Clinical Trial Summary

Immunotherapy (IO), such as treatment with anti-PD-1, PD-L1, or CTLA-4 inhibitors, is a rapidly expanding treatment for multiple metastatic cancers with improved survival for certain cancers. However, the optimal duration of immunotherapies is currently unknown. Our hypothesis is that a reduced dose intensity of IO could be as effective as the current standard treatment in term of prevention of the disease progression. If proved right, this study will have a positive medico-economic impact by reduction of the costs associated with the treatment and the toxicity, and an increase of the patients' quality of life.

Description:

Immunotherapy (IO) is a rapidly expanding treatment for multiple metastatic cancers with improved survival for certain cancers. For currently approved immunotherapies such as PD-1 / PD-L1 inhibitors and anti-CTLA-4, the rhythm and duration of treatment are recommended until disease progression or unacceptable toxicity. However, the optimal duration of these treatments is currently unknown.

No major dose-dependent effect of anti-PD-1 have been observed and whether the frequency of infusion of IO could improve response or maintain efficacy. Moreover, phase I studies have shown that saturation of the target (PD-1 or PD-L1) can persist far beyond the serum half-life of the IO and 3-monthly infusions of an anti-PD-1 antibody could potentially generate the same level of activity as infusions administered every 2 weeks.

In silico modeling studies have suggested that alternate scheduling with IO couldn't compromise the efficacy of the treatment. Indeed, prolonged half-lives of IO drugs, time-varying clearance plus plasma concentrations far above the threshold associated with maximal target-engagement, suggest that the rhythm of administration of IO could be slowed down.

Without substantial international data for responding patients, apart metastatic melanoma in complete response, patients and physicians are afraid of stopping treatment, by fear of relapse. Over-treatment with IO may be toxic and inefficient. The rising cost of cancer care in the era of immunotherapy is of great concern for public and private payers around the world.

Chronic administration has important consequences for patients and health systems, with multiple medical visits and the risk of chronic, progressive and sometimes fatal toxicities induced by immunotherapy.

This is a pragmatic and strategic study challenging the routine practice which compares for the first time in a randomized phase III study, the standard administration of IO versus the same agent administered each three months in patients with metastatic cancer in partial or complete response after 6 months of standard IO ( except melanoma in CR).

If our hypothesis of non-inferiority of PFS with a reduced dose intensity of IO is verified, this could replace standard treatment and have a positive medico-economic impact, allowing, on the one hand, a reduction of the costs associated with the treatment and the toxicity, and on the other hand, an increase of the patients' quality of life.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Progression-free survival (PFS)	The progression-free survival is the length of time during and after the treatment of a disease that a patient lives with the disease but it does not get worse.	From randomization to disease progression or death, up to 3 years
Secondary	Cost-effectiveness analysis of the proposed therapeutic strategy	Incremental cost-effectiveness ratio (ICER) expressed as a cost per quality-adjusted life year (QALY) gained at 36 months.	3 years
Secondary	Immune progression-free survival (iPFS)	The progression-free survival is the length of time during and after the treatment of a disease that a patient lives with the disease but it does not get worse (Immune disease progression (iPD)). iPD will be determined locally by the investigator through the use of iRECIST in case of lesions identified at Baseline.	From randomization to disease progression or death, up to 3 years
Secondary	Objective response rate (ORR)	Objective response rate (ORR) defined as the percentage of patients with a confirmed complete response (CR) or partial response (PR) as assessed by the investigator using RECIST v1.1 at 12 and 24 months post-randomization.	From randomization to 12 and 24 months post-randomization
Secondary	Overall survival (OS)	The overall survival is the length of time from randomization that patients enrolled in the study are still alive.	From randomization to death from any cause, up to 3 years
Secondary	Duration of response (DoR)	Duration of response (DoR) defined as the time from randomization to first documented response until disease progression or death, whichever occurs first.	From randomization to disease progression or death, up to 3 years
Secondary	Quality of life questionnaire - Core 30 (QLQ-C30)	Developed by the EORTC, this self-reported questionnaire assesses the health-related quality of life of cancer patients in clinical trials.; The questionnaire includes five functional scales (physical, everyday activity, cognitive, emotional, and social), three symptom scales (fatigue, pain, nausea and vomiting), a health/quality of life overall scale, and a number of additional elements assessing common symptoms (including dyspnea, loss of appetite, insomnia, constipation, and diarrhea), as well as, the perceived financial impact of the disease.; All of the scales and single-item measures range in score from 0 to 100. A high scale score represents a higher response level.	At inclusion visit (pre-randomization) and 3, 6, 9, 12, 15, 18, 24, and 36 months post-randomization
Secondary	The Developed 5-level version of EQ-5D (EQ-5D-5L) questionnaire	Developed by the EuroQol group, the self-reported questionnaire assesses the health-related quality of life of cancer patients in clinical trials consists of a descriptive system and a visual analogue scale (VAS).; The EQ-5D-5L descriptive system comprises five dimensions (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression), each dimension has 5 levels. This questionnaire provide a 5-digit score which generate a health state profile. The VAS records the patient's self-rated health on a vertical visual analogue scale where the score range from 100 (Best imaginable health state) to 0 (Worst imaginable health state). The VAS is used as a quantitative measure of health outcome that reflects the patient's own judgement.	At inclusion visit (pre-randomization) and 3, 6, 9, 12, 15, 18, 24, and 36 months post-randomization
Secondary	Hospital anxiety and depression scale (HADS)	The HADS is a 14 items questionnaire: 7 items related to anxiety and 7 items related to depression scored on a scale. Scores for items in each subscale of the HADS are summed to produce an anxiety score (HADS-A) or a depression score (HADS-D), or can be added to produce a total score corresponding to emotional distress (HADS-T). Each item is rated on a 4-point Likert scale (1 = "not at all", 2 = "a little", 3 = "quite a bit", and 4 = "very much"), for a total score ranging from 0-21 for each subscale. The entire scale (emotional distress) range from 0 to 42, with higher scores indicating more distress.	At inclusion visit (pre-randomization) and 3, 6, 9, 12, 15, 18, 24, and 36 months post-randomization
Secondary	Fear of relapse questionnaire	The Fear of relapse questionnaire is a self-reported questionnaire aiming to better understand how these concerns of fear of relapse by patients manifest themselves.; The questionnaire contains 32 items rated on a five-point Likert-type scale (0 = "never", 1 = "seldom ", 2 = "sometimes", 3 = "often", and 4 = "always"). For all items, higher scores indicate more severe fear of relapse.	At inclusion visit (pre-randomization) and 3, 6, 9, 12, 15, 18, 24, and 36 months post-randomization
Secondary	Safety profile	The National Cancer Institute-Common Terminology Criteria for Adverse Events version 5 (NCI-CTCAE v5) is widely accepted in the community of oncology research as the leading rating scale for adverse events. This scale, divided into 5 grades (1 = "mild", 2 = "moderate", 3 = "severe", 4 = "life-threatening", and 5 = "death") determined by the investigator, will make it possible to assess the severity of the disorders.	At 12 months and 3 years post-randomization
