A Study of Adavosertib as Treatment for Uterine Serous Carcinoma (ADAGIO)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT04590248
Recruitment Status : Completed
First Posted : October 19, 2020

Information provided by (Responsible Party):

Brief Summary:
This Phase 2b study aims to evaluate the efficacy and safety of adavosertib, an inhibitor of the tyrosine kinase WEE1, in subjects with recurrent or persistent uterine serous carcinoma (USC) who have previously received at least 1 prior platinum-based chemotherapy regimen for the management of USC.

Condition or disease Intervention/treatment Phase
Uterine Serous Carcinoma Drug: Adavosertib Phase 2

Detailed Description:
This Phase 2b, open-label, single-arm, multi-center study will assess the efficacy and safety of adavosertib in eligible subjects with histologically confirmed recurrent or persistent USC, evidence of measurable disease as per Response Evaluation Criteria in Solid Tumors.(RECIST) v1.1, and who have received at least 1 prior platinum-based chemotherapy regimen for the management of USC. Subjects with carcinosarcomas are not eligible.

Other Name: AZD1775

Primary Outcome Measures :
  1. Objective response rate (ORR) [ Time Frame: From baseline to approximately 24 months ]
    The percentage of subjects with measurable disease at baseline who have a confirmed complete response (CR) or partial response (PR), as determined by Blinded Independent Central Review (BICR) per RECIST v1.1

Secondary Outcome Measures :
  1. Duration of response (DoR) [ Time Frame: From baseline to approximately 24 months ]
    The time from the date of first documented response until date of documented progression per RECIST v1.1 as assessed by BICR, or death in the absence of disease progression

  2. Depth of response [ Time Frame: From baseline to approximately 24 months ]
    Absolute change and percentage change from baseline will be based on RECIST v1.1 target lesions measurements

  3. Progression free survival (PFS) [ Time Frame: From baseline to approximately 24 months ]
    The time from first dose until the date of objective disease progression or death (by any cause in the absence of progression), derived using RECIST v1.1 assessments based on BICR data

  4. PFS6 [ Time Frame: From baseline up to 6 months ]
    The proportion of subjects alive and progression free at 6 months by Kaplan-Meier estimate

  5. Overall survival (OS) [ Time Frame: From baseline to approximately 24 months ]
    The time from date of first dose until the date of death due to any cause

  6. Disease control rate (DCR) [ Time Frame: From baseline to approximately 24 months ]
    The percentage of subjects who have a best response of confirmed CR or PR or who have stable disease for at least 5 weeks after start of treatment, based on BICR data

  7. Lowest concentration (Ctrough) of adavosertib [ Time Frame: Pre-dose (60 minutes prior to dosing) on Day 5 of Cycles 1 and 2 (each cycle is 21 days) ]
    Lowest plasma concentration of adavosertib before next dose

  8. Maximum concentration (Cmax) of adavosertib [ Time Frame: 2 hours post-dose on Day 5 of Cycles 1 and 2 (each cycle is 21 days) ]
    Maximum plasma concentration of adavosertib after oral dosing

  9. Number of subjects with adverse events (AE) and serious AEs [ Time Frame: From baseline to post-treatment follow-up (30 days after last dose) ]
    Assessment of AEs, vital signs, clinical laboratory values, electrocardiogram findings, and AEs leading to dose interruptions, dose reductions, and dose discontinuations
