About this study

Official title: Open Label 1b/2a Trial of a Combination of IPH2201 and Ibrutinib in Patients With Relapsed, Refractory or Previously Untreated Chronic Lymphocytic Leukemia

Combination study of monalizumab (IPH2201) with Ibrutinib in relapsed, refractory or previously untreated Chronic Lymphocytic Leukemia (CLL) patients in 2 parts :

phase 1 : a 3+3 design to assess the Maximum Tolerated Dose (MTD)
phase 2: to evaluate the anti-leukemic activity of the combination

Read the detailed description

This trial was designated to test the hypothesis that the combination of ibrutinib and IPH2201 will result in a substantial complete response (CR) rate, especially CR without minimal residual disease (MRD), as this has been shown to be associated with long-term clinical benefit.

Up to 45 patients were planned to be enrolled. During the phase 1 part a 3+3 dose escalation design was employed. Four doses were planned to be assessed if the Maximum Tolerated Dose (MTD) was not previously reached: 1, 2, 4 and 10 mg/kg.

During phase 2 part, patients received monalizumab in combination with ibrutinib; monalizumab was given at the dose recommended upon completion of the phase I portion.

The primary objective of the phase 1 was to assess the safety of monalizumab given intravenously as a single agent and in combination with ibrutinib in patients with relapsed, refractory or previously untreated Chronic Lymphocytic Leukemia.

The primary objective of the phase 2 was to evaluate the anti-leukemic activity of the combination of monalizumab and ibrutinib in patients with relapsed, refractory or previously untreated Chronic Lymphocytic Leukemia.

Conditions: Chronic Lymphocytic Leukemia

What participants receive

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

monalizumabDrug
Also called Anti-NKG2A, IPH2201
During phase 1, patients received monalizumab, IV, at the dose of 1, 2 or 4mg/kg, as a single agent during 4 weeks and thereafter combined with ibrutinib 420 mg, orally, once daily, during 52 weeks.
During phase 2, patients received monalizumab, IV, at the dose recommended upon completion of phase 1, combined with ibrutinib 420 mg orally, once daily, from the first cycle, during 52 weeks. In both parts of the trial, the first 4 administrations of monalizumab (from week 0 to week 6) occured every 2 weeks. From the 5th administration monalizumab was administered every 4 weeks.

What is being measured

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

Number of Dose Limiting Toxicities
Number of dose-limiting toxicities, measured during the phase 1, dose escalation, part of the study.
Measured: 8 weeks
Rate of Complete Response (CR)
The rate of complete response (CR) was evaluated using the International Workshop on Chronic Lymphocytic Leukemia (IWCLL) grading scale and confirmed by a bone marrow biopsy. Per International Workshop on Chronic Lymphocytic Leukemia (IWCLL), Complete Response (CR) is defined as lymphocytes <4x109/l, absence of lymphadenopathy, hepatomegaly and splenomegaly at CT scan, no constitutional symptoms, no cytopenia, normocellular bone marrow. Partial Response (PR) is a reduction > 50% in lymphocytes, lymphadenopathy, spleen or liver, no cytopenia. PD if appearance of any new lesion, or increase in lymphocytes > 50%, or occurrence of cytopenia attributable to CLL.
Measured: CR assessed 52 weeks after the beginning of combination treatment

Secondary outcomes (4)

Best Overall Response / Remission Rates
Measure of best overall response at any time during the study. cCR: confirmed complete response/remission; uCR: unconfirmed complete response / remission; PR: partial response/remission; SD: stable disease; PD: progressive disease.
Per International Workshop on Chronic Lymphocytic Leukemia (IWCLL), Complete Response (CR) is defined as lymphocytes <4x109/l, absence of lymphadenopathy, hepatomegaly and splenomegaly at CT scan, no constitutional symptoms, no cytopenia, normocellular bone marrow. Partial Response (PR) is a reduction > 50% in lymphocytes, lymphadenopathy, spleen or liver, no cytopenia. PD if appearance of any new lesion, or increase in lymphocytes > 50%, or occurrence of cytopenia attributable to CLL.
In order to have a confirmed CR (cCR), the CR must be confirmed by a scan and a bone marrow assessment assessed at least 2 months after the first occurrence of CR. Otherwise it would be an unconfirmed CR (uCR).
Measured: From beginning of study drug treatment to the end of study (up to 24 months)
Duration of Remission
The duration of remission (DOR) is defined as the time from the date of first evaluation of the remission (cCR, uCR or PR) to the first documentation of progressive disease, relapsed disease or death. In case an assessment of progressive / relapsed disease or death does not exist, the DOR was censored at the time of the last disease assessment date. The DOR was calculated only for the patients with a remission that was assessed at 52 weeks.
Measured: Up to 24 months
Progression Free Survival
The Progression Free Survival (PFS) is defined as the time from first dose administration until the occurrence of progressive disease, relapsed disease or death from any cause. Patients without an event at the time of the analyse were censored at his or her last disease assessment date. Patients with no post-Baseline assessment were censored at the day of the first dose administration.
Measured: Up to 24 months
Overall Survival
The overall survival (OS) is defined as the time from first dose administration until death from any cause. Alive patients were censored at the most recent date they were known to be alive. Subjects with no assessment post-Baseline were censored at the day of the first dose administration.
Measured: Up to 24 months.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing monalizumab in people with Chronic Lymphocytic Leukemia, run by Innate Pharma at 1 site in United States.

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 10 inclusion and 14 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 Dec 2019. 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 United States. 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?

Yes. Results are posted in the registry (first posted 17 Dec 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Number of Dose Limiting Toxicities (time frame: 8 weeks). 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 NCT02557516.

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 Dec 2019; AzTrials last refreshed its copy on 6 Nov 2026.
