Brief Summary:

This research study is studying a combination of drugs as a possible treatment for multiple myeloma.

The drugs that will be administered are:

  • ABI-009 (nab-rapamycin)
  • Pomalidomide
  • Dexamethasone

Condition or disease Intervention/treatment Phase
Multiple Myeloma Drug: ABI-009 Drug: Pomalidomide Drug: Dexamethasone Phase 1

Detailed Description:

This research study is a Phase I clinical trial, which tests the safety of an investigational drug and also tries to define the appropriate dose of the investigational drug to use for further studies. "Investigational" means that the drug is being studied.

The FDA (the U.S. Food and Drug Administration) has not approved ABI-009 as a treatment for any disease.

The FDA has approved pomalidomide and dexamethasone as treatment options for multiple myeloma.

The purpose of this study is to determine whether ABI-009 (study drug) will be safe and slow the progress of the disease when used in combination with pomalidomide and dexamethasone, depending on what type of cancer.

ABI-009 is an inhibitor of an overactive biological pathway in the cancer cells. Pomalidomide is an immunomodulatory agent and believed to work by affecting the growth signals that keep cancer cells alive. Dexamethasone is a steroid which is believed to kill cancer cells. The investigators hope that the combination of ABI-009 with pomalidomide and dexamethasone will help stop the growth of the cancer.

  • Pomalidomide is given orally daily on days 1-21, 7 days off

  • Dexamethasone is given orally weekly on days 1, 8, 15, 22
Drug: ABI-009
ABI-009 is an mTOR inhibitor. This pathway is believed to be overactive in multiple myeloma.
Other Name: nab-rapamycin

Drug: Pomalidomide
Pomalidomide is an immunomodulatory agent and believed to work by affecting the growth signals that keep cancer cells alive.
Other Name: Pomalyst

Drug: Dexamethasone
Dexamethasone is a steroid which is believed to kill cancer cells
Other Name: Decadron

Primary Outcome Measures :
  1. Maximum tolerated dose. [ Time Frame: 1 Cycle (28-Days) ]
    The maximum Tolerated Dose (MTD) is the highest dose of ABI-009 (nab-rapamycin) when administered in combination with pomalidomide and dexamethasone that dose not cause unacceptable side effects. The maximum tolerated dose is determined in clinical trials by testing increasing doses on different groups of people until the highest dose with acceptable side effects is found. A standard 3+3 dose escalation design will be used to assess the MTD.

Secondary Outcome Measures :
  1. Overall response rate. [ Time Frame: 2 years ]
    The number of participants that achieve a partial response or better. This is assessed using International Myeloma Working Group criteria.

  2. Progression free survival. [ Time Frame: 2 years ]
    Progression free survival is defined as the time to disease progression or death from any cause, censored at date last known progression free for those who have not progressed or died. Progression is assessed using International Myeloma Working Group Criteria.

  3. Treatment-emergent adverse events. [ Time Frame: 2 years ]
    Adverse events will be assessed using CTCAE criteria.

  • Disease progression on or within 60 days of completion of last therapy.
  • All laboratory assessments should be performed within 21 days of initiation of protocol therapy unless otherwise specified.
  • Participant has given voluntary signed written informed consent before performance of any study-related procedure that is not part of normal medical care, with the understanding that consent may be withdrawn by the subject at any time without prejudice to their future medical care.
  • Eastern Cooperative Oncology Group (ECOG) performance status ≤ 2 (see Appendix A).
  • Age ≥ 18 years
  • Measurable disease of multiple myeloma as defined by at least one of the following:

    • Serum monoclonal protein ≥ 0.5 g/dL
    • ≥ 200 mg of monoclonal protein in the urine on 24-hour electrophoresis
    • Serum free light chain ≥ 100 mg/L (10 mg/dL) and abnormal serum free kappa to serum free kappa light chain ratio
