Further study details as provided by University of Rochester:

Primary Outcome Measures:
  • Percentage of Afebrile Neutropenic Subjects [ Time Frame: 5 days ]
    To determine whether the percentage of neutropenic subjects that become afebrile by five days after fever first develops.

Enrollment: 36
Study Start Date: April 2011
Study Completion Date: April 2013
Primary Completion Date: April 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Daptomycin
Daptomycin intravenous 8mg/kg once per day 5-10 days.
Drug: Daptomycin
Other Name: Cubicin
Drug: Daptomycin
8 mg/kg once daily
Other Name: Cubicin
Placebo Comparator: Saline Placebo
Saline solution
Other: Saline Placebo
50 ml normal saline once daily

Detailed Description:
To determine whether the percentage of neutropenic subjects that become afebrile by five days after fever first develops is higher when daptomycin compared to placebo is added at the same time as anti gram-negative therapy. The five day time point is selected because it is at this point where it is recommended to add antifungal therapy to the treatment regimen if the patient is still febrile.

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

Inclusion Criteria:

  1. Patients in the above categories who are currently undergoing chemotherapy.
  2. Patients at least 18 of age.
  3. Patient expected to reach an absolute granulocyte count of <100 cells/mm3
  4. Patients who have given written consent because of the above criteria must have at least one temperature of greater or equal to 38.3° or temperatures > 38o on at least two occasions before study drug is administered.

Exclusion Criteria:

  1. Patients with lymphoma or with solid tumor undergoing initial chemotherapy. Their neutropenia is of insufficient duration for adequate test of the value of an anti-gram positive antibiotic.
  2. Patients undergoing auto-transplantation, for the same reason as above.
  3. Patients with evidence of a clinical infection such as presence of a pulmonary infiltrate by x-ray or clinical evidence for the presence of cellulitis.
