Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This was a multicenter, stratified, open, randomized, comparator-controlled, parallel-group phase III study comparing treatment with Lutetium\[177Lu\] Oxodotreotide Injection to high dose (60 mg) Octreotide LAR in patients with unresectable or metastatic, progressive, well differentiated (G1 and G2), somatostatin receptor positive gastroenteropancreatic neuroendocrine tumours.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

After the screening period, participants who signed the ICF and were eligible for the study in accordance with the entry criteria were randomly assigned to treatment either Lutetium\[177Lu\] Oxodotreotide Injection or Octreotide LAR. Participant randomization was performed according to a centralized permuted block randomization scheme with a balanced ratio (1:1) between the 2 treatment groups, stratified by primary site of tumor (pancreatic or non-pancreatic), NET pathological grading (G1 or G2) and by the length of time that a participant was on a constant dose of Octreotide (=\< 6 versus \> 6 months). Objective tumor assessment in both groups was performed every 12+/-1 weeks from the randomization date according to RECIST Criteria until progression was centrally confirmed: any participants with progressive disease ceased the treatment/assessment period and proceeded to the long-term follow-up period for evaluation of survival and long-term safety.

Study Groups

Lutetium[177Lu] Oxodotreotide Injection

Treatment consisted of a cumulative administered radioactivity of 29.6 Giga Becquerel (GBq) (800 mCi) Lutetium\[177Lu\] Oxodotreotide Injection: Four administrations of 7.4 GBq (200 mCi).

Concomitant amino acids were given with each administration for kidney protection.

Lutetium\[177Lu\] Oxodotreotide Injection was administered at 8 +/- 1-week intervals, which could be extended up to 16 weeks to accommodate resolving acute toxicity.

In case participants experienced clinical symptoms (i.e. diarrhoea and flushing) associated with their carcinoid tumours, Octreotide s.c. rescue injections were allowed.

Group Type EXPERIMENTAL

Octreotide LAR

60 mg Octreotide LAR treatment every 4 weeks (i.m. injections) until the end of the study, unless the participant progressed or died.

In case participants experienced clinical symptoms (i.e. diarrhoea and flushing) associated with their carcinoid tumours, s.c. Octreotide rescue injections were allowed.

5. Presence of disease progression prior to randomization (time point of disease progression limited to 1 year prior to randomization and no other antitumor therapy received after progression).
6. Presence of at least 1 measurable site of disease (based on RECIST 1.1).
7. All target lesions (based on RECIST 1.1) at baseline must be confirmed as somatostatin receptor positive by 68Ga-Dotatate PET/CT .
8. ECOG score of 0 or 1.
9. Subjects of childbearing potential voluntarily use an effective method of contraception, such as condoms, oral or injectable contraceptives, IUDs, etc., during treatment and within 4 months (men) or 7 months (women) of the last use of the trial drug.
