Summary

This trial studies how rigosertib sodium, a drug taken orally or through IV, can help treat patients with a rare skin condition and advanced skin cancer who haven't responded to other treatments. The drug targets and kills cancer cells while leaving healthy cells alone. Rigosertib has shown potential as a therapeutic option for nonresectable cholangiocarcinoma, demonstrating antitumoral and radiosensitizing effects.

Who is the study for?
This trial is for adults aged 18-79 with Recessive Dystrophic Epidermolysis Bullosa (RDEB) who have Squamous Cell Carcinoma (SCC) that hasn't improved after standard treatments. Participants must not be on other cancer therapies, should understand the study and agree to participate, and need measurable SCC based on certain criteria. Pregnant women, those with active infections like HIV or hepatitis, uncontrolled health issues, or abnormal lab results can't join.
What is being tested?
The trial is testing how well rigosertib sodium works in treating patients with advanced skin cancer associated with RDEB. The goal is to see if rigosertib targets cancer cells without harming normal cells. Patients' quality of life will also be assessed during the study.
What are the potential side effects?
While specific side effects of rigosertib are not listed here, common side effects from similar medications may include nausea, fatigue, blood count changes leading to increased infection risk or bleeding problems. Allergic reactions to medication components could occur.

Trial Design

1Treatment groups
Experimental Treatment
Group I: Treatment (rigosertib sodium)Experimental Treatment2 Interventions
Patients receive rigosertib sodium either oral or IV over a 52 week period. Patients will take oral rigosertib continuously for a total of three weeks, every four-week cycle (three weeks on, one week off drug). For IV, rigosertib is administered as a 72-hr continuous infusion on Days 1, 2 and 3 of a 2-week cycle for the first eight 2-week cycles, then on Days 1, 2 and 3 of a 4-week cycle thereafter.

Other Research
The most common treatments for Dystrophic Epidermolysis Bullosa (DEB) include protein replacement therapy, gene therapy, and cell therapy. Protein replacement therapy involves delivering recombinant collagen type VII to skin wounds, which helps restore the structural integrity of the skin by replacing the defective or missing protein. Gene therapy, such as the use of viral vectors to deliver functional versions of the COL7A1 gene, aims to correct the genetic defect at the source, promoting the production of type VII collagen. Cell therapy, including the use of genetically modified autologous skin grafts, involves culturing a patient's keratinocytes with a corrected gene and applying them to affected areas to regenerate healthy skin. These treatments are crucial for DEB patients as they address the underlying genetic and protein deficiencies, potentially reducing blistering and improving skin stability.
