Brief Summary

The purpose of this study is to evaluate the effects of the addition of daratumumab to pomalidomide and dexamethasone in terms of progression-free survival in subjects with relapsed or refractory Multiple Myeloma.

Detailed Description

This is a multicenter, Phase 3, randomized, open-label study comparing daratumumab, pomalidomide and low-dose dexamethasone (DaraPomDex) with pomalidomide and low-dose dexamethasone (PomDex) in subjects with relapsed or refractory Multiple Myeloma who have received at least 1 prior treatment regimen with both lenalidomide and a proteasome inhibitor and have demonstrated disease progression. Subjects will be randomized in a 1:1 ratio to receive either DaraPomDex or PomDex. The original design of this study was to treat subjects with daratumumab for intravenous (IV) infusion (Dara IV); however, as of Amendment 1, all new subjects will be dosed subcutaneously with daratumumab co-formulated with recombinant human hyaluronidase rHuPH20 (hereafter referred to as Dara SC). Subjects who already began treatment with Dara IV (ie, prior to Amendment 1) will have the option to switch to Dara SC on Day 1 of any cycle starting with Cycle 3 or later for the remainder of their participation in the study, and they will be counted toward the total of 302 subjects. Subjects will receive treatment until disease progression or unacceptable toxicity. Drug administration and follow-up visits will occur more frequently for early cycles (e.g., weekly or bi-weekly). Disease evaluations will occur every cycle and consist mainly of measurements of myeloma proteins. Subject safety will be assessed throughout the study. The primary endpoint will be progression-free survival (PFS). Study end is anticipated at approximately 5 years after the last subject is randomized.

2. Voluntary written informed consent before performance of any study-related procedure.

3. Subject must have measurable disease of MM as defined by the criteria below:

• IgG multiple myeloma: Serum M protein level ≥1.0 g/dL or urine M-protein level ≥200 mg/24 hours, or
• IgA, IgD, IgE, IgM multiple myeloma: Serum M-protein level ≥0.5 g/dL or urine M-protein level ≥200 mg/24 hours; or
• Light chain multiple myeloma, for subjects without measurable disease in the serum or urine: Serum immunoglobulin free light chain (FLC) ≥10 mg/dL and abnormal serum immunoglobulin kappa lambda FLC ratio.

4. Subjects must have received prior antimyeloma treatment. The prior treatment must have included both a PI- and lenalidomide-containing regimens. The subject must have had a response (ie, PR or better based on the investigator's determination of response as defined by the modified IMWG criteria) to prior therapy.

5. Subjects must have documented evidence of PD based on the investigator's determination of response as defined by the modified IMWG criteria on or after the last regimen.

6. Subjects who received only 1 line of prior treatment must have demonstrated PD on or within 60 days of completion of the lenalidomide containing regimen (ie, lenalidomide refractory).

7. Eastern Cooperative Oncology Group (ECOG) performance status score of ≤ 2.

8. Willingness and ability to participate in study procedures.

9. For subjects experiencing toxicities resulting from previous therapy, the toxicities must be resolved or stabilized to ≤Grade 1.

10. Any of the following laboratory test results during Screening:

1. Absolute neutrophil count ≥1.0 × 109/L;

2. Hemoglobin level ≥7.5 g/dL (≥4.65 mmol/L); (transfusions are not permitted to reach this level);

3. Platelet count ≥75 × 109/L in subjects in whom <50% of bone marrow nucleated cells are plasma cells and platelet count ≥50 x 109/L in subjects in whom ≥50% of bone marrow nucleated cells are plasma cells;

4. Alanine aminotransferase (ALT) level ≤2.5 times the upper limit of normal (ULN);

5. Aspartate aminotransferase (AST) level ≤2.5 x ULN;

6. Total bilirubin level ≤1.5 x ULN, (except for Gilbert Syndrome: direct bilirubin ≤1.5 × ULN);

7. Creatinine clearance ≥30 mL/min

8. Serum calcium corrected for albumin ≤14.0 mg/dL (≤3.5 mmol/L), or free ionized calcium ≤ 6.5 mg/dL (≤1.6 mmol/L).

11. Reproductive Status

1. Women of childbearing potential (WOCBP) must have 2 negative serum or urine pregnancy tests, one 10-14 days prior to start of study treatment and one 24 hours prior to the start of study treatment. Females are not of reproductive potential if they have been in natural menopause for at least 24 consecutive months, or have had a hysterectomy and/or bilateral oophorectomy.

2. Women must not be breastfeeding.

3. WOCBP must agree to follow instructions for methods of contraception for 4 weeks before the start of study treatment, for the duration of study treatment, and for 3 months after cessation of daratumumab or 4 weeks after cessation of pomalidomide, whichever is longer.

4. Males who are sexually active must always use a latex or synthetic condom during any sexual contact with females of reproductive potential, even if they have undergone a successful vasectomy. They must also agree to follow instructions for methods of contraception for 4 weeks before the start of study treatment, for the duration of study treatment, and for a total of 3 months post-treatment completion.

5. Male subjects must not donate sperm for up to 90 days post-treatment completion.

6. Female subject must not donate eggs for up to 90 days post-treatment completion.

7. Azoospermic males and WOCBP who are not heterosexually active are exempt from contraceptive requirements. However, WOCBP will still undergo pregnancy testing as described in this section.

Highly effective methods of contraception have a failure rate of < 1% when used consistently and correctly. Subjects must agree to the use of 2 methods of contraception, with 1 method being highly effective and the other method being additionally effective.

Because of the embryo-fetal risk of pomalidomide, all subjects must adhere to the pomalidomide pregnancy prevention program applicable in their region. Investigators should comply with the local label for pomalidomide for specific details of the program.

Exclusion Criteria

1. Previous therapy with any anti-CD38 monoclonal antibody.

2. Previous exposure to pomalidomide.

3. Subject has received antimyeloma treatment within 2 weeks or 5 pharmacokinetic half-lives of the treatment, whichever is longer, before the date of randomization. The only exception is emergency use of a short course of corticosteroids (equivalent of dexamethasone 40 mg/day for a maximum of 4 days) for palliative treatment before Cycle 1, Day 1 (C1D1).

4. Previous allogenic stem cell transplant; or autologous stem cell transplantation (ASCT) within 12 weeks before C1D1.

5. History of malignancy (other than MM) within 3 years before the date of randomization (exceptions are squamous and basal cell carcinomas of the skin, carcinoma in situ of the cervix or breast, or other non-invasive lesion that in the opinion of the investigator, with concurrence with the sponsor's medical monitor, is considered cured with minimal risk of recurrence within 3 years).

6. Clinical signs of meningeal involvement of MM.

7. Chronic obstructive pulmonary disease (COPD) with a Forced Expiratory Volume in 1 second (FEV1) <50% of predicted normal. Note that FEV1 testing is required for subjects suspected of having COPD and subjects must be excluded if FEV1 <50% of predicted normal.

3. Electrocardiogram showing a baseline QT interval as corrected QTc >470 msec.

9. Known active hepatitis A, B, or C.

10. Known HIV infection.

11. Gastrointestinal disease that may significantly alter the absorption of pomalidomide.

12. Subject has plasma cell leukemia (>2.0 × 109/L circulating plasma cells by standard differential) or Waldenström's macroglobulinemia or POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, monoclonal protein, and skin changes) or amyloidosis.

13. Any concurrent medical or psychiatric condition or disease (eg, active systemic infection, uncontrolled diabetes, acute diffuse infiltrative pulmonary disease) that is likely to interfere with the study procedures or results or that, in the opinion of the investigator, would constitute a hazard for participating in this study.
