Phase II Study of Everolimus Combined With Octreotide LAR to Treat Advanced GI NET (EVERLAR)

The underlying hypothesis of the synergistic activity of octreotide and everolimus is based on the combination of a) a direct action of everolimus over mTOR (mammalian target of rapamycin), and b) the inhibitory effect of octreotide on the IGF-I (insulin like growth factor 1) system preventing the activation of the mTOR system by this factor. Both types of inhibition would completely cancel this signal transduction pathway, which is so important in neuroendocrine tumours.

Furthermore, the biological study proposed in this protocol will allow for better establishing the relationship between the activation of the IGFR-PI3K-mTOR signal transduction pathway (i.e., the mTOR pathway stimulated by IGFR) and treatment response; this information is relevant since the IGFR-PI3K-mTOR activation status could be a response prediction factor.

This study will provide significant additional information about the efficacy of the combination treatment of everolimus with octreotide LAR® in non-functioning GI NET.

Primary Outcome Measures:
  • Percentage of patients with progression-free survival (PFS) [ Time Frame: After 12 month of study treatment ]
    Rate of patients

Secondary Outcome Measures:
  • Number of patients positive for insulin like growth factor 1 receptor (IGF1R) and ribosomal kinase S6 (S6K) phosphorylation. [ Time Frame: At baseline ]
    Activation status of mTOR pathway.

  • Rate of patients with objective responses [ Time Frame: Each three cycles ]
    Includes duration of response

  • Median and average of time for Overall survival [ Time Frame: At the end of the study ]
  • Rate of patients with an early decrease of chromogranin A (CgA) levels [ Time Frame: Each cycle ]
    CgA levels will be measured when increased at baseline and up to its normalization.

  • Percentage of patients with Adverse Events [ Time Frame: Each cycle ]

Estimated Enrollment: 40

Estimated Study Completion Date: April 2018
Primary Completion Date: April 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Everolimus + Octreotide LAR treatment Drug: Everolimus
Everolimus 10mg/day
Other Name: Afinitor
Drug: octreotide LAR
30 mg each 28 days
Other Name: Sandostatin LAR

Detailed Description:
Everolimus has been developed following two administration regimens: weekly and daily. Phase I pharmacodynamic studies recommend doses of 50 mg weekly and 10 mg/daily, based on its toxicity and inhibitory effect of the mTOR pathway in tumours; although the inhibition of this pathway has been demonstrated, the knowledge of response prediction factors has not been developed, in part due to the very low responses found in the population in phase I studies. These factors can be better outlined in a phase II study, where patients who have received fewer previous treatments can respond better, and where the profile of responders and non-responders can be identified more easily.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Diagnosis of non-operable or metastatic non-functioning, well differentiated advanced GI NET, confirmed by cytology or histology. In case of liver metastasis, neuroendocrine tumours of unknown origin are accepted.
  • Confirmation of diagnosis of neuroendocrine carcinoma of low to intermediate histology grade
  • Radiologically documented disease progression within 12 months prior to inclusion in the study. If the patient received anticancer treatment within the past 12 months, disease progression must be documented by radiology during or after taking this medication
  • Adequate bone marrow. liver and renal function

Exclusion Criteria:

  • Previous treatment with mTOR inhibitors (sirolimus, temsirolimus, everolimus, deforolimus).
  • Patients with any serious disease and/or an uncontrolled clinical condition
  • Patients on chronic treatment with corticosteroids or any other immunosuppressive agent
