About this study

Official title: Phase IIa Trial of PD-L1 Peptide Vaccination as Monotherapy in High Risk Smoldering Multiple Myeloma

This study is evaluating a new vaccine against PD-L1 as a possible treatment for high-risk smoldering multiple myeloma.

Read the detailed description

Smoldering multiple myeloma is an asymptomatic disorder with an annual risk of 10% of progression to the incurable cancer multiple myeloma. While many patients live for many years without progression, high risk patients have a median risk of progression of 29 months. No therapy has been approved for this indication. New treatments with limited adverse events are in high demand for this unmet medical need. An effective peptide vaccine would represent an ideal candidate, since vaccines generally have very low levels of side effects.

This study will explore if vaccination against the immune checkpoint molecule PD-L1 leads to responses in patients with high risk smoldering myeloma. PD-L1 is thought to play a role in the rate of progression from smoldering myeloma to symptomatic myeloma. Targeting this pathway with little risk of adverse events would potentially prevent or delay progression to symptomatic myeloma.

What participants receive

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

  • PD-L1 peptideBiological

    Also called IO103

    PD-L1 peptide (100 micrograms) emulsified with the adjuvant Montanide ISA-51 given subcutaneously 10 times every second week over the course of 26 weeks including a five-week break.

What is being measured

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

  1. Overall response rate

    Overall response rates (ORR) defined by IMWG criteria as PR+VGPR+CR+sCR during treatment and two weeks after end of treatment per patient.

    Measured: Planned analysis cut-off per patient: two weeks after last vaccination.

Secondary outcomes (5)
  1. Immunogenicity of the PD-L1 vaccine

    Blood, skin biopsies and bone marrow samples will be assessed with ELISPOT assays for levels of immune response to the vaccine.

    Measured: Samples taken before, during and two weeks after last vaccination.

  2. Incidence of Treatment Emergent Adverse Events

    Safety analysis will be conducted using the Safety Population defined as any patient receiving one dose of study treatment. For toxicity reporting, all adverse events and laboratory abnormalities will be graded and analyzed using CTCAE version 4 as appropriate.

    Measured: Planned analysis cut-off per patient: two weeks after last vaccination

  3. Progression-free survival (PFS)

    PFS from diagnosis is defined as the time from diagnosis to the disease progression or death from any cause. Patients who have not progressed or died are censored at the date last known progression-free. This will be compared with published progression rates.

    Measured: Planned analysis 2 years and 5 years post initiation of therapy.

  4. Time to progression (TTP)

    Time from diagnosis of SMM to progression to symptomatic myeloma compared to historical controls. Progression is defined as biochemical or diagnostic progression in accordance with the 2014 IMWG criteria for diagnosis of multiple myeloma which includes the classic CRAB-criteria as well as: Clonal bone marrow plasma cell percentage ≥ 60%, Free light chain ratio ≥ 100 (Involved FLC level must be ≥ 100mg/L),> 1 focal lesion on MRI studies (at least 5 mm in size)

    Measured: Planned analysis 2 years and 5 years post initiation of therapy.

  5. Overall survival (OS)

    OS from diagnosis is defined as the time from diagnosis to the death of the patient.

    Measured: Planned analysis 2 years and 5 years post initiation of therapy.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing PD-L1 peptide in people with Smoldering Multiple Myeloma, run by Lene Meldgaard Knudsen at 1 site in Denmark.

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 25 inclusion and 23 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 15 Apr 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Denmark. 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?

The study was stopped early (reason given: Insufficient recruitment within planned enrolmentperiod.). 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?

Overall response rate (time frame: Planned analysis cut-off per patient: two weeks after last vaccination.). 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 15 Apr 2022.
