The article titled, "Post-translational covalent assembly of CAR and synNotch receptors for programmable antigen targeting," describes key advances in antigen receptor design to develop "universal" receptor systems for diverse programming of cell behaviors using covalent chemistry. Using in vitro and in vivo models, the authors demonstrated that the SNAP-CAR platform provides a powerful adaptor strategy for fully programmable targeting of engineered cells to multiple antigens. Further, it was concluded that these systems have the potential for clinical application and biotechnological utility by providing researchers with the ability to rapidly screen CAR and synNotch antibody candidates and to rewire and activate cellular programs in response to highly specific antibody-antigen interactions.

"This research highlights key advances in antigen receptor design, including the creation of a universal adaptor synNotch system and a universal CAR system that act through self-labeling enzyme chemistry, representing a potential breakthrough in programmable antigen targeting," said Jason Lohmueller, Ph.D., Assistant Professor of Surgery and Immunology in the Division of Surgical Oncology Research, University of Pittsburgh. "These ‘universal’ receptor systems, for which receptor specificity can be directed post-translationally via covalent attachment of a co-administered antibody, offer the potential to allow for one population of T cells to target multiple tumor antigens, enabling the development of cell therapies for a wide range of cancers, including hematologic and solid tumors."

"SNAP-CAR represents a powerful technology with the potential to be engineered to address numerous cancers, including HER2-expressing cancer, which we are targeting as our potential first-in-human clinical development program," said Dave Mehalick, President and CEO of Coeptis Therapeutics. "Having research on SNAP-CAR published in such a prestigious scientific journal as Nature Communications provides further validation of the technology’s potential and the groundbreaking work being conducted by Dr. Lohmueller and his team at the University of Pittsburgh."

About SNAP-CAR
SNAP-CAR, which Coeptis Therapeutics licensed from the University of Pittsburgh, is designed to be a "universal" CAR T cell therapy platform that can be adapted to different cancer indications. Instead of directly binding to a target on the tumor cell, CAR T cells are co-administered with one or more antibody adaptors that bind to the tumor cells and are fitted with a chemical group that irreversibly connects them to the SNAP-CAR on the therapeutic cells via a covalent bond. Pre-clinical studies in mice have demonstrated that by targeting tumors via antibody adaptor molecules, the SNAP-CAR therapy provides a highly programmable therapeutic platform.

On May 10, 2023 Transgene (Euronext Paris: TNG), a biotech company that designs and develops virus-based immunotherapies for the treatment of cancer, reported a business update, including its financial position as of March 31, 2023 (Press release, Transgene, MAY 10, 2023, View Source [SID1234631412]).

Key events and upcoming milestones

Since the beginning of the year, all of Transgene’s clinical and preclinical assets have progressed in line with expectations. Promising data were presented on all clinical-stage immunotherapies at the AACR (Free AACR Whitepaper) 2023 conference (April 2023). New data will be communicated in Q2 2023 on TG4001, TG4050 and BT-001.

Therapeutic cancer vaccines

TG4001: New data to be presented at the ASCO (Free ASCO Whitepaper) 2023 conference — Preparing for a planned potentially registrational trial in an HPV-positive indication

Transgene anticipates that the last patient will be randomized in the current Phase II clinical study in the first half of 2024. This study is comparing TG4001 in combination with avelumab vs avelumab alone in patients with HPV16-positive anogenital tumors. Final results will be communicated in 2024.

A trial-in-progress poster was presented at the AACR (Free AACR Whitepaper) conference in April 2023. New translational data from TG4001 will be presented in another poster at the upcoming ASCO (Free ASCO Whitepaper) conference (June 2–6, 2023). Transgene is working on the design of a potentially registrational trial to further confirm the benefit of this novel therapeutic cancer vaccine.

TG4050: Strong clinical potential confirmed by initial data from the two ongoing Phase I trials — Transgene is preparing a Phase II trial in head and neck cancers

New data were presented on TG4050 at AACR (Free AACR Whitepaper) 2023. These data show that this individualized neoantigen cancer vaccine is able to induce strong immune responses, which are expected to result in longer remission periods for patients.

All evaluable patients developed a specific immune response against multiple cancer neoantigens after treatment with TG4050 and remained disease-free in the head and neck cancer trial. These data suggest that TG4050 can boost the immune system of patients in the absence of pre-existing response and despite a challenging tumor micro-environment at baseline.

Transgene hosted a key opinion leader (KOL) event with the participation of Professor Christian Ottensmeier, MD, PhD, FRCP (University of Liverpool, La Jolla Institute for Immunology) who highlighted the medical need in head and neck cancer and the potential of a virus-based immunotherapy such as TG4050.

