Clinical Trials

A clinical trial evaluated saquinavir mesylate in combination with ritonavir for the management of human immunodeficiency virus infection. Sponsored by The HIV Netherlands Australia Thailand Research Collaboration, this combined Phase 2/Phase 3 study aimed to assess the pharmacokinetics and efficacy of the antiretroviral regimen. However, recruitment for the trial was recorded as withdrawn, leading to the discontinuation of the study prior to full execution.

NCT Number Recruitment Conditions Sponsor/Collaborators Start Date Phases

Compliance for Clinical Use

Mechanism and Biochemical Profile

Saquinavir mesylate selectively binds to the active site of HIV protease, inhibiting the enzymatic cleavage of viral Gag and Gag-Pol polyprotein precursors into mature, functional retroviral proteins. By halting retroviral particle maturation within infected host cells, this mechanism prevents the formation of infectious virions to control viral load in human immunodeficiency virus antiretroviral therapy.

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).
