Measure
NKTR-214, Anti-PD Therapy Plus Palliative Radiation
Cycle 1 consists of anti-PD-1 therapy (200mg) and NKTR-214 (0.006 mg/kg3 administered intravenously), followed by palliative radiation (8 Gy x 3 or 4 Gy x 5 fractions) combined with anti-PD-1 therapy and NKTR-214 in cycle 2. In subsequent cycles participants will receive NKTR-214 and anti-PD-1. NKTR-214: Bempegaldesleukin (NKTR-214) is an immunotherapeutic protein prodrug specifically designed to activate the patient's immune system for the treatment of cancer by providing a controlled, sustained signal to the interleukin-2 (IL-2) receptor pathway (pharmacological classification: immunostimulatory interleukin cytokine) anti-PD-1 therapy: immunotherapy drug, monoclonal antibody Palliative Radiation: radiation to relieve symptoms

Toxicities ≥ Grade 3 is defined by the NCI Common Terminology Criteria for Adverse Events (CTCAE) version 5.0. Toxicities not "unrelated" to treatment, will be considered treatment-related. Adverse events are evaluated by the physician graded from 1-5 where 1 = mild, 2 = moderate, 3 = severe, 4 = life threatening, and 5 = death.

European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire (EORTC QLQ-C30) is a measure of health-related quality of life for cancer patients participating in clinical trials. It scores the following domains from 0-100 where higher global or functional scores indicate increased quality of life and higher symptom scores indicate increased symptoms: Global health status (QL2), Physical functioning (PF2), Role functioning (RF2), Emotional functioning (EF), Cognitive functioning (CF), and Social functioning (SF).

The EQ-5D is a 5 question measure of mobility, self-care, usual activities, pain/discomfort, and anxiety/depression plus an overall measure of health reported on a visual analog scale. Participant counts are reported for each of 5 dimensions: mobility, self-care, usual activities, pain / discomfort, anxiety / depression.
