Primary Outcome Measures
NameTimeMethod
Number of Participants According to Tumor Response of Primary Tumor (Soft Tissue)From start of lorlatinib treatment until CR, PR, SD or PD, up to maximum of 36.2 months of treatment (data was retrieved and evaluated retrospectively during approximately 18 months of this study)

Tumor response was collected by the data collection tool (DCT) and responses included complete response (CR), partial response (PR), stable disease (SD) and progressive disease (PD). As per International Neuroblastoma Response Criteria (INRC): CR=\<10 millimeter (mm) residual soft tissue at primary site and complete resolution of metaiodobenzylguanidine (MIBG) or \[18F\] fluorodeoxyglucose (FDG)/positron emission tomography (PET) uptake (for MIBG-nonavid tumors) at primary site; PR: \>=30% decrease in longest diameter (LD) of primary site \& MIBG or FDG-PET uptake at primary site stable, improved, or resolved; SD: neither sufficient shrinkage for PR nor sufficient increase for PD at the primary site. PD greater than 20% increase in longest diameter taking as reference the smallest sum on study (this included the baseline sum if that was the smallest on study) and minimum absolute increase of 5 mm in longest dimension. One participant may have more than one tumor response.

Duration of treatment was derived as treatment stop date minus treatment start date plus 1. Participants continuing treatment at the data cut-off date were censored based on the last recorded date when the participant was known to be continuing treatment prior to the data cut-off date.

Overall SurvivalFrom date of first dose of lorlatinib until date of death or censoring date, up to maximum (max) of 36.2 months (M) of treatment (data was retrieved and evaluated retrospectively during approximately (approx.) 18 months of this study)

Overall survival was derived as date of death minus treatment start date plus 1. Participants who had not died were censored at the date of last contact prior to the data cut-off date.

Number of Participants Reporting Adverse Events, Treatment-Related Adverse Events, Serious Adverse Events and Treatment-Related Serious-Adverse EventsFrom start of first dose of lorlatinib/date of informed consent(participant treated with lorlatinib) to atleast 28 day after last dose of lorlatinib to max 36.2M of treatment(data was retrieved, evaluated for approx. 18 month)

An AE is any untoward medical occurrence in participants administered a medicinal product. The event need not necessarily have a causal relationship with the product treatment or usage. A SAE is any untoward medical occurrence in a participant administered a medicinal or nutritional product at any dose that: resulted in death, was life-threatening, required participant hospitalization or prolongation of hospitalization, resulted in persistent or significant disability/incapacity (substantial disruption of the ability to conduct normal life functions) and resulted in congenital anomaly/birth defect. Relatedness to treatment was determined by investigator.
