NCT ID: NCT02540356

Last Updated: 2021-01-12

Results Overview

DLT is defined as any drug related treatment-emergent adverse event that occurs during the 28-day period after the first dose of Imalumab and that meets any of these criteria: - Any ≥ grade 3 non-hematologic toxicity assessed by the investigator as related to study drug (except: single lab value out of normal range not necessarily translating or considered a feature of clinical diagnosis requiring an intervention per investigator's interpretation and resolves to ≤ Grade 2 with adequate measure in 7 days; Transient grade 3 elevations of hepatic transaminases in the absence of simultaneous increase in serum bilirubin; Alopecia) - Any toxicity resulted in dose delay for ≥14 days - Any grade 4 hematologic toxicity (except lymphopenia) - Grade 3 febrile neutropenia - Grade 3 thrombocytopenia associated with bleeding - Any life-threatening complication/abnormality not covered in the NCICTCAE v4.03

PRIMARY outcome

Timeframe: 4 weeks

Population: Study was terminated early with only one participant dosed. No statistical analysis was performed on this outcome measure. Additionally, due to concerns that the participant would be at risk of being re-identified, study results are not posted.

PuFS is defined as the time from the last dose of Imalumab to the first therapeutic paracentesis after that, or death, whichever occurs first. Puncture-free interval at baseline is calculated as the time between the last 2 therapeutic paracenteses immediately before the first dose of Imalubmab.

Timeframe: 4 weeks

Population: Study was terminated early with only one participant dosed. No statistical analysis was performed on this outcome measure. Additionally, due to concerns that the participant would be at risk of being re-identified, study results are not posted.

Time to first paracentesis post-treatment is calculated as the time between the last dose of Imalumab to subsequent first therapeutic paracentesis.

SECONDARY outcome

Timeframe: Up to 4 weeks

Population: Study was terminated early with only one participant dosed. No statistical analysis was performed on this outcome measure. Additionally, due to concerns that the participant would be at risk of being re-identified, study results are not posted.

The volume of ascites from the last dose of Imalumab to the first post-treatment paracentesis per unit time will be compared to the volume of the last pre-treatment paracentesis per unit time. At each paracentesis, the volume of fluid that can be removed safely (measured by ultrasound-guided paracentesis) to achieve close to dryness should be withdrawn, measured, and documented.
