Clinical Trial Summary

This is a multicenter, randomized, blinded, 2-arm phase IIb trial that will compare the efficacy and safety of Lenalidomide maintenance after Bortezomib/Melphalan/Prednison (VMP) induction to VMP without maintenance (Placebo). In addition the trial will assess the treatment of Revlimid/low dose Dexamethasone (Rd) as Salvage after VMP without sufficient response (less than PR) in an observational arm. Key eligibility criteria include patients with newly diagnosed multiple myeloma and who are 65 years of age or older or are not candidates for high-dose chemotherapy and autologous stem cell transplantation. Patients with poor performance status or serious coexistent medical conditions will be excluded from this study. After registration all patients receive 6 cycles VMP (modified according to Mateos et al.). Patients who receive at least a PR and completed VMP can be randomized to either Lenalidomide 10 mg/d continuously maintenance or to placebo. Randomization will be stratified according to the quality of response after VMP induction (PR vs. VGPR + stringent complete remission [sCR] + CR). Patients that are not able to complete VMP due to toxicity but reached at least a PR after a minimum of four cycles of therapy should immediately proceed to randomization. Blinded phase continues until progression or end of study. After unblinding, patients who received placebo should be treated with Rd.

Patients that do not reach PR after induction with VMP or are progressive during treatment with VMP should not be randomized, but switched to the observation arm and treated with Rd immediately. The study treatment ends with the confirmed progression on maintenance treatment (Lenalidomide or placebo) for patients that reached PR with induction treatment, or with the confirmed progression on second-line therapy with Revlimid® and Dexamethasone for patients that did not reach PR on induction treatment. All patients will be followed up every 3 months after end of study treatment, until end of study. The study ends two years after Last Patient In (i.e. randomization for maintenance) if sufficient events for the primary endpoint were received, but not later than 8 years after trial initiation (whatever comes first).

Description:

Primary objective

• Estimate the gain in progression-free survival (PFS) by maintenance with Lenalidomide after induction with VMP in elderly patients or patients unfit for highdose chemotherapy in comparison with placebo after VMP

Secondary study objectives

• To compare response rates of VMP and Lenalidomide maintenance versus VMP and placebo

• To compare overall survival probabilities between patients treated with Lenalidomide maintenance and patients without maintenance treatment

• To compare the safety of VMP and Lenalidomide maintenance versus VMP and placebo

• To compare the QoL of VMP and Lenalidomide maintenance versus VMP and placebo

• To assess the safety and efficacy of Rd for poor responders on VMP

AND are at least 65 years of age or older or, if younger than 65 years of age, are not candidates for stem cell transplantation because:

• The patient declines to undergo stem cell transplantation

OR:

• Stem cell transplantation is not available to the patient

5. Eastern Cooperative Oncology Group (ECOG) performance status score of 0, 1, or 2

6. Female of childbearing potential (FCBP) † must:

• Understand the potential teratogenic risk to the unborn child

• Understand the need for effective contraception, without interruption, 4 weeks before starting study treatment, throughout the entire duration of study treatment, dose interruption and 28 days after the end of study treatment

• Be capable of complying with effective contraceptive measures and agree to use 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. FCBP 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)**

• Progesterone only hormonal contraceptive (birth control pills, injections, implants)*

• Tubal ligation

• Partner's vasectomy

• Additional effective methods:

• Male condom (partner)

• Diaphragm

• Cervical Cap

• (*)Because of the increased risk of venous thromboembolism in patients with multiple myeloma taking Lenalidomide and Dexamethasone, combined oral contraceptive pills are not recommended. If a patient is currently using combined oral contraception she should switch to one of the effective method listed above. The risk of venous thromboembolism continues for 4 to 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 systems 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.

• Be informed about and understand the potential consequences of pregnancy and the need to notify her study doctor immediately if there is a risk of pregnancy

• Agree to have two medically supervised pregnancy tests with a minimum sensitivity of 25 mIU/ml (milli-International Units per milliliter) prior to starting Lenalidomide. The first pregnancy test must be performed within 10 to 14 days prior to the start Lenalidomide and the second pregnancy test must be performed within 24 hours prior to the start of Lenalidomide. The patient will receive Lenalidomide only after the study doctor has verified that the results of these pregnancy tests are negative. She must understand the need to commence the study treatment as soon as study drug is dispensed following the second negative pregnancy test. This requirement also applies to FCBP who practice complete and continued abstinence.

• Must understand the need and accepts to undergo pregnancy testing in the frequency as follows: FCBP 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. This requirement also applies to FCBP who practice complete and continued abstinence.

• Females must agree to abstain from breastfeeding during study participation and for at least 28 days after study drug discontinuation.

A FCBP † is a sexually mature woman who has not undergone a hysterectomy or bilateral oophorectomy or who has not been naturally postmenopausal for at least 24 consecutive months (i.e., who has had menses at any time in the preceding 24 consecutive months).

Male subjects must:

• Understand the potential teratogenic risk if engaged in sexual activity with a pregnant female or a FCBP

• Understand the need for the use of a condom and agree to use condoms even if he has had a vasectomy, if engaged in sexual activity with a pregnant female or a female of childbearing potential , while taking study drug, during any dose interruptions and for 28 days after stopping study therapy.

• Agree to notify the investigator immediately, if pregnancy or a positive pregnancy test occurs in his partner during study participation.

• Agree to abstain from donating semen or sperm during therapy or for at least 28 days following discontinuation of study drug.
