Study on the Safety, Anti-tumor Activity and Pharmacology of IPH2101 Combined With Lenalidomide in Patients With Multiple Myeloma Experiencing a First or Second Relapse

• Status: Completed
• Trial end date: 2014-02-01
• Target enrollment: 0
• Participant gender: All

Summary

The primary objective of the clinical study is to evaluate, in patients who experience a first or second relapse of their multiple myeloma, the safety of escalating doses of IPH2101 combined with lenalidomide

• Phase: Phase 1
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: Innate Pharma
• Treatments: Antibodies, Monoclonal; Lenalidomide; Thalidomide

Criteria

Inclusion Criteria:

1. Signed informed consent obtained before any trial-related activities

2. Progressive disease or relapse of multiple myeloma (according to the IMWG definition) after one or two prior therapeutic treatments or regimens for multiple myeloma that achieved a response duration of at least 6 months

3. Prior therapeutic treatment regimens may have included Thalidomide and Lenalidomide. Regarding patients previously treated by Lenalidomide, only patients who achieved at least Partial Response duration of at least 6 months can be included. The patient must not have discontinued treatment due to Lenalidomide intolerance.

4. Measurable disease, as indicated by one or more of the following:

• Serum M-protein ≥ 0.5 g/dL If Serum Protein Electrophoresis is felt to be unreliable for routine M-protein measurement (particularly for patients with IgA MM), then quantitative immunoglobulin levels can be accepted).

• Urine Bence-Jones protein ≥ 200 mg/24 h

• Involved serum Free Light Chains (sFLC) level ≥ 10 mg/dl ( ≥ 100 mg/l) provided sFLC ratio is abnormal (<0.26 or >1.65)

5. ECOG performance status of 0, 1 or 2

6. Clinical laboratory values at screening

• Calculated creatinine clearance (according to MDRD) > 60 ml/min

• Platelet ≥ 75 x 109 /l for patients with < 50% BM plasma cells, and ≥ 30 x 109 /l for patients with > 50% BM plasma cells

• ANC > 1 x 109 /l

• Bilirubin levels < 1.5 ULN ; ALT and AST < 3 ULN (grade 1 NCI)

7. Females of childbearing potential (FCBP)† must have a negative serum or urine pregnancy test with a sensitivity of at least 50 mIU/mL within 10 - 14 days prior to and again within 24 hours of prescribing Lenalidomide (prescriptions must be filled within 7 days) and must either commit to continued abstinence from heterosexual intercourse or begin TWO acceptable methods of birth control, one highly effective method and one additional effective method AT THE SAME TIME, at least 28 days before she starts taking Lenalidomide. FCBP must also agree to ongoing pregnancy testing. Men must agree to use a latex condom during sexual contact with a FCBP even if they have had a successful vasectomy

8. All study participants must be registered into the mandatory RevAssist® program, and be willing and able to comply with the requirements of RevAssist®.

Exclusion Criteria:

1. Age < 18 years or > 80 years

2. Non secreting multiple myeloma or non measurable disease (< 0.5 g /dL M-Protein in serum or < 200 mg urinary M-protein / 24 h or <10 mg/dl involved sFLC)

3. Life-threatening conditions related or not to MM relapse

4. Pregnant or breast feeding females. (Lactating females must agree not to breast feed while taking Lenalidomide)

5. Known hypersensitivity to thalidomide or IMiD®.

6. Use of any investigational agent within the last month

7. Treatment by systemic corticosteroids (except inhaled corticosteroids) or chemotherapy (including consolidation and maintenance) within the last month (use of biphosphonates is permitted)

8. Radiotherapy within the last month

9. Primary or associated amyloidosis

10. Peripheral neuropathy of grade ≥ 3 according to the CTCAE of the NCI

11. Abnormal cardiac status with any of the following

• NYHA stage III or IV congestive heart failure

• myocardial infarction within the previous 6 months

• cardiac arrhythmia remaining symptomatic despite treatment

12. Current active infectious disease or positive serology for HIV, HCV or positive Hbs Antigen

13. History of or current auto-immune disease

14. History of other active malignancy within the past 5 years (apart from basal cell carcinoma of the skin, or in situ cervix carcinoma)

15. Serious concurrent uncontrolled medical disorder

16. History of allograft or solid organ transplantation

17. Any psychological, familial, sociological or geographical condition potentially hampering compliance with the study protocol and follow-up schedule

18. Inability to comply with an antithrombotic regimen
