A Phase 3 interventional study of Isatuximab and Isatuximab in Multiple Myeloma, sponsored by University of Heidelberg Medical Center. Completed at 91 sites in 2 countries. Open to participants aged 18 Years to 70 Years. Per ClinicalTrials.gov, last updated 2026-02-18.

The trial aims to demonstrate the non-inferiority of subcutaneous to intravenous isatuximab administration in transplant-eligible patients with newly diagnosed multiple myeloma.
Prospective, multicentre, randomised, parallel group, open, phase III clinical trial, for patients with confirmed diagnosis of untreated multiple myeloma requiring systemic therapy.
Investigational Medicinal Product: Isatuximab, subcutaneous administration via a wearable injector system.
Randomization: Patients are randomized in one of 2 study arms (A or B) before induction therapy. Patients randomized in arm A will receive 3 cycles of the monoclonal antibody isatuximab intravenously, combined with RVd regimen (Lenalidomide, Bortezomib, Dexamethasone). Each cycle will last for 42 days. Patients in arm B will receive 3 cycles RVd plus isatuximab subcutaneously. After induction therapy, patients will receive standard intensification (usually cyclophosphamide-based mobilization therapy, stem cell collection and high-dose melphalan followed by autologous stem cell transplantation (HDM/ASCT)). End of study will be after the first HDM/ASCT.
There is one primary objective:
Demonstration of non-inferiority of subcutaneous (SC) isatuximab compared to intravenous (IV) isatuximab, both in combination with RVd, with respect to rates of VGPR or better after induction therapy (according to standard International Myeloma Working Group (IMWG) response criteria).
Key secondary objectives are:
The duration of the trial for each patients is expected to be approximately 10 months (induction and intensification treatment).
3,760 studies on the registry are indexed under Multiple Myeloma; 769 are open to participants now.
This study's enrollment of 514 is above the median of 41 across 3,005 interventional studies indexed under Multiple Myeloma.

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.
Stem cell (bone marrow) transplants. Allogeneic uses cells from a donor; autologous uses your own cells, collected earlier and given back.
An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.
The New York Heart Association’s four classes of how much heart failure limits physical activity.
Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.
Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.
Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.
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 US National Cancer Institute’s scale of how severe an adverse event is — any unwanted medical event during a study, such as a symptom, an illness or an abnormal test result, whether or not a treatment caused it. Whether it did is judged separately.
“Side effects of earlier treatment resolved to grade 1 or less” means they have settled to mild or gone.
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.
Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.
The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).
The number of neutrophils, white blood cells that help fight infection, in a given amount of blood. Too few raises the risk of infection.
It is a count, not a percentage of the white cells. Limits are written in units that mean the same: ≥ 1.5 × 10⁹/L is ≥ 1,500 per mm³ (µL). Each lab has its own reference range.

Ran from Apr 2023 to primary completion in Jan 2026, 33 months.
Of 71 non-industry phase 3 interventional studies under Multiple Myeloma, half reached primary completion within 87 months of starting (the median), counting those still running; a quarter within 48 and three quarters within 108. This study's 33 months is below that.
Counting every sponsor, half of 178 studies reached it within 56 months; a quarter within 35 and three quarters within 95.
