Immune Overall Response Rate
16.7 percent of participants
Interval 8.8 to 19.1

SECONDARY outcome

Timeframe: 3 years

Defined among all treated patients as the time from first dose of study drug until the first date of either disease progression or death due to any cause

Progression Free Survival
4.5 months
Interval 2.0 to
Upper bound was not reached for time to event analysis due to lack of enough events observed in the study population by the end of follow-up. Specifically, due to small sample size to start, compounded by censoring of data, many patients did not have the event. Therefore, the upper bound of the 95% confidence interval could not be calculated.

SECONDARY outcome

Timeframe: 3 years

The number of patients reporting treatment emergent adverse events (TEAEs) defined as an AE that occurs or worsens in the period extending from the first dose of study drug to 30 days after the last dose of study drug in this study

Number of Patient Reporting Treatment-emergent Adverse Events (TEAEs)
8 Participants

SECONDARY outcome

Timeframe: baseline

Population: The planned Fanconi Anemia Triple Stain Immunofluorescence assay could not be completed due to lack of available resources to conduct the assay.

The number of patients with baseline tumor deficiencies in the Fanconi Anemia pathway associated with antitumor responses to the combination as assessed by the Fanconi Anemia Triple Stain Immunofluorescence assay, performed on archived paraffin embedded tumor tissues.

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: 3 years

Population: There were not enough data available to analyze duration of response statistically. Only two participants had partial response and none had complete response. Of the two, only one participant had progression so duration of response could be calculated. The other participant did not progress. Duration of response is presented for the one participant.

Duration of response (DoR), defined as time from documentation of tumor response to disease progression
