Quick Navigation

Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

This is a phase 1 single dose, open-label, randomized, two-period, two-sequence, crossover study of ALG-055009 conducted in 1 cohort of healthy volunteers. The primary purpose of this study is to compare the single-dose pharmacokinetics of the 0.7 mg dose level of 2 types of soft gelatin capsule formulations of ALG-055009, Formulation 1 and Formulation 2, in approximately 8 healthy volunteers.

Post menopausal: A postmenopausal state is defined as no menses for at least 12 months without an alternative medical explanation . A high follicle-stimulating hormone (FSH) level in the postmenopausal range of \>40 IU may be used to confirm a postmenopausal state in women not using hormonal contraception or hormonal replacement therapy (HRT). 2.
