Under the terms of the agreement, Caris and Elevation Oncology will jointly evaluate potential targets, some of which are not currently actionable by an existing therapeutic, identified on an ongoing basis by analyzing Caris’ Whole Transcriptome Sequencing (WTS) and Whole Exome Sequencing (WES) data. The companies can then elect to initiate a novel drug discovery program for those targets, or pursue licensing or product acquisitions, while retaining exclusive access to all targets selected by the parties.

"Caris is dedicated to advancing precision oncology for patients. We are thrilled to build upon our strategic relationship with Elevation Oncology and deepen the connection between molecular diagnostics and clinical development," said David Spetzler, M.S., Ph.D., MBA, President and Chief Scientific Officer of Caris Life Sciences. "By pairing our unique insight into potential genomic driver alterations gained through Caris’ market-leading molecular profiling capabilities with Elevation Oncology’s strength in executing innovative clinical oncology programs in genomically-defined populations, we aim to further close the gap between target identification and clinical investigation for potential new therapeutics."

"Through this collaboration between Elevation Oncology and Caris, we hope to demonstrate how biopharmaceutical and molecular medicine companies can work hand in hand to realize visions that are shared across the precision oncology community," said Shawn M. Leland, PharmD, RPh, Founder and Chief Executive Officer of Elevation Oncology. "At Elevation Oncology, we believe every cancer patient deserves the opportunity to be matched with an actionable, purposely selected therapeutic that is precisely targeted to their tumor’s unique genomic biomarkers. In Caris, we have found a collaborator who both shares this vision as a leader in genomic testing and who can provide real-world insights into emerging or underserved genomically-defined patient populations. Together, we believe we are pioneering a platform to accelerate the development of precision therapeutics and build toward a future where patients have the option of a matched therapy for every driver alteration – no matter how rare."

Caris Molecular Intelligence, the company’s proprietary, comprehensive tumor profiling approach assesses all 22,000 genes in both DNA and RNA, and proteins – unique to an individual’s cancer – to reveal a molecular blueprint in order to guide more precise and individualized treatment decisions. Caris’ CODEai is the most comprehensive data solution in the industry, with cancer treatment information and clinical outcomes data for over 244,000 patients covering over 1,000,000 data points per patient. The analysis of oncogenic fusions and mutations that are driver alterations for assessment under the collaboration will be conducted on both the historical dataset that has been compiled by Caris, and on an ongoing basis from the future tumor profiling data routinely generated from Caris’ platforms over the term of the agreement.

Therapeutics selected by the parties, and subsequent companion diagnostics, will be developed on a cost-sharing basis with revenue being shared on any approved therapeutics.

Safety Data Highlighting Low Rates of Adverse Events and Non-Relapse Transplant Related Mortality in Patients Receiving Iomab-B Presented at 2021 SNMMI Virtual Conference

On June 15, 2021 Actinium Pharmaceuticals reported safety data from its ongoing pivotal Phase 3 SIERRA trial of Iomab-B in patients with relapsed or refractory Acute Myeloid Leukemia (r/r AML) were presented at the 2021 Society of Nuclear Medicine and Molecular Imaging (SNMMI) Annual Meeting which was held virtually June 11th – 14th (Press release, Actinium Pharmaceuticals, JUN 15, 2021, View Source [SID1234584090]). The presentation highlighted Iomab-B’s targeting ability and corresponding safety data from 113 patients, representing 75% of patient enrollment on the SIERRA trial.
Iomab-B targets CD45, an antigen expressed on leukemia and lymphoma cancer cells and immune cells including bone marrow stem cells but not on cells outside of the blood forming or hematopoietic system. This allows high amounts of radiation to be delivered to the bone marrow via Iomab-B while sparing critical organs. As a result, statistically significant lower rates of sepsis were reported as well as lower rates of febrile neutropenia, mucositis and non-relapse transplant related mortality in patients receiving Iomab-B and bone marrow transplant (BMT) compared to patients that received salvage therapy and a BMT. In addition, patients who crossed over to receive Iomab-B and went to BMT after receiving salvage therapy but not achieving a complete response also had lower rates of sepsis, febrile neutropenia, mucositis and non-relapse transplant related mortality.
Dr. Mark Berger, Actinium’s Chief Medical Officer, commented, "Relapsed and refractory AML in older patients is a particularly challenging disease to treat. Patients are heavily pretreated making their disease resistant to most standard therapies and often have comorbidities that limit treatment options, particularly bone marrow transplant. It is highly encouraging to us that in the SIERRA trial thus far, Iomab-B has enabled all patients receiving a therapeutic dose to proceed to BMT, the only curative treatment option for this patient population. Importantly, Iomab-B has been well tolerated and we are elated with the safety data from 75% of patient enrollment in the SIERRA trial. Given the targeted nature of Iomab-B, we can spare non-targeted organs like GI tract and deliver higher amounts of radiation to the bone marrow, the target organ. We are thrilled to be able to highlight results of the SIERRA trial through 75% of patient enrollment at SNMMI and look forward to future opportunities to present topline data from the full study."

