Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Phase 1: Number of Participants Experiencing Treatment-emergent Adverse Events (TEAEs)
Time Frame: From first dose of study treatment (Day 1) up to 30 days post last dose of study treatment; maximum duration of treatment exposure was up to approximately 212 weeks

An adverse event (AE) was any untoward medical occurrence in a participant administered a pharmaceutical product, which did not necessarily have a causal relationship with this treatment. An serious AE (SAE) was any AE that:

  • resulted in death;
  • was life-threatening;
  • resulted in inpatient hospitalization or prolongation of existing hospitalization;
  • resulted in a persistent or significant disability/incapacity;
  • resulted in congenital anomaly/birth defect in the offspring of a participant who received IMPs;
  • constituted an important medical event.

Clinically significant changes in laboratory parameters, vital signs and electrocardiogram results were reported as AEs. A TEAE was defined as an AE observed after starting administration of the specific treatment.

From first dose of study treatment (Day 1) up to 30 days post last dose of study treatment; maximum duration of treatment exposure was up to approximately 212 weeks
Phase 1: Number of Participants Experiencing Dose Changes
Time Frame: From first dose of study treatment (Day 1) up to 30 days post last dose of study treatment; maximum duration of treatment exposure was up to approximately 212 weeks
Dose changes were defined as infusion interruption and dose reduction.
From first dose of study treatment (Day 1) up to 30 days post last dose of study treatment; maximum duration of treatment exposure was up to approximately 212 weeks
Phase 1: Absolute Dose Intensity
Time Frame: From first dose of study treatment (Day 1) up to 30 days post last dose of study treatment; maximum duration of treatment exposure was up to approximately 212 weeks
Absolute dose intensity was calculated as cumulative dose received (mg) / study treatment duration (weeks).
From first dose of study treatment (Day 1) up to 30 days post last dose of study treatment; maximum duration of treatment exposure was up to approximately 212 weeks
Phase 1: Relative Dose Intensity
Time Frame: From first dose of study treatment (Day 1) up to 30 days post last dose of study treatment; maximum duration of treatment exposure was up to approximately 212 weeks
Relative dose intensity was calculated as the cumulative dose received (mg) / initial planned cumulative dose (mg). Initial planned cumulative dose was calculated as the starting dose multiplied by the scheduled number of administrations within the study treatment duration.
From first dose of study treatment (Day 1) up to 30 days post last dose of study treatment; maximum duration of treatment exposure was up to approximately 212 weeks
Phase 1: Number of Participants Experiencing Dose Limiting Toxicities (DLTs)
Time Frame: From first dose of study treatment (Day 1) up to 21 days
A DLT was defined as a clinically relevant AE or abnormal laboratory value of Common Terminology Criteria for Adverse Events Version 5.0 (CTCAE v5.0) ≥ Grade 3 assessed as unrelated to disease, PD, inter-current illness or concomitant medications, which occurs within the first cycle (21 days) of treatment with alomfilimab as single agent or in combination with atezolizumab during the dose escalation part of the study.
From first dose of study treatment (Day 1) up to 21 days
Phase 2: Overall Response Rate (ORR) Per RECIST 1.1
Time Frame: From first dose of study treatment (Day 1) up to the end of the long term follow-up, approximately 162 weeks

ORR was the percentage of participants with a measurable disease at baseline and with a confirmed response of complete response (CR) or partial response (PR) according to RECIST v1.1 as the best response. The response is confirmed by a later scan conducted at least 4 weeks after the initial response is observed. The 95% confidence interval (CI) was calculated using the exact binomial method (Clopper-Pearson).

CR: disappearance of all target and non-target lesions. Any pathological lymph nodes (whether target or non-target) must have had a reduction in short axis to < 10 mm. All lymph nodes must have been non-pathological in size (< 10mm short axis).

PR: at least a 30% decrease in the sum of diameters of target lesions, taking as reference the Baseline sum diameters.

From first dose of study treatment (Day 1) up to the end of the long term follow-up, approximately 162 weeks

Secondary Outcome Measures

Measure Description
Time Frame
Best Overall Response (BOR) Per RECIST 1.1
Time Frame: From first dose of study treatment (Day 1) up to the end of the long term follow-up, approximately 236 and 162 weeks for Phase 1 and 2, respectively

BOR for each participant was defined as the best confirmed response per RECIST 1.1 among all responses recorded from start of treatment until PD, initiation of new anti-cancer therapy, death, or analysis cut-off date, whichever comes first, with responses of:

CR: disappearance of all target and non-target lesions. Any pathological lymph nodes (whether target or non-target) must have had a reduction in short axis to < 10 mm. All lymph nodes must have been non-pathological in size (< 10mm short axis).

