Scientific title | A Phase I Study of Pembrolizumab anti PD-1 monoclonal antibody in combination with Radiotherapy in locally advanced Non-Small Cell Lung Cancer (NSCLC) |
Study acronym | PARIS |
Study objectives | The aim of this study is to determine the recommended phase II dose of pembrolizumab, in combination with a standard dose of radical thoracic radiotherapy, in patients with locally advanced non-small cell lung cancer (NSCLC), in order to be used in future phase II trials. The safety and toxicity of the combination of pembrolizumab (at the recommended dose) and radiotherapy are also be investigated. |
Ethics approval(s) | North West - Greater Manchester South Research Ethics Committee, 22/05/2017, rec: 17/NW/0242 |
Health condition(s) or problem(s) studied | Lung Cancer |
Intervention | Participants receive the first dose of pembrolizumab two weeks before the start of radiotherapy. Pembrolizumab is subsequently delivered every three weeks, starting on the first day of radiotherapy and are continued after completion of radiotherapy for up to 12 months. Participants receive radiotherapy for up to six and a half weeks. As this combination of treatment has not been given before, participants are registered initially into a dose finding phase where dose limiting toxicities (DLTs) is monitored during and for 12 weeks after completion of combined pembrolizumab and thoracic radiotherapy at each dose level in order to confirm the recommended phase II dose. Participants are given a different dose of pembrolizumab treatment depending on the group or ‘cohort’ they are recruited into. The starting dose of pembrolizumab for the first patients are 200 mg (dose level 1). This dose may be reduced to a dose of 100 mg (dose level -1) if unacceptable numbers of dose limiting toxicities are experienced at dose level 1. A maximum of 12 participants are treated in the dose finding part of the study aiming to establish the recommended phase II dose (RP2D). Once the recommended phase II dose is found, an expanded cohort of 13 participants are treated at this dose of pembrolizumab to obtain further safety data. During radiotherapy treatment the patient are seen weekly for follow-up. After completion of combination pembrolizumab and radiotherapy treatment, patient visits are scheduled at these time-points: 1. Weekly visits until toxicity resolved to grade 0-1 after radiotherapy. Patients in the dose finding cohort will also be seen weekly to week four regardless of toxicity. 2. Patients on maintenance Pembrolizumab: Three weekly visit up to 12 months 3. Patients not on maintenance Pembrolizumab: Monthly visits for up to four months post RT and then at months six, nine and 12. 4. CT scan assessment within a month of completing RT, three, six and 12 months (following RT) Thereafter, follow-up visits are scheduled according to host institution protocol. All participants, including those withdrawn due to toxicity, are followed up for adverse reactions and serious adverse reactions until death, withdrawal of consent, or the end of the study (whichever occurs first). |
Intervention type | Other |
Primary outcome measure | 1. Recommended phase II dose is measured using the amount of participants in the dose finding phase experiencing dose limiting toxicity (DLT) in the time period during and for 12 weeks after treatment with combined Pembrolizumab and thoracic radiotherapy 2. Dose limiting toxicity is measured using toxicities experienced from the start of treatment to 12 weeks post combination therapy |
Secondary outcome measures | 1. Safety profile of Pembrolizumab combined with thoracic RT (acute and late toxicity) is measured by assessing the occurrence of SAEs, SARs, and SUSARs until 90 days after the participant has stopped trial treatment. The toxicity profile is measured by assessing the occurrence of adverse events until 30 days after the participant has stopped trial treatment. 2. Treatment compliance of Pembrolizumab combined with thoracic RT is measured by recording dose reductions, delays, omissions, and withdrawals throughout each participant’s treatment on the study 3. Best overall response to Pembrolizumab combined with thoracic RT is measured using the RECIST criteria from the start of treatment until disease progression/recurrence (taking as reference for progressive disease the smallest measurements recorded since the treatment started) 4. Best overall response to Pembrolizumab combined with thoracic RT measured according to immune-related response criteria (irRC) is measured as the best confirmed irRC overall response over the study as a whole, recorded between the date of first dose until the last tumour assessment before subsequent therapy (except for local palliative radiotherapy for painful bone lesions) for the individual participant 5. Progression-free survival is measured using date of registration to first documented evidence of disease progression or death 6. Overall survival is measured from participant records from date of registration to death |
