NCT01462214

Brief Summary

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.

Outcome Measures

Primary Outcomes (3)

  • Number of Participants with Adverse Events as a Measure of Safety and Tolerability

    Outcome measure in Phase 1 and 2 part

    from 28 days up to 2 years

  • Number of patients progression-free at 4 months.

    Outcome measure in phase 2 part

    4 months

  • Depletion of circulating CD4+CD25+ regulatory T cells

    Treatment schedule that most selectively induces CD4+CD25+ Treg depletion in phase 1 part will be selected for phase 2.

    28 days

Secondary Outcomes (4)

  • Response rate

    2 years

  • Frequency of tumor infiltrating CD4+CD25+FOXP3+ regulatory T cells.

    2 years

  • Peripheral blood drug levels of everolimus and cyclophosphamide

    2 years

  • Overall survival

    2 years

Interventions

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.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients with histologically or cytologically confirmed clear-cell mRCC with progressive disease and not amenable to or progressive on or within 6 months of stopping treatment with a VEGF receptor tyrosine kinase inhibitor (sunitinib (or pazopanib) ± sorafenib).
  • Prior therapy with cytokines (i.e. IL-2, interferon) and/or VEGF-ligand inhibitors (i.e. bevacizumab) is permitted.
  • Patients with brain metastases are eligible if they have been stable for at least two months post-radiation therapy or surgery.
  • Aged 18 years or older.
  • 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.

You may not qualify if:

  • 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.
  • Immunosuppressive agents within 3 weeks of study entry, except for low dose corticosteroids when given for disorders such as rheumatoid arthritis, asthma, or adrenal insufficiency. Topical or inhaled corticosteroids are permitted.
  • 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.
  • Macroscopic hematuria
  • Prior therapy with mTOR inhibitors. 10. Known hypersensitivity to everolimus or other rapamycins (sirolimus/temsirolimus) or to its excipients.
  • Pregnant or nursing women, or women who were of childbearing potential and who were not utilizing an effective contraceptive method. A woman of childbearing potential is defined as a female who is biologically capable of becoming pregnant. Men with partners of childbearing potential not using an effective method of contraception. (Use of effective contraceptives must continue for 3 months after the last dose of everolimus).
  • Presence of any significant central nervous system or psychiatric disorder(s) that would hamper the patient's compliance.
  • Uncontrolled diabetes as defined by fasting serum glucose \> 2 ULN, severely impaired lung function.
  • Cirrhosis/chronic active hepatitis/chronic persistent hepatitis, history of HCV infection (for hepatitis screening indications see section 3.3).
  • Drug or alcohol abuse.
  • Any other major illness that, in the investigator's judgment, substantially increased the risk associated with the subject's participation in the study.
