Pegylated Liposomal Doxorubicin, Bortezomib, Dexamethasone and Lenalidomide for Relapsed/Refractory Multiple Myeloma

Phase 2

Completed

• Conditions: Multiple Myeloma
• Interventions: Drug: DVD-R

• Registration Number: NCT01160484
• Lead Sponsor: Oncotherapeutics

Brief Summary

This is a phase II, multicenter, open label, nonrandomized study to evaluate the efficacy and safety of lenalidomide at a dose of 10 mg/dose in combination with bortezomib at 1.0 mg/m2/dose, pegylated liposomal doxorubicin (PLD) at 4.0 mg/m2/dose, and intravenous (IV) dexamethasone at 40 mg/dose in adult patients with relapsed/refractory multiple myeloma (MM). The study consists of a screening period, followed by up to eight 28 day open label treatment cycles, a final assessment to occur 28 days after the end of the last treatment cycle, and a follow-up period.

Detailed Description

Studies have shown that combinations of PLD and bortezomib have striking synergy in preclinical studies and impressive response rates (73 \& 89%) in early clinical trials for MM patients with relapsed/refractory disease as well as first-line therapy. In addition, the efficacy of PLD with bortezomib in anthracycline-insensitive patients has been greater than single-agent bortezomib when comparing across studies. The immunomodulatory drugs, thalidomide and lenalidomide, target the tumor cell microenvironment, are antiangiogenic, have an immune activation effect and also exert a direct cytotoxic effect on myeloma cells. A phase 1 clinical study by our group also demonstrated that low dose PLD, administered at a more frequent dosing schedule, in combination with bortezomib, and dexamethasone (DVD regimen) is well tolerated and associated with high response rates and durable responses. In this phase II prospective trial, we will evaluate this regimen and show that this change enhances the DVD-R regimen's safety and efficacy for patients with relapsed/refractory MM.

   • Serum potassium within the normal range

9. Disease free of prior malignancies for 5 years with exception of currently treated basal cell, squamous cell carcinoma of the skin, or carcinoma "in situ" of the cervix or breast

10. Registered into the mandatory RevAssist® program, willing and able to comply with the requirements of RevAssist®.

11. Females of childbearing potential must have a negative serum or urine pregnancy test and must either commit to continued abstinence from heterosexual intercourse or begin TWO acceptable methods of birth control.

12. Able to take aspirin (81 or 325 mg) daily as prophylactic anticoagulation (patients intolerant to acetylsalicylic acid (ASA) may use warfarin or low molecular weight heparin)

Exclusion Criteria

1. Plasma cell dyscrasia with polyneuropathy, organomegaly, endocrinopathy, monoclonal protein and skin changes syndrome

2. Plasma cell leukemia

3. Grade 2 peripheral neuropathy within 14 days before enrollment

4. Impaired cardiac function or clinically significant cardiac diseases, including myocardial infarction within 6 months prior to enrollment, New York Heart Association (NYHA) Class II or greater heart failure, Uncontrolled angina, clinically significant pericardial disease, severe uncontrolled ventricular arrhythmias, echocardiogram or Multigated acquisition(MUGA) scan evidence of left ventricular ejection fraction (LVEF) below institutional normal within 28 days prior to enrollment, electrocardiographic (ECG) evidence of acute ischemia or active conduction system abnormalities.
