About this study

Official title: A Phase 1/2, First-in-Human, Multicenter, Open-Label, Dose Escalation and Dose-Expansion Study of Single-Agent ISB 1442 in Participants With Relapsed/Refractory Multiple Myeloma

This study is a first-in-human, Phase 1/2, open label study that will evaluate safety and efficacy of ISB 1442 in relapsed/refractory multiple myeloma (R/R MM).

Read the detailed description

The study will be conducted in two phases:

  • Phase 1: Dose escalation in R/R MM
  • Phase 2: Dose expansions in select R/R MM

Participants will be treated at escalating dose levels in Phase 1 (dose-escalation phase) of the study. Once the safety of ISB 1442 is confirmed and a Recommended Phase 2 Dose (RP2D) is established in Phase 1 for a given indication, Phase 2 will be initiated for that indication.

Participants will receive ISB 1442, until disease progression, unacceptable toxicity, or any criterion for stopping the study drug or withdrawal from the trial occurs.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

    Participants will receive escalating SC doses of ISB 1442

    ISB 1442 SC injection dose regimen at RP2D until participants experience disease progression or unacceptable toxicity, or until any other discontinuation criterion is met

Study groups in NCT05427812
Study groupRoleWhat they receive
Phase 1: Dose escalationExperimentalParticipants with R/R multiple myeloma (MM) will be administered ISB 1442 weekly by subcutaneous (SC) injection in each 28-day cycle. Dose escalation will begin with an accelerated titration dose escalation and should certain conversion criteria be met, escalation will convert to the standard (3 + 3) dose escalation
Receives: Drug: ISB 1442 SC injection escalating doses
Phase 2 (Dose Expansion): R/R Multiple MyelomaExperimentalThis cohort includes the participants with pathologically confirmed R/R MM and must have received at least 3 prior lines of therapy, including proteasome inhibitors (PIs), immunomodulators (IMiDs), and anti CD38 therapies either in combination or as a single agent; and must not be candidates for regimens known to provide clinical benefit. Participants will receive the recommended Phase 2 Dose (RP2D) of ISB 1442 SC injection determined in Phase 1 of the study for treatment of R/R MM. Each treatment cycle duration is 28 days. The anticipated total duration for each participant will vary, depending on the number of cycles of treatment completed. The treatment phase will extend until participants experience disease progression or unacceptable toxicity, or until any other discontinuation criterion is met.
Receives: Drug: ISB 1442 SC injection at RP2D

Model description
Participants will be treated at escalating dose levels in Phase 1 (dose-escalation phase) of the study. Once the safety of ISB 1442 is confirmed and a recommended phase 2 Dose (RP2D) is established in Phase 1, Phase 2 will be initiated for that indication. The Phase 2 design uses the Simon two-stage design with stopping rules for lack of activity, as well as stopping rules for toxicity. Participants will receive ISB 1442, until disease progression, unacceptable toxicity, or any criterion for stopping the study drug or withdrawal from the trial occurs.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing ISB 1442 SC injection escalating doses and ISB 1442 SC injection at RP2D in people with Relapsed/Refractory Multiple Myeloma, run by Ichnos Sciences SA at 15 sites in 3 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 13 inclusion and 10 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: stopped early, as of the sponsor's last update on 17 Jan 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 15 sites in United States, Australia, India. 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 combined 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.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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

Are results available for this study?

The study was stopped early (reason given: Business decision). Results are not available in the source record.

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?

Phase 1: Frequency and Severity Of Treatment-Emergent Adverse Events (TEAEs) (time frame: Up to 18 months). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 17 Jan 2025.
