Feasibility of Prophylactic Haldol to Prevent Delirium in Cancer Patients


This research study proposes to conduct an open label, feasibility study administering prophylactic oral haldol to patients undergoing a hematopoietic stem cell transplant (HSCT).

The study will address the following research aims: 1) To demonstrate the feasibility of enrolling HSCT patients in a prophylactic medication trial, 2) To determine the tolerability of oral haldol in HSCT patients and 2) To compare rates of delirium in HSCT patients who receive prophylactic haldol with an untreated historical control group.

Study Type

  • Study Type: Interventional
  • Study Design
    • Allocation: N/A
    • Intervention Model: Single Group Assignment
    • Primary Purpose: Supportive Care
    • Masking: None (Open Label)
  • Study Primary Completion Date: July 2013

Detailed Description

This is an open label, safety & feasibility, clinical drug trial. We will use historical controls from previous research with bone marrow transplant patients and delirium incidence at University of Iowa Hospitals and Clinics (UIHC) to evaluate the efficacy of prophylactic Haldol in the prevention of delirium. This study will recruit adult cancer patients undergoing hematopoietic stem cell transplant (HSCT) at UIHC.


  • Drug: Haldol

Arms, Groups and Cohorts

  • Experimental: Oral Haldol in patients undergoing HSCT
    • Prior to stem cell transplant participants will receive 5mg of liquid or pill form, oral Haldol. Every other day visits will take place following the first administration of the study drug until 14 days after the transplant.

Clinical Trial Outcome Measures

Primary Measures

  • Side Effects and Tolerability of Haldol in Patients With Undergoing Hematopoietic Stem Cell Transplant
    • Time Frame: Daily, up to 14 days following transplant
    • Categorize and quantify adverse events from start of drug (day 1) to end of study drug per (CTCAE) version 4.0
