About this study

Official title: 64007957MMY1001: A Phase 1/2, First-in-Human, Open-Label, Dose Escalation Study of Teclistamab, a Humanized BCMA x CD3 Bispecific Antibody, in Subjects With Relapsed or Refractory Multiple Myeloma

The purpose of this study is to identify the recommended Phase 2 dose(s) (RP2Ds) and schedule assessed to be safe for Teclistamab and to characterize the safety and tolerability of Teclistamab at the RP2Ds.

Read the detailed description

The study will be conducted in 2 parts, separately for IV and SC administration: dose escalation (Part 1) and dose expansion (Part 2). It will evaluate safety, tolerability, pharmacokinetics and preliminary antitumor activity of Teclistamab administered to adult participants with relapsed or refractory multiple myeloma. The overall safety of the study drug will be assessed by physical examinations, Eastern Cooperative Oncology Group performance status, laboratory tests, vital signs, electrocardiograms, adverse event monitoring, and concomitant medication usage. Disease evaluations will include peripheral blood and bone marrow assessments at screening (performed within 28 days) and to confirm stringent complete response (sCR), complete response (CR), or relapse from CR. The end of study (study completion) is defined as 2 years after the last participant in Part 3 has received his or her initial dose of teclistamab. Study record NCT04557098 is Phase 2 part of this study and study record NCT03145181 is Phase 1 part of this study.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Dose Limiting Toxicity (DLT)

    The Dose Limiting Toxicities (DLTs) are based on drug related adverse events and defined as any of the following events: hematological / non hematological toxicity of Grade 3 or higher.

    Measured: Up to Day 28

  2. Number of Participants With Adverse Events (AEs) as a Measure of Safety and Tolerability

    An AE is any untoward medical occurrence in a participant participating in a clinical study that does not necessarily have a causal relationship with the pharmaceutical/biological agent under study.

    Measured: Up to 7 years and 3 months

Secondary outcomes (4)

  1. Teclistamab Serum Concentrations

    Concentration assessment will be done to evaluate the effect of Teclistamab.

    Measured: Up to 8 weeks

  2. Number of Participants with Teclistamab Antibodies

    Antibodies to Teclistamab will be assessed to evaluate potential immunogenicity.

    Measured: Up to 8 weeks

  3. Preliminary Antitumor Activity of Teclistamab at the RP2D(s) in Part 2

    Preliminary antitumor activity of Teclistamab will be done using the International Myeloma Working Group (IMWG) response criteria.

    Measured: Up to End of Treatment (Approximately 91 days)

  4. Biomarker Assessment

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Teclistamab (IV) and Teclistamab(SC) in people with Hematological Malignancies, run by Janssen Research & Development, LLC at 13 sites in 5 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 5 inclusion and 5 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: under way, not looking for participants, as of the sponsor's last update on 3 Nov 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 13 sites in United States, Spain, France, Netherlands, Sweden. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

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?

Dose Limiting Toxicity (DLT) (time frame: Up to Day 28). 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 NCT03145181, which also lists 14 linked publications.

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 3 Nov 2026.
