Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Although the introduction of novel agents to the autologous transplant procedure in patients less than 65 years old or to the Melphalan Prednisone regimen in elderly patients has significantly improved response rates and survival times, MM is a heterogeneous disease with divergent outcomes driven by the biologic characteristics, especially cytogenetic characteristics \[5, 6\]. Various studies have demonstrated that cytogenetic characteristic as detected by fluorescent in situ hybridization (FISH) was one of the most powerful prognostic marker in MM, especially presence of deletion of 17p13 (del17p) \[6, 7\] and translocation t(4;14) \[6, 7\] that represent approximately 20% to 25% of patients in the series \[8\]. The del(17p) and t(4;14) chromosomal abnormalities are associated with poor progression-free survival and shorter overall survival in newly diagnosed MM patients treated with traditional chemotherapy … The conclusion of recent studies were that a clear unmet medical need still exists for additional novel therapeutic options for the treatment of MM with del17p and t(4;14) and that novel agents should be proposed earlier in the patient evolution.
Pomalidomide belongs to the immunomodulators compounds which thalidomide is the parent compound and lenalidomide the most recently approved agent \[14\]. It is derived from thalidomide and shares a number of the beneficial pharmacologic properties with thalidomide. The efficacy of thalidomide has been limited by adverse effects, which include sedation, neuropathy, constipation, and deep vein thrombosis. This toxicity profile seems dose and duration-related,which have the potential of improved potency and reduced toxicity. By modifying the thalidomide structure through the addition of an amino group at the 4 position of the phthaloyl ring, pomalidomide was generated.
… A phase 2 randomised open label study of 2 modalities of Pomalidomide plus low-dose Dexamethasone in patients with Multiple Myeloma, refractory to both lenalidomide and bortezomib was conducted. This study was addressed to patients with MM who were symptomatic and progressive following at least two cycles of lenalidomide and two cycles of bortezomib (either separately or in combination). This study provides further evidence that pomalidomide has no-cross resistance with lenalidomide and suggests that it can provide benefit for patients who have relapsed after other novel therapies. This data demonstrated that pomalidomide has significant efficacy in MM and can be safely administered to myeloma patients.
STUDY RATIONALE. There is an increasing number of patients with adverse karyotypic abnormalities, such as del17p and t(4;14), that requires new therapeutic options to improve progression free survival and ultimately overall survival. Based on recent studies, we hypothesized that these patients might benefit from the combination of pomalidomide and dexamethasone. We have therefore designed a Multicenter Open label Phase II study of Pomalidomide and Dexamethasone in Progressive Relapsed or refractory Multiple Myeloma patients with deletion 17p or translocation (4;14) Adverse Karyotypic Abnormalities. This study will determine the efficacy and toxicity profile of pomalidomide and dexamethasone in patients with adverse prognostic factors as determined using adverse karyotypic abnormalities and that are in desperate need of novel therapeutics. This study will be conducted in accordance with "good clinical practice" and all applicable regulatory requirements, including, where applicable, the 2008 version of the Declaration of Helsinki.
STUDY INDICATION In relapsed and refractory MM patients, who are progressive, with MM characterized by Deletion 17p or translocation (4;14) Adverse Karyotypic Abnormalities STUDY DESIGN Overall design. This study is a Multicenter, Open-label, Single arm, Phase 2 study of pomalidomide and dexamethasone in relapsed or refractory MM patients with deletion 17p and translocation (4;14). Eligible patients must have a progressive, relapsed or refractory MM, a deletion 17p and/or translocation (4;14) using FISH technique and a measurable disease. There is no escalation dose study, the Maximum Tolerated Dose has already been determined in previous phase 1-2 escalation dose studies as 4 mg/day on day 1 to 21 of a 28 days cycle. The proposed dose of dexamethasone is considered standard. Patients will receive the pomalidomide and dexamethasone regimen until progression. This study will eventually improve time to disease progression and response rates, with no additional toxicity, as compared to other available regimens, in this subgroup of patients with myeloma characterized with an adverse prognosis.
