Number of Participants With Treatment-Emergent Adverse Events (TEAEs) |
An adverse event (AE) was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. Drug-related TEAEs: TEAEs with possible, probable, definite, or missing relationship to study medication (X4P-001 or Nivolumab). Serious AEs: death, a life-threatening AE, inpatient hospitalization or prolongation of existing hospitalization, persistent or significant disability or incapacity, a congenital anomaly or birth defect, or an important medical event that jeopardized participant and required medical intervention to prevent 1 of the outcomes listed in this definition. TEAEs were defined as events occurring on or after the first dose of study drug through 30 days after the last dose. Any TEAEs included both serious and non-serious TEAEs. A summary of other non-serious AEs and all serious AEs, regardless of causality, is located in Reported AE section. |

Objective Response Rate (ORR): Percentage of Participants With Objective Response, Evaluated Using Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1 |
ORR was defined as percentage of participants with best overall response of complete response (CR) or partial response (PR). CR: Disappearance of all target and non-target lesions. Any pathological lymph nodes (whether target or non-target) with a reduction in short axis to less than (<) 10 millimeters (mm). PR: At least a 30 percent (%) decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. |
From administration of first dose of study medication (Day 1) until disease progression, study completion or early termination (up to 15 months) |
|
Secondary |
Duration of Objective Response (DOR), Evaluated Using RECIST Version 1.1 |
DOR was defined as the time from first CR or PR whichever comes first until the time of disease progression by RECIST v1.1 or death due to any cause. CR: Disappearance of all target and non-target lesions. Any pathological lymph nodes (whether target or non-target) with a reduction in short axis to <10 mm. PR: At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. Disease progression: At least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study. In addition to the relative increase of 20%, the sum also demonstrated an absolute increase of at least 5 mm. Unequivocal progression of existing non-target lesions. The appearance of 1 or more new lesions was also considered progression. |
Time from first CR or PR until the time of disease progression or death due to any cause (up to 15 months) |
|
Secondary |
Time to Objective Response, Evaluated Using RECIST Version 1.1 |
Time to objective response was defined as time from first administration of combination regimen to first CR or PR whichever comes first. CR: Disappearance of all target and non-target lesions. Any pathological lymph nodes (whether target or non-target) with a reduction in short axis to <10 mm. PR: At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. |
From administration of first dose of study medication (Day 1) until first appearance of CR or PR (up to 15 months) |
|
Secondary |
Disease Control Rate: Percentage of Participants With CR or PR or Stable Disease (SD), Evaluated Using RECIST Version 1.1 |
Disease control rate was defined as percentage of participants with best overall response of CR or PR or SD. CR: Disappearance of all target and non-target lesions. Any pathological lymph nodes (whether target or non-target) with a reduction in short axis to <10 mm. PR: At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. SD: Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease (PD), taking as reference the smallest sum diameters while on study. PD: At least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study In addition to the relative increase of 20%, the sum also demonstrated an absolute increase of at least 5 mm. Unequivocal progression of existing non-target lesions. The appearance of 1 or more new lesions was also considered progression. |

Progression Free Survival (PFS), Evaluated Using RECIST Version 1.1 |
PFS was defined as the time from first administration of study medication until objective tumor progression or death from any cause. Tumor progression: At least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study In addition to the relative increase of 20%, the sum also demonstrated an absolute increase of at least 5 mm. An unequivocal progression of existing non-target lesions or the appearance of 1 or more new lesions was also considered progression. |
From administration of first dose of study medication (Day 1) until disease progression or death from any cause (up to 15 months) |

Time to Progression (TTP), Evaluated Using RECIST Version 1.1 |
TTP was defined as the time from first administration of study medication until objective tumor progression.

Unequivocal progression of existing non-target lesions or the appearance of 1 or more new lesions was also considered progression. |
