Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
It is planned to test the hypothesis that we can reliably establish mixed chimerism in humans using a non-myeloablative regimen and that we can decrease the incidence of graft rejection by the addition of 3 doses of fludarabine (30 mg/m2 given days -4, -3, -2) before 200 cGy TBI. Mixed chimerism will be defined as the detection of donor cells after transplant at > than 1% and <= 95% of the eripheral blood CD3+ cell population. Patients with low levels of T cell chimerism or those with continued evidence of malignancy (without GVHD) will be evaluated for the effects of DLI on conversion to full chimerism and for anti-tumour activity. The source of stem cells will be G-CSF mobilised PBSC from apheresis products collected on two consecutive days infused into the patient on day 0. Donor lymphocyte infusions may be given starting 2 months post-transplant in an attempt to convert mixed chimerism to full donor chimerism and to eradicate the malignancy. A graded series of T cell doses will be employed to reduce the risks of severe GVHD. For unrelated donor transplants, Bone Marrow will be used a the stem cell source if PBSC is not available.

Outcomes
Primary outcome [1] 646 0
To estimate the risk of graft rejection associated with the addition of fludarabine to a non-myeloablative conditioning regimen for patients with malignant diseases treatable by allogeneic stem cell transplantation and compare this rate to that observed among patients previously treated without fludarabine.
Timepoint [1] 646 0
Secondary outcome [1] 1338 0
To estimate the rate of grade acute II/IV GVHD and chronic GVHD in patients treated with low-dose TBI, Fludarabine, PBSC infusion and immunosuppression with Cyclosporine and Mycophenolate Mofetil.
Timepoint [1] 1338 0

Eligibility
Key inclusion criteria
Patients with haematological malignancy or metastatic renal cancer who are not eligible for a curative autologous transplantation or who have failed prior autologous transplantation and are not suitable for ablative conditioning regimes due to a high risk of treatment related morbidity/mortality (eg age, prior autologous transplant, pre-existing medical conditions). Patients with NHL and CLL must have failed prior therapy with an alkylating agent and/or fludarabine, or be at high risk of relapse. Patients with multiple myeloma must have stage II or III disease and received prior chemotherapy.
