E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To find a safe and effective dose of the trial drug when given in combination with gemcitabine and cisplatin chemotherapy. |
|
E.2.2 | Secondary objectives of the trial |
To find out about potential side effects of the combination of the SGI-110 and gemcitabine/cisplatin chemotherapy. To understand the effect that the combination of SGI-110 drug and chemotherapy have on blood and cancerous tissue. To understand how SGI-110 is processed through the body To evaluate whether it is safe and feasible to administer SGI-110 and chemotherapy to patients with muscle invasive bladder cancer prior to them having cystectomy.

E.4 | Principal exclusion criteria |
All Patients: 1. Unresolved toxicities from prior therapy greater than CTCAE v4.03 grade 1 (with the exception of alopecia) at the time of registration 2. Prior radiotherapy to > 30% of bone marrow 3. Major surgery within 30 days 4. Any investigational medicinal product within 30 days 5. Allergy or other known intolerance to any of the proposed study drugs including supportive agents and inclusive of G-CSF and locally utilised anti-emetics 6. Previously-identified central nervous system metastases unless treated and clinically stable and not requiring steroids for at least 4 weeks prior to the start of trial treatment 7. Coronary artery bypass graft, angioplasty, vascular stent, myocardial infarction, unstable angina pectoris or congestive cardiac failure (New York Heart Association ≥ grade 2) within the last 6 months 8. Women who are pregnant or breast feeding. (Women of child-bearing potential must have a negative pregnancy test performed within 7 days prior to the start of trial treatment) 9. Patients of child-bearing potential who are not using, or who are unwilling to use, a highly effective method of contraception 10. Any patient who, in the judgment of the local investigator, is unlikely to comply with trial procedures, restrictions or requirements
Patients In The Dose Expansion Phase: 11. Recent or current separate other malignancy. Current non-melanoma skin cancer, cervical carcinoma in situ or incidental localised prostate cancer is permissible. Participants with a history of a separate other malignancy having completed all active treatment 2 or more years previously may be entered

E.5 End points |
E.5.1 | Primary end point(s) |
To establish a recommended phase II dose and schedule (RP2D) for SGI-110 when combined with GC chemotherapy from both:
• the MTD based on defined criteria for dose limiting toxicity (DLT) assessed by Common Terminology Criteria for Adverse Events (CTCAE) v4.03 and
• the Maximally Biologically Effective Dose (MBED) based on plasma DNA LINE-1 methylation and haemoglobin F (HbF) re-expression status
|
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Patients assessed for toxicity throughout treatment until the last dose of last patient in the dose escalation phase. This may be through reaching the final cohort or meeting the stopping rules for cohorts 1, 2 or 3. Blood samples will be taken according to protocol for pharmacodynamics analysis.
|
|
E.5.2 | Secondary end point(s) |
1. Toxicity of SGI-110 in combination with gemcitabine and cisplatin chemotherapy in comparison to the chemotherapy alone.
2. Pharmacokinetics of SGI-110 when in combination with GC
3. Pathological complete response rates (dose expansion phase)
4. Biomarker Assessment of SGI-110
