The ALSTARS trial will be conducted across 20-25 sites in the US and Canada, and will evaluate the safety and efficacy of an investigational treatment called COYA 302 for adults with Amyotrophic Lateral Sclerosis (ALS). COYA 302 is an investigational and proprietary biologic combination therapy with a dual immunomodulatory mechanism of action intended to enhance the anti-inflammatory function of regulatory T cells (Tregs) and suppress the inflammation produced by activated monocytes and macrophages. It is comprised of low dose interleukin-2 (LD IL-2) and DRL_AB (a biosimilar candidate for abatacept). Participants will be randomly assigned to receive one of 2 regimens of COYA 302 or placebo (an inactive substance) in a 1:1:1 ratio for 24 weeks in the double-blind (DB) period. Those who complete this part of the study will be eligible to receive one of the two regimens of COYA 302 for an additional 24 weeks in a blinded active extension phase (EXT). The study will assess changes in disease progression using established ALS clinical outcome measures, including the ALS Functional Rating Scale-Revised (ALSFRS-R), neurofilament (NfL), maximal inspiratory pressure (MIP), slow vital capacity (SVC), and neurological assessments. Additional objectives include evaluation of biomarkers and safety through routine clinical assessments and adverse event monitoring.

The purpose of this research is to address the challenges of diagnosing and long-term management of epilepsy in participants whose seizures are not well captured by standard electroencephalography (EEG) tests and who cannot use or are not able to use more standard monitoring techniques. This research will compare the Minder System to standard of care in providing reliable seizure data. The Minder System was granted De Novo classification by the U.S. Food and Drug Administration (FDA) and is not investigational. Participants will consent to join the study and be implanted with the Minder device; or consent to join the study and continue with their Standard of Care (SOC) as a control group. Participants chose to be implanted with the Minder device will have the device implanted under their scalp. After implantation, participants will be randomly assigned to a group where their treating physician will have access to the EEG data collected by the Minder System or a group where their treating physician does not have access to the EEG data collected by the Minder System. Participants receiving the Minder System will not know which group they are in (blinded) until the study ends. All participants will continue to be followed by their treating physician and undergo assessments and visits until enough information is available to determine a treatment plan or the 6-month follow-up visit.

Some people with pancreatic ductal cancer (PDAC) have a protein called Claudin 18.2 (CLDN18.2) in their tumor. ASP2138 is thought to work by binding to CLDN18.2 and a protein on a type of immune cell called a T-cell. The T-cell "tells" the immune system to attack the tumor. This study is for people with resectable PDAC. Resectable means that the tumor can be removed by surgery. In this study, adults with resectable PDAC will receive an ASP2138 injection just below the skin (subcutaneous) 2 weeks before surgery. After surgery, they will be given standard chemotherapy treatments chosen by their study doctor. These include mFOLFIRINOX, gemcitabine with nab-paclitaxel, or gemcitabine with capecitabine. People will receive chemotherapy treatment for up to 6 months, or until their cancer gets worse, they cannot tolerate the chemotherapy, or they or their study doctor thinks they should stop chemotherapy. People will have a final clinic visit about a month after finishing chemotherapy for health checks.

This research aims to improve the management of exocrine pancreatic insufficiency (EPI), a condition that can develop after pancreatitis, a painful inflammation of the pancreas. EPI occurs when the pancreas does not produce enough enzymes to help the body properly digest food. While pancreatic enzyme replacement therapy (PERT) is commonly used to manage EPI symptoms, it can be challenging for people who rely on feeding tubes. RELiZORB, could help these patients by simplifying the delivery of the enzymes they need. However, RELiZORB has only been studied in people with EPI caused by cystic fibrosis, so its effectiveness in pancreatitis patients remains unknown. This study aims to determine whether RELiZORB is effective for individuals requiring feeding tube support after pancreatitis.

The goal of this randomized clinical trial is to learn if the use of a low-dose nonsteroidal anti-inflammatory drug (NSAID), ketorolac, reduces the rate of chronic opioid use in orthopaedic trauma patients. The main questions this study aims to answer are: 1. Are patients who are given scheduled ketorolac during the first five days of the perioperative period in combination with standard of care (SOC) multimodal analgesia (MMA) less likely to develop chronic opioid use at 6 months after injury compared to patients who SOC MMA alone? 2. Does scheduled ketorolac during the first five days of the perioperative period improve functional responses to pain at discharge, 3 months, and 6 months after injury? 3. Does early pain control provided by ketorolac decrease chronic opioid use through decreased acute pain and opioid use, improved functional responses to pain, or both? Participants will be enrolled and randomized to either the ketorolac (treatment) group or the SOC group. Patients randomized to the ketorolac group will receive ketorolac every 6 hours for up to five days during the perioperative period; patients discharged prior to completing the five-day regimen will complete the remainder of treatment with oral ketorolac. Pain and opioid use will be measured daily during the five-day treatment period. Opioid use will be measured and functional response to pain surveys will be obtained at discharge, 2 weeks, 6 weeks, 3 months, and 6 months after injury. Researchers will compare patients receiving ketorolac (treatment) plus SOC versus those receiving SOC alone to determine if ketorolac reduces chronic opioid use and improves the functional response to pain.

