In the present phase 1-2 study the investigators aim to determine whether depletion of Tregs using metronomic cyclophosphamide can enhance the antitumor efficacy of everolimus in patients with mRCC not amenable to or progressive after a VEGF-receptor tyrosine kinase inhibitor containing treatment regimen. In the phase 1 part of the study the investigators will determine the optimal CD4+CD25+ regulatory T cell-depleting dose and schedule of metronomic oral cyclophosphamide when given in combination with a fixed dose (10 mg daily) of everolimus. In the phase 2 part of the study the investigators will subsequently evaluate whether the number of patients who are cancer progression free at 4 months can be increased from 50% to 70% by adding metronomic cyclophosphamide (in the dose and schedule determined in the phase 1 part) to everolimus. In addition to efficacy, the investigators will evaluate treatment toxicity to determine whether this combination strategy is feasible and safe.

Primary Outcome Measures:
  • Number of Participants with Adverse Events as a Measure of Safety and Tolerability [ Time Frame: from 28 days up to 2 years ]
    Outcome measure in Phase 1 and 2 part

    Outcome measure in phase 2 part

  • Depletion of circulating CD4+CD25+ regulatory T cells [ Time Frame: 28 days ]

Secondary Outcome Measures:
  • Response rate [ Time Frame: 2 years ]
  • Frequency of tumor infiltrating CD4+CD25+FOXP3+ regulatory T cells. [ Time Frame: 2 years ]
  • Peripheral blood drug levels of everolimus and cyclophosphamide [ Time Frame: 2 years ]

Estimated Enrollment: 96
Study Start Date: October 2011
Estimated Study Completion Date: January 2017

Intervention Details:
    Drug: Everolimus
    Patients will be treated with low-dose oral cyclophosphamide (8 different dose levels and schedules) in combination with fixed dose (10 mg) everolimus in patients with mRCC.
Detailed Description:
This is a phase I/II, national multi-center study of different doses and schedules of low-dose oral cyclophosphamide in combination with fixed dose everolimus in patients with mRCC not amenable to or progressive after a VEGF-receptor tyrosine kinase inhibitor containing treatment regimen. Phase I part: Patients will be enrolled in cohorts of 5 per dose level. The first 5 patients enrolled will be assigned to dose level 0 in order to assess immune and angiogenic effects caused by everolimus monotherapy. The second 5 patients enrolled will be assigned to dose level 1. If there are ≤1 dose-limiting toxicities (DLTs) experienced by the first 5 patients in a cohort during the first 28 days after the first study treatment, further patients will be entered in the next dose level. Entry of patients into the expansion cohort will not occur until at least 28 days after the last patient in the escalation phase received his/her first study treatment. At the final dose level recommended for the phase II study a minimum of 10 patients will be treated. Phase II part: In the phase 2 part of the study up to 56 patients will be treated at the dose level that has been selected based on its capacity to most selectively deplete circulating Treg levels in the phase 1 part of the study. Based on data of patients with mRCC treated with everolimus monotherapy after previous treatment with sunitinib ± sorafenib, the investigators aim to increase the number of patients who are alive and cancer progression free at 4 months from 50% to 70% by adding metronomic cyclophosphamide. In addition, the investigators consider this increase meaningful as long as the combination treatment does not cause combination treatment related toxicity ≥ grade 3 in ≥ 30% of patients.

Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • No other current malignant disease, except for basal cell carcinoma of the skin.
  • WHO performance status 0-2.
  • Life expectancy of at least 12 weeks.
  • Adequate hematologic function: ANC ≥ 1.5 x 109/L, platelets ≥ 100 x 109/L, Hb ≥ 6.0 mmol/L.
  • Adequate hepatic function: serum bilirubin ≤ 1.5 x ULN, ALT and AST ≤ 2.5 x ULN (or ≤ 5 times ULN if liver metastases are present).
  • Adequate renal function: calculated creatinine clearance ≥ 50 ml/min.
  • Measurable or evaluable disease as defined by RECIST 1.1.
  • Patients with reproductive potential must use effective contraception. Female patients must have a negative pregnancy test.
  • Signed informed consent.
  • Able to receive oral medication.

Exclusion Criteria:

  • Patients currently receiving chemotherapy, immunotherapy, or radiotherapy or who have received these ≤ 4 weeks prior to visit 1. The wash-out period for sunitinib or sorafenib is at least 2 weeks from the first dose of the study medication.
  • Known human immunodeficiency virus (HIV) or other major immunodeficiency.

  • Patients with an active bleeding diathesis or on oral anti-vitamin K medication.
  • Patients with untreated CNS metastases with clinical symptoms or who have received treatment for CNS metastases within 2 months of study entry. Patients with treated CNS metastases, who are neurologically stable and off of corticosteroids for more than 2 months prior to study entry are eligible to enter the study.
  • Active infection or serious intercurrent illness, except asymptomatic bacteriuria.
  • Presence of unstable angina, recent myocardial infarction (within the previous 6 months), or use of ongoing maintenance therapy for life-threatening ventricular arrhythmia.

  • Cirrhosis/chronic active hepatitis/chronic persistent hepatitis, history of HCV infection (for hepatitis screening indications see section 3.3).
  • Drug or alcohol abuse.
