Study of Irinotecan Liposome Injection (ONIVYDE®) in Patients With Small Cell Lung Cancer

An adverse event (AE) was any untoward medical occurrence in a participant following or during exposure to a study treatment, whether or not causally related to the study treatment. An undesirable medical condition could be symptoms, signs or abnormal results of an investigation. An SAE was any AE that: resulted in death; was life-threatening; required hospitalization or prolongation of existing hospitalization; resulted in persistent or significant disability or incapacity; resulted in congenital anomaly or birth defect; or was medically important. A TEAE was any AE that occurred or worsened on or after the day of first dose of study treatment and within 30 days after discontinuation of study treatment.

A TEAE was considered as DLT if it occurred during the safety evaluation period (i.e. first 28 days of treatment or 14 days after the second dose of study treatment if there was a treatment delay due to non-DLT related reasons) and were deemed related to the study treatment by the investigator. The determination of whether an Adverse Event was considered a Dose Limiting Toxicity was made by the Safety Review Committee (SRC) comprising the Part 1 Investigators and the Medical Monitor(s) of the Sponsor.

The OS was defined as the time from randomization date to the date of death from any cause. In the absence of confirmation of death, survival time was censored at the last date the participant was known to be alive. The OS was calculated using Kaplan-Meier technique. Following end of treatment participant and/or family was contacted by telephone every month to assess vital status.

The ORR was defined as the percentage of participants with a best overall response (BOR) characterized as either a complete response (CR) or partial response (PR) recorded from date of first dose of study treatment until documented PD or death. ORR analysis was based on BOR using RECIST v1.1 per investigator assessment. Per RECIST v1.1, CR is disappearance of all target lesions; PR is >=30% decrease in the sum of the longest diameter of target lesions; and overall response = CR + PR. Per protocol, participants had computed tomography (CT)-scans and brain magnetic resonance imaging (MRI) every 6 weeks to measure tumor lesion size. This was continued throughout treatment until PD or commencement of new anti-neoplastic therapy.

The PFS was defined as time from first dose of study treatment to the first documented objective PD using RECIST v1.1 or death due to any cause, whichever occurs first. Per RECIST 1.1, progression is defined as at least 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions. The PFS was calculated using Kaplan-Meier technique. Per protocol, participants had CT-scans and brain MRI every 6 weeks to measure tumor lesion size. This was continued throughout treatment until PD or commencement of new anti-neoplastic therapy.

The PFS was defined as time from randomization to first documented objective PD using RECIST 1.1 (or response assessment in neuro-oncology brain metastases [RANO-BM] criteria for central nervous system [CNS] lesions) as assessed by blinded independent central review (BICR) or death due to any cause, whichever occurred first. Per RECIST 1.1, progression is defined as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions. The PFS was calculated using Kaplan-Meier technique. Per protocol, participants had CT-scans and brain MRI every 6 weeks to measure tumor lesion size. This was continued throughout treatment until PD or commencement of new anti-neoplastic therapy.

The ORR was defined as percentage of participants with a BOR characterized as either a CR or PR, recorded from randomization until documented PD or death relative to the total number of participants. ORR analysis was based on BOR assessed by BICR using RECIST v1.1. Per RECIST v1.1, CR is disappearance of all target lesions; PR is >=30% decrease in the sum of the longest diameter of target lesions; and overall response = CR + PR. Per protocol, participants had CT-scans and brain MRI every 6 weeks to measure tumor lesion size. This was continued throughout treatment until PD or commencement of new anti-neoplastic therapy.

The DoR was defined as time from the first documented objective response (CR or PR, whichever was earlier) to the date of first documented PD or death due to any cause. The DoR analysis was based on BOR assessed by BICR using RECIST v1.1. Per RECIST v1.1, CR is disappearance of all target lesions and PR is >=30% decrease in the sum of the longest diameter of target lesions. The DoR was calculated using Kaplan-Meier technique. Per protocol, participants had CT-scans and brain MRI every 6 weeks to measure tumor lesion size. This was continued throughout treatment until PD or commencement of new anti-neoplastic therapy.

Time to OR as per RECIST v1.1 criteria according to BICR was defined as time from the date of randomization to the date of first documented objective tumor response (CR or PR, whichever was first). Per RECIST v1.1, CR is disappearance of all target lesions; PR is >=30% decrease in the sum of the longest diameter of target lesion. Participants with a new anti-cancer therapy prior to OR were censored at the last tumor assessment prior to new anti-cancer therapy. Per protocol, participants had CT-scans and brain MRI every 6 weeks to measure tumor lesion size. This was continued throughout treatment until PD or commencement of new anti-neoplastic therapy.

The EORTC QLQ-LC13 is a lung cancer specific module used in conjunction with EORTC QLQ-C30 and covers typical symptoms of lung cancer (cough, pain, dyspnea, sore mouth, peripheral neuropathy, hair loss). Scores range from 0-100 and a high score represents a high level of symptomatology/problems/worse QoL. Baseline was defined as the last non-missing measurement taken prior to reference start date. Change from baseline in dyspnea scale was calculated regardless of premature study treatment discontinuation. Participants completed these questionnaires on an electronic tablet every 6 weeks during treatment and it was continued until PD or commencement of new anti-neoplastic therapy.
