简要总结
To evaluate the efficacy of romiplostim for the treatment of CIT in patients receiving chemotherapy for the treatment of lymphomas measured by the ability to administer on-time, full-dose chemotherapy.
详细描述
This is a phase 3, randomized, placebo-controlled, multicenter, international study for the treatment of CIT in adult subjects receiving chemotherapy for the treatment of lymphomas, defined by 2 platelet counts < 30 x 10^9/L at least 7 days apart. The study will consist of a screening period of up to 4 weeks, a 16-week treatment period, an end-of-treatment (EOT) visit, and long-term follow-up.

入选标准
- •101 Subject has provided informed consent/assent prior to initiation of any study-specific activities/procedures or subject's legally acceptable representative has provided informed consent prior to any study-specific activities/procedures being initiated when the subject has any kind of condition that, in the opinion of the investigator, may compromise the ability of the subject to give written informed consent.
- •102 Males or females ≥ 18 years of age at signing of the informed consent.
- •103 Documented active lymphoma.
- •104 Receiving cancer treatment with 14-, 21-, or 28-day cycles, using medication such as alkylating agents, anthracyclines, carboplatin, cisplatin, nucleoside analogs, or any other chemotherapy agents with thrombocytopenia as a warning or adverse reaction.
- •105 Subjects must have 2 platelet counts < 30 x 109/L at least 7 days apart as a result of the chemotherapy administered in the cycle immediately preceding study entry, and no platelet count ≥ 50 x 109/L during 3-week period prior to enrollment despite dose delay or dose modification of chemotherapy regimen. The first platelet count < 30 x 109/L may be collected from local lab platelet count and must be confirmed within the 28-day screening period.
- •106 Subjects must not have received chemotherapy within 14 days prior to first dose of investigational product.
- •107 Subjects must have at least 4 additional planned cycles of chemotherapy at study enrollment.
- •108 Subjects must be able to receive the same chemotherapy regimen (when possible, same schedule and same agents) for at least 2 additional cycles per investigator judgement.
- •109 Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
