Brief Summary:
This phase II trial is studying how well CCI-779 works in treating patients with progressive metastatic neuroendocrine tumors. Drugs used in chemotherapy, such as CCI-779, work in different ways to stop tumor cells from dividing so they stop growing or die.

Condition or disease Intervention/treatment Phase
Metastatic Gastrointestinal Carcinoid Tumor Pulmonary Carcinoid Tumor Recurrent Gastrointestinal Carcinoid Tumor Recurrent Islet Cell Carcinoma Drug: temsirolimus Other: laboratory biomarker analysis Phase 2

Detailed Description:


I. To assess the objective tumor response rate (i.e. partial or complete responses as defined by the RECIST criteria) in patients with progressive metastatic neuroendocrine tumours given CCI-779.

II. To assess the stable disease rate and duration, time to progression, median survival time, 1-year survival rate and toxicity in patients with metastatic neuroendocrine carcinomas given CCI-779. As of 19 July 2010, overall survival follow-up is to be discontinued for the four remaining patients on long term follow-up. At that point in time, these patients had been off-treatment for 3 to 5 years. Time to progression and median survival times will be based on the currently available data.

III. To measure baseline levels of various elements up- and downstream of the mammalian target of rapamycin (mTOR). Where post-treatment biopsies are available, they will be analyzed for suppression of elements in the mTOR pathway as well as for any effect on cell cycle progression, apoptosis or anti-angiogenic effects.

OUTLINE: This is an open-label, multicenter study.

Patients receive CCI-779 IV over 30 minutes on days 1, 8, 15, and 22. Treatment repeats every 28 days for up to 6 courses in the absence of disease progression or unacceptable toxicity. Patients who achieve a complete response (CR) or partial response (PR) receive 2 additional courses beyond CR or PR.

Patients are followed up for survival.

Primary Outcome Measures :
  1. Objective Tumor Response Rate (Defined as Partial or Complete Response as Defined by the RECIST Criteria) [ Time Frame: Up to 8 years ]
    Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0) for target lesions and assessed by MRI: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), >=30% decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR + PR.

Secondary Outcome Measures :
  1. Stable Disease Rate Defined by RECIST Criteria [ Time Frame: Up to 8 years ]
    Potential association between variables will be measured using Pearson correlation coefficients, chi-square tests, one- or two-sample t-tests or logistic regression analyses as appropriate. Ninety-five percent confidence intervals will be constructed and selected results will be illustrated using figures and plots.

  2. Median Survival Time [ Time Frame: 3 ]
    Computed using the Kaplan-Meier method.

  3. Survival Rate [ Time Frame: 1 year ]
    Computed using the Kaplan-Meier method.

  4. Response and Stable Disease [ Time Frame: 2 months ]
    Assessed using RECIST criteria.Patients that had Stable disease for 2 months

  5. Number of Temsirolimus Treatment Cycle Analyzed for Toxicity [ Time Frame: Duration of participants treatment upto 16wks (4cycles) of treatment ]
    Safety and tolerability of treatment with Temsirolimus assessed using CTCAE v 3

  6. Time to Progression [ Time Frame: Up to 8 years ]

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

Inclusion Criteria:

  • Patients must have histologically or cytologically confirmed neuroendocrine tumours either of carcinoid histology or a carcinoma of pancreatic islet cell origin; small cell variant, endocrine organ carcinomas, and adrenal gland malignancies (including paragangliomas) are excluded from this study
  • Patients must have progressive metastatic disease defined by one of the following occurring within 6 months of study entry:

    • At least a 25% increase in radiologically or clinically measurable disease
    • Appearance of any new lesion or
    • Deterioration in clinical status
  • Patients must have measurable disease, defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded) as >= 20 mm with conventional techniques or as >= 10 mm with spiral CT scan
  • Previous local therapy (e.g. chemoembolization or bland embolization) allowed if completed > 6 weeks prior to study entry; for patients who received local therapy prior to study entry, there must be either progression of measurable disease documented within the treatment field, or must have measurable disease outside the treatment field prior to study entry
  • Previous chemotherapy, investigational agents or radioactive therapies (e.g. radioactive octreotide) allowed if completed > 4 weeks prior to study entry (> 6 weeks if last regimen contained BCNU or mitomycin C); for patients who received systemic therapy prior to study entry, there must be documented progression of measurable disease prior to study entry
  • Patients must not have disease that is currently amenable to surgery; prior surgery is allowed no less than 6 weeks prior to study entry
  • Previous radiation therapy is allowed if > 4 weeks have elapsed since delivery of a dose likely to have myelotoxic effects (e.g. ≥ 3000cGy to fields including substantial marrow)
  • Life expectancy of greater than 3 months
  • ECOG performance status ≤ 2 (Karnofsky ≥ 60%)
  • Leukocytes ≥ 3.0 x 10^9/L
  • Absolute neutrophil count ≥ 1.5 x 10^9/L
  • Platelets >= 100 x 10^9/L
  • Total bilirubin ≤ 1.25 x ULN
  • AST(SGOT)/ALT(SGPT) ≤ 3 x ULN; < 5 x ULN with liver metastases

  • Fasting serum cholesterol =< 350 mg/dL (9.0 mmol/L)
  • Triglycerides =< 400 mg/dL (4.56 mmol/L)
  • Must be willing and able to undergo tumor biopsy once before and once during experimental therapy; patients must have tumor lesions accessible for biopsy for correlative studies; in cases where there is a medical contraindication to tumor biopsy, exception may be granted upon discussion with the Principal Investigator/Chair
  • The effects of CCI-779 on the developing human fetus at the recommended therapeutic dose are unknown; for this reason, women of childbearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation; should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately
  • Ability to understand and the willingness to sign a written informed consent document

Exclusion Criteria:

  • Patients who have had chemotherapy or radiotherapy within 4 weeks (6 weeks for nitrosoureas or mitomycin C) prior to entering the study or those who have not recovered from adverse events due to agents administered more than 4 weeks earlier
  • Patients may not be receiving any other investigational agents concurrently or within 4 weeks of study entry
  • Patients with known brain metastases should be excluded from this clinical trial because of their poor prognosis and because they often develop progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events
  • History of allergic reactions attributed to compounds of similar chemical or biologic composition to CCI-779
  • Concurrent cancer from another primary site requiring treatment of any kind within the past 3 years; curatively treated non-melanoma skin cancer or in situ carcinoma of the cervix are allowed
  • Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
  • Pregnant women are excluded from this study because CCI-779 is an inhibitor of mRNA translation with the potential for teratogenic or abortifacient effects; because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with CCI-779, breastfeeding should be discontinued if the mother is treated with CCI-779
  • HIV-positive patients receiving combination anti-retroviral therapy are excluded from the study because of possible pharmacokinetic interactions with CCI-779; appropriate studies will be undertaken in patients receiving combination anti-retroviral therapy when indicated
