Condition(s) targeted: Multiple Myeloma and Plasma Cell Neoplasm

Intervention: fluphenazine hydrochloride (Drug)

Phase: Phase 1/Phase 2

Status: Completed

Sponsored by: Immune Control

Summary

RATIONALE: Drugs used in chemotherapy, such as fluphenazine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. PURPOSE: This phase I/II trial is studying the side effects and best dose of fluphenazine and to see how well it works in treating patients with refractory advanced multiple myeloma.

Clinical Details

Official title: A Phase I/IIa, Open-Label, Dose-Escalation Study to Determine the Safety, Tolerance, and Preliminary Activity of Intravenous High-Dose Fluphenazine HCI in Patients With Advanced Multiple Myeloma

Study design: Masking: Open Label, Primary Purpose: Treatment

Primary outcome:

Safety

Efficacy

Detailed description: OBJECTIVES:

- Determine the safety of high-dose fluphenazine hydrochloride in patients with

refractory advanced multiple myeloma.

- Determine the pharmacological properties of this drug.

- Determine the effectiveness of this drug in these patients.

OUTLINE: This is an open-label, dose-escalation study. Patients receive high-dose fluphenazine hydrochloride IV 3 times on day 1. Treatment repeats every 28 days for 3 courses in the absence of disease progression or unacceptable toxicity. Cohorts of patients receive escalating doses of fluphenazine hydrochloride until the maximum tolerated dose is determined. PROJECTED ACCRUAL: A total of 30 patients will be accrued for this study.
