A Phase 3 interventional study of Arm A: Belantamab Mafodotin and Arm B: Daratumumab Hyaluronidase in Multiple Myeloma, sponsored by PrECOG, LLC.. Recruiting at 1 site in United States. Open to participants aged 18 Years to 79 Years. Per ClinicalTrials.gov, last updated 2026-11-06.
Sponsored by PrECOG, LLC. · Phase 3, Interventional, and Treatment
Eligible participants with newly diagnosed myeloma who are not considered eligible or refuse bone marrow transplant will be enrolled. Participants will be randomized to either belantamab mafodotin or daratumumab given in combination with bortezomib, lenalidomide and dexamethasone. Treatment will continue until disease progression, unacceptable side effects or withdrawal of consent.
Belantamab mafodotin is a targeted cancer treatment that works against multiple myeloma cells. It combines a homing device (an antibody) with a powerful cell-killing drug (a toxin), delivering the toxin directly to cancer cells while largely sparing healthy cells.
Minimal residual disease (MRD) testing will be done on bone marrow samples obtained standardly during your treatment. MRD shows whether a very small number of cancer cells can still be detected after treatment, even if standard lab tests shows no signs of cancer.
The purpose of this study is to evaluate if belantamab mafodotin, bortezomib, lenalidomide and dexamethasone (BVRd) improves minimal residual disease (MRD) negative status and/or prolongs progression-free survival (PFS) compared with daratumumab, bortezomib, lenalidomide and dexamethasone (DVRd) in participants with newly diagnosed multiple myeloma.
This proposed Phase III multicenter, study is a randomized (1:1), open-label trial designed to show belantamab mafodotin in combination with bortezomib, lenalidomide and dexamethasone (VRd) will lead to higher minimal residual disease (MRD) negativity rate compared with daratumumab in combination with VRd newly diagnosed multiple myeloma (TI-NDMM). Patients must be ineligible for autologous stem cell transplantation because of their age (≥ 70 years) or aged 18 - 70 years with the presence of underlying medical conditions likely to have a negative impact on tolerability of high-dose chemotherapy with stem-cell transplantation, making them transplant ineligible OR transplant-eligible and refusing stem-cell transplantation until first relapse or later. In addition, progression-free survival (PFS) will also be longer.
After enrolling approximately 320 standard-risk patients (anticipated at approximately 400 total patients), the study will limit accrual to patients with high risk NDMM to allow for enrichment of this subgroup of patients.
Belantamab mafodotin is a monoclonal antibody that targets B-cell maturation antigen (BCMA), a protein expressed on the surface of plasma cells, and releases a cytotoxic agent called Monomethyl auristatin F, which destroys the plasma cells.
International Myeloma Working Group (IMWG) criteria will be used for disease response.
MRD samples will be obtained on standard of care bone marrow procedures. MRD testing will be performed on samples at time of screening, suspected complete response (sCR), after confirmed CR at applicable time points from Cycle1, Day 1 at 6, 12, 18 (optional), 24, 30 (optional) and 36 months then annually until progression. MRD testing will not be performed in real-time for this study. Bone marrow samples will also be obtained for future research at screening and time of progression.
Research peripheral blood samples will be obtained to measure levels of belantamab mafodotin in the blood, immune responses or antibodies to belantamab mafodotin for patients receiving belantamab mafodotin. In addition, research blood samples will be obtained on all patients to measure soluble B-cell maturation antigen (sBCMA) to help diagnose, monitor treatment effectiveness, and predict the prognosis of multiple myeloma.
Patient-reported outcomes will also be performed.

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.
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.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.
Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.
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.
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.
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.
How quickly the kidneys clear creatinine, a waste product, from the blood. A study may estimate it from a blood test with age, weight and sex (often by the Cockcroft–Gault formula), or measure it using blood and urine collected over a set time. Given in mL/min; higher is better.
Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.
Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.
The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.
“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.
A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.
Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.
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.
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.
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.
Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.
After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.
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.
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.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.
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.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.
The other ingredients in a medicine besides the active drug, such as fillers, colours or preservatives.
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.
