Participant Flow

The study recruited the first participant on 07 December 2020 and the last participant's last visit was completed on 30 March 2023. A total of 193 participants were screened, among which, 166 participants (86.0%) were successfully enrolled into the study from 32 study sites in China

Among the 166 enrolled participants, 165 of them (99.4%) received the study treatment, while only 1 participant (0.6%) did not receive the study treatment. All subjects who received at least 1 dose of study treatment will be included in the safety analysis set, which will be the primary analysis set for all analyses.

Population: 165 subjects who received at least 1 dose of study treatment are included in the analysis.

An immune-mediated adverse event (imAE) is defined as an AESI that is associated with drug exposure and is consistent with an immune-mediated mechanism of action and where there is no clear alternate aetiology.

SECONDARY outcome

Timeframe: 19 months

Population: 165 subjects who received at least 1 dose of study treatment are included in the analysis.

PFS by investigator assessment according to RECIST v1.1 criteria Progression-free survival is defined as the time from first dose of study treatment until the date of objective disease progression or death (by any cause in the absence of progression) regardless of whether the patient withdraws from study therapy or receives another anti-cancer therapy prior to progression. Patients who have not progressed or died at the time of analysis will be censored at the time of the latest date of assessment of investigator. However, if the patient progresses or dies after 2 or more missed visits, the patient will be censored at the time of the latest assessment. If the patient has no evaluable visits or does not have baseline data, they will be censored at the day of first dose unless they die within 2 visits of baseline.

The APF12 is defined as the Kaplan-Meier estimate of PFS (per investigator assessment according to RECIST v1.1 criteria) at 12 months.

SECONDARY outcome

Timeframe: 19 months

Population: 165 subjects who received at least 1 dose of study treatment are included in the analysis.

Objective Response Rate is defined as the number (%) of patients with measurable disease with at least 1 visit response of CR or PR. Data obtained up until progression or last evaluable assessment in the absence of progression will be included in the assessment of ORR. Any CR or PR which occurred after a further anti-cancer therapy was received will not be included in the numerator for the ORR calculation.

Overall survival is defined as the time from the date of first dose of study treatment until death due to any cause. Any patient not known to have died at the time of analysis will be censored based on the last recorded date on which the patient was known to be alive.

SECONDARY outcome

Timeframe: 19 months

Population: Duration of response is only calculated for patients who have a best overall tumor response of CR or PR before further anti-cancer therapy after first dose.

Duration of response is defined as the time from the date of first documented response until the date of documented progression or death in the absence of disease progression. The end of response should coincide with the date of progression or death from any cause used for the PFS endpoint. The time of the initial response will be defined as the latest of the dates contributing towards the first visit response of PR or CR.
