Aktis Oncology is a biotechnology company dedicated to realizing the curative power of alpha radiopharmaceuticals for the mainstream of cancer care.

Alpha-9 Oncology is a clinical stage, radiopharmaceutical company developing differentiated and highly targeted radiopharmaceuticals with the potential to meaningfully improve the treatment of people living with cancer. Applying proprietary technologies and deep-foundational expertise, Alpha-9 is on the forefront of engineering bespoke radiopharmaceuticals that are optimized to selectively deliver radiation to tumor sites while minimizing off-target effects. Alpha-9 is advancing a robust pipeline of novel radiopharmaceuticals with a systematic approach to molecule design that offers broad potential for expansion into several validated oncology targets. Alpha-9 was founded by researchers from the University of British Columbia and BC Cancer, with the goal of improving the lives of patients affected by metastatic cancers.

ARTBIO is a clinical-stage radiopharmaceutical biotechnology company focused on developing a new class of alpha radioligand therapies (ART). Our unique patient-centric approach is underpinned by a deep understanding of cancer biology and the infrastructure needed to effectively design, manufacture, and distribute our therapies.

Convergent Therapeutics is a clinical-stage biotechnology company exploring the full potential of dual-targeted combination strategies to treat cancer. Convergent has developed a therapeutic platform that is capable of targeting validated and novel cancer antigens. Building on breakthrough research developed by Dr. Neil Bander at Weill Cornell Medicine, Convergent has demonstrated that dual targeting of surface cancer molecules like Prostate-Specific Membrane Antigen (PSMA) improves antitumor efficacy. By leveraging targeting agents with different bio-distributions, such as monoclonal antibodies and ligands, supra-additive therapeutic doses are delivered to tumor cells without additive toxicity to the patient.

Cynosure is a leader in the medical devices industry specializing in aesthetic medicine and cosmetic procedures.

Invicro is a company in the medical imaging and biotechnology industry that specializes in imaging services for pharmaceutical and life sciences companies.

Lantheus Holdings, Inc. (NASDAQ: LNTH) is the parent company of Lantheus Medical Imaging, Inc. (LMI), which is a global leader in the development, manufacture and commercialization of innovative diagnostic imaging agents and products. LMI provides a broad portfolio of products, which are primarily used for the diagnosis of cardiovascular diseases. LMI’s key products include the echocardiography contrast agent DEFINITY® Vial for (Perflutren Lipid Microsphere) Injectable Suspension; TechneLite® (Technetium Tc99m Generator), a technetium-based generator that provides the essential medical isotope used in nuclear medicine procedures; and Xenon (Xenon Xe 133 Gas), an inhaled radiopharmaceutical imaging agent used to evaluate pulmonary function and for imaging the lungs.

A discovery through early clinical phase pharmaceutical company, Ratio Therapeutics employs a suite of innovative technologies to develop best-in-class targeted radiotherapeutics for the treatment of cancer. Ratio Therapeutics’ Trillium™ targeting scaffold combines pharmacokinetic modulation with best-in-class chelation technology to create proprietary small molecule targeting agents to attack a broad array of cancer targets. Our compounds accommodate imaging and therapeutic radioisotopes, ie "theranostics". The tunable nature of our platform combined with small-scale imaging trials in patients results in accelerated, de-risked compound selection.

TransCode's lofty goal is delivering a cancer-free future for all cancer patients. Our core belief is that cancer can be overcome through the intelligent design and efficient delivery of targeted therapeutics. Our lead therapeutic candidate, TTX-MC138, targets microRNA-10b, or miRNA-10b, considered the master regulator of metastatic cell viability in a range of cancers, including breast, pancreatic, ovarian, colon cancer, glioblastomas, and several others. Our other preclinical programs include two solid tumor programs, TTX-siPDL1, an siRNA-based modulator of programmed death-ligand 1, or PD-L1, and TTX-siLIN28B, an siRNA-based inhibitor of RNA-binding protein LIN28B. TransCode also has three cancer agnostic programs, TTX-RIGA, an RNA- based agonist of the retinoic acid-inducible gene I, or RIG-I, targeting activation of innate immunity in the tumor microenvironment; TTX-CRISPR, a CRISPR/Cas9-based therapy platform for the repair or elimination of cancer-causing genes inside tumor cells; and TTX-mRNA, an mRNA-based platform for the development of cancer vaccines that activate cytotoxic immune responses against tumor cells. Until now, targeting biomarkers that are the primary drivers of cancer onset, progression and recurrence have been locked behind the challenge of delivery – cytosolic delivery to engage these known targets. TransCode believes it has overcome this barrier, opening the door to a broad array of cancer therapies -- a disease with the highest unmet need that affects everyone. It is through the design and optimization of this technology that TransCode has devised an elegant solution -- TTX -- a proprietary delivery platform for the transport of targeted therapeutics to cancer cells. With their world class team and know how, TransCode has a rapidly expanding platform of drug candidates designed to target a variety of tumor indications with the goal of long-term treatment survival.
