Brief Summary

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

Outcome Measures

Primary Outcomes (1)

  • Venous thromboembolism (VTE)-free

    A binary variable indicating whether the participant had zero VTE events within 26 weeks of initiation of standard chemotherapy. VTE events include objectively confirmed symptomatic or asymptomatic proximal deep-vein thrombosis in a lower limb, symptomatic deep-vein thrombosis in an upper limb or distal deep-vein thrombosis in a lower limb, symptomatic or incidental pulmonary embolism, symptomatic or incidental central catheter related thrombosis, or death from venous thromboembolism.

    26 weeks after initiation of standard chemotherapy

Secondary Outcomes (4)

  • Major Bleeding Event

    26 weeks after initiation of standard chemotherapy

  • Clinically Relevant Non-Major Bleeding

    26 weeks after initiation of standard chemotherapy

  • Relapse-Free Survival (RFS)

    2 years after initiation of standard chemotherapy

  • Overall Survival (OS)

    2 years after initiation of standard chemotherapy

Other Outcomes (1)

  • Febrile Neutropenia Event

    26 weeks after initiation of standard chemotherapy

Study Arms (1)

Low-dose aspirin (acetylsalicylic acid [ASA])

EXPERIMENTAL

ASA has been shown to reduce risk of VTE. It will be self-administered, a fixed dose of ASA (81 mg) by mouth daily for 26 weeks.

Drug: Low-dose ASA

Interventions

81 mg by mouth daily for 26 weeks

Also known as: aspirin
Low-dose aspirin (acetylsalicylic acid [ASA])

  • Performance Status (PS) of ECOG 0-2 at the time of enrollment
  • At least one of the following "high risk" of VTE features:
  • a. Stage IIC or III or higher per AJCC 8th edition criteria i. Stage IIC - any pT/TX, N3, M0, S0-1 ii. Stage III - any pT/TX, any N, M1, SX iii. Stage IIIA - any pT/TX, any N, M1a, S0-1 iv. 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
  • Planning or recently started 3-4 cycles of standard of care front-line cisplatin-based chemotherapy (bleomycin, etoposide, and platinum \[BEP\], etoposide and cisplatin \[EP\], or etoposide, ifosfamide, and cisplatin \[VIP\]). 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

You may not qualify if:

  • Receiving chemotherapy in adjuvant setting
  • Prior VTE/PE
  • Currently taking anticoagulation or antiplatelet therapy. Non-steroidal anti-inflammatory drug (NSAID) use for pain is allowed
  • Prior indication for anticoagulation or anticoagulation contraindicated (e.g., active bleed or risk of bleeding, such as history of gastrointestinal ulcers)
  • Allergy to ASA
