Abstract

Bryostatin 1, a macrocyclic lactoneisolated from the marine bryozoan Bugula neritina,is a protein kinase C (PKC) modulator which has shown bothpreclinical and clinical activity inlymphoid malignancies. We conducted aphase II trial of bryostatin 1 administeredat a dose of 120 μg/m2 by 72-hcontinuous infusion every 2 weeks inpatients with relapsed multiple myeloma. Treatment was well tolerated with myalgiasconstituting the primaray toxicity. Therewere no responses in nine evaluablepatients. The preclinical anti-lymphoidactivity is strong enough to supportfurther exploration of bryostatin 1 indifferent schedules and in combinationtherapy for multiple myeloma.
