Brief summary

Phase I study was to investigate the safety and tolerability of the photosensitizer (PS) 2-\[1-hexyloxyethyl\]-2-devinyl pyropheophorbide-a (HPPH) for injection in patients with Esophageal Cancer. It was to characterize the pharmacokinetics of HPPH and efficacy of HPPH.

Detailed description

The present study is phase I study to evaluate the safety, tolerability, and pharmacokinetics of multiple ascending injection doses of HPPH in Patients with Esophageal Cancer. Up to 30 patients are planned to be enrolled in 6 cohorts with each cohort consisting of 3-6 patients ( male and/or female patients). In each cohort, patients will receive HPPH and Lyophilized treatment. The dose escalation in Cohorts was from 2.5 to 3, 3.5, 4, 5, and 6mg/m2 of HPPH, respectively, administered intravenous drop infusion over 1 hour, once daily, and a fixed light dose of 150 J/cm delivered 48 hours after infusion of HPPH.

Interventions

DRUGHPPH 2.5 mg/m2

HPPH was administered as a single, 2.5 mg/m2, slow intravenous infusion over 1 hour , and a fixed light dose of 150 J/cm delivered 48 hours after infusion of HPPH.

DRUGHPPH 3 mg/m2

HPPH was administered as a single, 3 mg/m2, slow intravenous infusion over 1 hour, and a fixed light dose of 150 J/cm delivered 48 hours after infusion of HPPH.

DRUGHPPH 3.5 mg/m2

HPPH was administered as a single, 3.5 mg/m2, slow intravenous infusion over 1 hour, and a fixed light dose of 150 J/cm delivered 48 hours after infusion of HPPH.

DRUGHPPH 4 mg/m2

HPPH was administered as a single, 4 mg/m2, slow intravenous infusion over 1 hour, and a fixed light dose of 150 J/cm delivered 48 hours after infusion of HPPH.

DRUGHPPH 5 mg/m2

HPPH was administered as a single, 5 mg/m2, slow intravenous infusion over 1 hour, and a fixed light dose of 150 J/cm delivered 48 hours after infusion of HPPH.

DRUGHPPH 6 mg/m2

HPPH was administered as a single, 6 mg/m2, slow intravenous infusion over 1 hour, and a fixed light dose of 150 J/cm delivered 48 hours after infusion of HPPH.
