Dendritic Cell-based Immunotherapy Combined With Low-dose Cyclophosphamide in Patients With Malignant Mesothelioma
Lead Sponsor:
Erasmus Medical Center
Conditions:
Malignant (Pleural) Mesothelioma
Eligibility:
All Genders
Phase:
PHASE1
Brief Summary
Earlier the investigators determined the safety and feasibility of tumor lysate-pulsed dendritic cells as therapeutic adjuvants in mesothelioma patients. Because pre-clinical data in mice had shown th...
Detailed Description
Currently there is no satisfactory low-toxicity treatment for patients with mesothelioma (MM). Based on studies in other types of cancer in humans where beneficial effects were obtained, and based on ...
Eligibility Criteria
Inclusion
- Inclusion criteria:
- Patients with clinically and histological or cytological confirmed newly diagnosed MM, that can be measured in two dimensions by a radiologic imaging study.
- Patients must be at least 18 years old and must be able to give written informed consent.
- Patients must be ambulatory (Karnofsky scale \> 70, or WHO-ECOG performance status 0,1, or 2) and in stable medical condition. The expected survival must be at least 4 months.
- Patients must have normal organ function and adequate bone marrow reserve: absolute neutrophil count \> 1.5 x 109/l, platelet count \> 100 x 109/l, and Hb \> 6.0 mmol/l.
- Positive DTH skin test (induration \> 2mm after 48 hrs) against at least one positive control antigen tetanus toxoid.
- Stable disease or response after chemotherapy.
- Availability of sufficient tumor material of the patient.
- Ability to return to the Erasmus MC for adequate follow-up as required by this protocol.
- Able to tolerate oral therapy
- No impairment of gastrointestinal (GI) function or GI disease that may affect or alter absorption of CTX (e.g., mal-absorption syndrome, history of total gastrectomy/significant small bowel resection)
- No history of allergic reactions (≥ grade 3 or 4) to compounds of similar chemical or biologic composition to CTX (i.e., alkylating agents)
- No known intolerance or hypersensitivity reaction to CTX
- Exclusion criteria:
- Conditions that make the patient unfit for chemotherapy or progressive disease after 4 cycles of chemotherapy.
- Pleurodesis at the affected side before the pleural fluid is obtained.
- Medical or psychological impediment to probable compliance with the protocol.
- Patients on steroid (or other immunosuppressive agents) are excluded on the basis of potential immune suppression. Patients must have had 6 weeks of discontinuation and must stop of any such treatment during the time of the study.
- No prior malignancy is allowed except for adequately treated basal cell or squamous cell skin cancer, superficial or in-situ cancer of the bladder or other cancer for which the patient has been disease-free for five years.
- Serious concomitant disease, no active infections. Patients with a history of autoimmune disease or organ allografts, or with active acute or chronic infection, including HIV (as determined by ELISA and confirmed by Western Blot) and viral hepatitis (as determined by HBsAg and Hepatitis C serology).
- Patients with serious intercurrent chronic or acute illness such as pulmonary (asthma or COPD) or cardiac (NYHA class III or IV) or hepatic disease or other illness considered by the study coordinator to constitute an unwarranted high risk for investigational DC treatment.
- Patients with a known allergy to shell fish (may contain KLH).
- Pregnant or lactating women.
- Patients with inadequate peripheral vein access to perform leukapheresis
- Concomitant participation in another clinical trial
- An organic brain syndrome or other significant psychiatric abnormality which would comprise the ability to give informed consent, and preclude participation in the full protocol and follow-up.
- Absence of assurance of compliance with the protocol. Lack of availability for follow-up assessment.
