About this trial
This is a master prospective Phase I-II trial evaluating feasibility and efficacy of stereotactic magnetic resonance (MR) guided adaptive radiation therapy (SMART) in patients with cancer.
* The phase 1 study will evaluate the feasibility and safety of delivering SMART in patients with cancer. * Phase 2 will evaluate efficacy of SMART with specific reference to tumor control and improvement in patient reported outcome measures

Trial outcomes
Primary outcomes
Delivery Success Rate for SMART across multiple tumors-Phase I
Enrolling patients and delivering SMART on the MR Linac
Tumor visualization-Phase I
Assessing tumor using MR guidance before, during and after MR-guided treatment patient
Plan creation-Phase I
Generating adaptive plans
Rate of Improvement in Tumor Control-Phase II
Statistical power will be defined in each cohort individually and will be specific to each disease site tested.
Secondary outcomes

Duration of treatment-Phase 1
Duration of treatment with goal of \>80% of cases treated within 90 minutes
Number of treatment fractions-Phase1
Number of treatment fractions that would have resulted in unacceptably high dose (exceeding constraint) to an OAR without SMART
Number of Participants with long term toxicity-Phase II
assessing long-term (12 month) toxicity in patients receiving SMART
