Clinical Trials

Multiple clinical trials sponsored by academic and medical institutions, including McMaster University, University of Haifa, Ben-Gurion University of the Negev, Clalit Health Services, and Carmel Medical Center, are evaluating interventions related to stroke, cerebrovascular disorders, and healthcare utilization. Operating under unassigned or non-applicable trial phases, these investigations focus on post-stroke recovery feasibility and sustainable healthcare resource management. Recruitment status across the protocols varies, with some currently recruiting participants and others not yet recruiting.

Compliance for Clinical Use

Mechanism and Biochemical Profile

SIS3 selectively inhibits Smad3 to block TGF-β1-dependent Smad3 phosphorylation and downstream transcriptional signaling, thereby reducing myofibroblast differentiation and type 1 procollagen expression. By suppressing TGF-β1/Smad3-driven fibrotic tissue remodeling, this mechanism provides potential therapeutic utility in mitigating vascular scarring and tissue damage associated with stroke and related cerebrovascular disorders.

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).
