A Phase 3 interventional study of Daratumumab and Lenalidomide in Multiple Myeloma, sponsored by Canadian Cancer Trials Group. Recruiting at 31 sites in Canada. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-10-14.
Sponsored by Canadian Cancer Trials Group · Phase 3, Interventional, and Treatment
Currently, daratumumab or isatuximab are given continuously (non-stop), along side lenalidomide, and dexamethasone as part of multiple myeloma treatment. are given continuously (non-stop). Recent observations suggest that stopping daratumumab or isatuximb after about a year and a half of treatment may work just as well as giving them continuously with lenalidomide and dexamethasone. Sometimes, bortezomib is also given. This study is being done to answer the question: is less daratumumab or isatuximab treatment as good as more?
The usual approach for people with myeloma who are not having a stem cell transplant is treatment with daratumumab or isatuximab in combination with lenalidomide, and dexamethasone. These drugs are given continuously until they are no longer effective or cause major side effects.
Those that decide to take part in this study, will be randomly placed in one of two groups. If in the usual care group, patients will continue all the myeloma medicines currently being taken. If in the experimental group, patients will stop the daratumumab or isatuximab injection, and continue taking the myeloma tablets currently being taken. Regardless of which group, patients will stay on treatment indefinitely as long they are benefiting from it.
3,760 studies on the registry are indexed under Multiple Myeloma; 769 are open to participants now.
This study's planned enrollment of 570 is above the median of 41 across 3,005 interventional studies indexed under Multiple Myeloma.

Exclusion Criteria:
Known (HIV) with \< 350 cells/microliter. Note that patients who are HIV positive are eligible, provided:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
The amount of disease can be tracked with a defined measurement, so the study can see whether it shrinks or grows. It might be a tumour measured on a scan or, in some blood cancers such as myeloma, a marker measured in blood or urine.
The criteria or the study team say which measurement counts — having no tumour visible on a scan does not by itself rule you out.
A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.
Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.
Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).
Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
The number of CD4 cells, a type of white blood cell, in a given amount of blood. It is used to follow how well the immune system is doing in HIV.
