Study summary

This is a multicenter, open-label, dose-escalation, dose-exploration and dose-expansion study to evaluate the safety, tolerability, antitumor activity, pharmacokinetic (PK), pharmacodynamics, and immunogenicity of durvalumab (MEDI4736) in combination with monalizumab (IPH2201) in adult participants with selected advanced solid tumors and the combination of durvalumab and monalizumab (IPH2201) standard of care systemic therapy with or without biological agent and monalizumab (IPH2201) with biological agent administered to participants with recurrent or metastatic colorectal cancer (CRC).

Read the detailed description

The study consists of 3 parts: dose escalation (Part 1), dose expansion (Part 2), and dose exploration (Part 3). Part 1 will evaluate dose escalation of durvalumab in combination with monalizumab in adult participants with select advanced solid tumor malignancies. Part 2 will evaluate further the identified dose of durvalumab in combination with monalizumab from Part 1 in adult participants with select advanced solid tumor malignancies. Part 3 will evaluate dose exploration of durvalumab in combination with monalizumab and standard of care systemic therapy with or without biological agent, and monalizumab in combination with biological agent in adult participants with CRC.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  1. Participants must have histologic documentation of advanced recurrent or cancer.
  2. Participants must be at the recurrent/metastatic setting, with selected advanced solid tumors.
  3. Participants must have at least one lesion that is measurable by v1.1
  4. Part 3, Dose exploration, CRC participants can be treatment naïve but should not have received more than two in the recurrent/metastatic setting.

Exclusion criteria

Exclusion Criteria

  1. Prior treatment with immunotherapy agents. Prior treatment with antitumor vaccines may be permitted upon discussion with the medical monitor.
  2. Prior participation in clinical studies that include durvalumab alone or in combination, where the study has registrational intent and the analyses for the primary endpoint have not yet been completed
  3. Receipt of any conventional or anticancer therapy within 4 weeks prior to the first dose of study treatment
  4. Any concurrent chemotherapy, immunotherapy, biologic or hormonal therapy for cancer treatment. Concurrent use of hormones for non-cancer-related conditions is acceptable.
Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Metastases

Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.

RECIST

The standard rules for measuring tumours on CT or MRI scans, to tell whether a cancer is shrinking, stable or growing during treatment.

“Measurable disease per RECIST 1.1” usually means at least one tumour 10 mm or more at its longest on a CT scan, or a lymph node 15 mm or more across its short axis.

Line of therapy

A line of therapy is one course of treatment, which may combine several drugs. First-line is the first course given; second-line follows when that stops working or is not tolerated.

“Two prior lines” means two courses that count separately under the study’s rules — not simply two drugs. Ask the study team if you are unsure how yours are counted.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

    Time frame: Screening (Days -28 to -1)

  19. Number of Participants With Human Leukocyte Antigen (HLA)-E Expression in Pretreatment Tumor Biopsies

    The HLA-E expression in pre-treatment tumor biopsies is reported.

Outcome measures

PrimaryNumber of Participants With Treatment Emergent Adverse Events (TEAEs) and Treatment Emergent Serious Adverse Events (TESAEs)

An adverse event (AE) is any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. A serious adverse event (SAE) is an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. The TEAEs are defined as events present at baseline that worsened in intensity after administration of study drug or events absent at baseline that emerged after administration of study drug. Any TEAEs data is inclusive of both serious and other adverse events (non-serious).

Number of participants with positive ADA to monalizumab are reported. Persistent positive is defined as positive at \>= 2 post-baseline assessments (with \>=16 weeks between first and last positive) or positive at last post-baseline assessment. Transient positive is defined as negative at last post-baseline assessment and positive at only one post-baseline assessment or at \>= 2 post-baseline assessments (with \<16 weeks between first and last positive). Treatment-boosted ADA is defined as baseline ADA titer that was boosted to a 4-fold or higher level following drug administration. Treatment-emergent ADA is defined as the sum of treatment-induced ADA (post-baseline positive only) and treatment-boosted ADA.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Feb 2016 to primary completion in Oct 2021, 68 months.

Results were first posted in Mar 2023, 1 year 4 months after primary completion.

Of 127 industry-sponsored phase 1/2 interventional studies under Neoplasm Metastasis, half reached primary completion within 56 months of starting (the median), counting those still running; a quarter within 41 and three quarters within 89. This study's 68 months is above that.

Counting every sponsor, half of 213 studies reached it within 62 months; a quarter within 41 and three quarters within 89.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jun 15, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
