Clinical Trials

Numerous clinical trials evaluate floxuridine (FUDR) across Phase 1, Phase 2, and Phase 3 studies, primarily targeting gastrointestinal malignancies such as unresectable colorectal liver metastases, gastric cancer, cholangiocarcinoma, and pancreatic adenocarcinoma. These protocols reflect completed, active, terminated, or withdrawn recruitment statuses and are sponsored by academic medical centers—including Memorial Sloan Kettering Cancer Center and City of Hope Medical Center—as well as pharmaceutical companies like Sanofi and Jazz Pharmaceuticals. Evaluated therapeutic approaches include hepatic arterial infusion regimens and liposomal combination formulations for advanced disease.

Check the Floxuridine (FUDR) product page for in-depth specifications, including solubility, stock solutions, MOA, and working concentrations.

Compliance for Clinical Use

Mechanism and Biochemical Profile

Floxuridine is an antimetabolite prodrug that, upon intracellular conversion, inhibits poly(ADP-ribose) polymerase and thymidylate synthase, thereby halting downstream nucleic acid synthesis and inducing severe DNA damage and apoptosis. This cellular cytotoxicity inhibits malignant cell proliferation, directly underpinning its clinical efficacy in regional chemotherapy for colorectal liver metastases and gastrointestinal carcinomas.

Appendix RUO and cGMP Quality Standards

Quality Dimension RUO (Research Use Only) cGMP (Current Good Manufacturing Practice)
Clinical Applicability Prohibited in human clinical trials or medical diagnostics. Mandatory for human clinical trials (Phase I–III) and therapies.
Regulatory Status Non-regulated grade; exempt from drug manufacturing laws. Legally enforced by health authorities (e.g., FDA, EMA, NMPA).
Facility Environment Unclassified analytical or research laboratories. Validated Cleanrooms (ISO Class 5–8) with continuous monitoring.
Quality Control Basic purity and activity testing. Rigorous safety release testing (Sterility, Endotoxin, Mycoplasma).
Process Validation Basic equipment calibration; no process validation required. Full qualification (IQ/OQ/PQ) and complete batch records.
Quality Assurance Vendor self-declared without required formal QMS. Mandatory QA/QC unit, Change Control, CAPA, and vendor audits.
Regulatory Impact High risk of IND rejection if used as a critical raw material. Required for IND/NDA filings, supported by Drug Master Files (DMF).

Footnotes

Regulatory Note: Governed by FDA (21 CFR Parts 210/211/312), EMA (EudraLex Vol 4), ICH Guidelines (E6/Q7/Q9/Q10), and compendial standards (USP <71>/<85>/<1043>).
