SST and neoplasm: TBR-760 (previously BIM-23A760), a chimeric DA-SST analogue compound with high affinity both for D2R and SSTR2, has demonstrated significant suppression both of GH and PRL secretion from cultured primary human acromegalic tumor cells, with both potency and efficacy significantly greater than pure DA and SST analogues, either alone or in combination (23, 29, 30).
