5. Study Description

Brief Summary
This research study is for participants that have been diagnosed with intractable Obsessive -compulsive disorder (OCD). OCD is a persistent and oftentimes disabling disorder marked by unwanted and distressing thoughts (obsessions) and irresistible repetitive behaviors. OCD affects 2-3% of the US population, and is responsible for substantial functional impairment and increased risk of early death. The only established first-line treatments for OCD are cognitive-behavioral therapy (CBT) with exposure/response prevention and certain medications. About 30-40% of patients fail to respond and few experience complete symptom resolution. Up to 25% of patients have difficulty tolerating CBT and the risk of relapse after therapies remains large. For the most severe cases, neurosurgery (surgery in the brain), has long been the option of last resort. In this study the investigators want develop an adaptive Deep Brain Stimulation (aDBS) system to use in subjects with intractable (hard to control) OCD. Deep brain stimulation remains investigational for OCD patients and is not considered standard therapy. DBS involves the surgical implantation of leads and electrodes into specific areas of the brain, which are thought to influence the disease. A pack implanted in the chest, called the neurotransmitter, keeps the electrical current coursing to the brain through a wire that connects the neurotransmitter and electrodes. It is believed deep brain stimulation may restore balance to dysfunctional brain circuitry implicated in OCD. The goal of this study is to enhance current approaches to DBS targeting in the brain and to use a novel approach to find a better and more reliable system for OCD treatment. This current research protocol will focus on the completion of Phase Ib which will implant the RC+S system in 2 subjects.
Detailed Description
ENROLLMENT: A subject is considered enrolled upon signing informed consent, deemed eligible to be screened by the investigator. The informed consent process may include discussions with the patient¿s family and referring clinician. Medical records that can be obtained will be carefully reviewed to determine adequacy of past treatments including Cognitive Behavioral Therapy (CBT). A subject identification number will be assigned to each subject that signs consent. This number will be used to identify the subject and must be used on all study documentation related to that subject throughout the study. SCREENING: Potential subjects meeting inclusion/exclusion criteria and willing to participate in the study as demonstrated by signing the informed consent will be enrolled in the study and undergo 2 screening visits (Visit 1 and Visit 2) spaced over an approximate 1 month period. Diagnostic and screening ratings are completed, followed by complete medical, neurological and neurosurgical evaluations. Final selection of candidates will be made by consensus of the multi-disciplinary investigator team (Project Advisory Committee). Neuroimaging Methods: DBS implanted subjects will undergo 2- 3T MRI Scans prior to surgery (1 research MRI at CAMRI and 1 clinical MRI at BSLMC). DBS implanted subjects will under 3 MEGs total. Control subjects will undergo 1- 3T MRI scan (research MRI scan at CAMRI). Control subjects will also undergo 3 MEG scans. The Center for Advanced MR Imaging (CAMRI) at the Main Campus location of Baylor College of will perform the research 3T MRI scans, which will only be collected on all subjects (DBS and control) using the Prisma scanner on this project for consistency. TREATMENT: Subjects eligible for DBS implantation will also have an additional clinical, pre-surgical 3T MRI scan performed at baseline. This scan will be performed on a Philips scanner at Baylor St. Luke's Medical Center (BSLMC). This scan is necessary in order to potentially screen out individuals presenting with brain abnormalities which would not be compatible with the surgery (e.g., congenital defects, lack of normal anatomic correlates) and to assist with surgical planning. All Subjects (DBS and control) will also undergo MEG scans. This is also needed as a baseline assessment as MEG scans will also be performed post implantation at 2 weeks and 6 months. These scans will be performed on a MEG scanner at the Texas Children¿s Hospital in the Houston Medical Center. Chest X-ray and EKG will also be performed. Age/gender matched non-implanted subjects will serve as controls. They will undergo 1-research 3T MRI and 3 MEG scans using the same imaging protocol and at the same time points as OCD implant subjects to control for non-DBS effects on rs-fc. TREATMENT: Unless collected prior to the day of surgery, A a head CT will be performed on the morning of surgery for stereotactic planning. Employing local anesthetic (with or without sedation as clinically indicated), a stereotactic headframe (Leksell Model G, Elekta Instruments, Atlanta, GA, USA) will be attached to the subject¿s skull on the morning of surgery in the operating room. A 3D volumetric image (O-Arm 2, Medtronic Inc, Boulder, CO, USA) will be performed for purposes of defining the volumetric stereotactic headspace. The images will be uploaded onto a Computer Workstation (Stealth S7, Medtronic, Inc., Boulder, CO, USA) equipped with stereotactic planning software (Cranial 3.0) for the purpose of planning the surgery. The preoperative 3T MRI obtained prior to the surgical date, will be fused with the CT scan in the surgical planning station. The initial target point within the ventral striatum will be chosen based on the subject¿s specific anatomy. The surgical trajectory to this point will also be planned in order to avoid prominent vessels, the sulci, and the ventricles. The computer will generate the X, Y and Z coordinates to set on the frame as well as the coronal and sagittal angles of approach