Brief Summary:
The REFINE trial aims to asses whether giving an immunotherapy drug less-often to patients with advanced cancer, results in fewer side effects whilst continuing to be an effective treatment. The question will be assessed in different tumour types by means of different cohorts within an overarching trial protocol.

Condition or disease Intervention/treatment Phase
Renal Cell Carcinoma Melanoma Drug: Nivolumab Drug: Pembrolizumab Phase 2

Detailed Description:

In stage I eligible participants will be randomly assigned to either the standard interval (either 4 or 6 weeks) or the extended interval (either 8 or 12 weeks) following an initial 12 weeks of standard of care immunotherapy. Disease recurrence and survival will be assessed, along with quality of life and health economic outcomes. The trial includes a feasibility outcome by which recruitment feasibility will be assessed.

Immunotherapy drugs are a standard treatment option for advanced kidney cancer, bladder cancer, melanoma and some lung cancers. These drugs work by stimulating the body's own immune system to fight against cancer cells. Clinical trials have proven the effectiveness of immunotherapy drugs, such as ipilimumab, nivolumab or pembrolizumab, in the treatment of different cancers. However the best way to give these drugs is not known.

Primary Outcome Measures :
  1. Progression Free Survival [ Time Frame: 1 year 9 months follow-up ]
    Time to event


Secondary Outcome Measures :
  1. Overall survival [ Time Frame: 1 year 9 months follow-up ]
    Overall survival

  2. Quality of Life (QoL) [ Time Frame: 1 year 9 months follow-up ]
    EQ-5D-5L questionnaires

  3. Overall Response Rate (ORR) [ Time Frame: 1 year 9 months follow-up ]
  4. Duration of Response [ Time Frame: 1 year 9 months follow-up ]
  5. Incidence of Treatment-Emergent Adverse Events [ Time Frame: 1 year 9 months follow-up ]
    Safety data analysis will be conducted on all subjects receiving at least one dose of study medication. The number and percentage of subjects experiencing an AE and the number of events will be summarized by arm. Information by severity will be examined with a focus on Grade 3-5 events using the Common Terminology Criteria for Adverse Events (CTCAE v5.0)

  6. Health economic outcome: Mean incremental cost per patient [ Time Frame: 1 year 9 months follow-up ]
    Resource use will be collected via a modified version of the participant-completed Client Service Receipt Inventory (CSRI) and from treatment and concomitant medication data

  7. Health economic outcome: Mean incremental QALYs per patient [ Time Frame: 1 year 9 months follow-up ]
    QALYs will be calculated from the utility scores calculated from participant responses to the EQ-5D-5L, as the area under the curve, adjusting for baseline differences using regression analysis

  8. Health economic outcomes: Cost-utility analysis assessing cost-effectiveness of reduced vs. standard frequency administration [ Time Frame: 1 year 9 months follow-up ]
    CSRI questionnaire and Published NHS Reference Costs or Personal Social Services Research Unit (PSSRU) Unit Costs of Health and Social Care will be applied to service use information, and British National Formulary costs used where required for medications, with secondary analyses using any available information on patient access scheme discounts.

    1. Haemoglobin ≥9.0g/dL (transfusions will be allowed within 2 weeks prior to randomisation in order to achieve the entry criteria).
    2. Absolute neutrophil count (ANC) ≥1.5 x 109/L (≥1500 per mm3).
    3. Platelet count ≥100 x 109/L (≥100,000 per mm3).
    4. Bilirubin ≤1.5 x ULN (This will not apply to subjects with confirmed Gilbert's syndrome (i.e., persistent or recurrent hyperbilirubinemia that is predominantly unconjugated in the absence of haemolysis or hepatic pathology), who will be considered eligible only in consultation with their physician).