Transgene expects the last patient to be treated in the Phase I study in head and neck cancer in the coming weeks. Final results from this trial are expected mid-2024.

Transgene and NEC are preparing for a Phase II trial in head and neck cancers which could be initiated in H2 2023.

Transgene will present new data from TG4050 at the upcoming ASCO (Free ASCO Whitepaper) conference in June.

Oncolytic Viruses

TG6002: New data presented at AACR (Free AACR Whitepaper) support the potential of intravenous administration (IV) of Invir.IO-based oncolytic viruses, which offers a competitive advantage

Clinical data presented at AACR (Free AACR Whitepaper) 2023 confirmed the mechanism of action and the safety of our Invir.IO based oncolytic viruses, which offers a key competitive advantage.

These findings support the potential of Invir.IO-based oncolytic viruses to be given by IV administration. This extends their potential use to a much broader range of solid tumors. At present, the use of oncolytic viruses is limited by their intratumoral administration.

BT-001: Ongoing Phase I trial — Monotherapy data expected in H1 2023

Transgene and BioInvent intend to communicate data from the Part A (monotherapy) of the ongoing Phase I trial in H1 2023. The Part B of the Phase I trial (in combination with pembrolizumab) is expected to start in the second half of 2023. KEYTRUDA (pembrolizumab) will be provided to the trial by MSD (Merck & Co).

TG6050: First patient treated with novel Invir.IO candidate designed to express IL-12 and be administered intravenously

In early 2023, Transgene announced the regulatory approval to initiate a clinical trial of TG6050, a novel oncolytic virus from its Invir.IO platform. This innovative candidate has been designed to express human IL-12, a cytokine known to trigger a potent antitumor immune response, and an anti-CTLA4 antibody.

The Delivir trial is evaluating TG6050 in patients with advanced non-small cell lung cancer who have failed standard therapeutic options. The first patient has been dosed. Completion of the trial is expected in H2 2024.

AstraZeneca collaboration update

As previously announced on 5 May 2023, the Company was informed by AstraZeneca of its decision to terminate its oncolytic virus research and development collaboration with Transgene that was signed in 2019. The decision was made by AstraZeneca following a strategic review of its pipeline. Following termination, Transgene will regain the global rights to the oncolytic virus drug candidate that was in-licensed by AstraZeneca in December 2021. This intravenous drug candidate has been granted a US IND.

"iTeos is entering 2023 from a position of strength. We are thoughtfully and methodologically advancing both our lead programs through clinical development to fully unlock their potential. Notably, we’re focused on progressing our multiple clinical studies with belrestotug and GSK’s Jemperli (dostarlimab), with continuing clinical development with both doublet and novel triplets. This includes the ongoing preparations for our first Phase 3 study in first line non-small cell lung cancer with the doublet of belrestotug and dostarlimab, which we are targeting for study initiation by the end of the year. For our adenosine pathway programs, we also remain on track with our first-in-class small molecule program EOS-984, as it enters the clinic in the near term. These advancements follow recently presented biomarker data at the American Association for Cancer Research (AACR) (Free AACR Whitepaper) meeting, which have expanded our understanding of the mechanisms of adenosine-mediated immunosuppression, opening up avenues to new patient selection strategies," said Michel Detheux, Ph.D., president and chief executive officer of iTeos. "Looking ahead, we will continue to leverage our expertise in tumor biology alongside our ability to evaluate novel combinations with our therapeutic candidates, as we continue to execute on our mission to bring a new generation of treatment options to those living with cancer."

Program Highlights:

Belrestotug (EOS-448/GSK4428859A): IgG1 anti-TIGIT monoclonal antibody designed to engage the Fc gamma receptor (FcγR) and enhance the anti-tumor response through multifaceted mechanisms.

In collaboration with GSK, late-stage development of belrestotug as a potential next-generation immuno-oncology agent through multiple combination studies is on track. Highlights include:
Ongoing randomized Phase 2 trial assessing the doublet of dostarlimab with belrestotug in previously untreated advanced / metastatic non-small cell lung cancer (NSCLC).
Ongoing Phase 2 expansion study assessing the doublet of dostarlimab with belrestotug in first line advanced or metastatic head and neck squamous cell carcinoma.
Phase 1b trials ongoing exploring two novel triplets in selected advanced solid tumors: belrestotug with dostarlimab and GSK’s investigational anti-CD96 antibody, and belrestotug with dostarlimab and GSK’s investigational anti-PVRIG antibody.
Continued advancement of the monotherapy dose escalation part of a Phase 1/2 trial evaluating belrestotug as both a monotherapy and in combination with Bristol Myers Squibb’s iberdomide in multiple myeloma.
Adenosine Pathway
Inupadenant (EOS-850): Designed as an insurmountable and highly selective small molecule antagonist of the adenosine A2A receptor, the only high-affinity adenosine receptor expressed on multiple immune cells found in the tumor microenvironment. Highlights include:

