Study Details

Study Description

Brief Summary

A prospective, controlled, randomized, multicenter study whose goal is to compare the efficacy of an autophagy inhibitor (GNS561), an anti-NKG2A (monalizumab) and an anti-C5aR (avdoralimab) versus standard of care in patients with advanced or metastatic cancer who have Sars-CoV-2 infection not eligible to a resuscitation unit.

According to their severity level at the time of enrolment, eligible patients will be randomized into 2 different cohorts:

COHORT 1 (mild symptoms or asymptomatic): GNS561 vs anti-NKG2A vs standard of care (randomization ratio 1:1:1).
COHORT 2 (moderate/severe symptoms): anti-C5aR vs standard of care (randomization ratio 1:1).

Arms and Interventions

Arm	Intervention/Treatment
Experimental: Autophagy inhibitor (GNS651)	Drug: Autophagy inhibitor (GNS651) Cohort 1 (arm B): 200mg q.d. orally for 10 consecutive days. If for any reason a treatment is not given within the allowed treatment window (± 12h) it will be cancelled (i.e., missed for that time point), and treatment will be resumed at the next dosing day. Other: Standard of care In cohorts 1 and 2, patients allocated in the standard of care arms should receive best supportive care, as per the investigator's discretion and the local routine practices. With regards to the respiratory symptoms and medical resoures at investigational site, the following should be given according to the patient's condition: oxygen supplementation, non-invasive ventilation, invasive ventilation, antibiotherapy, vasopressor support, renal replacement therapy, or extracorporeal membrane oxygenation. Additional care and medications should be administered in the patient's best interest.

Outcome Measures

Primary Outcome Measures

28-day survival rate [28 days from randomization]
28-day survival rate, defined by the proportion of patients still alive 28 days after randomization. If vital status at 28 days post randomisation is not available due to early transfer in an external resuscitation unit, patients will be considered as failure at the date of the transfer. Comparison of each experimental arm (GNS561 then monalizumab for cohort1 and avdoralimab for cohort2) to control arm will be performed using a Fisher exact test.

Secondary Outcome Measures

Time to clinical improvement [28 days from randomization]
Time to clinical improvement defined as the time from randomization to an improvement of two points (from the status at randomization) on a seven-category ordinal scale (WHO-ISARIC) or live discharge from the hospital, whichever comes first.
Clinical status [Day 7, Day 14, Day 28]
Clinical status will be assessed using a 7-point ordinal scale : Not hospitalized, no limitations on activities Not hospitalized, limitation on activities; Hospitalized, not requiring supplemental oxygen; Hospitalized, requiring supplemental oxygen; Hospitalized, on non-invasive ventilation or high flow oxygen devices; Hospitalized, on invasive mechanical ventilation or ECMO; Death.
Clinical status [Day 7, Day 14, Day 28]
The NEWS2 score (National Early Warning Score) allocates a score based on six physiological parameters (respiratory rate / oxygen saturation / systolic blood pressure / heart rate / consciousness / temperature). It Determines the degree of illness of a patient and prompts critical care intervention. The total possible score ranges from 0 to 21. The higher the score, the greater the clinical risk. A total score close to 0 corresponds to a low risk and a total score higher than 7 corresponds to a high risk.
Mean change in the ranking on the ordinal scale from baseline to D7, D14 and D28 [Day 7, Day 14, Day 28]
Mean change in clinical status from baseline will be assessed by using a 7-point ordinal scale.
Mean change in the ranking of the NEWS2 score from baseline to D7, D14 and D28 [Day 7, Day 14, Day 28]
Mean change in clinical status from baseline will be assessed by using the NEWS2 score (National Early Warning Score). The NEWS2 score (National Early Warning Score) allocates a score based on six physiological parameters (respiratory rate / oxygen saturation / systolic blood pressure / heart rate / consciousness / temperature). It Determines the degree of illness of a patient and prompts critical care intervention. The total possible score ranges from 0 to 21. The higher the score, the greater the clinical risk. A total score close to 0 corresponds to a low risk and a total score higher than 7 corresponds to a high risk.
Overall survival [3 months (i.e. at the time of last patient last visit)]
Overall survival will be defined by the time from date of randomization until date of death, regardless of the cause. Any patient not known to have died at the time of analysis will be censored based on the last recorded date on which the patient was known to be alive.
