Introduction: Results of the first European real-world evidence from retrospective cohort of ACRONIS study previously confirmed the efficacy and tolerability of LA-PAS in heavily pre-treated, uncontrolled acromegaly patients. Here, we report results of the second interim analysis reflecting the prospective cohort.

Methods: Patients who were treated with LA-PAS for ≥6 months were included in this analysis. The primary objective was to document treatment efficacy, defined by the proportion of patients who achieved IGF-1 level normalization <1 upper limit of normal (ULN) and GH <1 µg/l at 6 months of LA-PAS treatment. Key secondary objectives were changes from baseline in standardized IGF-1 and GH levels, proportion of patients with IGF-1 normalization and GH normalization over time, overall safety and tolerability of LA-PAS.

Results: On 13 Sep 2019, 112 of 200 enrolled patients completed 6 months LA-PAS treatment. Among these, 94 and 109 were included in efficacy and safety analysis, respectively. The mean age of the patients was 50.1 years; 51.1% were male. Median time since diagnosis was 66.5 months; 73.4% had previous surgery and 19.1% had radiotherapy; 98.9% had taken prior medication, mainly first-generation SSAs (58.5% octreotide, 61.7% lanreotide), growth hormone receptor antagonists (38.3%) or dopamine agonists (37.2%) as mono- or combination therapy. In the safety analysis set, 22.0% and 37.6% of patients were diabetic or pre-diabetic prior to LA-PAS prescription, respectively. IGF-1 normalization <1 ULN and random GH <1 µg/l was achieved in 31.9% (95% CI, 21.4–43.9) of patients and IGF-1 normalization <1 ULN and random GH <2.5 µg/l in 44.4% (95% CI, 32.7–56.6) at 6 months. Median (95% CI) percentage reductions from baseline in IGF-1 and GH were 34.3% (43.0–27.6) and 66.8% (73.4–52.9) at 6 months, respectively. IGF-1 normalization (<1 µg/l and <1.3 µg/l) was achieved in 51.8% (40.6–62.9) and 72.3% (61.4–81.6) at 6 months. After median exposure of 22.1 months (range 5.9–29.8), 68.8% remained on starting dose, 22% were up-titrated once, 4.6% were down-titrated once and 4.6% required multiple dose changes. The most common adverse events (AEs in >10%) reported were hyperglycemia (21.1%), diagnosed diabetes mellitus (12.8%) and diarrhea (10.1%). One patient reported permanent discontinuation of LA-PAS due to Grade 2 hyperglycemia.

Conclusion: Findings from this prospective ACRONIS dataset confirm the efficacy of LA-PAS in previously uncontrolled acromegaly patients and are in agreement with those reported in a previous randomized trial (Gadelha, et al. Lancet Diabetes Endocrinol. 2014). The safety of LA-PAS was consistent with its known profile.