Progression of the ongoing two-part Phase 2 trial in post-IO metastatic non-squamous NSCLC to evaluate the combination of inupadenant with platinum-doublet chemotherapy compared to standard platinum-doublet chemotherapy.
Data describing a novel mechanism of action of inupadenant in tumor tissue was presented at the American Association for Cancer Research (AACR) (Free AACR Whitepaper) meeting in April 2023. Translational analysis of tumor material from inupadenant clinical trials demonstrated that the predominant cell type in tumor tissue expressing high levels of the target A2A receptor were in fact antibody secreting cells. Additionally, these cells were shown in vitro to be suppressed by adenosine and that such suppression could be reversed by inupadenant.
EOS-984: First-in-class small molecule program targeting a novel mechanism in the adenosine pathway.

This complementary clinical development program has the potential to fully reverse the profound immunosuppressive action of adenosine on T and B cells. EOS-984’s effects have been shown preclinically to be enhanced by combining with inupadenant and other standards of care.
The company completed Investigational New Drug / Clinical Trials Application-enabling activities, including toxicity studies, and anticipates initiating clinical studies for EOS-984 mid-year 2023.

TG6050 seeks to overcome tumor resistance by initiating an antitumor response through multiple mechanisms of action that include oncolysis, the induction of an immune response together with high intra-tumoral concentrations of IL-12 and anti-CTLA4 antibody.

The Delivir trial will enroll up to 36 patients with advanced NSCLC who have failed standard therapeutic options, including immune checkpoint inhibitors. The IV route is considered the most appropriate route of administration for this patient population with disseminated disease and multiple overt and occult metastases. Completion of the trial is expected in H2 2024.

The potential for IV administration of Transgene’s patented Invir.IO platform has been seen in the data presented for TG6002. TG6050 will build on the safety profile of Transgene’s backbone while enhancing the therapeutic potential of its two highly immunogenic payloads – IL-12 and a full length anti-CTLA-4 antibody – while limiting exposure to their systemic toxicity.

"We are pleased to initiate this first-in-human trial of TG6050 administered intravenously in patients with recurrent/metastatic advanced non-small cell lung cancer in great need for effective new therapeutic options," said Dr. Maud Brandely, MD, PhD, Chief Medical Officer of Transgene. "Intravenous administration of TG6050 aims at significantly enhance the therapeutic potential of this promising oncolytic virus as it allows a targeted approach to many internal cancer lesions and metastases inaccessible by intratumoral injection. With its multiple mechanisms of action – including oncolysis, the induction of an immune response together with high intra-tumoral concentrations of IL-12 and anti-CTLA4 antibody – and its ability to be administered intravenously, TG6050 has several competitive advantages. We look forward to progressing this trial and delivering clinical results for this promising new oncolytic virus."

Efficacy and safety of TG6050 were demonstrated in preclinical and toxicology studies in non-human animal models. Initial data were presented at the American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting, April 14 -19, 2023 and can be accessed here.

About the Delivir trial (NCT: NCT05788926)

The Delivir trial is a multicenter, open label, dose-escalation Phase I trial evaluating TG6050 as a single agent. The trial will enroll up to 36 patients with metastatic/advanced non-small cell lung cancer (NSCLC), who have failed standard therapeutic options including immunotherapies such as immune checkpoint inhibitors. Patients will receive single and repeated escalating doses of TG6050 administered intravenously, to determine the recommended dose and best schedule of administration for subsequent clinical development.

About TG6050

TG6050 is an oncolytic virus developed with Transgene’s Invir.IO platform for intravenous administration. Invir.IO’s viruses are based on the patented large capacity Vaccinia virus Copenhagen strain genetically modified with the double deletion TK-RR- (VVCOPTK-RR-). TG6050 has been engineered to encode human IL-12, a cytokine that triggers a powerful antitumor immune response and a full length anti-CTLA4 antibody. It has also been optimized with the deletion of the gene encoding for the M2L viral protein that targets CD80 and CD86, two ligands of CTLA4 [source: Kleinpeter et al., J Virol. 2019 Jun 1; 93(11): e00207-19]. The use of an oncolytic virus to deliver these immunotherapies locally and selectively in the tumor microenvironment allows high intratumoral concentrations of both therapeutic proteins eliciting a stronger and more effective antitumor response. By reducing systemic exposure to a very low level, this local therapeutic activity furthermore allows to increase the safety and tolerability profile of IL-12 and the anti-CTLA4 antibody.
It is evaluated in the Delivir trial, a Phase I trial conducted in advanced NSCLC patients.
A short video detailing TG6050’s mechanism of action can be found here.
