Previous SSC Communications … the approaches recommended here are primarily intended for clinical trials of factor concentrates that are being compared to other, similar preparations. … studies on individual patients for diagnostic or therapeutic purposes may not necessarily be relevant to what is discussed here.
Previous SSC Communications
AIMS: Primary PK and PopPK estimates of factor concentrates: – Reporting – Interpretation – Assessment in clinical practice – Study design for “real world/PM” PopPK assessment
AIMS: Secondary PK and PopPK estimation: – During registration phase – To compare different molecules – Choice of time points – ….
PROCESS How (and whether) to best involve: – Pharmaceutical companies PK/PopPK experts – FDA / EMA PK/PopPK experts – Authors of PK/PopPK published papers – Patient representatives
PROGRESS 2 conference calls 1 panel survey Bi-monthly conference calls Review of the existing literature Review of regulators guidance Draft recommendations on primary goals
