A Single-arm, Phase II Clinical Trial of ASPIRin to prEvent Venous Thromboembolism in Patients With Advanced Germ Cell Tumors Receiving Chemotherapy

Обзор

The purpose of this study is to the 6-month Venous Thromboembolism (VTE)-free rate in participants with advanced germ cell cancer at high risk of VTE who are receiving standard of care cisplatin-based chemotherapy and low-dose acetylsalicylic acid (ASA) and compare to relevant historical controls

Подробное описание

This is a single-arm, two-stage, Phase II study designed to evaluate the 6-month VTE-free rate in participants with advanced germ cell cancer at high risk of VTE who are receiving standard of care cisplatin-based chemotherapy and low-dose ASA as compared to relevant historical controls. Stage 1 will consist of 13 participants. If at least 9 of those 13 do not experience a VTE event during the first 26 weeks on the ASA, Stage 2 will be activated. Stage 2 will enroll an additional 18 participants for a total of 31. Participants will provide their own supply of ASA. Participants will self-administer a fixed dose of ASA (81 mg) by mouth daily for 26 weeks. Participants who experience the primary endpoint of VTE will stop ASA and start standard of care anticoagulation at the direction of the treating investigator. This study will initially open as a single center study at Atrium Health Wake Forest Baptist Comprehensive Cancer Center (AHWFBCCC) and additional investigational site(s) may be added following activation at the lead site.

Stage IIIB - any pT/TX, N1-3, M0, S2 or any pT/TX, any N, M1a, S2 v. Stage IIIC - any pT/TX, N1-3, M0, S3 or any pT/TX, any N, M1a, S3 or any pT/TX, any N, M1b, any S Serum marker (S category) S criteria SX Marker studies not available or not performed S0 Marker study levels within normal limits S1 LDH < 1.5 x normal and hCG < 5000 IU/L and AFP <1000 ng/mL S2 LDH 1.5 to 10 x normal or hCG 5000 to 50,000 IU/L or AFP 1000 to 10,000 ng/mL S3 LDH >10 x normal or hCG >50,000 IU/L or AFP >10,000 ng/mL

b. Intermediate or poor risk by IGCCCG criteria i. Intermediate risk - testis/retroperitoneal primary and no non pulmonary visceral metastases plus at least one of the following markers: AFP > 1,000 ng/mL to ≤ 10,000 ng/mL, beta-hCG > 5,000 IU/L and ≤ 50,000 IU/L, LDH >1.5 x normal and ≤ 10 x normal ii. Poor risk - mediastinal primary or non-pulmonary visceral metastases plus at least one of the following markers: AFP > 10,000 ng/mL, beta- hCG > 50,000 IU/L, LDH > 10 x normal c. Khorana score of 2 or higher i. +1 point for testicular/germ cell cancer (All patients will receive +1 for their testicular/germ cell cancer diagnosis. Thus, a patient with any other Khorana characteristic \[ii-v\] will meet this inclusion criteria.) ii. +1 point for platelet ≥350 x 10\^9/L iii. +1 point for hemoglobin <10 g/dL iv. +1 point for leukocyte count >11 x 10\^9/L v. +1 point for BMI >35 kg/m\^2

Note: ASA should be initiated no later than 2 weeks after initiation of standard front-line chemotherapy.
• As determined by the enrolling investigator, ability of the participant to understand and comply with study procedures for the entire length of the study
• Ability to swallow oral medications

Критерии исключения
