A Tasisulam and Midazolam Drug Interaction Study in Cancer Patients

This study has been terminated.
(Terminated based on safety results from another trial)
Information provided by:
Eli Lilly and Company Identifier:
First received: September 23, 2010
Last updated: April 12, 2011
Last verified: April 2011

The purpose of this study is to evaluate whether tasisulam acts as an inducer of CYP3A using midazolam as a sensitive and specific probe substrate of CYP3A.

The study will also assess the safety and tolerability of tasisulam and midazolam given in combination and document any antitumor activity with tasisulam.

Further study details as provided by Eli Lilly and Company:

Primary Outcome Measures:
  • Midazolam Pharmacokinetics, area under the concentration-time curve (AUC 0-tlast) [ Time Frame: 4 days ]
  • Midazolam Pharmacokinetics, concentration maximum (Cmax) [ Time Frame: 4 days ]
  • Midazolam Pharmacokinetics, area under the concentration-time curve (AUC 0-infinity) [ Time Frame: 4 days ]

Secondary Outcome Measures:
  • Number of participants with tumor response [ Time Frame: Baseline to study completion ]
  • Tasisulam pharmacokinetics, concentration maximum (Cmax) [ Time Frame: 15 days ]
  • Tasisulam pharmacokinetics AUC above the albumin corrected threshold [ Time Frame: 15 days ]

Enrollment: 10
Study Start Date: September 2010
Study Completion Date: January 2011
Primary Completion Date: January 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Drug Interaction arm Drug: Tasisulam
Patient specific dose, administered intravenously, on day 1 of a 28 day cycle. Minimum of one (1) 28 day cycle. Patients may continue to receive tasisulam until disease progression or until discontinuation criteria are met.
Other Name: LY573636
Drug: Midazolam
1.2mg, administered orally once prior to the initiation of tasisulam therapy and once on day 8 after initiation of tasisulam therapy


Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Have histologically or cytologically confirmed solid malignancy or lymphoma that is advanced and/or metastatic disease which has not responded to standard therapy or for which no standard therapy exists.
  • Have a performance status of less than or equal to 2 on the Eastern Cooperative Oncology Group (ECOG) scale
  • Have discontinued all previous therapies for cancer, including chemotherapy, radiotherapy, cancer-related hormonal therapy, or other investigational therapy for at least 30 days (45 days for mitomycin-C or nitrosoureas) prior to study enrollment and recovered from the acute effects of therapy. Limited field radiotherapy is permitted (in consultation with the investigator)
  • Have an estimated life expectancy, in the judgment of the investigator, of greater than or equal to 12 weeks

Exclusion Criteria:

  • Have received treatment within 30 days of the initial dose of study drug with an experimental agent for non-cancer indications that has not received regulatory approval for any indication
  • Have symptomatic central nervous system (CNS) malignancy or metastasis (screening not required). Patients with active brain metastasis are excluded
  • Have current acute or chronic leukemia
  • Patients who have clinically significant chronic obstructive pulmonary disease (COPD) or other respiratory diseases that may be at risk during periods of conscious sedation under midazolam
  • Patients with a known history of obstructive sleep apnea, difficult intubation, or syndromes associated with airway abnormalities.
