Requests for Oral Presentations: This public workshop includes a public comment session and topic-focused sessions. During online registration you may indicate if you wish to present during a public comment session or participate in a specific session, and which topics you wish to address. FDA has included general topics in this document. FDA will do its best to accommodate requests to make public comments. Individuals and organizations with common interests are urged to consolidate or coordinate their presentations, and request time for a joint presentation, or submit requests for designated representatives to participate in the focused sessions. Following the close of registration, FDA will determine the amount of time allotted to each presenter and the approximate time each oral presentation is to begin, and will select and notify participants by September 15, 2015. All requests to make oral presentations must be received by September 1, 2015. If selected for presentation, any presentation materials must be emailed to Bahram Parvinian and Allison Kumar (see Contact Persons) no later than October 1, 2015. No commercial or promotional material will be permitted to be presented or distributed at the public workshop.
Comments: FDA is holding this public workshop to obtain information on challenges related to the design, development, and evaluation of critical care PCLC devices. In order to permit the widest possible opportunity to obtain public comment, FDA is soliciting either electronic or written comments on all aspects of the public workshop topics. The deadline for submitting comments related to this public workshop is September 1, 2015.
Regardless of attendance at the public workshop, interested persons may submit either electronic comments regarding this document to http://www.regulations.gov or written comments to the Division of Dockets Management (HFA-305), Food and Drug Administration, 5630 Fishers Lane, rm. 1061, Rockville, MD 20852.

Start Supplemental Information
PCLC medical devices are an emerging technology in the intensive care and emergency medicine settings that provides autonomous therapy adjustments to manipulate a physiological variable. For example, a closed-loop oxygen delivery device may automatically adjust the fraction of inspired oxygen when an individual's oxygen saturation level drifts too high or too low. PCLCs could benefit patients and practitioners by automating a number of tasks including adjustments to mechanical ventilation, anesthetic delivery, and fluid resuscitation. These devices may provide practitioners more resources to consider the course of treatment for an individual patient and improve resource allocation during times of medical surge (e.g., from mass casualty incidents). PCLC medical devices may also allow additional therapeutic and diagnostic capabilities by providing precise control of physiological variables by continuous manipulation of therapy that is impractical for a medical practitioner to perform.
Recent advances in medical device technology and control systems science have increased the development of PCLC medical devices. PCLCs shift specific assignments of data interpretation and therapy manipulation from a practitioner to a medical device. This may or may not introduce new risks to patients, but could introduce new medical device hazards that, considered during design and development, can be mitigated throughout the device life-cycle. Addressing technical and clinical challenges for a PCLC medical device to be robust, stable, and effective in its environment of use will ensure patient safety and promote innovation and development of PCLC medical devices.
This workshop seeks to involve industry, academia, medical societies, patient groups, standard bodies, and other relevant stakeholders in addressing the challenges in the development and implementation of PCLC medical devices in critical care environments. Participants in the workshop will include scientists and engineers developing PCLC medical devices, as well as end users including physicians, nurses, and patients. The intent of the workshop is to discuss benefit-risk considerations, design strategies, pre-clinical testing, and clinical evaluation for specific product areas of PCLC medical devices. Ideas generated during this workshop may facilitate development of new draft guidances and/or standards for PCLC medical devices.

5. Clinical evaluation (e.g., study design, clinical endpoints, outside the U.S. data)
a. Clinical validity of sensors
b. Patient populations
c. Environments of use
