Non-comparative multicentric randomized study to assess long-term benefit of PD-1 inhibition in NSCLC patients who experienced a response between 6 and 12 months after initiation of ICI (immune checkpoint inhibitor PD1/PDL-1 blockade therapy)
Two-arm, non-comparative, prospective, multicentric, randomized study for early discontinuation of immune checkpoint inhibitor PD1/PDL-1 blockade therapy in non-small cell lung cancer patients who achieved objective response between 6 and 12 months after treatment onset.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Standard Arm A: treatment by ICI will be continued | Other | After achieving objective response between 6 and 12 months after treatment onset, for these patients ICI treament will continue as per market authorization |
|
| Experimental Arm B: treatment by ICI will be discontinued | Experimental | After achieving objective response between 6 and 12 months after treatment onset, for these patients first-line or second line regimen should be discontinued. Patients will be followed as per standard management. |

| Measure | Description | Time Frame |
|---|---|---|
| Assessment of the long-term benefit of PD-1 inhibition in NSCLC patients who experienced a response between 6 and 12 months after initiation of ICI | Long-term benefit will be assessed in terms of progression-free rate (PFR) at 12 months after randomization, for each therapeutic strategy | 12 months |
| Measure | Description | Time Frame |
|---|---|---|
| Assessment of secondary resistance in NSCLC patients who experienced a response to PD1/PDL-1 inhibition | The rate of patients who develop progression (as per RECIST v1.1) due to secondary resistance after obtaining a response to PD1/PDL-1 inhibition, independently for each therapeutic strategy | 12 months |

Inclusion Criteria:

At least one lesion that can be biopsied for research purpose.
Age ≥ 18.
Performance status < 2.
Women of childbearing potential must have a negative serum pregnancy test within 7 days prior to registration.
Patient with a social security in compliance with the French law (Loi Jardé).
Patient must be willing and able to comply with scheduled visits, treatment plan, laboratory tests and other study procedures.

|
| ICI treatment continuation | Drug | After achieving objective response between 6 and 12 months after treatment onset, for these patients, first or second line treatment by immune checkpoint inhibitor will be continued until disease progreession or unacceptable toxicity |
|
| Duration of response independently for each therapeutic strategy |
Duration of response (DoR) defined as the time interval between the first response (complete or partial response as per RECIST v1.1) to the time of the first documentation of disease progression |
| Throughout the treatment period, an expected average of 12 months |
| 1-year progression-free survival, independently for each therapeutic strategy | Progression-free survival (PFS) defined as the time interval between the date of randomization and the date of progression or death, whichever occurs first. Progression will be determined according to RECIST v1.1 | 1 year |
| 2-year progression-free survival, independently for each therapeutic strategy | Progression-free survival (PFS) defined as the time interval between the date of randomization and the date of progression or death, whichever occurs first. Progression will be determined according to RECIST v1.1 | 2 years |
| 1-year overall survival, independently for each therapeutic strategy | Overall Survival (OS) defined as the time interval between the date of randomization and the date of death (of any cause) | 1 year |
| 2-year overall survival, independently for each therapeutic strategy | Overall Survival (OS) defined as the time interval between the date of randomization and the date of death (of any cause) | 2 years |
| Safety profile, independently for each therapeutic strategy: Common Terminology Criteria for Adverse Events version 5 | Toxicity graded using the Common Terminology Criteria for Adverse Events version 5 | Throughout the treatment and follow-up period, an expected average of 12 months |
| • To describe retreatment for arm B-patients and subsequent systemic therapies for arm A-patients | Number of patients retreated by ICI will be described in Arm B. Similarly, for arm A-patients, number of patients treated by subsequent systemic therapy will be described | Throughout the treatment and follow-up period, an expected average of 12 months |
| Tumor immune cells levels | Levels of immune cells in tumor will be measured by immunohistochemistry. | At study onset (randomization) and at progression (throughout the treatment and follow-up period, an average of 12 months) |
| Blood cytokines levels | Levels of cytokines in blood will be measured by ELISA | At study onset (randomization) and at progression (throughout the treatment and follow-up period, an average of 12 months) |
| Blood lymphocytes levels | Levels of lymphocytes in blood will be measured by flow cytometry | At study onset (randomization) and at progression (throughout the treatment and follow-up period, an average of 12 months) |
| Blood kynurenine levels | Levels of kynurenine in blood will be measured by ELISA | At study onset (randomization) and at progression (throughout the treatment and follow-up period, an average of 12 months) |
