简要总结
AMB-051-07 is an open-label, adaptive, dose-ranging study with long-term extension in adults with tenosynovial giant cell tumor
详细描述
AMB-051-07 is an open-label, adaptive, dose-ranging study with long-term extension which will enroll up to 48 adult subjects with tenosynovial giant cell tumor for intra-articular doses over a 24-week dosing period (Part 1) with a Part 2 open-label extension of 6 treatment and/or observational cycles of 12 weeks each followed by 12 weeks of follow-up.
