Multiple early-stage clinical trials have evaluated abequolixron (RGX-104) in oncology, focusing on advanced solid malignancies such as recurrent or metastatic non-small cell lung cancer and endometrial cancer. A completed Phase 1 trial sponsored by Inspirna, Inc., assessed RGX-104 as both monotherapy and combination therapy. Additionally, a pilot study sponsored by the UNC Lineberger Comprehensive Cancer Center explored abequolixron combined with chemo-immunotherapy for non-small cell lung cancer, though this trial was ultimately terminated.

Mechanism and Biochemical Profile
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). |
