The Phase 1/2 study being conducted by the University of Pittsburgh School of Medicine is designed to evaluate the immunologic and potential clinical effectiveness of intensive locoregional sequential intraperitoneal (IP) cisplatin (IPC) with intravenous (iv) paclitaxel followed by peritoneal infusion of a chemokine modulatory (CKM) regimen composed of a cocktail of IP rintatolimod and interferon-alpha (IFNα) for patients with advanced stage ovarian cancer (III-IV) at primary neoadjuvant setting. AIM ImmunoTech provided rintatolimod (Ampligen, a dsRNA acting as TLR3 agonist), for the Phase 1/2 study.

"These results represent an important extension of prior studies using human tumor explants that showed Ampligen’s potentially important role as a TLR3 agonist acting synergistically with high-dose IFNα and celecoxib to selectively enhance Teff cell-attractants while suppressing Treg-attractants in the tumor microenvironment with a concomitant increase in the Teff/Treg ratio. This current study shows that similar findings are seen combining Ampligen with chemokine-targeting and chemo-immunotherapy in patients being treated for recurrent ovarian cancer. The importance of boosting the Teff/Treg ratio in the tumor microenvironment is that it is associated with the conversion of ‘cold’ tumors into ‘hot’ tumors, which have an increased sensitivity to chemo-immunotherapy and an improved chance of showing tumor regression. This, of course, creates the potential for a positive survival advantage," stated David Strayer, MD, Chief Medical Officer, Chief Scientific Officer of the Company and Board Certified in Medical Oncology.

1 Clin Cancer Res January 19 2022 DOI: 10.1158/1078-0432.CCR-21-3659

Thomas Equels, Chief Executive Officer of AIM commented, "We are very pleased with these results. Ampligen has demonstrated broad immunological effects and we believe has the potential to be a key component in the treatment of ovarian cancer. We are grateful to the University of Pittsburg School of Medicine and are excited to provide support for a larger Phase 2 study which we believe has the potential to provide hope for patients and their families, as well as drive significant shareholder value."

Twelve patients were enrolled in Phase 1 portion of the trial and were treated with IP cisplatin, IP Ampligen, and oral celecoxib (COX-2 blocker). Patients in cohorts 2, 3 and 4 also received IP IFNα at 2, 6 and 18 million units, respectively. The primary objectives of the study were to evaluate safety, identify Phase 2 recommended dose and characterize changes in the immune TME. Peritoneal resident cells and IP wash fluid were profiled via NanoString and Meso Scale Discovery (MSD) multiplex assay, respectively.

Of the 12 patients enrolled in this Phase 1 trial, 9 (75%) were evaluable for safety, toxicity, and other endpoints. The 3 non-evaluable patients did not complete at least 3 cycles, due to platinum hypersensitivity reactions or port complications. Overall, the regimen was well tolerated, apart from the highest dose of IFNα. Most common toxicities for all grades were anemia (58%), hypomagnesemia (50%), hyponatremia (41.7%), arthralgia (41.7%), and fatigue (41.7%). There was one grade 4 hypomagnesemia (8.3%). Dose limiting toxicities of abdominal pain of grade 3 or more were noted in two patients who received 18MU IFNα (cohort 4).

The Phase 2 recommended dose of IFNα was 6 million units every 3 weeks. Median PFS was 8.4 (3-16.4) months. Median overall survival was 30 (8-66) months. The Company believes these survival outcome data provide an encouraging early signal. Overall response rate was 55.6% and the disease control rate (DCR) was 77.8%, consistent with the expected platinum-sensitive response. Among responders, median duration of response was 11.7 (6-16.4) months.

Key Results Highlights

●Determination of the safety profile and identification of Phase 2 recommended dose for the combination of local cisplatin, Ampligen and IFNα, with oral celecoxib;
●Chemo-immunotherapy combination triggers robust transcriptomic changes in peritoneal resident cells obtained in lonitudinal sampling via IP washes;
●Protein content of IP wash fluid captures treatment-induced increases of IFN-induced immune effector molecules; and
●Tumor immune profile at interval debulking shows partial overlap with IP wash, and points to upregulation of genes encoding for perforin and granzyme B.

