Brief summary

This was a multicenter, stratified, open, randomized, comparator-controlled, parallel-group phase III study comparing treatment with Lutathera plus best supportive care (30 mg Octreotide LAR) to treatment with high dose (60 mg) Octreotide LAR in participants with metastasized or locally advanced, inoperable, somatostatin receptor positive, histologically proven midgut carcinoid tumours with progression despite LAR treatment.

Detailed description

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 Lutathera 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 tumor uptake score 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: 1. Any participants with progressive disease (confirmed by central review of CT/MRI scans) ceased the treatment/assessment period and proceeded to the long-term follow-up period for evaluation of survival and long-term safety. 2. All non-progressive participants continued treatment/assessments until the PFS primary endpoint was met (i.e. 74 evaluable and centrally confirmed disease progressions or death events). Once the Primary End-Point was reached: 1. Participants who received more than 76 weeks of treatment/assessment, stopped the study treatment (however somatostatin analogues could be received as subsequent treatment as per Investigator's discretion) but continued the long-term follow-up assessment for 5 years overall from the date of randomization of the last participant randomized. 2. The remaining randomized participants continued in the fixed 76-week treatment/assessment period unless progression occurred, then continued the long-term follow-up assessments for 5 years overall from the date of randomization of the last participant.

Interventions

In the experimental arm, 30 mg Octreotide LAR treatment was given to the participants until the end of study for symptom control purpose, unless the participant progressed or died. In the active comparator arm, 60 mg Octreotide LAR treatment was given to the participants every 4 weeks (i.m. injections) until the end of the study, unless the participant progressed or died.

Four administrations of 7.4 GBq (200 mCi) 177Lu-DOTA0-Tyr3-Octreotate administered at 8 +/- 1-week intervals, which could be extended up to 16 weeks to accommodate resolving acute toxicity.

Inclusion criteria

1. Presence of metastasized or locally advanced, inoperable (curative intent) at enrollment time, histologically proven, midgut carcinoid tumour (to be centrally confirmed). 2. Ki67 index ≤ 20% (to be centrally confirmed). 3. Patients on Octreotide LAR at a fixed dose of 20 mg or 30 mg at 3-4 weeks intervals for at least 12 weeks prior to randomization in the study. 4. Patients ≥18 years of age. 5. Patients must have progressive disease based on RECIST Criteria, Version 1.1 while receiving an uninterrupted fixed dose of Octreotide LAR (20-30 mg/3-4 weeks). Disease progression must be centrally confirmed. In order to make the assessment, two CT (or MRI) scans are required. The oldest scan must not be older than 3 years from the date of randomization. The most recent scan must not be older than 4 weeks from the date of randomization. Both scans must be obtained while the patient is receiving the same fixed dose of Octreotide LAR (20-30 mg/3-4 weeks) with the following exceptions; 1) it is acceptable if the oldest scan is obtained within 12 weeks of the patient receiving a fixed dose regimen of Octreotide LAR (20-30 mg/3-4 weeks); AND 2) it is acceptable for either scan to be obtained before or during the time a patient receiving a fixed dose of Octreotide LAR has switched to an equivalent dose of short acting Octreotide for up to 6 weeks in order to obtain an OctreoScan®, provided the patient returns to the Octreotide LAR fixed dose after the OctreoScan® has been obtained. 6. Confirmed presence of somatostatin receptors on all target lesions (for target/non-target/measurable lesions definition see §Appendix 2, Section 1 and 2, RECIST Criteria, Version 1.1) documented by CT/MRI scans, based on positive OctreoScan® imaging within 24 weeks prior to randomization in the study (to be centrally confirmed). The OctreoScan® should be one that was performed while the patient was on a fixed dose of Octreotide LAR. If a patient has had an OctreoScan® performed while Octreotide LAR treatment-naïve, the patient must have a repeat OctreoScan® performed after 3 months of Octreotide LAR treatments before entering the clinical study to prove that the index lesions or new lesions still meet the criteria for inclusion. It is acceptable to have patients temporarily switched to Octreotide s.c. (up to six weeks) in order to obtain an OctreoScan®, provided they return to the same fixed dose of Octreotide LAR prior to the scan. 7. The tumour uptake observed in each target lesion (for target/non-target/measurable lesions definition see §Appendix 2, Sections 1 and 2, RECIST Criteria, Version 1.1) using OctreoScan® must be ≥ normal liver uptake observed on planar imaging (to be centrally confirmed) (§Appendices 5 and 6). 8. Karnofsky Performance Score (KPS)\>=60. 9. Presence of at least 1 measurable site of disease. 10. \[Applicable only for France\] All patients included in the trial must be affiliated with a social security regime or be a beneficiary of the same in order to be included in the study.