PR: at least a 30% decrease in the sum of diameters of target lesions, taking as reference the Baseline sum diameters.

Stable disease (SD): neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD.

PD: at least a 20% increase in the sum of diameters of target lesions. The sum must also demonstrate an increase of at least 5mm. Unequivocal progression of existing non-target lesions.

Not evaluable (NE).

From first dose of study treatment (Day 1) up to the end of the long term follow-up, approximately 236 and 162 weeks for Phase 1 and 2, respectively
Progression-free Survival (PFS) Per RECIST 1.1
Time Frame: From first dose of study treatment (Day 1) up to the end of the long term follow-up, approximately 236 and 162 weeks for Phase 1 and 2, respectively

PFS was calculated as (first documented PD or death due to any cause - first dose date of study drug +1)/30.4375. Participants who were not observed to have progressed or died were censored at the date of the last tumor assessment. Participants who missed two or more sequential assessments were censored at the date of the last tumor assessment before the missed assessments. Participants who started new anti-cancer therapy prior to documented PD were censored at the date of the last tumor assessment prior to the start of the new therapy. Participants who did not have any tumor assessments were censored with a duration of 1 day. PFS was obtained via Kaplan Meier estimation using the Brookmeyer-Crowley method.

PD: at least a 20% increase in the sum of diameters of target lesions. The sum must also demonstrate an increase of at least 5mm. Unequivocal progression of existing non-target lesions.

From first dose of study treatment (Day 1) up to the end of the long term follow-up, approximately 236 and 162 weeks for Phase 1 and 2, respectively
Duration of Response Per RECIST 1.1
Time Frame: From first dose of study treatment (Day 1) up to the end of the long term follow-up, approximately 236 and 162 weeks for Phase 1 and 2, respectively
Duration of response was calculated as (date of the first documentation of PD or to death due to any cause in the absence of PD - date of the first documentation of unconfirmed objective response [CR or PR] + 1]/30.4375. Participants who were not observed to have progressed or died were censored at the date of the last tumor assessment. Participants who missed two or more sequential assessments were censored at the date of the last tumor assessment before the missed assessments. Participants who started new anti-cancer therapy prior to documented PD were censored at the date of the last tumor assessment prior to the start of the new therapy. Participants with no disease assessment (or only had assessments with response = NE) after first study treatment or have baseline or post-baseline assessments where the RECIST criteria could not be applied had their duration of response time censored. Duration of response was obtained via Kaplan Meier estimation.
From first dose of study treatment (Day 1) up to the end of the long term follow-up, approximately 236 and 162 weeks for Phase 1 and 2, respectively
ORR Per iRECIST
Time Frame: From first dose of study treatment (Day 1) up to the end of the long term follow-up, approximately 236 and 162 weeks for Phase 1 and 2, respectively

RECIST 1.1 has been modified to take into consideration the unique response kinetics which have been observed with immunotherapy in some patients where responses to immune therapies may occur after progression has been assessed. ORR was the percentage of participants with a measurable disease at baseline and with a confirmed response of complete immune-response (iCR) or partial immune-response (iPR) according to iRECIST as the best response. The 95% CI was calculated using the exact binomial method (Clopper-Pearson).

iCR: disappearance of all target and non-target lesions. Any pathological lymph nodes (whether target or non-target) must have had a reduction in short axis to < 10 mm. All lymph nodes must have been non-pathological in size (< 10mm short axis).

iPR: at least a 30% decrease in the sum of diameters of target lesions, taking as reference the Baseline sum diameters.

From first dose of study treatment (Day 1) up to the end of the long term follow-up, approximately 236 and 162 weeks for Phase 1 and 2, respectively
PFS Per iRECIST
Time Frame: From first dose of study treatment (Day 1) up to the end of the long term follow-up, approximately 236 and 162 weeks for Phase 1 and 2, respectively

PFS was calculated as (first documented iPD or death due to any cause - first dose date of study drug +1)/30.4375. Participants who were not observed to have progressed or died were censored at the date of the last tumor assessment. Participants who missed two or more sequential assessments were censored at the date of the last tumor assessment before the missed assessments. Participants who started new anti-cancer therapy prior to documented PD were censored at the date of the last tumor assessment prior to the start of the new therapy. Participants who did not have any tumor assessments were censored with a duration of 1 day. PFS was obtained via Kaplan Meier estimation using the Brookmeyer-Crowley method.
