Inhibition of ATX is a novel treatment strategy for cancer that offers a three-pronged attack on the tumor through cancer cell inhibition, immune system stimulation and inhibition of fibrotic processes. ATX-mediated lysophosphatidic acid (LPA) signalling directly encourages tumor cell proliferation and inhibits anti-tumor immune responses via a direct effect on T cells. Further, it has a predominant role in fibrotic processes, including those important in cancer propagation, metastasis and resistance to therapy. Cancers surrounded by scar tissue (fibrotic tissue) and without markers visible to the immune system are tough to treat with existing therapies.

IOA-289 is a novel ATX inhibitor with a unique chemical structure, excellent potency and an attractive non-clinical safety profile. It has a unique binding mode that places it in an inhibitor class of its own. Avoidance of interaction with the catalytic site likely contributes to the improved safety profile of IOA-289 compared to other ATX inhibitors, avoiding toxicities seen with first-generation entities.

Michael Lahn, Chief Medical Officer of iOnctura, commented: "Despite the advances in the treatment of cancer in the last few decades, a large proportion of tumors are resistant to current treatments such as chemotherapy, immunotherapy and radiotherapy. Based on this translational research, we are excited to be investigating the safety and mode of action of IOA-289 in pancreatic cancer patients, where ATX signalling plays a central role."

In this translational research, IOA-289 demonstrates positive effects in highly fibrotic cancer models, preventing metastasis and tumor outgrowth. In iOnctura´s Phase Ib clinical study, IOA-289 is being combined with standard of care nab-paclitaxel and gemcitabine. While assessing the safety of an ATX inhibitor in cancer patients for the first time, a broad biomarker program will investigate the translation of the non-clinical observations to clinical application. As demonstrated in healthy volunteers in this research, single ascending doses of IOA-289 were safe, tolerable and blood exposure showed a reduction of the pharmacologic marker circulating LPA. Disclosure of results of the ongoing Phase 1b study will be released at a future medical meeting.

Under the agreement, National Cancer Center Hospital East (NCCHE) will recruit patients and conduct the clinical trial, Ono will provide nivolumab, and Personalis will perform MRD and biomarker testing. Biomarker research will be conducted throughout the study, including sample analysis from both tumor lesion tissue and plasma circulating tumor DNA (ctDNA). The Personalis NeXT Personal platform will be used to correlate MRD status with standard of care imaging and drug response data by monitoring variances in ctDNA. Tissue samples will be analyzed by the Personalis ImmunoID NeXT platform to capture tumor molecular profile and tumor microenvironment features to better understand immunotherapy responses.

"We deeply value the opportunity to work with NCCHE and Ono – respected oncology leaders worldwide – to demonstrate the clinical validity of our ultra-sensitive liquid biopsy MRD assay, NeXT Personal, in early-stage rectal cancer patients to better predict drug response and disease recurrence in subsequent interventional trials based on ctDNA status," said Richard Chen, MS, MD, Executive Vice President, R&D and Chief Medical Officer at Personalis. "We believe that data from this study will be another step towards supporting the use of our highly sensitive MRD assay in rectal cancer and other cancer types."

"In our VOLTAGE study, we will include patients with dMMR resectable rectal cancer, who are being treated with nivolumab. Using NeXT Personal, we would like to investigate if an MRD negative result can be the surrogate marker of clinical complete response," said Hideaki Bando, MD, Assistant Chief, Department of Gastroenterology at NCCHE and Principal Investigator and Research Secretariat of the VOLTAGE-2 study. "We also would like to explore the association between immune microenvironment and efficacy of nivolumab using ImmunoID NeXT. These comprehensive assays may enable the selection of cases with high efficacies and will promote the non-operative management in dMMR rectal cancer."