About Iomab-B
Iomab-B (I-131 apamistamab) is an Antibody Radiation Conjugate (ARC) that is intended to condition or prepare patients for a potentially curative bone marrow transplant (BMT) in a targeted manner with the goal of reducing adverse events and increasing patent access to BMT. Via the monoclonal antibody apamistamab, Iomab-B targets CD45, an antigen widely expressed on leukemia and lymphoma cancer cells, immune cells and stem cells. Apamistamab is linked to the radioisotope iodine-131 (I-131) and once its attached to its target cells, it emits energy that travels about 100 cell lengths, destroying a patient’s cancer cells and ablating their bone marrow. By carrying iodine-131 directly to the bone marrow in a targeted manner, Actinium believes Iomab-B can avoid the side effects of radiation on most healthy tissues while effectively killing the patient’s cancer and marrow cells.

Iomab-B is currently being studied in the pivotal Phase 3 SIERRA (Study of Iomab-B in Relapsed or Refractory AML) trial, a 150-patient, randomized controlled clinical trial in patients with relapsed or refractory Acute Myeloid Leukemia (AML) who are age 55 and above. The SIERRA trial is being conducted at preeminent transplant centers in the U.S. with the primary endpoint of durable Complete Remission (dCR) at six months and a secondary endpoint of overall survival. Upon approval, Iomab-B is intended to prepare and condition patients for a bone marrow transplant, also referred to as a hematopoietic stem cell transplant, in a potentially safer and more efficacious manner than the non-targeted intensive chemotherapy conditioning that is the current standard of care in bone marrow transplant conditioning. A bone marrow transplant is often considered the only potential cure for patients with certain blood-borne cancers and blood disorders.

Dr. Schultz presented on Saturday, June 12, 2021, as part of the Continued Education (CE) session titled, "Imaging of Therapeutic Radionuclides for Dosimetry." As part of the session, Dr. Schultz discussed the 203Pb/212Pb image-guided radionuclide therapy paradigm and key innovations that are advancing the approach. Key data presented substantiates the potential of 203Pb imaging as a surrogate for 212Pb therapeutics and the performance of Viewpoint’s chelation technology for delivering radiation specifically to tumors.

Viewpoint is currently advancing its new, proprietary class of personalized 212Pb-based alpha-particle radiopharmaceuticals to transform the treatment landscape of radiotherapies for cancer. Through its unique theranostic approach, the Company’s technology provides the ability to diagnose the tumor and then treat it. This two-step, personalized medicine process helps to identify patients that are more likely to respond to the Company’s therapy and potentially improve efficacy. At the same time, the use of imaging to personalize treatments has the potential to minimize potential toxicities associated with many other types of cancer treatments.

The Company’s image-guided targeted alpha therapies (TAT) leverage specialized targeting peptides to deliver the diagnostic 203Pb and cancer-killing 212Pb directly to the tumor. Targets are carefully selected to ensure they are overexpressed on cancer cells and minimally expressed on normal healthy cells. When the peptide is radiolabled with the Company’s diagnostic 203Pb, the patient can be imaged (i.e., SPECT/CT) to reveal cancer cells in the body. When the peptide is radiolabeled with 212Pb (alpha-particle emitting radiation) the target-peptide binding delivers powerful, yet locally deposited, cancer-killing alpha-particle radiation directly to cancer cells. This targeting mechanism allows for maximized therapeutic effects while minimizing off-target toxicities.

Oren Hershkovitz, PhD, CEO of Enlivex, stated, "We are pleased to have this patent granted in Europe, which adds to existing AllocetraTM patents in various countries around the world. Specifically, this new patent further strengthens our existing intellectual property portfolio covering the use of AllocetraTM for cancer therapy."

AllocetraTM is being developed as a universal, off-the-shelf cell therapy designed to reprogram macrophages into their homeostatic state. Diseases such as solid cancers, sepsis, COVID-19 and many others reprogram macrophages out of their homeostatic state. These non-homeostatic macrophages contribute significantly to the severity of the respective diseases. By restoring macrophage homeostasis, AllocetraTM has the potential to provide a novel immunotherapeutic mechanism of action for life-threatening clinical indications that are defined as "unmet medical needs", as a stand-alone therapy or in combination with leading therapeutic agents.
