ART4215 is the first selective, oral, small molecule inhibitor of the Polθ polymerase domain to enter the clinic. Polθ, a DNA polymerase, is a tumor-specific DDR target involved in microhomology mediated end joining (MMEJ) that is overexpressed in many tumors and found in low levels in healthy tissue. Extensive preclinical studies have demonstrated that ART4215 has broad potential clinical utility, as described in Artios’ recent Nature Communications publication, Zatreanu et al., 2021. The Polθ project was originally in-licensed from Cancer Research Technology (now Cancer Research Horizons) in 2016 as part of the initial formation of Artios.

Dr. Niall Martin, Chief Executive Officer at Artios, said: "Polθ is highly expressed in cancer cells, but has limited expression in healthy cells, making it an attractive cancer target. Initial Phase 1 data supports a favorable tolerability profile and the potential for broad treatment use, particularly in combination with agents like PARP inhibitors where combinations with other DNA damage response inhibitors have been limited by toxicity. We are highly encouraged that ART4215 may offer a new treatment option that can synergize to overcome both de novo and acquired PARP resistance. We look forward to reporting Phase 1 safety and tolerability data in the first half of 2023."

Principal Investigator for the trial, Dr. Erika P. Hamilton, Director of the Breast Cancer and Gynecologic Cancer Research Program, Sarah Cannon Research Institute at Tennessee Oncology, said: "Patients with advanced solid tumors have achieved improved outcomes with the development of PARP inhibitors. However, there is still a need to address resistance mechanisms diminishing initial tumor responses and leading to disease progression. ART4215 has the potential to help overcome these limitations, and we are excited that the initiation of this Phase 2 trial represents an important step in the clinical evaluation of Polθ as a novel target."

ART4215 is currently being evaluated in an ongoing, first-in-human, global, open-label Phase 1/2 study to assess the safety, tolerability, pharmacokinetics, and clinical activity of ART4215 as a monotherapy or in combination with talazoparib in patients with advanced or metastatic solid tumors. Initial safety data from the first Phase 1 dose cohorts have demonstrated ART4215 to be well tolerated. A recommended Phase 2 dose has been established for ART4215 in combination with talazoparib, and a randomized expansion cohort has been initiated to evaluate the combination in patients with BRCA deficient breast cancer.

The study will enroll up to 206 patients and will be conducted at multiple oncology centers across the USA and Europe. The trial is led by principal investigators Erika P. Hamilton, M.D., Director of the Breast Cancer and Gynecologic Cancer Research Program, Sarah Cannon Research Institute at Tennessee Oncology, and Timothy Yap, M.B.B.S., Ph.D., Associate Professor of Investigational Cancer Therapeutics and Medical Director of the Institute for Applied Cancer Science at The University of Texas MD Anderson Cancer Center. Phase 1 safety and tolerability data is expected in the first half of 2023.

About ALPN-303

ALPN-303 is a dual B cell cytokine antagonist being developed for multiple autoimmune and/or inflammatory diseases. Engineered by directed evolution, ALPN-303 potently inhibits the pleiotropic B cell cytokines B cell activating factor/B lymphocyte stimulator (BAFF, BLyS) and a proliferation inducing ligand (APRIL), which play key roles in B cell development, differentiation, and survival, and together contribute to the pathogenesis of multiple autoimmune diseases like systemic lupus erythematosus (SLE) and many other autoantibody-related inflammatory diseases. By simultaneously blocking these two cytokines, ALPN-303 has the potential to improve outcomes in patients suffering from severe autoimmune and/or inflammatory diseases.

This new DEP program will generate and evaluate additional DEP Antibody Drug Conjugates (ADCs).

This new agreement follows an earlier DEP Antibody Drug Conjugate (ADC) agreement that Starpharma signed with MSD in February 2021 as well as an expanded DEP Research Agreement with another large US biopharmaceutical company in June 2022.

"We are very pleased to add this new DEP ADC program with MSD and to continue building on our partnership with them in such an innovative and valuable area. This new DEP program underlines the potential clinical and commercial value our DEP technology can deliver," said Dr Jackie Fairley, CEO of Starpharma.

"This is the second DEP partnering agreement that Starpharma has signed in the last two months, signifying increased momentum and interest in the DEP platform."

Antibody-drug conjugates (ADCs) have become an increasingly valuable class of therapeutic agents in oncology and hematology. The design of ADCs incorporates the specific cell targeting property of antibodies with the cell killing properties of chemically conjugated drugs, to provide a targeted therapeutic with minimal off target toxicities.

Starpharma’s DEP ADCs have the potential to overcome the limitation of relatively low drug loading that is a feature of first-generation ADCs. The DEP technology allows precise attachment of drug loaded dendrimer(s) to targeting molecules with a high load of covalently link drug (4, 8,16, 32 drug molecules per dendrimer) providing a selective, homogeneous ADC with a significantly higher drug-antibody ratio (DAR) as compared to currently available ADCs.

Starpharma has previously demonstrated the advantages of DEP in ADCs in multiple preclinical studies, including for DEP HER-2 ADC, which showed significant tumour regression and 100% survival, outperforming Herceptin & Kadcyla in a human ovarian cancer model. DEP ADCs are the subject of both internal and partnered DEP programs.

Starpharma has multiple DEP partnerships with leading, international companies, including AstraZeneca, MSD, and Chase Sun, and the company’s DEP technology has already yielded four clinical-stage oncology products.

A new animal study has found that PAT-DX1, in combination with radiation therapy, improves survival in an animal model of brain cancer.

The study, which was conducted in the laboratory of Professor Terrance Johns at the Telethon Kids Cancer Centre, showed that combining a therapeutic dose of radiation with PAT-DX1 resulted in significantly prolonged survival in mice, compared to radiation treatment alone.

Additionally, the data also showed that even at a lower dose, PAT-DX1 as a single agent showed significant activity, confirming previous studies in brain cancer models

These results provide strong support for the potential use of PAT-DX1 to improve outcomes for patients with high-grade glioma – an aggressive and clinically challenging form of brain cancer.

Professor Terrance Johns said:

"These impressive results offer the potential for future clinical strategies that allow the reduction of radiation doses and its associated side effects, particularly in children. We are excited to be working with Patrys as we work to optimize strategies for combining standard of care with PAT-DX1 therapies."