On May 16, 2023 RadioMedix and Orano Med, two clinical stage radiopharmaceutical companies, reported that the last patient has been dosed in the Phase II trial of the targeted alpha emitter therapy, 212Pb-DOTAMTATE (AlphaMedix) (Press release, RadioMedix, MAY 16, 2023, View Source [SID1234631798]). This trial is being conducted to evaluate the safety and effectiveness of AlphaMedix in peptide receptor radionuclide therapy (PRRT) of naive patients with somatostatin receptor-expressing neuroendocrine tumors (NET), regardless of the location of the primary tumor. Top-line data from the trial is expected in mid-2024. Remarkably, based on data already collected, the objective response rate (ORR) endpoint has already been achieved and is more than twice as high as the current standard of care.

"The completion of the Phase II trial enrolment is a significant milestone in the clinical development of our innovative targeted alpha-emitter radiotherapy, AlphaMedix, and brings us one step closer to having this drug available to patients," said Ebrahim Delpassand, MD, Chairman and Chief Executive Officer of RadioMedix. "Previous studies have shown targeted alpha therapy (TAT) with AlphaMedix is well-tolerated. The preliminary efficacy data seen to date are very promising, particularly achieving the planned ORR endpoint. As the trial progresses, we believe the ORR could improve further. We look forward to reporting data on the study in 2024, which we believe will show that AlphaMedix will provide substantial benefit over currently FDA approved therapies for patients with metastatic or inoperable SSTR-expressing NETs."

This Phase II trial is a multi-center, single arm, non-randomized, open-label basket trial. Forty-one patients with histologically confirmed NETs and positive somatostatin analogue imaging who have not received prior PRRT have been enrolled across four sites in the United States. Treatment consists of four cycles of AlphaMedix at 8-week intervals. The primary endpoint of the trial is safety and effectiveness of AlphaMedix. Efficacy endpoints include objective response rate (ORR) using RECIST v1.1 criteria, progression-free survival (PFS), and overall survival (OS). Additional information about the trial can be found on clinicaltrials.gov: NCT 05153772.

Julien Dodet, President, and Chief Executive Officer of Orano Med, noted: "Completing this Phase II trial enrolment on schedule is a great achievement everyone involved and confirms the strong interest of the medical community for targeted alphatherapies with lead-212. We are convinced that targeted alphatherapies, such as AlphaMedixTM, are the future of radiopharmaceutical therapies, providing an increased cytotoxic potential against cancer cells with limited toxicity to surrounding healthy cells. This reinforces Orano Med’s commitment to make innovative lead-212-based therapies available to the medical community and patients worldwide."

About Targeted Alpha Therapy

Targeted alpha therapy (TAT) relies on a simple concept: combining the ability of biological molecules to target cancer cells with the short-range cell-killing capabilities of alpha-emitting radioisotopes. Alpha decay consists of the emission of a helium nucleus (alpha particle) together with very high linear energy transfer and a range emission of only few cell layers, resulting in irreparable double strand DNA breaks in cells adjacent only to area of alpha emission. This approach results in an increased cytotoxic potential toward cancer cells while limiting toxicity to nearby healthy cells. As a result, alpha emitters are considered as the most powerful payloads to be found for targeted therapies.

About AlphaMedixTM

AlphaMedixTM is a radiolabeled SSTR-targeting therapeutic investigational drug for the treatment of NETs patients. The product consists of SSTR-targeting peptide complex radiolabeled with 212Pb that serves as an in vivo generator of alpha-emitting particles. 212Pb isotope is particularly suitable for SSTR therapy applications based upon its half-life, energy, and decay properties.

About neuroendocrine tumors

Neuroendocrine tumors (NETs) are a heterogeneous group of rare neoplasms that originate from neuroendocrine cells. These neoplasms occur mostly in the gastrointestinal tract and pancreas but can also occur in other tissues including the thymus, lung, and other uncommon sites such as ovaries, heart, and prostate. Most NETs strongly express somatostatin receptors (SSTRs). In the United States, around 12,000 patients are expected to be diagnosed with neuroendocrine tumors, with an average 5-year survival rate of 60% at a metastatic stage.
