 clinical trial for our ComPACT trial in the fourth quarter of 2018. Our ComPACT therapy combines T-cell activators and co-stimulators within a single treatment, simplifying combination immunotherapy while providing superior immune activation and reduced treatment costs."

"Finally, we look forward to filing our second Investigational New Drug (IND) application to initiate a Phase 1 clinical trial for PTX-35, a novel co-stimulatory monoclonal antibody, in the first quarter of 2019. Each of our therapies is designed to enhance the response rate for patients least likely to respond to checkpoint inhibitors through a combination treatment that enhances the immune defense mechanisms."

"Importantly, we completed a capital raise of $20.7 million in the second quarter of 2018. In addition, we have subsequently generated an additional $4.8 million through the exercise of warrants. These funds, combined with the additional $6.9 million in CPRIT grant funds for PTX-35, which we expect to receive in the third quarter of this year, should provide us sufficient capital to advance our clinical programs and achieve a number of major milestones through the end of 2019."

Clinical and Corporate Developments included:

CEL-SCI’s Phase 3 head and neck cancer study continued to follow all 928 patients. Enrollment was completed in September of 2016. Based on published survival data, we believe top line results may be available as soon as early 2019. All that remains to be done in this pivotal Phase 3 study, the largest in the world in head and neck cancer, is to continue to track patient survival until it can be determined if the primary endpoint has been met. The primary endpoint of the study, a 10% improvement in overall survival of the Multikine treatment regimen plus Standard of Care (SOC) vs. SOC alone, will be determined after a total of 298 deaths have occurred in the two main comparator arms of the study and have been recorded in the study database.
The US Patent and Trademark Office allowed two new patents to CEL-SCI for the Company’s LEAPS platform technology. Titled "Method for Inducing an Immune Response and Formulations Thereof" and " Method for Inducing an Immune Response against avian, swine, Spanish, H1N1, H5N9 influenza viruses and formulations", these patents relate to methods for diagnosing, preventing, and treating disease by generating or modulating the immune response through the use of specific peptides.
CEL-SCI won the arbitration against the clinical research organization (CRO) that ran the Phase 3 head and neck cancer study from 2011-2013. The arbitrator ruled that the CRO materially breached its contract with CEL-SCI. The arbitrator’s decision has vindicated CEL-SCI. Many investment funds and analysts did not like the legal risk of this arbitration and now that the arbitration has been resolved in CEL-SCI’s favor, this should no longer be an impediment to investors and should result in renewed investment interest in CEL-SCI. With the arbitration completed, CEL-SCI moves forward with a clean slate.
"We are proud of having run the largest head and neck cancer Phase 3 study in the world, in an indication that has not seen a new drug approved by the FDA in over 60 years. This has not been easy for many reasons, including the fact that our approach to immunotherapy involves treating the patient when they first get diagnosed instead of using immunotherapy as a last ditch option for survival. Our approach meant a longer clinical trial period, with nearly one thousand patients enrolled. Despite the many challenges of this study, we believe the potential to bring a new immunotherapy to help save the lives of newly diagnosed cancer patients has been worth it," said CEL-SCI’s Chief Executive Officer, Geert Kersten. "As we look forward to a readout of the endpoint data which may happen in early 2019, we also continue to develop our LEAPS technology platform with the support of the U.S. National Institutes of Health. Should our Phase 3 results lead to marketing approval in head and neck cancer, we will also have the opportunity to purse clinical development and marketing approval of our immunotherapy in other cancer indications."

During the nine months ended June 30, 2018, the Company’s cash remained constant. Cash used in operations of approximately $9.1 million was offset by approximately $9.1 million in cash provided by financing activities. Sources of financing during the nine months included approximately $7.0 million in proceeds from the issuance of common stock and warrants and $2.1 million in proceeds from the exercise of warrants.

CEL-SCI reported an operating loss of ($4,070,363) for the quarter ended June 30, 2018 versus an operating loss of ($4,758,719) for the quarter ended June 30, 2017. The operating loss was ($13,187,538) for the nine months ended June 30, 2018 versus an operating loss of ($17,603,283) for the nine months ended June 30, 2017.
