bryostatin 1 : A member of the class of bryostatins that is (17E)-2-oxooxacyclohexacos-17-ene which is substituted by hydroxy groups at positions 4, 10, and 20; an acetoxy group at position 8; methyl groups at positions 9, 9, 18, and 19; 2-methoxy-2-oxoethylidene groups at positions 14 and 24; an (E,E)-octa-2,4-dienoyloxy group at position 21; and with oxygen bridges linking positions 6 to 10, 12 to 16, and 20 to 24. It is one of the most abundant member of the class of bryostatins.

Dosage Studied

Bryostatin 1 (Bryo) has been shown to induce biphasic dose-response curves for down-regulating protein kinase Cdelta (PKCdelta) and for protecting PKCdelta from down-regulation induced by phorbol 12-myristate 13-acetate (PMA) There is a dose- response relationship with 100 micrograms/kg having a greater effect on survival than 40 microgramS/kg. Bryostatin1 was markedly more potent than PMA for translocating PKC de.

Observed Response Rate.

"All patients had measurable disease and were assessed after 2 cycles of chemotherapy by medical photograph, plain x-ray, CT, MRI or other imaging scans of at least 2.0 cm or greater with conventional techniques or 1.0 cm or greater with spiral CT. Patients were evaluated by RECIST criteria. All measurable lesions, up to 10 target lesions were recorded and measured at baseline across the longest diameter (LD). All other non-target lesions were documented as present or absent. Complete Response (CR) was defined as complete disappearance of the tumor, partial response (PR) was defined as at least a 30% decrease of the sum of the LD of the target lesions, using the baseline sum LD as the reference~The observed response rate was defined as the percentage of evaluable patients whose best response is a CR or PR with associated 95% confidence interval." (NCT00006389)
Timeframe: Best response recorded from the start of treatment until disease progression/recurrence. Assessed every 2 cycles.

Efficacy: Change From Baseline in Severe Impairment Battery (SIB) in the Full Analysis Set (FAS)

The primary statistical objective for efficacy was to estimate the effect of bryostatin on the mean change in the total SIB score after 12 weeks of treatment, assessed at Week 13 (day 91). Efficacy analyses were conducted according to randomized groups. The SIB is used to assess cognition in subjects with moderate and severe AD. It is divided into nine subscales that include attention, language, orientation, memory, praxis, visuospatial ability, construction, social skills, orienting head to name. Non-verbal responses are allowed, thus decreasing the need for language output. Forty questions are included with a point score range of 0-100. Lower scores indicate greater cognitive impairment.
