This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing This study
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.

Summary

This trial is for people with advanced cancers who have already responded well to 6 months of standard immunotherapy. It compares continuing the same drugs at the usual frequency versus giving them every 3 months. The goal is to see if the reduced schedule can prevent cancer progression just as effectively while lowering side effects and treatment costs.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
immunotherapy drugs (checkpoint inhibitors) given at reduced frequency
What this could lead to
If successful, this could mean many patients with advanced cancers need fewer hospital visits for immunotherapy, reducing side effects and costs without compromising disease control.
What could go wrong
This is a large phase 3 trial, but reducing treatment frequency might allow some cancers to progress faster. Results will take years to confirm.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Patients must have signed a written informed consent form prior to any trial specific procedures. 2. Patient aged ≥18 years old. 3. Metastatic disease (or locally advanced disease not suitable for local treatment) of initial tumor histologically confirmed including: lung cancer, renal cell cancer, head and neck cancer, urothelial carcinoma, triple negative breast cancer, Merkel cancer, hepatocellular carcinoma, melanoma, colorectal carcinoma with microsatellite instability \[MSI\], esophageal squamous cell carcinoma, endometrial carcinoma,cervical cancer, gastric/gastro-oesophageal junction adenocarcinoma, basal cell carcinoma or squamous skin carcinoma. 4. Patients in partial or complete response after 6 months of standard immunotherapy (whatever the line of therapy) according to the RECIST or PERCIST v1.0 criteria (confirmed by local radiological assessment). For metastatic melanoma only patients in partial response. Patients with metastatic or advanced cancer treated by immunotherapy as maintenance therapy can be included without any lesion at IO initiation. In this case, response after 6 months of standard immunotherapy will be evaluated by the non-appearance of a new lesion. 5. Eligible to maintain the same standard IO treatment. 6. Patient with Eastern cooperative oncology group (ECOG) performance status ≤1. 7. Patients with brain metastases are allowed, provided they are stable according to the following definitions: treated with surgery or stereotactic radiosurgery and without evidence of progression prior to randomization and have no evidence of new or enlarging brain metastases. 8. Patients treated by IO previously combined with chemotherapy are allowed. 9. Patients with Tyrosine Kinase Inhibitor (TKI)-IO or pemetrexed-IO or bevacizumab-IO are allowed. 10. Evidence of post-menopausal status, or negative urinary or serum pregnancy test for pre-menopausal patients. 11. Both sexually active women of childbearing potential and males (and their female partners) patients must agree to use adequate contraception method for the duration of the study treatment and after completing treatment according to the most recent version of the IO Summary of product characteristics (SmPC). 12. Patient is willing and able to comply with the protocol for the duration of the trial including undergoing treatment and scheduled visits, and examinations including follow-up. 13. Patient must be affiliated to a Social Security System. Exclusion Criteria: 1. Metastatic melanoma in complete response. 2. Metastatic renal cell carcinoma with International Metastatic Renal Cell Carcinoma Database (IMDC) favourable-risk treated TKI/IO combination. 3. Hematologic malignancies (leukaemia, myeloma, lymphoma…) 4. Active infection requiring systemic therapy. 5. Patients enrolled in another therapeutic study within 30 days before the inclusion in and during MOIO study. 6. Patient unable to comply with study obligations for geographic, social, or physical reasons, or who is unable to understand the purpose and procedures of the study. 7. Person deprived of their liberty or under protective custody or guardianship.
