Background: Octreotide long-acting release (LAR) is a common drug used for acromegaly that aims to normalize serum growth hormone (GH) and insulin-like growth factor-1 (IGF-1). However, only a few studies have evaluated its efficacy and safety in Chinese patients. This retrospective study aimed to assess its efficacy and safety in a cohort of Chinese patients with acromegaly.
Methods: A total of 163 patients with acromegaly, who received continuous and regular octreotide LAR treatment at least three times at Peking Union Medical College Hospital between 2010 and 2020, were enrolled. Clinical characteristics, acromegaly activity, and other laboratory tests before and after treatment were collected for analysis.
Results: The study enrolled 163 patients, including 71 men (43.6%) with a mean age of 40.94±13.00 years. After octreotide LAR treatment, 34.4% of the patients achieved GH control (<2.5 ng/mL), while IGF-1 levels were normalized in 23.3% of the patients. Also, fasting GH levels were downregulated from 4.95 ng/mL [interquartile range (IQR) 2.225, 10.325 ng/mL] at baseline to 3.2 ng/mL (IQR 1.5, 6.6 ng/mL) (P<0.001), and IGF-1/upper limit of the normal (ULN) declined from 1.89 (IQR 1.22, 2.40) to 1.41 (IQR 0.97, 1.89) (P<0.001). In addition, 65 patients experienced moderate adverse events. During the follow-up, none of the patients discontinued octreotide LAR. Further logistic regression showed that comorbidity [odds ratio (OR), 3.19; 95% confidence interval (CI): 1.20-9.27; P=0.025] and previous surgery only (OR, 0.21; 95% CI: 0.08-0.58; P=0.003) were two risk factors for the development of adverse events.
Conclusions: Our findings revealed that octreotide LAR treatment is effective in normalizing GH and IGF-1 levels in Chinese patients with acromegaly. In addition, adverse events related to octreotide LAR use were moderate and well tolerated by the patients.

Regulatory authorities typically require bioequivalence to be demonstrated by comparing pharmacokinetic parameters like area under the plasma concentration-time curve (AUC) and maximum plasma concentration (C). Because in certain cases, AUC and C alone may not be adequate to identify formulation differences in early and/or late segments of the dosing interval, partial AUCs (pAUCs) have been proposed as additional metrics to evaluate bioequivalence. Even though cut-off points for pAUCs are usually decided based on clinical relevance, the identification of the correct cut-off range remains elusive in many other cases and tends to contribute to increased pAUC estimate variabilities.

With the current therapeutic modalities available to endocrinologists, control of GH and IGF-I is now possible in almost all patients with acromegaly with multi-modality therapy. Despite biochemical control of GH and IGF-I, patients with acromegaly continue to experience impaired quality of life. Although there are likely multiple factors contributing to this dissatisfaction with current medical therapies, in particular the widely utilised injectable long-acting somatostatin receptor ligands (iSRL), is a contributor.

Somatostatin and its analogs have been for years a mainstay treatment for a variety of hypersecretory conditions and neoplasms of the endocrine system. This chapter summarizes their pharmacological properties, their indication in the context of acromegaly, and the best way to handle this class of drugs for the treatment of the patient with acromegaly.

Article Synopsis
- Acromegaly, a condition caused by excessive growth hormone and IGF-1, negatively affects patients' quality of life and is conventionally treated with healthcare-administered therapies, while CAM2029 offers a self-administered option with better convenience and storage.
- A 24-week phase 3 trial involving 72 patients assessed the effectiveness of CAM2029 compared to placebo, focusing on the control of IGF-1 levels and GH.
- Results at Week 22/24 showed that CAM2029 significantly outperformed placebo in controlling IGF-1 and GH levels, leading to improved symptoms, quality of life, and patient satisfaction.
