Basic Information

• Recruitment Status: COMPLETED

Brief Summary

Imnovid in combination with dexamethasone is indicated in the treatment of adult patients with relapsed and refractory multiple myeloma who have received at least two prior treatment regimens, including both lenalidomide (Revlimid) and bortezomib (Velcade), and have demonstrated disease progression on the last therapy.

Patients with relapsed and refractory multiple myeloma who have received bortezomib, lenalidomide, dexamethasone combination, considered to be the multiple myeloma optimal treatment, can access to pomalidomide under marketing authorization only as from third line of treatment.

In France this combination is not authorized for marketing for a first line treatment and only patient randomized in the IFM/DFCI 2009 trial received it.

This study concerns patients previously randomized in the IFM/DFCI 2009 trial who have received bortezomib, lenalidomide and Dexamethasone combination in first line, which at progression/relapse time therapeutic opportunities remained limited and who cannot access pomalidomide under marketing authorization.

This study is a multicentre, phase 2, open label, study testing the triple combination of pomalidomide and cyclophosphamide and dexamethasone (PCD) in multiple myeloma patients who are refractory or in first progression/relapse after a first line treatment with bortezomib and lenalidomide, an IMiDs (an Immuno Modulatory Drug and a proteasome inhibitor) according to the IFM/DFCI 2009 trial.

In the IFM/DFCI trial, patients in arm A received eight cycles of the Velcade-Revlimid-Dexamethasone combination followed by 1 year of lenalidomide maintenance, patients in arm B received 3 cycles of Velcade-Revlimid-Dexamethasone combination plus melphalan 200mg/m2 with an autologous transplantation followed by 2 cycles of Velcade-Revlimid-Dexamethasone combination consolidation and 1 year of lenalidomide maintenance.

This study will contain 3 treatment phases:

• Study treatment phase:

All patients will receive 4 cycles (28 days) of pomalidomide-cyclophosphamide-dexamethasone combination.

• Consolidation phase (depends on the initial randomization in the IFM/DFCI 2009 trial):

• For patients previously randomized in IFM/DFCI 2009's arm A:

• Melphalan 200 mg/m2 followed by Autologous Transplantation
• Three months after, 2 cycles of pomalidomide-cyclophosphamide-dexamethasone combination
• For patients previously randomized in IFM/DFCI 2009's arm B:

• 5 cycles of pomalidomide-cyclophosphamide-dexamethasone combination
• Maintenance phase (identical to all patients) subsequent cycles of pomalidomide and Dexamethasone until progression / relapse or discontinuation for any other reason.

For arm B patients, in case relapse occurs at least 12 months after the end of the maintenance IFM/DFCI 2009 trial, they could proceed to a second autologous transplantation and therefore follow the arm A procedure. The decision to proceed to a second transplant will be made by the physician and the patient.

In order to have the same amount of patients enrolled in this trial in the initial Arm A and Arm B of the IFM/DFCI 2009 trial, once 50 patients have been included in either arm A or B, subsequent patients will be eligible if they have not been initially treated as the first 50 patients from either arm.

The primary endpoint is the response rate (Partial Response (PR) or better) after 4 cycles of the triple combination pomalidomide and cyclophosphamide and dexamethasone (PCD) in the studied population using International Myeloma Working Group (IMWG) response criteria.

9. Adequate bone marrow function, documented within 96 hours prior to treatment without transfusion or growth factor support, defined as:

• Absolute neutrophils ≥1000/mm3
• Platelets ≥75000/mm3
• Hemoglobin ≥8.5g/dl

10. Adequate organ function, documented within 96 hours prior to treatment, defined as:

• Serum creatinine clearance (Cockcroft-Gault formula) ≥50 ml/min
• Serum total bilirubin <2.0 mg/dl

11. Wash out period of at least 2 weeks from previous antitumor therapy or any investigational treatment.

12. Able to take antithrombotic medicines such as low molecular weight heparin or aspirin.

13. Subjects affiliated with an appropriate social security system

14. Agree to abstain from donating blood while taking study drug therapy and for at least 28 days following discontinuation of study drug therapy

15. Agree not to share study medication with another person and to return all unused study drug to the investigator

16. Female subjects of childbearing potential (*) must:

• Understand the potential teratogenic risk to the unborn child
• Understand the need and agree to use, and be able to comply with, two reliable forms of contraception simultaneously or to practice complete abstinence from heterosexual contact during the following time periods related to this study:

1. for at least 28 days before starting study drug;

2. while participating in the study;

3. dose interruptions; and

4. for at least 28 days after study treatment discontinuation.

The two methods of reliable contraception must include one highly effective method and one additional effective (barrier) method. Females of childbearing potential must be referred to a qualified provider of contraceptive methods if needed. The following are examples of highly effective and additional effective methods of contraception:

• Highly effective methods:

• Intrauterine device (IUD)
• Hormonal (birth control pills, injections, implants)
• Tubal ligation
• Partner's vasectomy
• Additional effective methods:

• Male condom
• Diaphragm
• Cervical Cap

Because of the increased risk of venous thromboembolism in patients with multiple myeloma taking pomalidomide and cyclophosphamide and dexamethasone, combined oral contraceptive pills are not recommended. If a female subject is currently using combined oral contraception the patient should switch to another one of the highly effective methods listed above. The risk of venous thromboembolism continues for 4-6 weeks after discontinuing combined oral contraception. The efficacy of contraceptive steroids may be reduced during co-treatment with dexamethasone.

Implants and levonorgestrel-releasing intrauterine devices are associated with an increased risk of infection at the time of insertion and irregular vaginal bleeding. Prophylactic antibiotics should be considered particularly in patients with neutropenia.

o Agree to have pregnancy testing based on the frequency outlined below.

Medically supervised pregnancy tests with a minimum sensitivity of 25 mIU/ml must be performed for females of childbearing potential, including females of childbearing potential who commit to complete abstinence:

• Before starting study drug: females of childbearing potential must have two negative pregnancy tests prior to starting study drug. The first pregnancy test must be performed within 10-14 days prior to the start of study drug and the second pregnancy test must be performed within 24 hours prior to the start of study drug. The patient may not receive study drug until the study doctor has verified that the results of these pregnancy tests are negative.
• During study participation and for 28 days following study drug discontinuation:

Females of childbearing potential with regular or no menstrual cycles must agree to have pregnancy tests weekly for the first 28 days of study participation and then every 28 days while on study, at study discontinuation, and at day 28 following study drug discontinuation.

If menstrual cycles are irregular, the pregnancy testing must occur weekly for the first 28 days and then every 14 days while on study, at study discontinuation, and at days 14 and 28 following study drug discontinuation.

*Criteria for women of childbearing potential: This protocol defines a female of childbearing potential as a sexually mature woman who: 1) has not undergone a hysterectomy or bilateral oophorectomy or 2) has not been naturally postmenopausal (amenorrhea following cancer therapy does not rule out childbearing potential) for at least 24 consecutive months (ie, has had menses at any time in the preceding 24 consecutive months).

17. Male subjects must:

• Practice complete abstinence or agree to use a condom during sexual contact with a pregnant female or a female of childbearing potential while participating in the study, during dose interruptions and for at least 28 days following study drug discontinuation, even if he has undergone a successful vasectomy.
• Agree not to donate semen or sperm during study drug therapy and for at least 28 days following discontinuation of study drug.

2. Primary amyloidosis or myeloma complicated by amyloidosis

3. Pregnant or breast feeding females

6. Patients with non-secretory MM

7. Prior history of malignancies within 10 years

8. Evidence of Central Nervous System (CNS) involvement
