The company's innovative stem cell-based platforms are designed to potentiate and deliver oncolytic viruses, unleashing their full therapeutic potential in the fight against cancer.
Business Overview and History
Calidi Biotherapeutics was founded in 2014 with the goal of harnessing the power of oncolytic viruses to create effective cancer treatments. The company's journey began by identifying the key challenges in existing oncolytic virus therapies, such as immune system inactivation and poor tumor targeting. Calidi's founders recognized the need for a novel approach that could address these limitations and unlock the full potential of this promising modality.
In its early years, Calidi focused on organizing and staffing its operations, developing its business plan, raising capital, and building its technology and intellectual property portfolio. The company dedicated significant efforts to identifying potential product candidates and conducting preclinical studies and manufacturing processes.
A major milestone in Calidi's history came in 2021 when the company secured important licensing agreements with Northwestern University and City of Hope. These agreements granted Calidi the rights to commercialize the CLD-101 NeuroNova Platform for treating newly diagnosed high-grade glioma, as well as patents covering cancer therapies using oncolytic adenoviruses loaded into allogeneic neural stem cells for recurrent high-grade glioma treatment. These acquisitions significantly bolstered Calidi's pipeline and technological capabilities.
Like many early-stage biotechnology companies, Calidi has faced financial challenges throughout its history. The company has incurred substantial operating losses since its inception due to the capital-intensive nature of drug development in the biotechnology industry. To fund its operations, Calidi has relied on continuous capital raising through private sales of securities, including transactions with related parties.
A transformative event in Calidi's history occurred in September 2023 when the company completed a business combination with First Light Acquisition Group, Inc. This merger resulted in Calidi becoming a publicly-traded company on the NYSE American exchange under the ticker symbol CLDI. While this transaction provided Calidi with additional capital to advance its pipeline, the company continues to operate with limited resources as it pursues the development of its novel cell-based immunotherapy platforms.
Over the years, Calidi has built a robust pipeline of product candidates, each targeting different cancer types and stages of progression. The company's lead programs, CLD-101 NeuroNova and CLD-201 SuperNova, have made significant strides in preclinical and clinical development, showcasing the potential of Calidi's unique stem cell-based platforms.
CLD-101 NeuroNova, the company's lead product candidate, is designed to treat newly diagnosed and recurrent high-grade glioma (HGG), an aggressive form of brain cancer with limited treatment options. The NeuroNova platform utilizes immortalized neural stem cells to deliver an engineered oncolytic adenovirus directly to the tumor site, enhancing its anti-tumor effects. A completed Phase 1 clinical trial for newly diagnosed HGG demonstrated the safety and feasibility of this approach, setting the stage for an upcoming Phase 1b/2 trial in collaboration with Northwestern University.
Calidi's CLD-201 SuperNova program, on the other hand, focuses on advanced solid tumors, including head and neck cancer, triple-negative breast cancer, and soft tissue sarcoma. The SuperNova platform employs allogeneic adipose-derived mesenchymal stem cells (AD-MSCs) to protect, potentiate, and deliver an oncolytic vaccinia virus directly to the tumor microenvironment. Preclinical studies have shown promising results, and Calidi is preparing to initiate a Phase 1 clinical trial for this program in the first half of 2025.
In addition to its lead programs, Calidi is also exploring the potential of its Adult Allogeneic Adipose (AAA) stem cell platform for a wide range of regenerative medical applications, including cosmetics, orthopedics, and autoimmune diseases. The company's subsidiary, Nova Cell, Inc., has been established to spearhead these innovative stem cell-based product development efforts.
