Study Overview

A Trial to Assess Efficacy, Safety, Pharmacokinetics of Octreotide Subcutaneous Injection in Patients With Gastroentero-pancreatic Neuroendocrine Tumor (GEP-NET)

The purpose of this study is to compare the effectiveness, safety, pharmacokinetics (PK) of SYHX2008 vs Octreotide Microspheres (Sandostatin LAR@) in patients with advanced, well-differentiated GEP-NET.

This is a Phase II, open-label randomized study to assess the PK, efficacy, and safety of SYHX2008 in adult patients with well-differentiated GEP-NET. Patients will be randomized to SYHX2008 cohort or Octreotide Microspheres cohort (Sandostatin LAR@).

  • Gastrointestinal Neuroendocrine Pancreatic Tumor
  • DRUG: SYHX2008 injection
  • DRUG: Sandostatin LAR@
  • SYHX2008-004

Interventional Model:
Parallel

Masking:
None

Arms and Interventions

Participant Group/ArmIntervention/Treatment
EXPERIMENTAL: SYHX2008 injection

DRUG: SYHX2008 injection

  • The patients will accept SYHX2008 injection by subcutaneous administration every cycle.

Primary Outcome MeasuresMeasure DescriptionTime Frame
Progression-free survival (PFS) as assessed by a Blinded Independent Review Committee (BIRC)PFS is defined as time from the date of randomization to the date of the first documented disease progression as per RECIST 1.1 or death due to any cause (whichever occurs first)Up to 1 years following the last patient enrolled
Secondary Outcome MeasuresMeasure DescriptionTime Frame
Overall survival (OS)The time from the date of randomization to the date of death due to any causeUp to 1 years following the last patient enrolled
PFS as assessed by local InvestigatorsPFS as assessed by local InvestigatorsUp to 1 years following the last patient enrolled
Overall response rate(ORR)The proportion of patients with best overall response of complete response (CR) or partial response (PR), according to RECIST 1.1Up to 1 years following the last patient enrolled
Disease control rate (DCR)The proportion of patients with a best overall response of CR, PR or stable disease (SD), according to RECIST 1.1Up to 1 years following the last patient enrolled
Duration of response (DOR)The time from the date of the first documented response of CR or PR to the date of the first documented progression or death due to underlying cancer, according to RECIST 1.1Up to 1 years following the last patient enrolled
Time to Tomor Progression(TTP)TTP is defined as time from the date of randomization to the date of the first documented disease progression as per RECIST 1.1Up to 1 years following the last patient enrolled
Control of cancer-like symptoms (diarrhea and/or flushing)Assess the total occurrences of diarrhea and/or flushing ( cancer-like symptoms): Evaluate every 8 weeks (±3 days) for the first 12 months following the initial dosage, then every 12 weeks (±7 days). This assessment is based on the total instances of diarrhea and/or flushing episodes within the 7 days preceding the assessment visit.Up to 1 years following the last patient enrolled
Incidence of treatment-emergent adverse eventsIncidence of treatment-emergent adverse eventsUp to 1 years following the last patient enrolled
