Clinical Trial Summary

ACTOv will compare standard 3-weekly carboplatin (AUC5), to carboplatin delivered according to an AT regimen. The AT regimen will modify carboplatin dose according to changes in the clinical-standard serum biomarker CA125 as a proxy measure of total tumour burden and an individual patient's response to the most recent chemotherapy treatment. AT could prolong sensitivity to carboplatin and extend tumour control, while simultaneously reducing chemotherapy dose and drug-induced toxicity. Carboplatin is a low cost and low toxicity drug that has an enduring and central role in ovarian cancer treatment.

7. Evidence of any other disease, metabolic dysfunction, physical examination finding or laboratory finding giving reasonable suspicion of a disease or condition that contra-indicated the use of an investigation drug or puts the patients at high risk for treatment-related complications.

8. Other psychological, psychiatric, social or medical condition, physical examination finding or a laboratory abnormality that the Investigator considers would make the patient a poor trial candidate or could interfere with protocol compliance or the interpretation of trial results.

11. Patients with spinal cord compression unless considered to have received definitive treatment for this and evidence of clinically stable disease for 28 days prior to randomisation.

12. Pregnant or breast-feeding women are excluded. Women of childbearing potential will be excluded unless effective methods of contraception are used from signing of the informed consent, throughout the period of taking study treatment and for at least 6 months after last dose of trial drug(s).

13. Inability to attend or comply with treatment or follow-up scheduling.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Modified Progression Free Survival (mPFS)	Measured from the date of randomisation to the date of objective progression (investigator assessed using RECIST v1.1) but comparing CT scans to the baseline CT rather than the radiological nadir), clinical progression or death from any cause (in the absence of progression)	From the date of randomisation until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 4 years.
Secondary	Acceptability (1/2)	the number of eligible patients approached who accept randomisation and continue to receive treatment	From the date of randomisation to the first dose of treatment (within 28 days from randomisation)received by patient.

Secondary	Acceptability (2/2)	the proportion of eligible patients approached who accept randomisation and continue to receive treatment	From the date of randomisation to the first dose of treatment (within 28 days from randomisation)received by patient.
