InteRNA Technologies Announces U.S. FDA Clearance of IND Application for Phase I Clinical Trial with Lead microRNA Candidate INT-1B3 in Patients with Advanced Solid Tumors

On December 2, 2021 InteRNA Technologies, a clinical-stage biotech company developing microRNA (miRNA)-based therapeutics with a focus on cancer, reported it received Investigational New Drug (IND) clearance from the U.S. Food and Drug Administration (FDA) for the company’s Phase I clinical trial evaluating lead miRNA candidate, INT-1B3, in patients with advanced solid tumors (Press release, InteRNA Technologies, DEC 2, 2021, View Source [SID1234596412]). INT-1B3 is a lipid nanoparticle (LNP) formulated, chemically modified mimic of the endogenous tumor suppressor, miR-193a-3p, and represents a promising novel therapeutic approach that is designed to simultaneously address multiple hallmarks of cancer.

The IND approval enables InteRNA to expand the number of clinical sites and to facilitate the enrollment of patients for the dose expansion (Phase Ib) part of the trial in the United States. The first part of the Phase I trial was initiated in Europe at the beginning of 2021, with the dosing of the first patient in the dose escalation (Phase Ia) part in February. The treatment of the first patient in the Phase Ib cohort is planned for the second half of 2022.

"Receiving such a positive outcome from the FDA shortly after submitting a full IND application is a major achievement for us," commented Laurens van Pinxteren, Chief Operating Officer of InteRNA. "It underlines the high potential of our novel miRNA-based approach that enables us to address the multi-facetted disease cancer from different angles with one drug providing a novel therapeutic entity to patients with hard-to-treat solid tumors, such as advanced breast cancer or hepatocellular carcinoma."

Roel Schaapveld, CEO of InteRNA, added: "The IND approval enables us to enroll an international, diversified patient population, marking significant progress in the clinical evaluation of our novel therapeutic modality. The rapid, positive feedback by the FDA is highly encouraging and we look forward to start patient recruitment in the United States next year."

The multicentric, open-label, multiple ascending dose Phase I/Ib trial (NCT04675996) will investigate the safety, pharmacokinetics, pharmacodynamics and preliminary efficacy of INT-1B3 in patients with advanced solid tumors. The study is expected to enroll a total of up to 80 patients at up to 15 clinical centers in the United States and Europe. The Phase Ia part of the trial is currently ongoing in the Netherlands and Belgium and will enroll approximately 30 patients with advanced solid tumors. In the second part (Phase Ib) of the trial, approximately 50 patients with hepatocellular carcinoma or triple negative breast cancer will be enrolled in the United States and Europe. Topline results from the Phase Ia part of the study are expected in the first half of 2022.

About INT-1B3

INT-1B3’s unique mechanism of action addresses multiple hallmarks of cancer simultaneously. It directly targets tumor cells and the tumor microenvironment by specific modulation of multiple signaling pathway components across the PTEN tumor suppressor pathway and the oncogenic PI3K/Akt and Ras/MAPK pathways resulting in inhibition of proliferation and migration and induction of cell cycle arrest and apoptosis. The triggering of the immunogenic tumor cell death (ICD) process as well as downregulation of the adenosine-A2A receptor pathway through inhibition of CD39/CD73 leads to a decrease in immunosuppressive FoxP3/Lag3 regulatory T cells and monocytic myeloid-derived suppressor cells (mMDSCs), and maturation of dendritic cells. As a result, the immune system is activated, and long-term immunity is triggered by recruitment of CD8+ effector T cells leading to decreased metastasis development and improved animal survival compared to anti-PD1 treatment.

ITM and Navigo Proteins Announce Research Collaboration to Develop FAP-targeting Radionuclide Therapy to Address Solid Tumors

On December 2, 2021 ITM Isotope Technologies Munich SE, a leading radiopharmaceutical biotech company and Navigo Proteins GmbH, a premier protein engineering company developing optimized scaffold protein-based affinity ligands called Affilin molecules from its Precision Targeting toolbox, reported a research collaboration for the development of a fibroblast activation protein (FAP)-targeted radiopharmaceutical program for the treatment of solid tumors (Press release, ITM Isotopen Technologien Munchen, DEC 2, 2021, View Source [SID1234596411]). The program is planned to be added to ITM’s growing proprietary pipeline of Targeted Radionuclide Therapies spanning multiple radioisotopes and targeting molecules for optimal therapeutic effect. FAP-Targeted Radionuclide Therapy is a promising new approach to treating cancer within the precision oncology field.

Under the terms of the agreement, Navigo’s proprietary protein engineering platform will be used to develop and select a FAP-targeting Affilin molecule which will then be coupled with a therapeutic radioisotope provided by ITM. Following candidate selection, ITM will have the exclusive rights to further advance the radiolabeled FAP-specific Affilin through clinical testing in potentially multiple cancer indications. The agreement also includes a non-exclusive license for diagnostic use in radio-imaging. Further details of the agreement were not disclosed.

"FAP-targeting approaches have received heightened attention for good reason. We believe this approach holds the potential to treat a wide range of cancer indications. As such, we look forward to exploring this innovative targeted radiopharmaceutical approach for our growing precision oncology pipeline, further expanding its reach and breadth. We believe that developing a new candidate by combining our radioisotopes with an Affilin ligand targeting FAP has the opportunity to make a difference in the lives of patients," commented Steffen Schuster, CEO of ITM.

FAP is a highly attractive tumor target for Targeted Radionuclide Therapy that is preferentially expressed on cancer cells and in particular on cancer associated fibroblasts (CAFs). It is detectable in most epithelial cancers, including over 90% of breast, lung, colorectal and pancreatic carcinomas. High expression levels are associated with poor prognosis, and therefore warrant additional medical research and focus. ITM and Navigo are addressing this urgent need through their research collaboration and combined efforts to develop a promising FAP-targeted radiopharmaceutical.

"We welcome the opportunity to extend our productive partnership with ITM with yet another promising project. We strongly believe in the potential of our technology to generate high-quality Affilin ligands targeting FAP and capable of breaking the tumor microenvironment. By joining forces with ITM, we are fully equipped to build a strong FAP-targeting candidate, that ITM will then advance through clinical development," said Henning Afflerbach, CEO of Navigo Proteins.

The therapeutic candidate developed together by ITM and Navigo will enable a direct attack against tumor cells by irradiating them via crossfire effects in a highly precise manner. Through the direct depletion of CAFs it additionally provides a new access point to modify the tumor microenvironment in which CAFs play a central role in upholding the barrier for effective immune cell infiltration.

This agreement further strengthens the existing partnership between the two organizations, combining ITM’s deep expertise in developing promising Targeted Radionuclide Therapies for cancer patients with Navigo’s proprietary Affilin molecules and protein engineering proficiency.
