Etenta-Isa-VRd in Newly Diagnosed High-Risk Multiple Myeloma (CONQUISTADOR)

May 14, 2026 updated by: Universitätsklinikum Hamburg-Eppendorf

A Clinical Phase I/II, Multicenter, Open-label, National Study Evaluating Quintuplet Treat-ment With ISaTuximab, Bortezomib, Lenalidomide and Dexamethasone Plus Etentamig (Etenta-Isa-VRd) in Primary DiagnOsed High-Risk Multiple Myeloma Patients

This study is researching an experimental five-drug combination called etentamig, isatuximab, bortezomib, lenalidomide, and dexamethasone. The study is focused on participants with newly diagnosed multiple myeloma (NDMM) and high-risk disease who are eligible for autologous stem cell transplantation.

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Participants must have confirmed diagnosis of symptomatic MM per IMWG criteria.
  • Participants must have High-risk myeloma according to IMS/IMWG CGS
  • Participants must be considered a candidate for high-dose chemotherapy and ASCT, as described in the protocol.
  • Participants must have measurable disease as defined in the protocol. Eastern Cooperative Oncology Group (ECOG) performance status of 0-2 (WHO=3 is allowed only if caused by MM and not by co-morbid conditions).
  • Participants must have clinical laboratory values within a prespecified range.

Exclusion Criteria:

  • Known contraindications to the use of any IMP or axMP or required concomitant drugs or supportive treatment.
  • known systemic amyloidosis (except for AL amyloidosis of the skin or the bone marrow), POEMS syndrome, Waldenstrom's macroglobulinemia; primary plasma cell leukemia
  • Administration of systemic therapy for multiple myeloma except osteoprotective therapy. Emergency myeloma treatment with dexamethasone is allowed according to specifications in the protocol. It is allowed to include patients after 1 cycle of any anti-myeloma first-line treatment within the specifications of the protocol
  • known central nervous system involvement by MM.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Safety and tolerability (Phase I)
Time Frame: through induction treatment, on average 4 months
Number of dose-limiting toxicities (DLTs) in participants and rates of adverse events (AEs) of grade ≥2 and of severe AEs in participants
through induction treatment, on average 4 months
MRD negativity (Phase II)
Time Frame: through consolidation phase completion, an average of 1 year
MRD-negativity rate after 12 cycles (with a sensitivity of <10-5)

Secondary Outcome Measures

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Estimated)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
December 1, 2026

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
