Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Study arms

  • Experimental
    Fostamatinib

    Subjects who at any time during the C-935788-057 study achieved a hemoglobin response will continue at their dose and regimen from the Week 22 visit in the C-935788-057 study. All other subjects who enter the extension study will initially receive fostamatinib 100 mg PO bid. Starting at Week 4, the initial fostamatinib dose of 100 mg PO bid will be increased to fostamatinib 150 mg PO bid if subjects have adequately tolerated the study drug, based on the Investigator's judgment.

    Drug: Fostamatinib disodium

Interventions

  • Fostamatinib is supplied in two (2) dosage strengths: 100 mg and 150 mg.

    Also known as: R935788, Fostamatinib

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Mar 17, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
