Abstract
Acromegaly treatment has greatly evolved in recent decades, but there are still patients whose acromegaly is not controlled with currently available treatments, and there is a need to improve the treatment burden. Fortunately, there are new treatments under development that may increase treatment efficacy and convenience.

Abstract
OBJECTIVE After surgery, when somatostatin analogs (SAs) do not normalise IGF-I, pegvisomant (PEG) is indicated. Our aim was to define the medical reasons for the treatment of patients with PEG as monotherapy (M) or combined with SA, either as primary bitherapy, PB (PEG is secondarily introduced after SA) or as secondary bitherapy, SB (SAs secondarily introduced after PEG). METHODS We retrospectively analysed French data from ACROSTUDY. RESULTS 167, 88 and 57 patients were treated with M, PB or SB, respectively, during a median time of 80, 42 and 70 months. The median PEG dose was respectively 15, 10 and 20 mg. Before PEG, the mean IGF-I level did not differ between M and PB but the proportion of patients with suprasellar tumour extension was higher in PB group (67.5% vs. 44.4%, P = 0.022). SB regimen was used preferentially in patients with tumour increase and IGF-I level difficult to normalise under PEG. In both secondary regimens, the decrease of the frequency of PEG's injections, compared to monotherapy was confirmed. However, the mean weekly dose of PEG between M and PB remained the same. CONCLUSIONS The medical rationale for continuing SAs rather than switching to PEG alone in patients who do not normalise IGF-I under SAs was a tumour concern with suprasellar extension and tumour shrinkage under SA. A potential explanation for introducing SA in association with PEG appears to be a tumour enlargement and difficulties to normalise IGF-I levels under PEG given alone. In both regimens, the prospect of lowering PEG injection frequency favoured the choice.

Abstract
BACKGROUND The competitive GH receptor antagonist pegvisomant is reported to normalise IGF-1 levels in up to 97 % of acromegalic patients at a maximum dosage of 40 mg/d. Description of Case: We present an acromegalic patient resistant to the recommended maximum GH receptor antagonist dosage. The 60-year-old male patient presenting with typical clinical signs of acromegaly has underwent multiple transsphenoidal surgeries and pituitary irradiation, while currently available pharmacological therapies for acromegaly have been exhausted. RESULTS Biochemical control of the disease could only be achieved until uptitration of pegvisomant to 60 mg/d which was tolerated well. CONCLUSIONS The current treatment algorithm for acromegaly should be modified to treat cases of persistent and uncontrolled disease.
