Brief summary
The primary purpose of the study is to evaluate the safety and efficacy and to generate PK and biomarker data for the combination of pomalidomide and low-dose dexamethasone in patients with refractory or relapsed and refractory multiple myeloma. The study consists of a Screening phase within 28 days prior to cycle 1 day 1, a Treatment phase and a Follow-up phase which starts within 28 days of discontinuation from study treatment, every 3 months for up to 5 years. In addition, the collection of steady-state PK data from a large population will enable robust population PK and assess Pomalidomide exposure response analyses. The exploratory objectives of the study are to investigate potential markers predictive of POM response or resistance and pharmacodynamic markers.
Interventions
Oral Pomalidomide at the starting dose of 4 mg on Days 1-21 of a 28-day cycle
Oral Low dose Dexamethasone at the starting dose of 40mg/day (≤ 75 years old) or 20 mg/day (\> 75 years old) on Days 1, 8, 15 and 22 of a 28-day cycle.

| Number of Participants With Treatment Emergent Adverse Events (TEAE) | From the first dose of study treatment up to 28 days following the last dose of study treatment. The median duration of treatment with pomalidomide and LD-dex was 21.4 weeks. | An adverse event (AE) is any noxious, unintended, or untoward medical occurrence that may appear or worsen in a subject during the course of a study. It may be a new intercurrent illness, a worsening concomitant illness, an injury, or any concomitant impairment of the subject's health, regardless of etiology. Any worsening (i.e., any significant adverse change in the frequency or intensity of a pre- existing condition) was considered an AE. The severity of AEs were graded based on the symptoms according to version 4.0 of the National Cancer Institute Common Terminology Criteria for Adverse Events. Second primary malignancies were monitored as events of interest and considered as part of the assessment of AEs.

Outcome results
Number of Participants With Treatment Emergent Adverse Events (TEAE)
An adverse event (AE) is any noxious, unintended, or untoward medical occurrence that may appear or worsen in a subject during the course of a study. It may be a new intercurrent illness, a worsening concomitant illness, an injury, or any concomitant impairment of the subject's health, regardless of etiology. Any worsening (i.e., any significant adverse change in the frequency or intensity of a pre- existing condition) was considered an AE. The severity of AEs were graded based on the symptoms according to version 4.0 of the National Cancer Institute Common Terminology Criteria for Adverse Events. Second primary malignancies were monitored as events of interest and considered as part of the assessment of AEs. A SAE = AE occurring at any dose that: * Results in death; * Is life-threatening * Requires inpatient hospitalization or prolongation of existing hospitalization * Results in persistent or significant disability/incapacity * Is a congenital anomaly/birth defect
Time frame: From the first dose of study treatment up to 28 days following the last dose of study treatment. The median duration of treatment with pomalidomide and LD-dex was 21.4 weeks.
Population: The safety population includes all enrolled participants who received at least one dose of the IP.

Cytogenetic Analysis
Cytogenetic analysis was to be performed using fluorescence in situ hybridization (FISH) methodology at a local laboratory, to evaluate the relationship between cytogenetic profiles and the combination of POM and LD-DEX in terms of response and outcome.
Time frame: Study entry
Population: Statistical analysis could not be performed due to high level of missing cytogenetic data as well as cytogenetic probe analysis being non- compliant with study requirements which lead to an inability to accurately identify specific cytogenetic abnormalities.
Kaplan Meier Estimate of Duration of Response
Duration of response, calculated for responders only, was defined as time from the initial documented response (SCR, CR, VGPR or PR) to the first confirmed disease progression, or death if no disease progression was recorded.