Regimen Pomalidomide 4mg/day, oral route, from day 1 to 21 per 28 days cycle Dexamethasone 40mg weekly, oral route, on day 1, 8, 15, 22 per 28 days cycle for patients aged less than 75 years, and 20 mg once weekly oral route per 28 days cycle for patients aged 75 years and above.
Until progression either relapse or refractory.
Potentially eligible patients and informed of their rights and how to achieve the study will sign informed consent prior to undergoing any study-related procedures. Patients will undergo screening assessments for protocol eligibility within 28 days of randomization.
For all patients who enroll into this study, study visits and serial measurements of safety and efficacy will be performed on a monthly basis for the first 12 months then on a 2-months basis thereafter. Tumor response, including progressive Disease, will be assessed according to the IMWG criteria. The severity of Adverse Events will be graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events version 3.0. In this study, a central laboratory will analyze serum and urine protein electrophoresis tests (myeloma \[M\]-protein levels), serum and urine immunofixation studies (CHRU Lille). FISH cytogenetic will be performed in Nantes for all patients in the study.
Efficacy assessments will occur on a monthly basis (28 days, designated as Study Day) for the first 12 months then on a 2-months basis thereafter, regardless of current cycle day, and can be performed within 3 days to day one of the cycle. Study of vital signs and performance status is requested at Study Day.
Study Day 1 of Open-Label Treatment will occur on the day the patient starts the pomalidomide-dexamethasone regimen. This regimen is given on oral route for the 2 therapeutic agents tested. complete blood (cell) count will be monitored at least every 7 days (weekly) during the first cycle. It will also be monitored at the first day of each cycle thereafter.
Recommended concomitant therapy. All medications (prescription and non-prescription), treatments and therapies taken from 28 days prior to initiation of the study through the last dose of study drug, must be recorded in the case report form. Any treatments or therapies used to treat a Serious Adverse Event that occur within 28 days of discontinuation of study drug must also be documented.
In addition, all patients will be given prophylactic anti-thrombotic treatment, either aspirin daily (commercial supply) if the patient has no prior history of thrombosis events or low molecular weight heparin according to hospital guidelines or physician preference. All prophylactic antithrombotic treatment unless contraindicated according to hospital guidelines or physician preference must be recorded. All patients will be monitored for signs and symptoms of venous thromboembolism while on Pomalidomide.
The use of hematopoietic growth factors is permitted during the study. The use of bisphosphonates is permitted throughout the study at the discretion of the Investigator.
Other therapies considered necessary for the patient's well being may be administered at the discretion of the Investigator. These therapies may include antibiotics, analgesics, antihistamines, or other medications and transfusions of red blood cells, platelets, or fresh frozen plasma given to assist in the management of complications associated with multiple myeloma or its therapy.
Prohibited concomitant therapy Concomitant use of sargramostim, other anti-cancer therapies, including thalidomide, or other investigational agents is not permitted while subjects are receiving study drug of the study. The need for radiation therapy is considered to be a treatment failure. However, an exception (that is patients allowed to remain in the treatment phase of the study) is made for radiation therapy to a pathological fracture site to enhance bone healing or to treat post-fracture pain that is refractory to narcotic analgesics because pathologic bone fractures do not by themselves fulfill a criterion for disease progression End of study treatment. Patients may continue study treatment until Progression develops (last study drug intake of pomalidomide-dexamethasone regimen) at which time they will complete a Treatment Discontinuation visit as outlined in Table 2.
Follow-Up. Upon discontinuation from pomalidomide-dexamethasone study treatment for Progression or any other reason, patients will be assessed for 28 days. Serious Adverse Events will continue to be collected on patients during the first 28 days in Follow-Up. FCBP will have a final pregnancy test 28 days after the last dose of study drug if they have regular or no menstrual cycles; or 14 and 28 days after the last dose if menstrual cycles are irregular. In addition, patients who are discontinued from study treatment will be followed for overall survival and subsequent MM treatment regimens.
Patients who discontinue treatment for other reason than Progression will have response determined until Progression or until start of further myeloma therapy.
All patients will have survival data entered in the Case Report Form after progression, along with subsequent myeloma treatments.
Dose Interruption and Modification. Dose interruption and reduction for pomalidomide-dexamethasone regimen will be provided.
