Trial Outcomes & Findings for Quad Shot Radiotherapy in Combination With Immune Checkpoint Inhibition (NCT NCT04454489)
NCT ID: NCT04454489
Last Updated: 2025-11-19
Results Overview
Overall response will be measured according to RECIST 1.1 criteria to determine the percentage of participants with either a partial or complete response and the corresponding 95% Clopper-Pearson exact confidence interval. The best overall response is the best response recorded from the start of the treatment across all time points. COMPLETE RESPONSE: Disappearance (or decrease to the point at which measurement is not possible) of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10 mm (the sum may not be "0" if there are target nodes) PARTIAL RESPONSE: At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum of diameters

Quad-shot Palliative Radiotherapy and Immunotherapy
Systemic therapy (ICI) and radiotherapy will be administered according to the standard of care, according to the treating medical oncologist and radiation oncologist, respectively
Pembrolizumab (immunotherapy): Pembrolizumab 200 mg will be given every 3 weeks to tumor progression or treatment tolerance.
Quad-shot palliative radiotherapy: - Each cycle of quad-shot radiotherapy will be comprised of 14.8 Gy in 4 fractions (3.7 Gy per fraction) delivered twice daily (at least 6 hours apart) over two consecutive days.
* All patients will receive 1 cycle of quad-shot radiotherapy between ICI cycles 2-3.
* Subsequent cycles may occur between immunotherapy cycles 6-7 and 11-12, if more than 1 cycle can be safely delivered and the patient has experienced less than a partial response at protocol-specified tumor assessments (after C5 and C10). The eligibility for subsequent cycles will be at the discretion of the treating radiation oncologist.
Therefore, the total prescription dose will be:
* 14.8 Gy in 4 fractions for those that complete 1 cycle (all patients will receive 1 cycle)
* 19.6 Gy in 8 fractions for those that complete 2 cycles
* 44.4 Gy in 12 fractions for those that complete 3 cycles

Timeframe: Up to 2 yearsPopulation: Five of the patients who started treatment were not evaluable for response. The number entered below is the percentage with a complete or partial response. A 95% Clopper Pearson exact confidence interval on the rate is reported.
Response rate will be measured as the following: Complete: Disappearance (or decrease to the point at which measurement is not possible) of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10 mm. Partial: At least a 30% decrease in the sum of diameters of target lesions. Progressive Disease: Greater than 20% increase in the sum of the longest diameters (SLD) taking as reference the smallest SLD recorded since the treatment started (nadir) and minimum 5 mm increase over the nadir. When sum becomes very small, increases within measurement error (2-3 mm) can lead to 20% increase. Stable Disease: Greater than 20% increase in the sum of the longest diameters (SLD) taking as reference the smallest SLD recorded since the treatment started (nadir) and minimum 5 mm increase over the nadir. When sum becomes very small, increases within measurement error (2-3 mm) can lead to 20% increase.

SECONDARY outcome
Timeframe: Up to 2 yearsPopulation: Five of the patients who started treatment were not evaluable for response. The number entered below is the percentage with a complete or partial response. A 95% Clopper Pearson exact confidence interval on the rate is reported.
Response rate will be measured using RECIST 1.1: Complete: Disappearance (or decrease to the point at which measurement is not possible) of all non-target lesions. All lymph nodes must be non-pathological in size (\< 10 mm short axis). Partial: Non-complete response/Non-progressive disease: Persistence of 1 or more non-target lesion(s). Progressive Disease: Unequivocal progression of existing non-target lesions. The appearance of one or more new lesions. Unequivocal progression should not normally trump target lesion status. It must be representative of overall disease status change, not a single lesion increase. Stable Disease: Greater than 20% increase in the sum of the longest diameters (SLD) taking as reference the smallest SLD recorded since the treatment started (nadir) and minimum 5 mm increase over the nadir. When sum becomes very small, increases within measurement error (2-3 mm) can lead to 20% increase.

Timeframe: Up to 2 yearsPopulation: Six patients had either a complete or partial response.
For the duration of response, among participants investigators will estimate both the mean duration and the corresponding 95% confidence intervals for the mean and inter-quartile range for the median. The duration of response at the target lesion will be defined as the duration from the time measurement criteria are met for complete response (CR) or partial response (PR) (whichever is first recorded) until the first date of recurrent or progressive disease.

Quad-shot palliative radiotherapy: - Each cycle of quad-shot radiotherapy will be comprised of 14.8 Gy in 4 fractions (3.7 Gy per fraction) delivered twice daily (at least 6 hours apart) over two consecutive days.
* All patients will receive 1 cycle of quad-shot radiotherapy between ICI cycles 2-3.
* Subsequent cycles may occur between immunotherapy cycles 6-7 and 11-12, if more than 1 cycle can be safely delivered and the patient has experienced less than a partial response at protocol-specified tumor assessments (after C5 and C10). The eligibility for subsequent cycles will be at the discretion of the treating radiation oncologist.
Therefore, the total prescription dose will be:
* 14.8 Gy in 4 fractions for those that complete 1 cycle (all patients will receive 1 cycle)
* 19.6 Gy in 8 fractions for those that complete 2 cycles
* 44.4 Gy in 12 fractions for those that complete 3 cycles

Quad-shot Palliative Radiotherapy and Immunotherapy
n=20 participants at risk
Systemic therapy (ICI) and radiotherapy will be administered according to the standard of care, according to the treating medical oncologist and radiation oncologist, respectively
Pembrolizumab (immunotherapy): Pembrolizumab 200 mg will be given every 3 weeks to tumor progression or treatment tolerance.