Longitudinal sampling of the peritoneal cavity via IP washes demonstrated local upregulation of interferon-stimulated genes, including CTL-attracting chemokines (CXCL-9, -10, -11), MHC I/II, perforin and granzymes. These changes were present two days post chemokine modulation and subsided within one week.

"Epithelial ovarian cancer, the most common form of ovarian cancer, is the most aggressive gynecologic cancer and despite aggressive surgery and chemotherapy treatment options, the 5-year survival rate for patients with advanced high grade serous ovarian cancer remains low. I am very encouraged by the results from this study. With our growing body of positive data, I look forward to further advancing development of this important program with the hope of addressing the significant unmet medical need," added Robert P. Edwards MD, Milton McCall Professor and Chairman, Department of Obstetrics, Gynecology, and Reproductive Sciences, University of Pittsburgh School of Medicine, Director of Women’s Health for UPMC.

Based on these encouraging results, the Company plans on supporting a follow-up Phase 2 trial that will specifically define the immunologic and clinical efficacy of tumor loaded αDC1 vaccine in conjunction with the cisplatin/chemokine modulatory combination regimen will be conducted.

SQZ-eAPC-HPV is created by delivering five different mRNAs into a patient’s monocytes, B cells, T cells, and NK cells – engineering four cell types with five functions in a single step. In preclinical models, SQZ eAPCs have been shown to generate robust CD8 T cell responses against multiple antigens, including HPV16 proteins, through simultaneous expression of antigens, CD86, membrane bound IL-2, and membrane bound IL-12.

"We believe SQZ eAPCs represent a major advance in cell therapy with the largest number of multiplexed components ever advanced into clinical testing. We are incredibly excited to explore its potential for patient impact," said Armon Sharei, Ph.D., Chief Executive Officer and Founder of SQZ Biotechnologies. "SQZ eAPCs build upon the promising preliminary monotherapy clinical activity shown by our first SQZ APC platform. Through multiplexed engineering of a patient’s monocytes, B cells, T cells, and NK cells, we are able to integrate antigen presentation and enhanced immunological functions into a single clinical candidate that could become a powerful weapon against solid tumors."

By focusing on engineering physiological mechanisms, SQZ cell therapies do not require patient pre-conditioning and have thus far been well tolerated in clinical study. Similar to our other clinical programs, SQZ eAPCs can be manufactured in under 24 hours and have the potential for future implementation on our point-of-care platform.

The SQZ eAPC trial is the third FDA IND clearance for a clinical candidate based on the company’s Cell Squeeze technology.

About SQZ-eAPC-HPV

SQZ Enhanced Antigen Presenting Cells (eAPC) are derived from peripheral blood mononuclear cells (PBMCs), which are primarily composed of monocytes, T cells, B cells, and

img61662729_0.jpgEmpowering Cells to Change Lives

NK cells, and engineered with various mRNA encoding for multiple target antigens and immuno-stimulatory signals, including CD86 and membrane bound IL-2 and IL-12. The company presented preclinical findings in November 2021 at the Society for Immunotherapy of Cancer (SITC) (Free SITC Whitepaper) showing that SQZ eAPCs generated robust T cell responses in human in-vitro models. Additionally, it was demonstrated that HPV16-encoding mRNA delivery to PBMCs stimulated CD8+ T cells across a range of HLA haplotypes, supporting eAPC clinical development in broad HPV16+ patient populations.

COMMANDER-001 Trial Design

SQZ-eAPC-HPV is being evaluated in a Phase 1/2 clinical trial (COMMANDER-001) for the treatment of HPV16+ advanced or metastatic solid tumors. The investigational candidate, which targets E6 and E7 oncoproteins, is being studied as a monotherapy and in combination with pembrolizumab, an immune checkpoint inhibitor. The study consists of two parts. The first part is designed to assess safety and tolerability of multiple doses of SQZ-eAPC-HPV in treatment-experienced patients, following a dose escalation scheme for monotherapy, and a dose de-escalation for the combination with pembrolizumab. The second part of the study will assess clinical response in less treatment-experienced patient populations.

