Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Timepoint(s) of evaluation of this end point: In Cohort 1 the timepoint of evaluation is at 4 weeks. In Cohort 2 the timepoints of evaluation are at 4 weeks and 12 weeks.;Main Objective: The principal research objective for Cohort 1 is to find out whether CT327 (an ointment with a drug called a TRK inhibitor in it) is a safe treatment for patients with CYLD defective tumours (lumps). The principal research objective for Cohort 2 is to investigate whether CYLD defective tumours (lumps) respond to CT327.;Secondary Objective: Secondary objectives for Cohort 1 are to measure quality of life (questionnaire), skin and tumour (lump) appearance and patient treatment compliance (patient diary). Secondary objectives for Cohort 2 are to establish the way that the study drug works on the size of CYLD defective tumours (lumps) using genetic techniques and protein measurement.;Primary end point(s): The primary outcome measure for Cohort 1 is the number of patients with severe treated skin site reactions as determined by Modified Draize score, after a 4 week treatment period. The primary outcome measure for Cohort 2 is the proportion of tumours responding to treatment by 12 weeks. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): In Cohort 1 the secondary endpoints are; Impact of disease on quality of life, acceptability of treatment, and concentration of CT327 in plasma. In Cohort 2 the secondary endpoints are; the number of adverse events within a planned 12 week treatment period, expression of targets of TRK signalling in tumour biopsies as determined by QPCR and immunohistochemistry, concentration of CT327 in plasma and a proportion of tissue samples. ; Timepoint(s) of evaluation of this end point: The timepoint of evaluation in cohort 1 is at 4 weeks. The timepoints of evaluation in cohort 2 is at 4 weeks and 12 weeks. | — |
