About this study

Official title: A Phase I/II, Open-Label, Multicenter Study of the Safety, Efficacy and Immune Response of Histamine Dihydrochloride and Low-dose Interleukin-2 in Chronic Myelomonocytic Leukemia (CMML)

Enrolled subjects will receive histamine dihydrochloride (HDC; Ceplene®) and/or IL-2 (Proleukin®) subcutaneously (s.c.) twice daily (BID) in 3-week periods followed by 3- or 6 week rest periods.

All subjects will be assigned to one of three consecutive cohorts, each comprising five patients.

Read more

Cohort 1 will receive HDC without IL-2 for the first treatment cycle, to enable the assessment of short-term impact of HDC alone on clonal and immunological markers. For all remaining cycles the combination of HDC and IL-2 will be given.

Cohort 2 will receive the combination of Ceplene and Proleukin in all cycles. After all patients in cohorts 1 and 2 have completed 4 treatment cycles, immunological and clinical response and toxicity will be evaluated. On the basis of the results for the first 4 cycles of cohorts 1 and 2, a third cohort of 5 patients will be enrolled receiving either the combination of HDC/IL-2 or HDC alone.

In case of a beneficial response* after 4 cycles, treatment may be continued to a total of 10 cycles. Treatment cycles 5-10 will comprise 3 weeks of treatment and 6-week rest periods.

IL-2 will be administered s.c., 1 µg/kg (=16400 IU/kg) body weight twice daily (BID) during treatment periods. Ceplene® will be administered s.c. 0.5 mg BID after IL-2. The patient or a family member/significant other will be instructed to administer injections of both study drugs to allow safe treatment at home.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Cohort 1, Ceplene® and Proleukin®, Cohort 2, Ceplene® and Proleukin® and Cohort 3, Ceplene® and Proleukin® in people with Leukemia, Myelomonocytic, Chronic, run by Vastra Gotaland Region at 2 sites in Sweden.

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 21 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 19 Dec 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in 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 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?

Results are not available in the source record.

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

Contact Lars Möllgård, PhD, MD (+46 (0)31 3427344, lars.mollgard@vgregion.se), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Adverse events as defined by CTCAE v4.03. (time frame: 3 weeks after last treatment cycle). 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 19 Dec 2017.
