Pain Paid Clinical Trials in California

This is a Phase 2, prospective, randomized, double-blind, placebo-controlled, multi-center, single-dose, pharmacodynamic study designed to evaluate the efficacy and safety of the combination product (VNX001) versus placebo and its individual components (heparin sodium and lidocaine hydrochloride (HCl)) for the reduction of bladder pain in patients with interstitial cystitis (IC) / bladder pain syndrome (BPS), Who Have an Episode of Acute Bladder Pain of Moderate to Severe Intensity.

The purpose of this study is to evaluate the efficacy, safety, and tolerability of VX-993 in participants with pain associated with Diabetic Peripheral Neuropathy (DPN) Read Less

The investigators are testing treatment with low-dose naltrexone (LDN) for symptom relief of complex regional pain syndrome (CRPS). Study participants will be randomly assigned to receive either LDN or placebo for a period of several weeks. During this period participants will be asked to attend either in-person or virtual study visits and complete questionnaires. Read Less

The Virus in Endodontics (VE) phase I pilot study for preoperative pain will be analyzed and adjusted for the Phase II clinical trial. The Phase II clinical trial on preoperative pain, postoperative pain, and clinical healing will involve 250 patients. Patients will be recruited from the same pool of participants as the Phase II clinical trial. Preoperative cone beam computed tomography (CBCT) scans will be taken as well as three and six month postoperative CBCT scans. The secondary outcomes form the Phase II randomized clinical trial will be clinical success and visible radiographic healing determined by CBCT images. Read Less

The purpose of this trial is to investigate the efficacy and safety of dapansutrile (OLT1177®) tablets in subjects with an acute gout flare. Read Less

The purpose of this study is to evaluate how safe and how well a treatment works compared to placebo for people with nerve pain that begins in their feet and moves up the leg to just below the knee. Participation may last up to 30 weeks including screening. Read Less

The purpose of the chronic pain master protocol is to compare independent pain interventions and establish an overarching structure for the disease-state addenda (DSA) and intervention-specific appendices (ISAs). The ISAs may start independently of other ISAs as interventions become available for clinical testing. Read Less

The goal of this experimental study is to understand if endotracheal tube (ETT) suctioning increases pain and causes stress on the body in intubated adult ICU patients. These patients are already on ventilators, which means they need suctioning to keep their airways clear, but this procedure may be uncomfortable and cause stress. The main questions this study aims to answer are: Does ETT suctioning raise pain levels as measured by the Critical-Care Pain Observation Tool (CPOT)? Does ETT suctioning increase certain chemicals in the blood (hypoxanthine, xanthine, and uric acid) that show stress and lack of oxygen in the body? Researchers will compare patients who have ETT suctioning (intervention group) with those who do not have suctioning during the study period (control group) to see if there are differences in pain and blood markers of stress. Participants will: Have pain measured before and after suctioning using the CPOT. Have blood samples taken from an existing line at three time points: 5 minutes before, 5 minutes after, and 30 minutes after suctioning. Provide demographic information (like age, gender, and diagnosis) from medical records. This research will help improve how pain is managed for ICU patients who cannot speak for themselves, potentially leading to better pain relief methods in the future. Read Less

VETERANS ONLY. Chronic low back pain (cLBP) is common. Most Americans will have at least one episode of low back pain in their lifetimes. Approximately 50% of all US Veterans have chronic pain, and CLBP is the most common type of pain in this population. This study will use a sequential randomized, pragmatic, 2-step comparative effectiveness study design. The main goal is to identify the best approach for treating cLBP using commonly recommended non-surgical and non-pharmacological options. The first step compares continued care and active monitoring (CCAM) to internet-based pain self-management (Pain EASE) and an enhanced physical therapy intervention that combines Pain EASE with tailored exercise and physical activity. Patients who do not have a significant decrease in pain interference (a functional outcome) in Step 1 and those desiring additional treatment will be randomized in Step 2 to yoga, spinal manipulation therapy (SMT), or therapist-delivered cognitive behavioral therapy (CBT). Participants proceeding to randomization in Step 2 will be allowed to exclude up to one of the three Step 2 treatments based on their preferences. The investigators' primary hypothesis for the first treatment step is that an enhanced physical therapy intervention that combines pain self-management education with a tailored exercise program will reduce pain interference greater than internet-based pain self-management alone or CCAM in Veterans with cLBP. The primary outcome is change in pain interference at 3 months, measured using the Brief Pain Inventory (BPI) pain interference subscale. Study participants will be followed for one year after initiation of their final study treatments to assess the durability of treatment effects. The study plans to randomize 2529 patients across 20 centers. Read Less

The goal of this clinical trial is to compare ketamine to a placebo when given as a single infusion during IV sedation in adults with chronic pain and depression. We do not know whether ketamine will be more effective than placebo under these circumstances. This study aims to: * Evaluate whether placebo is non-inferior to ketamine in treating chronic pain and depression, when delivered under propofol sedation * Confirm that propofol sedation is a safe way to keep participants blinded to treatment * Assess patients' comfort with the sedation process to improve future studies * Explore whether patient expectations affects their pain and depression Participants will: * Need to qualify for the study based on stringent medical criteria * Undergo sedation with propofol * Randomly receive either a ketamine or a placebo (saline) infusion during sedation * Complete several study assessments over 5-7 weeks Read Less

The purpose of this study is to evaluate the efficacy, safety, and tolerability of Suzetrigine (SUZ) in participants with pain associated with diabetic peripheral neuropathy (DPN). Read Less
