About this study
Official title: A Multicenter, Single-Arm, Open-Label, Expanded Access Program for Lenalidomide With or Without Dexamethasone in Previously Treated Subjects With Multiple Myeloma
Subjects who qualify for participation will receive lenalidomide with or without dexamethasone in 4 week cycles until disease progression is documented or lenalidomide becomes commercially available for the indication of multiple myeloma.
Read the detailed description
This was a multicenter, non-randomized, open-label, uncontrolled, single-arm treatment study of lenalidomide as monotherapy or in combination with dexamethasone in subjects with previously treated relapsed or refractory multiple myeloma, with measurable myeloma paraprotein in serum and/or urine. Subjects who met all of the eligibility criteria were enrolled into the study. Screening procedures took place within 28 days of first dose. Subjects who qualified for participation received oral lenalidomide at a dose of 25 mg daily for 21 days every 28 days.
Subjects had the following options for dexamethasone treatment at the discretion of the treating physician:
Option A: No dexamethasone.
Option B: Oral pulse dexamethasone administered at a dose of 40 mg daily on Days 1-4, 9-12, and 17-20 for each 28-day cycle.
Option C: Oral pulse dexamethasone administered at a dose of 20 mg daily on Days 1-4, 9-12, and 17-20 for each 28-day cycle.
Option D: Oral dexamethasone administered at a dose of 40 mg weekly on Days 1, 8, 15, and 22 for each 28-day cycle for all cycles. Treatment was to be continued as tolerated until disease progression developed.
Doses of lenalidomide were allowed to be reduced first from 25 mg to 15 mg and then in 5-mg decrements due to lenalidomide toxicity. Subjects who could not tolerate a daily dose of 5 mg for 21 days every 28 days were discontinued from treatment. At the discretion of the investigator, doses of dexamethasone were modified due to dexamethasone toxicity. Dose reduction and discontinuation schemes for dexamethasone varied according to the treatment option administered.
Study visits occurred every 2 weeks for the first 3 cycles of therapy and then every 4 weeks after the third cycle until disease progression was documented, study drug was discontinued for another reason, or lenalidomide became commercially available for this indication.

What is being measured
The primary outcome is the main question the study is designed to answer.
Incidence of Adverse Events Summarized by System Organ Class, Preferred Term, Severity, Seriousness, and Relationship to Treatment.
Data from all subjects who received any study drug were included in the analysis. Adverse events were classified using the Medical Dictionary for Regulatory Activities (MedDRA) classification system. A subject having the same event more than once was counted only once. Adverse events were summarized by worst NCI (National Cancer Institute) CTCAE (Common Terminology Criteria for Adverse Events) VERSION 3.0 grade. Incidence was defined as the number of subjects who experienced an adverse event within their period of participation in this study.
Measured: Median time-on-study=18.3 weeks

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing lenalidomide and dexamethasone in people with Multiple Myeloma, run by Celgene Corporation at 69 sites in 2 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 8 inclusion and 15 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 16 Mar 2010. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 69 sites in United States, Canada. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 3 Mar 2010). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Incidence of Adverse Events Summarized by System Organ Class, Preferred Term, Severity, Seriousness, and Relationship to Treatment. (time frame: Median time-on-study=18.3 weeks). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00179647, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Mar 2010.
