  • Note 1: an FCBP is a female who: 1) has achieved menarche at some time point, 2) has not undergone a hysterectomy or bilateral oophorectomy or 3) has not been naturally postmenopausal (amenorrhea following cancer therapy does not rule out childbearing potential) for at least 24 consecutive months (i.e., has had menses at any time in the preceding 24 consecutive months).
  • Note 2: True abstinence is acceptable when this is in line with the preferred and usual lifestyle of the patient. Periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception.

About this study

This is an investigator-initiated (IIS), phase 2, prospective, open-label, multinational study, designed to be conducted in approximately 14 sites. Eligible patients will initially receive six 28-day cycles of isatuximab, pomalidomide, and low-dose dexamethasone.

Following this phase:

Patients who achieve ≥VGPR will be randomized in a 1:1 ratio to receive isatuximab, given either Q2W or once monthly, plus pomalidomide and low-dose dexamethasone.

Patients with <VGPR will continue treatment with isatuximab Q2W, pomalidomide, and low-dose dexamethasone.

The study will last for 42 months (recruitment and follow-up period), starting from the date of the first patient in (FPI) to the date of the last patient last visit (LPLV).

Core study procedures consist of baseline and post-baseline safety and disease evaluations, including physical examination, hematologic/clinical chemistry tests, radiologic assessments, bone marrow evaluations, and blood/urine M-protein assessments.

Patients will be allowed to continue treatment until disease progression, death, unacceptable AEs, lost to follow-up, or consent withdrawal.

What is being measured

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

  1. Overall Response Rate (ORR)

    The primary endpoint is the ORR after six months of treatment with isatuximab in combination with pomalidomide, and low-dose dexamethasone. ORR is defined as the proportion of patients with stringent complete response (sCR), complete response (CR), VGPR, and partial response (PR), as assessed by the Investigator using the IMWG response criteria.

    Measured: After six months of treatment with isatuximab plus pomalidomide and low-dose dexamethasone

Secondary outcomes (6)

  1. Progression-free Survival

    Defined as the time from study treatment initiation (Cycle 1 Day 1) to the date of first documentation of progressive disease (PD), as assessed by the Investigator using the IMWG response criteria, or the date of death from any cause, or the initiation of further anti-myeloma treatment, or data cut-off, whichever occurs first.

    Measured: From study treatment initiation to progressive disease (PD), or initiation of further anti-myeloma treatment, or death, whichever occurs first. Maximum time period 42 months.

  2. Overall Survival (OS)

    Defined as the time from study treatment initiation (Cycle 1 Day 1) to the date of death from any cause. OS will be assessed throughout the treatment period and post EOT during long term follow-up until the end of the study.

    Measured: From study treatment initiation to death. Maximum time period 42 months.

  3. Minimal Residual Response (MRD)

    Defined as the proportion of patients achieving MRD-negative status, assessed at CR.

    Measured: Through study completion. Maximum time 42 months.

  4. Time to Response (TTR)

    Defined as the time from study treatment initiation (Cycle 1, Day 1) to the date of the first objective response of PR or better.

    Measured: From study treatment initiation to partial response (PR), or better. Maximum time period 42 months.

  5. Duration of Response (DoR)

    Defined as the time from the date of the first response, as determined by the Investigator, to the date of the first PD (based on the International Myeloma Working Group [IMWG] response criteria) or death, whichever occurs first. DoR will be determined only for patients who have achieved ≥PR.

    Measured: From time response is achieved to progressive disease (PD), or death, whichever comes first. Maximum time period 42 months.

  6. Safety

    i.e. Adverse Events (AEs), Treatment-Emergent Adverse Events (TEAEs), Serious Adverse Events (SAEs).

    Measured: Study treatment initiation until 30 days after last study treatment. Maximum time period 42 months.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Isatuximab, Pomalidomide and Dexamethasone in people with Multiple Myeloma and Renal Impairment, run by Hellenic Society of Hematology at 6 sites in Greece.

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 21 inclusion and 29 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: status not confirmed, as of the sponsor's last update on 28 Mar 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites in Greece. 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 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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Maria Pagoni, Prof (+302107211806, info@eae.gr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Overall Response Rate (ORR) (time frame: After six months of treatment with isatuximab plus pomalidomide and low-dose dexamethasone). 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 NCT05298683.

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 28 Mar 2022.
