New actinium-225 partnership with BWXT Medical, a global leader in medical isotope supply, supports growing pipeline opportunities
HAMILTON, ON and BOSTON, Jan. 6, 2023 /PRNewswire/ -- Fusion Pharmaceuticals Inc. (Nasdaq: FUSN), a clinical-stage oncology company focused on developing next-generation radiopharmaceuticals as precision medicines, today reported continued progress across its pipeline of target alpha therapies (TATs) and provided recent corporate highlights.
Fusion Chief Executive Officer John Valliant, Ph.D., commented, "With three Phase 1 clinical programs developing TATs as next-generation radiopharmaceuticals, Fusion is leading a wave of excitement in the radiopharmaceutical sector. Fusion is poised for an exciting year, with data from the Phase 1 study of FPI-1434 in solid tumors expressing IGF-1R expected in the second quarter. Additionally, we expect to file an investigational new drug application (IND) for FPI-2068, our first novel TAT being developed in collaboration with AstraZeneca, in the first quarter of 2023.
"While advancing our clinical programs, we've continued to focus on ensuring adequate actinium supply, and recently announced a new partnership with established global medical isotope supplier BWXT Medical. We are well positioned to execute on our clinical programs and continue to advance a diversified pipeline of cancer therapies generated through Fusion's internal R&D capabilities and technologies."
Portfolio Update
FPI-1434
In the Phase 1 study, Fusion is exploring various dose levels of FPI-1434 as well as two dosing regimens: one with FPI-1434 alone, and another in which a small dose of cold antibody (naked IGF-1R antibody without the isotope) is administered prior to each dose of FPI-1434. The Company anticipates reporting safety, pharmacokinetics, and imaging data, including any evidence of anti-tumor activity, from the Phase 1 study in the second quarter of 2023. Fusion continues to anticipate the initiation of a Phase 1 combination study with FPI-1434 and KEYTRUDA® (pembrolizumab) to occur six to nine months following determination of the recommended Phase 2 dose of FPI-1434 monotherapy.
FPI-1966
The Phase 1, non-randomized, open-label clinical trial of FPI-1966 in patients with solid tumors expressing FGFR3 is intended to investigate safety, tolerability and pharmacokinetics and to establish the recommended Phase 2 dose. Patient enrollment and dosing is ongoing. The first cohort of the Phase 1 portion of this study is designed to evaluate various doses of vofatamb ("cold antibody") to assess the impact of pre-dosing on tumor uptake and will inform the dosing regimen for the remainder of the study. The Company anticipates providing a clinical data update in 2024.
FPI-2068
Fusion and AstraZeneca are jointly developing FPI-2068, the first novel TAT created under the companies' multi-asset collaboration agreement. FPI-2068 utilizes Fusion's Fast-Clear™ linker technology to radiolabel an AstraZeneca bispecific antibody with actinium. The investigational new drug (IND) filing is expected to be submitted in the first quarter of 2023.
Fusion Pharmaceuticals is a clinical-stage oncology company focused on developing next-generation radiopharmaceuticals as precision medicines. Fusion connects alpha particle emitting isotopes to various targeting molecules to selectively deliver the alpha emitting payloads to tumors. Fusion's first program, FPI-1434 targeting insulin-like growth factor 1 receptor (IGF-1R), is currently in a Phase 1 clinical trial. The pipeline includes FPI-1966, targeting the fibroblast growth factor receptor 3 (FGFR3), currently in a Phase 1 study; and FPI-2059, a small molecule targeting neurotensin receptor 1 (NTSR1), which has received FDA investigational new drug (IND) clearance and will begin a Phase 1 study. In addition to a robust proprietary pipeline, Fusion has a collaboration with AstraZeneca to jointly develop novel targeted alpha therapies (TATs) and combination programs between Fusion's TATs and AstraZeneca's DNA Damage Response Inhibitors (DDRis) and immuno-oncology agents. Fusion has also entered into a collaboration with Merck to evaluate FPI-1434 in combination with Merck's KEYTRUDA® (pembrolizumab) in patients with solid tumors expressing IGF-1R. To support Fusion's growing pipeline of TATs, the company has signed strategic agreements for actinium supply with TRIUMF, Niowave, Inc. and BWXT Medical Ltd.
