In more good news, today the Pharmaceutical Benefits Scheme (PBS) in Australia added venetoclax to its listings for the retreatment of CLL/SLL in those whose disease relapses/progresses after an initial venetoclax-based therapy has controlled it.
The PBS Listing states:
"Chronic lymphocytic leukaemia (CLL)
Treatment Phase: Dose titration occurring at the start of treatment for relapsed/refractory disease
Clinical criteria:
The condition must have relapsed or be refractory to at least one prior therapy,
AND
The treatment must be the sole PBS-subsidised therapy for this condition,
AND
The treatment must only be prescribed for a patient with active disease in accordance with the International Workshop on CLL (iwCLL) guidance (latest version) in relation to when to prescribe drug treatment for this condition.
Treatment criteria:
Patient must not be undergoing retreatment with this drug where prior, active treatment of CLL/SLL with this same drug was unable to prevent disease progression."

This letter to the ASH publication Blood Advance in August 2022 ("Venetoclax retreatment of patients with chronic lymphocytic leukemia after a previous venetoclax-based regimen") provides some more information about the rationale behind the use of venetoclax as a retreatment for CLL/SLL.
