Rigosertib in Patients With Recessive Dystrophic Epidermolysis Bullosa Associated SCC

NCT04177498

Description:

This pilot trial studies how rigsertib sodium works in treating patients with Recessive Dystrophic Epidermolysis bullosa (RDEB) with locally advanced Squamous Cell Carcinoma (SCC). Rigosertib may selectively target Epidermolysis bullosa (EB) cancer cells while leaving normal EB cells unaffected.

Purpose

This pilot trial studies how rigsertib sodium works in treating patients with Recessive Dystrophic Epidermolysis bullosa (RDEB) with locally advanced Squamous Cell Carcinoma (SCC). Rigosertib may selectively target Epidermolysis bullosa (EB) cancer cells while leaving normal EB cells unaffected.

Detailed Description

      PRIMARY OBJECTIVES:

      I. To estimate the anti-tumor activity of oral or IV rigosertib in RDEB patients with
      advanced SCC that have failed prior standard of care, by determining the overall response
      rate (ORR) which is defined as the proportion of patients who achieve either a CR or a PR by
      RECIST v1.1 II. To evaluate the safety and tolerability of oral rigosertib administered
      either orally daily three weeks on, one week off or as 72h CIV infusions on day 1-3 of a two
      week-cycle for 8 cycles and then on day 1-3 of a 4 week cycle thereafter

      SECONDARY OBJECTIVES:

      I. Assess impact on quality of life (QoL) II. Biomarker analysis (to include markers of
      PI3K/Akt and PLK1 pathways) performed on all archival tissue from all patients

      EXPLORATORY OBJECTIVE:

      I. Exome sequencing of patient tumors before, during, and after treatment

      OUTLINE: Patients will receive rigosertib sodium as either oral capsules or IV infusion. Mode
      of application is determined by the responsible investigator depending on participant's
      needs, general condition, and possibility of ambulatory treatment or need of hospitalization.

      Patients will take oral rigosertib continuously for a total of three weeks of a four-week
      cycle (three weeks on, one week off drug).

      For IV treatment, patients will receive rigosertib IV 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.

      Patients will receive treatment over a 52 week period. After completion of study treatment,
      patients are followed periodically every 3 months over a 12 month period.