required to establish the desired trajectory and target point. This initial target point will be modified by the subject¿s specific anatomy as determined by the preoperative 3T scan. The final target coordinates will be determined during this analysis. While the surgeon is planning the procedure, the subject will be positioned supine on the operating table. A Foley catheter will be inserted. Antibiotics will be administered intravenously and vital signs will be monitored. The stereotactic head frame will be fixed to the operating table for subject safety, with the head elevated for subject comfort. A sterile prep and drape will be performed. The target coordinates will be set on the stereotactic frame bringing the target point to the center of the operating arc. Additional local anesthetic will be given at the point of incision. Following incision, a 14 mm burr hole will be made employing a self-stopping perforator. The burr hole cap provided with the DBS lead will be secured to the skull with two screws. The dura will be coagulated and incised. The pial surface will be gently coagulated and a small incision will be made to allow easy entry of the electrode guides, which will be inserted to the brain according to standard stereotactic protocol. A microelectrode (MER) probe will be inserted through the cannula and advanced in sub mm steps until the target is reached. Intraoperative image guidance will be obtained to ensure the MER probe is not mechanically deviated from target. If a deviation is identified, the stereotactic headframe will be adjusted accordingly. Once the above adjustments have been made, the DBS quadripolar electrode (model 3387; Medtronic Inc., Minneapolis, MN, USA) will be inserted through the guide tube to the target point. Reticles will be attached to the frame and intraoperative imaging will be employed to confirm that the lead tip is positioned at the target and assess for the presence of intracerebral hemorrhage. Sedation will be withdrawn. An extension cable will be connected to the lead sterilely and the other end will be passed off the field to be connected to an external pulse generator so that test stimulation may be performed. Test stimulation will be performed via each contact to 1) assess for stimulation-induced side effects and 2) monitor for acute changes in behavior using a Likert-type scale to assess anxiety, arousal, and mood. Intra operative behavioral testing of stimulation will be videotaped Intra-operative X-ray imaging may be performed as needed (up to 4 times per side) to ensure proper target has been reached. A post-implantation 3D volumetric scan will be performed to confirm the electrode position. Steps 5-9 above will be performed to insert the second electrode on the other side of the brain to complete implantation of both electrodes. If there are no untenable side effects, the leads will be secured to the skull with the burr hole caps. The free end of the leads will be left in the sub-galeal space and the incisions will be closed in anatomical layers. The headframe will be removed and general anesthesia will be induced. The Olympus RC+S pulse generator will then be implanted and connected to the brain lead via extension cables. A post-operative CT scan will be performed prior to discharge to ensure that an intracerebral hemorrhage has not occurred. The subject will be taken to the Recovery Room or the Neurosurgery ICU for post-operative monitoring (See below) and will be discharged from the hospital after at least one night of observation and when clinically stable. A Basic Metabolic Panel (BMP) may be run on the subject to confirm they are clinically stable. The subject will return to the neurosurgery clinic (Visit 4) for post-operative evaluation according to normal clinical practice (approximately 1 week after surgery). The wounds will be inspected and the subjects neurological status will be assessed. Sutures will be removed. Subjects will be asked to keep their current medications constant for the first 6 months post-surgery, but clinical circumstances which mandate changes will be allowed and notated should this occur. DBS Programming: Initially, a monopolar survey will be conducted with frequency set to 130 Hz and pulse width to 90 microseconds. Constant current amplitude will be used and increased in a step-wise fashion as tolerated and without exceeding current density upper limits. The constant current setting is particularly useful in the early weeks to months following surgery when impedances are still changing. In order to elicit a mirth response, amplitude needs to return to 0 microamps for about 30 seconds before testing the next increment. For example, if 2mA, C+1, 90usec, 130Hz is ineffective, then amplitude is reduced to 0mA for 30 seconds and then rapidly increased to 4mA, C+1-, 90usec, 130Hz. Soft start needs to be turned off. Bipolar settings will also be tested and need to be used during rsfMRI. DBS parameters will be optimized/adjusted based on clinical evaluation of mood and anxiety and to minimize side effects. The following observed effects will be recorded via a scale used in a past study: facial expression, nervousness, alertness, and positive or negative affect. Facial expression will be measured using the AFAR system. AFAR will measure the maximum intensity and velocity of the smile response in action units. Participants¿ faces will be recorded on video as their stimulation is increased to elicit the mirth response. Changes in facial expression using facial muscles of orbicularis oris (muscle that encircles the mouth) zygomaticus (major and minor muscles of the angle of the mouth) will be recorded. This information will be used to train a classifier to recognize that stimulation intensity is too great. The investigators will also have the subject self-report on changes in mood, anxiety, energy and side effects.
