Study information

Scientific title

SGI-110 to potentiate platinum response: A phase Ib/randomised IIa open label clinical trial combining SGI-110 with cisplatin and gemcitabine chemotherapy for solid malignancies including bladder cancer


Study hypothesis

Phase I:
The aim of this phase is to find the optimum dose of gemcitabine (GC) for the treatment of bladder cancer to use in the phase II of the study.

Phase II:
The aim of this phase is to investigate the whether treatment with a combination of SGI-110 and GC or GC alone is most effective.

Ethics approval

Topic: Cancer; Subtopic: Bladder Cancer; Disease: Bladder (advanced), Bladder (superficial)


Phase I: Dose-escalation phase
Patients will be entered into sequential dose level cohorts and (at the relevant dose level). Escalating dose level cohorts (4 cohorts are planned) of SGI-110 + standard gemcitabine/cisplatin chemotherapy for up to 6 cycles of 21 days each.

Phase II: Dose expansion phase
Patients will be randomised to one of two groups.

Group 1: Participants receive 3-4 cycles (21 days each) of standard GC chemotherapy + SGI-110 (at the RP2D established in Phase I)

Group 2: Participants receive 3-4 cycles (21 days each) of standard GC chemotherap only.

Drug names

Primary outcome measures

To establish the Recommended Phase II Dose (RP2D) for SGI-110 when combined with GC within the first year of the study.

Secondary outcome measures

1. Investigation of other potential pharmacodynamic biomarkers for SGI-110 target is measured at the end of the study
2. Pharmacokinetics of SGI-110 when combined with GC are determined within the first year of the study
3. The pathological complete response rate of bladder cancer patients is measured at the end of the study
4. Toxicity profile of SGI-110 when combined with GC is measured throughout the trial

Participant inclusion criteria

All patients:
1. ECOG performance status of 0 or 1
2. Glomerular filtration rate estimation of = 60 mL/min according to either the Cockcroft and Gault formula or by Cr-51EDTA or Tc-99m DTPA clearance

Patients in the dose escalation phase:
Incurable histologically or cytologically confirmed, locally advanced or metastatic, solid cancer, for which the use of gemcitabine and cisplatin is a clinically appropriate treatment in the view of the local principal investigator. Any number of previous lines of systemic chemotherapy is permitted.

Patients in the dose expansion phase:
1. Bladder cancer with a pure or a predominant component of transitional cell carcinoma
2. Clinical stage T2-4a N0 M0
3. Planned to commence GC for 3 or 4 cycles with neoadjuvant (i.e. curative) intent prior to a planned radical cystectomy

Participant 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)

11. Any patient who has received a live vaccine within 4 weeks of initiation of their treatment

Patients in the dose expansion phase:
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.
