Clinical Trials

Iniparib (BSI-201) has been evaluated across multiple Phase 1, Phase 2, and Phase 3 clinical trials, focusing predominantly on solid malignancies such as metastatic breast cancer, ovarian cancer, glioblastoma, uterine carcinosarcoma, and advanced non-small cell lung cancer. Sponsored primarily by Sanofi alongside academic entities like the Institut du Cancer de Montpellier - Val d'Aurelle, these studies assessed iniparib as monotherapy or in combination with chemotherapeutics. Currently, these trials have attained completed, terminated, or no longer available recruitment statuses.

Compliance for Clinical Use

Mechanism and Biochemical Profile

Iniparib covalently binds to poly (ADP-ribose) polymerase-1 (PARP1), inhibiting its enzymatic activity and blocking the repair of single-strand DNA breaks. This accumulation of unrepaired genomic damage leads to double-strand DNA breaks and apoptotic cell death, restricting tumor cell proliferation in clinical indications such as breast cancer, ovarian cancer, and glioblastoma.

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).