MeasureTime frameDescription
Progression Free Survival (PFS)From date of randomization until date of radiographic progression or date of death from any cause, whichever comes first until Primary Analysis cutoff date reached on 24July2015, assessed up to approximately 34 monthsProgression Free Survival (PFS) was defined as the time from randomization to documented centrally assessed disease progression, as evaluated by the Independent Review Committee (IRC), or death due to any cause. If a participant had no centrally assessed progression and had not died at the time of the primary endpoint analysis, the participant was regarded as censored in the context of a time to event analysis at the date of last evaluable tumor assessment. Disease progression was determined by objective tumor response status using Response Evaluation Criteria in Solid Tumors Criteria (RECIST v1.1).

Secondary

MeasureTime frameDescription
Overall Survival (OS)From date of randomization until date of death from any cause up to final safety cut-off date reached on 18Jan2021, assessed up to approximately 100 monthsOverall Survival (OS) was defined as the time from the date of randomization to the date of death due to any cause or the date of last contact (censored observation) prior to the date of the data cut-off, and during the entire study period (i.e. the treatment period plus follow-up).
Rate of Overall Survival (OS)12 months, 24 months, 36 months, 48 months, 60 monthsSurvival estimates were collected every 12 Months up to 60 Months to compare OS between the two treatment groups.
Time to Tumour Progression (TTP)From date of randomization until date of progression or date of death from any cause, whichever comes first until Primary Analysis cutoff date reached on 24July2015, assessed up to approximately 34 monthsTime to Tumour Progression (TTP) was defined as the time from randomization to progression centrally assessed. It included patients who dropped out due to toxicity, but omitted patients who died without measured progression (censored to last follow-up date or death date).
Objective Response Rate (ORR)From date of randomization until date of progression or date of death from any cause, whichever comes first until Primary Analysis cutoff date reached on 24July2015, assessed up to approximately 34 monthsObjective Response Rate (ORR) was calculated as the proportion of patients with tumour size reduction (sum of partial responses (PR) and complete responses (CR)) according to RECIST 1.1.
Number of Participants With Adverse EventsFrom informed consent signature through study completion reached at final safety cutoff date on 18July2021, assessed up to approximately 101 MonthsThe distribution of adverse events was done via the analysis of frequencies for Adverse Event (AEs), Serious Adverse Event (SAEs) and Deaths, through the monitoring of relevant clinical and laboratory safety parameters.
Change From Baseline in the EORTC QLQ-C30 QuestionnaireInclusion (Baseline) (BL), Week 72, Week 120The Quality of Life Questionnaire C30 (QLQ-C30) was developed by the European Organization for Research and Treatment of Cancer (EORTC) to assess quality of life in cancer patients. It includes five function domains (physical, emotional, social, role, cognitive), eight symptoms (fatigue, pain, nausea/vomiting, constipation, diarrhea, insomnia, dyspnea, and appetite loss), as well as global health/quality-of-life and financial impact. Subjects respond on a four-point scale from not at all to very much for most items. Raw scores are linearly transformed so each score ranged a 0-100, where higher scores indicate worse symptoms (e.g., more severe/worsened) and lower scores indicate less symptoms (e.g., less severe/improvement).
Change From Baseline in the EORTC Quality of Life Questionnaire - Neuroendocrine Carcinoid Module (EORTC QLQ-GINET21)Inclusion (Baseline) (BL), Week 72, Week 120The Quality of Life GI Neuroendocrine Tumor survey (QLQ GINET21) contains a total of 21 items: four single-item assessments relating to muscle and/or bone pain (MBP), body image (BI), information (INF) and sexual functioning (SX), together with 17 items organized into five proposed scales: endocrine symptoms (ED; three items), GI symptoms (GI; five items), treatment-related symptoms (TR; three items), social functioning (SF) and disease-related worries (DRW; three items). The response format of the questionnaire is a four-point Likert scale. Responses are linearly transformed to a 0-100 scale using EORTC guidelines, with higher scores reflecting more severe symptoms.
Duration of Response (DoR)From date of randomization until date of progression or date of death from any cause, whichever comes first until Primary Analysis cutoff date reached on 24July2015, assessed up to approximately 34 monthsThe Duration of Response (DoR) was defined as the time from initially meeting the criteria for response (CR or PR) until the time of progression by RECIST 1.1.

Change From Baseline in the EORTC Quality of Life Questionnaire - Neuroendocrine Carcinoid Module (EORTC QLQ-GINET21)

The Quality of Life GI Neuroendocrine Tumor survey (QLQ GINET21) contains a total of 21 items: four single-item assessments relating to muscle and/or bone pain (MBP), body image (BI), information (INF) and sexual functioning (SX), together with 17 items organized into five proposed scales: endocrine symptoms (ED; three items), GI symptoms (GI; five items), treatment-related symptoms (TR; three items), social functioning (SF) and disease-related worries (DRW; three items). The response format of the questionnaire is a four-point Likert scale. Responses are linearly transformed to a 0-100 scale using EORTC guidelines, with higher scores reflecting more severe symptoms.

Time frame: Inclusion (Baseline) (BL), Week 72, Week 120

Population: Safety Analysis Set (SAF). Values at Inclusion were taken from last non-missing value prior to randomization (the only scheduled pre-randomization assessment was at the Baseline visit). Calculations at each visit included only participants with scores at the visit and Inclusion.