Crohn's Disease (CD) is a gastrointestinal disease that can cause chronic diarrhea with or without gross bleeding, abdominal pain, weight loss, and fever. This study will assess the pharmacokinetics, efficacy, and safety of risankizumab in pediatric participants with moderately to severely active CD aged 2 to < 18 years old who have had intolerance or inadequate response to other therapies. Risankizumab is an approved drug for adults with plaque psoriasis, psoriatic arthritis, and CD and is being developed for the treatment of CD in pediatrics. This study is comprised of 3 cohorts that may participate in 3 substudies (SS). Cohort 1 will enroll participants with ages from 6 to less than 18 years. Cohort 2 will enroll participants with ages from 2 to less than 6 years. Cohort 3 will enroll participants with ages from 2 to less than 18 years. SS1 is an open-label induction period where participants will receive a weight-based induction regimen of risankizumab. SS2 is a double-blind maintenance period where participants will be randomized to receive 1 of 2 doses of weight-based induction regimen of risankizumab. SS3 is an open-label extension period where participants will receive risankizumab based off of their response in SS2. Approximately 110 pediatric participants with CD will be enrolled at around 100 sites worldwide. Participants in SS1 will receive risankizumab intravenously during the 12-week induction period. Participants in SS2 will receive risankizumab subcutaneously during the 52-week randomized maintenance period. Participants in SS3 will receive risankizumab subcutaneously during the 208-week open label period. Participants will be followed-up for approximately 140 days. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.

This project aims to optimize a critical but understudied ingredient of language intervention provided to children with developmental language disorder (DLD) - feedback. The project will bridge a gap between previous findings in our lab of inefficient feedback processing in DLD and clinical practice by identifying the conditions under which feedback-based learning can be improved in DLD. The investigators hypothesize that the effectiveness of feedback can be significantly enhanced for children with DLD when it is tailored to their unique learning strengths. The rationale for this project is based on evidence that feedback-based learning can be improved by enhancing the dominance of an intact learning system. The project will achieve its aim by manipulating (1) the timing of the feedback (immediate vs. delayed) and (2) the level of the learner's involvement in error correction dictated by feedback (active vs. passive correction). Aim 1 will determine the effect of manipulating feedback timing on learning in 140 school-age children (8-12 years) with DLD. While immediate feedback is processed by the striatum, which is also implicated in implicit learning, delaying the feedback by a few seconds shifts feedback processing to the mediate temporal lobe (MTL)-based declarative learning system. Evidence that delaying feedback improves learning in DLD would support the hypothesis of the implicit deficit theory that intervention should capitalize on declarative learning mechanisms. The project will test a novel alternative feedback-learning parity hypothesis whereby feedback-based learning is optimized when the timing of the feedback is aligned with the dominant learning system at a given time (i.e., immediate feedback during striatal-based probabilistic learning; delayed feedback during MTL-based declarative learning). Within the same group of children, Aim 2 will compare feedback-based learning in children with DLD when feedback (a) prompts active self-correction or (b) passively exposes learners to error corrections (corrective recast). Children will engage in two nonword-object paired-associate learning tasks. In one task, feedback will promote active self-correction, which is in line with declarative learning. In the other task, feedback will passively expose the learner to corrective feedback in a manner consistent with teaching approaches aiming at reducing awareness of errors. The project will determine whether children with DLD learn better when feedback prompts self-correction or when they are exposed to passive corrections. Electrophysiological measures will indicate whether passive corrections (corrective recast) are processed as negative feedback by children with DLD. For both aims, behavioral indicators of response to feedback will be complemented by electrophysiological measures of feedback processing that can determine the involvement of the striatum and MTL brain systems during the learning process. This work is scientifically and clinically significant because elucidating what manipulations optimize feedback-based learning will enhance our understanding of the impaired learning mechanism in DLD and will provide clinical guidance on what type of feedback to use during an intervention.
