A randomized trial of avatrombopag, an investigational thrombopoietin-receptor agonist, in persistent and chronic immune thrombocytopenia.

Stimulation of platelet production by thrombopoietin-receptor agonists (TPO-RAs) is an effective second-line treatment in immune thrombocytopenia (ITP). This 28-day phase 2 study assigned subjects with ITP of ≥3 months to once-daily oral avatrombopag (2.5, 5, 10, or 20 mg), an investigational nonpeptide TPO-RA active in humans, or placebo; subjects completing randomized treatment could enroll in a 24-week extension study.

Phase III, double-blind, controlled trial of atamestane plus toremifene compared with letrozole in postmenopausal women with advanced receptor-positive breast cancer.

Purpose: To compare time to progression (TTP) with a steroidal aromatase inhibitor (AI) atamestane (ATA) combined with toremifene (TOR; complete estrogen blockade) versus letrozole (LET) in receptor-positive advanced breast cancer (ABC).

Patients And Methods: Eligibility included postmenopausal receptor-positive ABC and adjuvant hormonal therapy completed more than 12 months prior to study entry. Participants received daily ATA 500 mg with TOR 60 mg (ATA + TOR), or letrozole 2.