About Human Papillomavirus Positive Cancers

Human papillomavirus (HPV) is one of the most common viruses worldwide and certain strains persist for many years leading to cancer. According to the Centers for Disease Control (CDC), in the United States HPV+ tumors represent 3% of all cancers in women and 2% of all cancers in men, resulting in over 39,000 new cases of HPV+ tumors every year. HPV infection is larger outside of the U.S., and according to the International Journal of Cancer HPV+ tumors account for 4.5% of all cancers worldwide, resulting in approximately 630,000 new cases every year. According to the CDC, HPV infection plays a significant role in the formation of more than 90% of anal and cervical cancers, and most cases of vaginal (75%), oropharyngeal (70%), vulval (70%) and penile (60%) cancers.

On January 24, 2022 MaaT Pharma (EURONEXT: MAAT – the "Company"), a French clinical-stage biotech and a pioneer in the development of microbiome-based ecosystem therapies dedicated to improving survival outcomes for patients with cancer, reported that positive interim engraftment data from the first four cohorts of the CIMON trial with MaaT033, the Company’s high-richness, high-diversity, Microbiome Ecosystem Therapy for oral administration (Press release, MaaT Pharma, JAN 24, 2022, View Source [SID1234606708]).

In this dose-ranging study, data from four out of five intended cohorts showed satisfactory safety and good microbiome engraftment, which is characterized by the presence of microbial OTUs[1] in the gut as a result of product administration and that were not present at treatment start.

Based on this positive data, the Company will close the CIMON trial to enable faster than planned completion and evaluation of the full data from the trial, in order to advance MaaT033 towards a planned Phase 2/3 trial, which could start in the second half of 2022. Complete results from the Phase 1b CIMON trial are expected in the first half of 2022.

"These interim results are an important milestone for MaaT Pharma as MaaT033 is our second product, and our first oral formulation, to demonstrate proof of engraftment in humans. This expands the potential of our proprietary Microbiome Ecosystem Therapy (MET) platform to the ambulatory setting, after positive data achieved in aGvHD with MaaT013, an enema product for acute, hospital use. This is the first step towards treating larger patient populations that may benefit from orally-administered microbiome therapies, including patients receiving allo-HSCT, but also patients with solid tumors."

said Hervé Affagard, CEO and co-founder of MaaT Pharma.

MaaT033 is intended to improve survival outcomes in hemato-oncology patients receiving allo-HSCT by protecting and restoring their gut microbiome. In these patients, intensive chemotherapy and antibiotic treatments that are administered to prepare for the allo-HSCT procedure result in a severely damaged gut microbiome. Importantly, higher gut microbiome diversity at the time of allo-HSCT has been correlated to higher survival and lower risks of complications, including incidence of graft-vs-host-disease and multi-resistant infections[2].

"With a very satisfactory safety profile and very promising engraftment data in the first four cohorts of this trial, we believe we have the appropriate amount of data in hand to confidently move forward with MaaT033’s clinical development, without testing the highest planned dose of nine capsules a day. We look forward to further exploring the data from CIMON and preparing for a Phase 2/3 trial start."

added John Weinberg, MD, Chief Medical Officer at MaaT Pharma.

The CIMON Phase 1b trial (NCT04150393) is an open-label, dose-ranging study and has enrolled to date a total of 21 patients in four cohorts (up to three capsules a day for 14 days) across six sites in France. CIMON is designed to investigate the maximum tolerated dose of MaaT033, over 7 or 14 days of therapy, that supports optimal gut microbiome colonization in patients with acute myeloid leukemia or high-risk myelodysplastic syndrome who have undergone intensive chemotherapy. Overall, four Data and Safety Monitoring Board meetings have been conducted evaluating the safety of the trial. All concluded in support of the continuation of the study with the latest taking place in December 2021. Complete results from the trial will be submitted for a presentation at an upcoming key major conference in hemato-oncology as well as for peer-reviewed publication.
