Study type
Description of intervention(s) / exposure
Guadecitabine (SGI-110) 60mg/m2 administered by treating clinician subcutaneously (SC) daily for five days (days 1-5) in 28-day treatment cycles. Treatment should be administered for at least six cycles in the absence of disease progression requiring alternative therapy. Treatment will continue indefinitely if tolerated for as long as patient derives benefit (i.e. complete remission, partial remission or stable disease).

3) Second malignancy currently requiring active therapy except:
a. Breast or prostate cancer stable on or responding to endocrine therapy.
b. Pre-existing or concurrently diagnosed MDS (including chronic myelomonocytic leukaemia), or AML with bone marrow blasts <31%.
c. Non-melanomatous skin cancers such as basal or squamous cell carcinomas.
4) Patients with known active central nervous system involvement.
5) Renal impairment with creatinine clearance (as estimated by the Cockroft-Gault or other medically acceptable formula) <30ml/min.
6) Liver cirrhosis / chronic liver disease Child-Pugh B or C; total serum bilirubin >2.5x upper limit of normal (ULN), except for subjects with Gilbert’s syndrome for whom the direct bilirubin is <2.5 ULN.
7) Known active human immunodeficiency virus (HIV), hepatitis B virus (HBV), or hepatitis C virus (HCV) infection not controlled on antiviral therapy. Inactive hepatitis carrier status or low viral hepatitis titre on antivirals is permitted.

9) Refractory congestive heart failure unresponsive to medical treatment; active infection resistant to all antibiotics; or advanced pulmonary disease requiring >2 litres per minute (LPM) oxygen.
10) Known illness or condition that, in the opinion of the investigator, predisposes the subject to high risk of noncompliance with the protocol.
11) Any uncontrolled intercurrent medical condition or laboratory abnormality, which would in the opinion of the investigator make participation unsafe.
12) Women of child-bearing potential must not be pregnant or breastfeeding and must have a negative pregnancy test at screening. Women of child-bearing potential and men with female partners of child-bearing potential must agree to practice 2 highly effective contraceptive measures during the study and for at least 3 months after completing treatment and must agree not to become pregnant or father a child while receiving treatment with guadecitabine and for at least 3 months after completing treatment.

Statistical methods / analysis
Sample size has been pragmatically determined and 20 patients are expected to be registered on the study in 24 months. With 20 evaluable patients, the maximum standard error for the overall response rate after six cycles of induction is 11.2%. This is considered to be a suitable level of precision for a phase II pilot study.
95% confidence intervals will be reported for ORR in the first six (induction) cycles for all patients and also for those patients in the AITL subgroup. A Bayesian approach will also be adopted to monitor and report the posterior probability distributions for ORR should such interim reports be required by the DMSC.

Brief summary
The purpose of this study is to test the safety, tolerability and anti-tumour activity of the research study drug, guadecitabine.

Who is it for?
You may be eligible for this study if you are an adult who has been diagnosed with T-cell non-Hodgkin lymphoma, which has (a) not been treated, (b) been deemed unsuitable for standard therapy or (c) have relapsed or refractory disease.

Study details
All participants will receive subcutaneous injections of guadecitabine for the first 5 days of a 28 day treatment cycle. Treatments will be given for at least 6 of these 28 day cycles. This is a safety and efficacy trial, so any adverse events will be recorded and the effect of the study treatment on the lymphoma will be monitored using a PET or CT scan.

This study will provide information about this study drug and allow subsequent study of this potential treatment for T-cell non-Hodgkin lymphoma.
