Study Endpoints

Primary Endpoints

Number of Participants With Treatment Emergent Adverse Events (TEAEs) and Treatment Related AEs (TRAEs)
Baseline in parent study (NCT02517398, NCT02699515, NCT04246489, NCT03840915, NCT03631706, NCT04551950, NCT03833661 and NCT04066491) upto end of current rollover study (approximately assessed upto a maximum of 9 years, 6 months, 22 days)

An AE is any untoward medical occurrence in a patient or clinical study participant, temporally associated with the use of study intervention, whether considered related to the study intervention or not. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of study intervention. TEAEs were defined as AEs emerging or worsening after start of treatment until 30 days after end of treatment. TRAE was defined as any AE considered as related to study treatment.

Number of Participants With Confirmed Objective Response According to Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST v1.1) as Assessed by Independent Review Committee (IRC)
Time from first treatment up to 688 days

Confirmed objective response was defined as the number of participants with a confirmed objective response of complete response (CR) or partial response (PR). CR: Disappearance of all evidence of target and non-target lesions. PR: At least 30% reduction from baseline in the sum of the longest diameter (SLD) of all lesions. Confirmed CR = at least 2 determinations of CR at least 4 weeks apart and before progression. Confirmed PR = at least 2 determinations of PR at least 4 weeks apart and before progression (and not qualifying for a CR). Confirmed objective response was determined according to RECIST v1.1 and as adjudicated by IRC.

Evaluation of Objective Tumour Response
From the date of screening to radiographically documented progression according to RECIST 1.1, assessed up to 2 years

To evaluate the objective tumor response (ORR) to bintrafusp alfa in previously treated R/M NPC patients per response evaluation criteria of solid tumor (RECIST) version 1.1

NameTypeDescription
Bintrafusp alfaDRUGParticipants who are continuing treatment with bintrafusp alfa and were previously assigned to a bintrafusp alfa dose based on body weight which is (i.e.) milligrams per kilogram (mg/kg) dose in a parent protocol, will receive an intravenous infusion of bintrafusp alfa at the dose specified based upon the participant's parent protocol once every 2 week or, 2400 mg once every 3 weeks. Participants who are entering the rollover study after discontinuation of treatment in a parent study will receive bintrafusp alfa at a dose of either 1200 or 2400 mg once every 2 weeks or 2400 mg once every 3 weeks until confirmed disease progression, death, unacceptable toxicity or study withdrawal.
