The quest for innovative treatments in oncology has led to significant advancements in various fields, including vascular-targeted photodynamic therapy (VTP). Among these developments, Padeliporfin VTP stands out as a promising approach for treating low-grade upper tract urothelial cancer (UTUC). This article delves into the current research on Padeliporfin trials, highlighting its potential, efficacy, and the ongoing Phase 3 ENLIGHTED study.

Understanding Padeliporfin VTP

Padeliporfin VTP is a novel oncology technology platform developed by ImPact Biotech, a clinical-stage biotechnology company. This treatment combines a photosensitizing drug, Padeliporfin, with a laser light delivery system to target and ablate solid tumors. The therapy involves intravenous administration of Padeliporfin, followed by activation with near-infrared light at 753 nm via an optic fiber, leading to local activation of Padeliporfin in the tumor microenvironment.

The ENLIGHTED Study

The Phase 3 ENLIGHTED study is a single-arm, non-randomized, open-label trial evaluating Padeliporfin VTP in patients with low-grade UTUC. The study aims to assess the efficacy and durability of Padeliporfin VTP in treating low-grade UTUC tumors in the kidney and ureter. It consists of two parts: an Induction Treatment Phase (ITP) and a Maintenance Treatment Phase (MTP).

  • Induction Treatment Phase (ITP): Patients receive 1 to 3 VTP treatments every 4 weeks until a complete response is achieved or treatment failure.
  • Maintenance Treatment Phase (MTP): Patients who achieve a complete response are followed with endoscopic evaluation every 3 months for up to 12 months.

Preliminary Results

Preliminary results from the ENLIGHTED study have shown encouraging response rates. As of the data cut-off, 12 patients had begun treatment, with 9 completing the ITP. Key findings include:

  • Complete Response Rate: 67% (6 out of 9) of the response-evaluable patients achieved a complete response at the end of ITP.
  • Safety and Tolerability: Padeliporfin VTP was generally well-tolerated, with most adverse events being Grade 1 or 2. Grade 3 events were observed in a few patients, but all events resolved within a short period.

Future Prospects

The ongoing ENLIGHTED study has reached the 50% patient enrollment threshold, with complete enrollment anticipated by the first quarter of 2025. Additional interim data from the trial is expected to be reported in Q4 of 2024. These developments underscore the potential of Padeliporfin VTP as a novel treatment for low-grade UTUC.

Conclusion

Padeliporfin VTP represents a significant advancement in the treatment of low-grade upper tract urothelial cancer. The preliminary results from the Phase 3 ENLIGHTED study demonstrate its efficacy and safety, positioning it as a potential best-in-class treatment.
