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.

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]). These results represent the first confirmation of MaaT033’s mechanism of action in humans.

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.

"The completion of enrollment of the AGI-134 first-in-man study is a very significant milestone for our Company, especially taking into account the difficulties caused by the COVID-19 pandemic on patient recruitment," stated Philip Serlin, Chief Executive Officer of BioLineRx. "AGI-134, our second clinical-stage oncology asset, has a unique mode of action, applicable to all injectable tumor types. In preclinical models, AGI-134 led to regression of primary tumors, prevented growth of secondary tumors via an abscopal effect, and triggered a vaccine effect that we believe may prevent the development of metastases. This clinical study aims to confirm the proposed mechanism of action and safety profile of AGI-134 in humans, based on which we also plan to explore potential combinations as part of its future clinical development program."

The Phase 1/2a study is a multicenter, open-label study, which recruited a total of 38 patients in the UK, Spain and Israel, and is comprised of two parts. Part 1 was completed, and was an accelerated dose-escalation study in five patients, to determine the maximum tolerated dose and the recommended dose for part 2 of the study. Part 2 is a dose expansion study at the recommended dose in 33 patients, designed to evaluate the safety and tolerability of AGI-134, and to validate AGI-134’s mechanism of action using a wide array of biomarkers. For more information on this Phase 1/2a study, see NCT03593226.

On December 15, BioLineRx announced the formation of an Immuno-Oncology Scientific Advisory Board (SAB) to provide insight and guidance on the Company’s immuno-oncology activities. The SAB, which has provided valuable guidance to the AGI-134 development program, is comprised of recognized key opinion leaders in the fields of cancer immunology, intra-tumoral cancer treatments and clinical development.

About AGI-134
AGI-134 is a synthetic alpha-Gal glycolipid in development for solid tumors that is highly differentiated from other cancer immunotherapies. AGI-134 is designed to label cancer cells with alpha-Gal via intra-tumoral administration, thereby targeting the body’s pre-existing, highly abundant anti-alpha-Gal (anti-Gal) antibodies and redirecting them to treated tumors. Binding of anti-Gal antibodies to the treated tumors results in activation of the complement cascade, which destroys the tumor cells and creates a pro-inflammatory tumor microenvironment that also induces a systemic, specific anti-tumor (vaccine) response to the patient’s own tumor neo-antigens.

AGI-134 has been evaluated in numerous pre-clinical studies. In a mouse melanoma model, treatment with AGI-134 led to regression of established primary tumors and suppression of secondary tumor (metastases) development. Synergy has also been demonstrated in additional pre-clinical studies when combined with an anti-PD-1 immune checkpoint inhibitor, offering the potential to broaden the utility of such immunotherapies, and improve the rate and duration of responses in multiple cancer types. AGI-134 was obtained by BioLineRx through the acquisition of Agalimmune Ltd.
