Robotic Systems Evaluation for Peripheral Pulmonary Lesions (RISE Trial)

July 29, 2026 updated by: Case Comprehensive Cancer Center

Robotic Systems Evaluation for Peripheral Pulmonary Lesions: A Randomized Trial (RISE Trial)

This is an investigator-initiated cluster randomized control trial. The primary objective is to compare the diagnostic yield of two Food and Drug Administration (FDA) cleared national robotic assisted bronchoscopy platforms - the Monarch™ Platform and the ION™ Endoluminal System - in participants undergoing bronchoscopy to evaluate peripheral pulmonary lesions (PPLs). Participants will undergo their scheduled robotic assisted bronchoscopy (RAB) using one of these platforms.

Detailed Description

Roughly 1.6 million lung nodules are identified every year in the United States. When tissue sampling is required, robotic-assisted bronchoscopy (RAB) systems are increasingly used to reach peripheral targets inaccessible to standard bronchoscopy.

Robotic-assisted bronchoscopy (RAB) has rapidly evolved as a promising modality for sampling PPLs. Two FDA-cleared robotic platforms are currently in clinical use: the ION™ Endoluminal System (Intuitive Surgical, Inc., Sunnyvale, CA) and the Monarch™ Platform (Johnson & Johnson MedTech / Auris Health, Redwood City, CA). Both platforms were cleared through the FDA 510(k) pathway, which requires demonstration of substantial equivalence to predicate devices but does not mandate comparative effectiveness data prior to commercialization.

The ION™ system uses shape-sensing fiber-optic technology to track catheter position with high precision throughout the bronchial tree. It has been shown in multiple studies to achieve diagnostic yields ranging from 67-85%, with enhanced performance when combined with intraprocedural cone-beam computed tomography (CBCT). The recent RELIANT trial (the first cluster-randomized controlled trial in interventional pulmonology) demonstrated that ION™ was non-inferior to electromagnetic navigation bronchoscopy (ENB) with integrated digital tomosynthesis, with diagnostic yields of 77.8% and 75.5% respectively (P for non-inferiority = 0.007).

The Monarch™ platform uses a hybrid approach combining electromagnetic tracking and robotic catheter control with a continuously visualizing bronchoscope (4-way articulation). A key feature of the Monarch™ is direct bronchoscopic vision throughout navigation, enabling real-time assessment of the airways and the target lesion. The Monarch™ has received additional FDA clearance for bronchoscopic transparenchymal nodule access (BTPNA), allowing access to lesions without a direct airway path. Published studies report diagnostic yields of 66-81% for the Monarch™ platform, though most are single-center, non-randomized studies with varying definitions of diagnostic yield, co-intervention use, and did not fully use integrated intraprocedural imaging (including fluoroscopy and CBCT, as available and integrated).

Critically, no randomized or high-quality comparative study has directly compared the ION™ and Monarch™ platforms head-to-head with integrated intraprocedural imaging. As both systems are now available at University Hospitals Cleveland Medical Center and represent substantial capital expenditures, high-quality prospective comparative data are urgently needed to guide clinical decision-making and resource allocation. This trial leverages the existing dual-platform clinical infrastructure at UHCMC to conduct a pragmatic, cluster-randomized, non-inferiority trial embedded within routine clinical care

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Other: Monarch Platform
This study is being conducted at a hospital that has two bronchoscopy procedure rooms (BPRs). The unit of the randomization is the BPR day. Each day, one BPR will be randomized to the Monarch platform and the other to the ION platform. Participants in this arm will have undergone their RAB via the Monarch platform.
The Monarch™ (Monarch) platform is one of two FDA-cleared robotic platforms currently in clinical use for robotic-assisted bronchoscopy (RAB). It uses a hybrid approach combining electromagnetic tracking and robotic catheter control with a continuously visualizing bronchoscope (4-way articulation).

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Diagnostic yield defined as the proportion of procedures that result in the acquisition of lesional tissue
Time Frame: Up to Day 14
Diagnostic yield is defined as the proportion of procedures that result in the acquisition of lesional tissue. This will be measured for both procedures conducted via the Monarch platform and the ION platform.
Up to Day 14

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Duration of the robotic bronchoscopy procedures
Time Frame: Day 0
The duration of the robotic bronchoscopy procedure will be measured in minutes for both the Monarch platform and the ION platform.
Day 0
Safety, measured by the number of complications
Time Frame: Up to Day 7
Safety will be measured by the number of complications that occur within 7 days of the procedure for both the Monarch platform group and the ION platform group.
Up to Day 7
Radiation exposure
Time Frame: Day 0
Radiation exposure is defined as the radiation dose delivered to the participant during the study bronchoscopy and is recorded as a dose area product in milligray per centimeters squared (mGy/cm2). Radiation exposure is measured for both the Monarch platform group and the ION platform group.
Day 0
Rate of additional diagnostic procedures required within 12 months
Time Frame: Up to 12 months
The rate of additional diagnostic procedures required within 12 months of the study bronchoscopy will be assess for both the Monarch platform group and the ION group.

Diagnostic accuracy at 12 months post-biopsy
Time Frame: Up to 12 months
Diagnostic accuracy at 12 months post-biopsy is defined as the number of true positive lesions (malignant) plus true negative lesions (specific benign diagnosis) with no evidence of malignancy at 12-month follow-up (no interval biopsy diagnostic of malignancy, regression on CT or stable size with no plan for repeat diagnostic procedure), divided by the total number of biopsied lesions. This will be assessed for both the Monarch platform group and the ION platform group.
Up to 12 months
