- CNS leukemia.
- Preexisting cardiovascular disease. The only exception being well controlled essential hypertension with a sitting blood pressure (B.P.) of < 160 systolic and < 90 diastolic without any evidence of structural heart disease or one episode of myocardial infarction > 8 months ago. A past history of any of the following conditions is considered as exclusions to study participation:

- Congestive heart failure,
- Atrial fibrillation,
- Pulmonary hypertension,
- Anticoagulant drug therapy,
- Thromboembolic events,
- Cardiomyopathy or a myocardial infarction within the past 8 months.
- The PI and the Clinical Coordinator will be asked to verify that their referred patients do not have these exclusionary histories listed in 3.2 and a copy of this verification must be sent to the Sponsor before the Sponsor will approve of enrollment. Referring physicians will not need to sign. (Template for verification letter Appendix C).
- Pregnant or nursing women will be excluded from study.
- History of cirrhosis of the liver based on the Child-Pugh score of Class B or C are not eligible to participate. (Appendix B.)

About this study
Official title: A Phase II Study of A-dmDT390-bisFv(UCHT1) Fusion Protein in Patients With Cutaneous T Cell Lymphoma
This is a Phase II clinical trial aimed at treating a subgroup of patients with cutaneous T-cell lymphoma. The drug consists of a toxin, called diphtheria toxin, which is attached to an antibody that can specifically target cancerous T-cells. Our primary objectives are, therefore, to determine the patient subgroup with respect to disease burden who best responds to this experimental drug in treating CD3 positive T cell malignancies. We will be determining how the patient and their disease respond to this research agent.
The Clinical Response Data analysis from October 2014 done at the completion of the Phase I portion of A-dmT390-bisFv(UCHT1) fusion protein clinical trial showed that there were 25 evaluable patients who received all 8 doses varying between 2.5 and 11.25 µg/kg per dose. There were responses at all the lower dose levels up to 7.5 µg/kg per dose. The overall response rate was 36% and the complete response rate was 16% (when followed for 6 months). We have identified a subgroup of CTCL patients that have a very high response rate. If we exclude patients whose mSWAT scores never exceeded 50 (50% of skin surface area times a multiplier) and who never had lymph node involvement or stage III disease we are left with 9 patients. This subgroup has an overall response rate of 89% and a complete response rate of 50% (when followed for 6 months). Of these 4 patients currently in complete remission, three are long-term responders. Two are over 6 years in duration and one over 5 years duration. These may represent cures. The long time periods in the transition from partial response to complete response without treatment, 6 months to two years, suggests that the study drug in addition to exerting a direct killing effect on tumor also functions as an immunomodulator.
Read the detailed description
The purpose of this study is to further evaluate the clinical responses including response rate and duration and correlate with patient disease stage, tumor burden, anti-DT titer and degree of T cell depletion induced by A-dmDT390-bisFv(UCHT1) fusion protein for patients with surface CD3+ malignant diseases. The secondary objective is to further explore the toxicity profile of A-dmDT390-bisFv(UCHT1) fusion protein for a high-response subgroup of patients with CTCL whose disease stage has not progressed beyond stage IB/IIB with mSWAT < 50%. Patients will receive full supportive care including transfusions of irradiated washed blood and blood products, antibiotics, antiemetics, etc, when appropriate. However, other anti-neoplastic drugs or hematopoietic growth factors (e.g., erythropoietin, interleukin-11, G-CSF and GM-CSF) are not allowed. Treatment will consist of one 4 day cycle consisting of 2 daily infusions for a total of 8 treatments given on an outpatient basis. Patients will be monitored until day 14 for signs of late drug toxicity by a daily phone call from their health care provider. Subjects will be instructed on how to monitor their own blood pressure at home and encouraged to measure and chart their daily weights that they can report to their health care provider. Off-treatment follow-up will be based upon response. Patients who experience a partial or complete remission who later relapse can receive radiation treatment of new lesions and remain on study as this course is typical of responses to an immunomodulating drug. Patients will have a follow-up visit and testing on day 37. Patients with partial or complete remissions will have another follow-up visit on day 60, then every three months for 1 year, followed by annual visits to assess duration of the response. To accommodate patients, we are offering a travel reimbursement program. Due to the 4 days of consecutive infusions, we will reimburse the expense the patient would incur to travel to the participating institution for treatment.
Objectives:
- Evaluate the overall clinical responses including response rate and duration in a larger group of CTCL high-response patients to see if is higher than current therapies (>49%).
- Determine the complete response rate and duration of response of A-dmDT390-bisFv(UCHT1) fusion protein in a larger group of CTCL high-response patients to see if is higher than current therapies (>20%).
- Further define toxicities of A-dmDT390-bisFv(UCHT1) regimen in patients with CTCL who have been selected to be free from preexisting cardiac disease and never treated with Campath.
- Determine if correlations exist between disease stage, tumor burden, anti-DT titer and degree of T cell depletion and response rate and response duration.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing A-dmDT390-bisFv(UCHT1) in people with T-cell Lymphomas and T-cell Leukemia, run by Virogen Biotechnology Inc. at 5 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 16 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 29 Nov 2016. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 5 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Remission status (complete, partial, stable disease, progressive disease) (time frame: Time Frame: 6 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00611208, which also lists 4 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Nov 2016.
