IGM Biosciences Initiates First-in-Human Clinical Trial of IGM-7354 in Solid Tumors
The multicenter, open-label, dose escalation Phase 1 clinical trial will evaluate IGM-7354 intravenously administered as a monotherapy in patients with relapsed and/or refractory solid tumor cancers. The key objectives of this trial are to provide an initial assessment of pharmacokinetics, safety and immune cell proliferation. If IGM-7354 shows an encouraging safety profile and significant increases in T cells and natural killer (NK) cells in this clinical trial, the Company may begin combination studies of IGM-7354 with T cell engaging antibodies in 2024. The Company may also decide to pursue combination studies with CAR-T or CAR-NK cells with a partner.
“The initiation of this clinical trial is another significant milestone in IGM’s development, as it is the first clinical study of an IgM targeted immune cytokine,” said
IGM-7354 is a targeted IL-15/IL-15R IgM immune stimulating antibody for the treatment of patients with solid tumors and hematologic malignancies. The antibody binding domains of IGM-7354 target PD-L1 and are designed to concentrate the delivery of IL-15 in the area of cells with PD-L1 expression, including PD-L1-expressing tumors and tumor-draining lymph nodes. Through this targeting, IGM-7354 may be able to enhance the immune system’s activity in the tumor microenvironment, while potentially reducing systemic toxicities.
Cautionary Note Regarding Forward-Looking Statements
This press release contains forward-looking statements, including statements relating to IGM’s plans, expectations and forecasts and to future events. Such forward-looking statements include, but are not limited to: the potential of, and expectations regarding, IGM’s technology platform and its IgM antibodies and product candidates, including IGM-7354; and statements regarding the clinical development of IGM-7354, including plans for future combination studies involving IGM-7354. Such statements are subject to numerous important factors, risks and uncertainties that may cause actual events or results to differ materially, including but not limited to: potential delays and disruption resulting from the COVID-19 pandemic and governmental responses to the pandemic; IGM’s early stages of clinical drug development; risks related to the use of engineered IgM antibodies, which is a novel and unproven therapeutic approach; IGM’s ability to demonstrate the safety and efficacy of its product candidates; IGM’s ability to successfully and timely advance its product candidates through preclinical studies and clinical trials; IGM’s ability to enroll patients in its clinical trials; the potential for the results of clinical trials to differ from preclinical, preliminary, initial or expected results; the risk of significant adverse events, toxicities or other undesirable side effects; IGM’s ability to successfully manufacture and supply its product candidates for clinical trials; the potential impact of continuing or worsening supply chain constraints; the risk that all necessary regulatory approvals cannot be obtained; the potential market for IGM’s product candidates, and the progress and success of alternative therapeutics currently available or in development; IGM’s ability to obtain additional capital to finance its operations, if needed; IGM’s ability to obtain, maintain and protect its intellectual property rights; developments relating to IGM’s competitors and its industry, including competing product candidates and therapies; general economic and market conditions; and other risks and uncertainties, including those more fully described in IGM’s filings with the
