"Study looking at experimental combination of drugs to treat multiple myeloma"
Age: 18 to 100 years old
Healthy Volunteers: No
Keywords: multiple myeloma, cancer, myeloma
Type: Drug study, Phase I/II
This study looks at the side effects and best dose of clarithromycin (antibiotic) when given together with ixazomib citrate (experimental medicine), pomalidomide (immunotherapy) and dexamethasone (steroid) and to see how well it works in treating patients with multiple myeloma that has not responded to previous treatment. Biological therapies, such as clarithromycin, pomalidomide, and dexamethasone, use substances made from living organisms that may stimulate the immune system in different ways and stop cancer cells from growing. Ixazomib citrate may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Ixazomib (otherwise referred to as MLN9708) is a experimental medicine that has not yet been approved by the Food and Drug Administration (FDA). Giving clarithromycin with ixazomib citrate, pomalidomide and dexamethasone may be a better treatment for patients with multiple myeloma. The combination of drugs used in this study is experimental.

  • Absolute neutrophil count (ANC) >= 1,000/mm^3 and

  • Platelet count >= 50,000/mm^3; note: platelet transfusions to help patients meet eligibility criteria are not allowed within 3 days before study enrollment

  • Are postmenopausal for at least 1 year before the screening visit, OR

  • Are surgically sterile, OR

  • If they are of childbearing potential, agree to practice two effective methods of contraception, at the same time, from the time of signing the informed consent form through 90 days after the last dose of study drug, OR

  • Agree to practice true abstinence when this is in line with the preferred and usual lifestyle of the subject (periodic abstinence [e.g., calendar, ovulation, symptothermal, post-ovulation methods] and withdrawal are not acceptable methods of contraception)

  • Male patients, even if surgically sterilized (i.e., status post-vasectomy), must agree to one of the following:

  • Agree to practice effective barrier contraception during the entire study treatment period and through 90 days after the last dose of study drug, OR

  • Agree to practice true abstinence when this is in line with the preferred and usual lifestyle of the subject; (periodic abstinence [e.g., calendar, ovulation, symptothermal, post-ovulation methods] and withdrawal are not acceptable methods of contraception)

Exclusion Criteria:

  • Female patients who are lactating or have a positive serum pregnancy test during the screening period

  • Treatment with clarithromycin, anti-myeloma therapy including investigational agents or plasmapheresis within 30 days prior to treatment in this study

  • Failure to have fully recovered (i.e., =< grade 1 toxicity or to patient's clinical baseline) from the reversible effects of prior chemotherapy

  • Major surgery within 14 days before enrollment

  • Radiotherapy within 14 days before enrollment

  • Central nervous system involvement

  • Infection requiring systemic antibiotic therapy or other serious infection within 14 days before study enrollment

  • Evidence of current uncontrolled cardiovascular conditions, including uncontrolled hypertension, uncontrolled cardiac arrhythmias, symptomatic congestive heart failure, unstable angina, or myocardial infarction within the past 6 months

  • Systemic treatment within 14 days before the first dose of study drugs, or concurrent use, with any of the following:
