Study R8760-101 (NCT05999292) is evaluating the safety and dosimetry of 68Ga-R8760, a first-in-class small molecule radioligand imaging agent being developed for patients diagnosed with adrenocortical carcinoma. 68Ga-R8760 was discovered by Radionetics Oncology for identifying melanocortin 2 receptor (MC2R)-expressing adrenocortical cancer lesions to select patients who may benefit from MC2R-directed radioconjugate therapy. The multi-center study is being conducted in the United States in collaboration with global leaders in the treatment of adrenocortical carcinoma.

"Adrenocortical carcinoma is a disease with a desperate need for new agents, as the last drug approved by the FDA was in 1970. MC2R is highly expressed on adrenocortical carcinoma tumors with limited expression in healthy tissue outside of the adrenal gland itself. Theranostic targeting of MC2R may provide a new approach for identifying and treating adrenocortical carcinoma," said Dr. Gary Hammer, M.D., Ph.D., the Millie Schembechler Professor of Adrenal Cancer at the University of Michigan Rogel Cancer Center and scientific advisor to Radionetics Oncology.

"Starting this exciting clinical study is an important milestone and was achieved within two years of the founding of Radionetics Oncology," said Brett Ewald, Chief Operating Officer. "Our team has a deep understanding of G-protein coupled receptors (GPCRs), leading to the identification of novel and compelling first-in-class imaging and therapeutic targets for oncology, such as MC2R. This coupled with our company’s chemistry, biology, and clinical expertise allows us to rapidly develop potent and selective radiopharmaceutical agents for clinical evaluation." Radionetics Oncology is developing a pipeline of new radiopharmaceuticals against novel targets and plans to have three clinical programs by 2024.

About 68Ga-R8760

68Ga-R8760 is a gallium-68-labeled small molecule radioligand conjugate that selectively binds with high affinity to MC2R, a highly expressed target on adrenocortical carcinoma. It is the first imaging agent developed to localize and identify MC2R-expressing tumors and is being developed to identify patients with adrenocortical carcinoma who may benefit from a MC2R-directed therapeutic agent that is also being developed by Radionetics Oncology. Adrenocortical carcinoma is a rare cancer of the adrenal cortex with limited treatment options, especially in the recurrent or metastatic setting. Despite significant research efforts, the median survival of patients with metastatic disease is less than 15 months.

On October 30th, MAIA’s Chief Scientific Officer Sergei Gryaznov, Ph.D. will deliver a presentation detailing the latest findings from an investigational new drug-enabling study of MAIA’s second generation telomere-targeting agents derived from lipid-modified THIO molecules. The title of Dr. Gryaznov’s presentation will be "Telomerase-driven Telomeric DNA Modification as Potential Broad-spectrum Cancer Treatment Platform."

"The objective for our second-generation telomere-targeting molecule program is to discover new compounds with improved specificity towards cancer cells relative to normal cells and potentially increased anticancer activity, as well as better chemistry manufacturing control characteristics," said Vlad Vitoc, M.D., MAIA’s Chief Executive Officer. "Previous preclinical studies of several of our second-generation THIO-like agents have shown significantly higher efficacy than THIO. We look forward to presenting the latest findings at the end of this month."

THIO is currently in Phase 2 human clinical trials for non-small cell lung cancer treatment.

About THIO

THIO (6-thio-dG or 6-thio-2’-deoxyguanosine) is a first-in-class investigational telomere-targeting agent currently in clinical development to evaluate its activity in Non-Small Cell Lung Cancer (NSCLC). Telomeres, along with the enzyme telomerase, play a fundamental role in the survival of cancer cells and their resistance to current therapies. The modified nucleotide 6-thio-2’-deoxyguanosine (THIO) induces telomerase-dependent telomeric DNA modification, DNA damage responses, and selective cancer cell death. THIO-damaged telomeric fragments accumulate in cytosolic micronuclei and activates both innate (cGAS/STING) and adaptive (T-cell) immune responses. The sequential treatment with THIO followed by PD-(L)1 inhibitors resulted in profound and persistent tumor regression in advanced, in vivo cancer models by induction of cancer type–specific immune memory. THIO is presently developed as a second or later line of treatment for NSCLC for patients that have progressed beyond the standard-of-care regimen of existing checkpoint inhibitors.

The study, conducted using data from the PHELICAR clinical data registry (CDR), was led by Pr. Olivier Ludicarme, Head of Specialty, and Emergency Imaging Department at the Pitié-Salpêtrière AP-HP Hospital, Paris, France, and his team as well as teams from the Beaujon and Paul-Brousse AP-HP Hospitals. The primary focus of this study was on the evaluation of Median’s iBiopsy AI model for the detection of Hepatocellular carcinoma (HCC), ultimately targeting the early diagnosis of HCC.

HCC constitutes more than 90% of primary liver cancers, ranking as the third leading cause of death by cancer worldwide1. Notably, the 5-year survival rate of liver cancer patients is only between 3% to 13% if the cancer is diagnosed at advanced stage (C) yet rises significantly to 36% when diagnosed at early stage (A) and even higher when diagnosed at very early stage (0)2.

Results presented at the ESMO (Free ESMO Whitepaper) 2023 Congress under the abstract Computer-Aided HCC Lesion Detection Based on Deep Learning and CT Images (abstract 1209MO) describe the first development step of a model slated for integration into Median’s AI/ML tech-based end-to-end CADe/CADx3 Software as Medical Device (SaMD) for HCC early diagnosis, on multiphase CT images (Arterial and Portal phase). This initial work is centered on the detection features of Median’s future iBiopsy HCC CADe/CADx SaMD and is based on a cohort of 753 patients from AP-HP, suffering from chronic liver disease and HCC. For the study, data from 561 patients were used for the algorithm’s training & tuning, whereas data from 192 patients were used for its testing.

Median’s iBiopsy AI model, designed to detect HCC lesions as small as 10 mm in diameter, showcased promising results, achieving an impressive sensitivity rate of 92% on the test set. This notable achievement significantly surpasses the average sensitivity of 69%4 observed among radiologists without AI/ML tech-based computer aided detection. The next phase of research will focus on the small-size lesions to improve the diagnosis of very early stage (0) and early-stage (A) HCC.

Study results will be presented during the session Basic Science & Translational Research (ID 81), to be held on Sunday 22 October, session time: 8:30 – 10:05 am CEST, oral presentation time: 9:10 am CEST, Santander Auditorium – Hall 9.

As a reminder, PHELICAR is part of a large research collaboration agreement signed in March 2020 between AP-HP and Median Technologies, aiming at carrying out studies to be used for the development and validation of Median’s iBiopsy AI/ML tech-based algorithms. More specifically, PHELICAR is a large-scale clinical data registry (CDR) to accurately identify the specific tumor phenotypes to better diagnose and predict patient outcome in HCC and supports the ongoing rise of predictive and personalized medicine.

The Median iBiopsy team will attend the ESMO (Free ESMO Whitepaper) 2023 Congress and be at booth #522, Hall 5, from October 20 to 23 (exhibition dates) to discuss the study results as well as iBiopsy advancements.

About iBiopsy: iBiopsy is based on the most advanced technologies in Artificial Intelligence (AI) and Data Science (DS), benefiting from Median’s expertise in medical image processing. iBiopsy targets the development of AI/ML tech-based Software as Medical Devices (SaMD), to be used in several indications for which there are unmet needs regarding early diagnosis, prognosis and treatment selection in the context of precision medicine. iBiopsy currently focuses on Lung Cancer, Liver Cancer (HCC) and Liver Disease (NAFLD/NASH).
