A multicenter, randomized, adaptive allocation clinical trial to determine if increasing durations of induced hypothermia are associated with an increasing rate of good neurological outcomes and to identify the optimal duration of induced hypothermia for neuroprotection in comatose survivors of cardiac arrest.

This phase III trial compares the effect of open thoracic surgery (thoracotomy) to thoracoscopic surgery (video-assisted thoracoscopic surgery or VATS) in treating patients with osteosarcoma that has spread to the lung (pulmonary metastases). Open thoracic surgery is a type of surgery done through a single larger incision (like a large cut) that goes between the ribs, opens up the chest, and removes the cancer. Thoracoscopy is a type of chest surgery where the doctor makes several small incisions and uses a small camera to help with removing the cancer. This trial is being done evaluate the two different surgery methods for patients with osteosarcoma that has spread to the lung to find out which is better.

This phase I/II trial tests the safety, side effects, and best dose of selinexor given in combination with standard radiation therapy in treating children and young adults with newly diagnosed diffuse intrinsic pontine glioma (DIPG) or high-grade glioma (HGG) with a genetic change called H3 K27M mutation. It also tests whether combination of selinexor and standard radiation therapy works to shrink tumors in this patient population. Glioma is a type of cancer that occurs in the brain or spine. Glioma is considered high risk (or high-grade) when it is growing and spreading quickly. The term, risk, refers to the chance of the cancer coming back after treatment. DIPG is a subtype of HGG that grows in the pons (a part of the brainstem that controls functions like breathing, swallowing, speaking, and eye movements). This trial has two parts. The only difference in treatment between the two parts is that some subjects treated in Part 1 may receive a different dose of selinexor than the subjects treated in Part 2. In Part 1 (also called the Dose-Finding Phase), investigators want to determine the dose of selinexor that can be given without causing side effects that are too severe. This dose is called the maximum tolerated dose (MTD). In Part 2 (also called the Efficacy Phase), investigators want to find out how effective the MTD of selinexor is against HGG or DIPG. Selinexor blocks a protein called CRM1, which may help keep cancer cells from growing and may kill them. It is a type of small molecule inhibitor called selective inhibitors of nuclear export (SINE). Radiation therapy uses high energy to kill tumor cells and shrink tumors. The combination of selinexor and radiation therapy may be effective in treating patients with newly-diagnosed DIPG and H3 K27M-Mutant HGG.

A study of sevasemten (EDG-5506) in Becker muscular dystrophy (known as CANYON) and pivotal cohort (known as GRAND CANYON). The EDG-5506-201 CANYON study was expanded to include an additional 120 adult participants in a cohort called GRAND CANYON, that is a multicenter, randomized, double-blind, placebo-controlled study to evaluate the safety and efficacy of sevasemten in adults with Becker.

CANYON is fully enrolled; GRAND CANYON is currently enrolling.

HOPE-3 is a two cohort, Phase 3, multi-center, randomized, double-blind, placebo-controlled clinical trial evaluating the efficacy and safety of a cell therapy called deramiocel (CAP-1002) in study participants with Duchenne muscular dystrophy (DMD) and impaired skeletal muscle function. Non-ambulatory and ambulatory boys and young men who meet eligibility criteria will be randomly assigned to receive either deramiocel or placebo every 3 months for a total of 4 doses during the first 12 months of the study. All participants will be eligible to receive 4 doses of deramiocel for an additional 12 months as part of an open-label extended assessment period. After completion of the first open-label extension (Months 12-24), subjects who have completed Month 24 are eligible to continue onto a Long-Term Open-Label Extension period that will provide treatment with deramiocel until commercial availability, or until sponsor's decision to terminate the trial, or the participant withdraws consent.

This Phase 3 trial (Study SRK-015-003) was conducted in patients ≥2 years old at Screening, who were previously diagnosed with later-onset spinal muscular atrophy (SMA) (i.e., Type 2 and Type 3 SMA) and were receiving an approved survival motor neuron (SMN) upregulator therapy (i.e., either nusinersen or risdiplam), to confirm the efficacy and safety of apitegromab as an adjunctive therapy to nusinersen and evaluate the efficacy and safety of apitegromab as an adjunctive therapy to risdiplam.

In this study, researchers will learn more about the use of a higher dose of nusinersen (BIIB058) in participants with spinal muscular atrophy (SMA). This study will focus on teenagers and adults who are unable to walk on their own and who have previously taken another drug for SMA called risdiplam.

The main goal of this study is to learn about the effect of high dose (HD) nusinersen on muscle and movement ability (motor function) in SMA. The main question that researchers want to answer is:

- How do the scores of a movement test called the Revised Upper Limb Module change from the start of treatment?

The Revised Upper Limb Module is a test used to measure a participant's ability to do specific tasks that involve their shoulders, arms, wrist, elbows, and hands. It measures the changes in their abilities over time.

Researchers will also learn more about the safety of HD nusinersen. They will check participants for adverse events and changes in vital signs, heart tests, and laboratory tests including blood and urine tests.

The study will be done as follows:

* Participants will be screened to check if they can join the study.
* After screening, participants will enter the Core Treatment period.
* At the start of the Core Treatment period, they will receive 2 "loading" doses of nusinersen. These are 50 mg doses of nusinersen given 2 weeks apart.
* Afterwards, they will continue to receive "maintenance" doses of nusinersen once every 4 months. These doses will be 28 mg.
* The Core Treatment period will last about 2 years, with a follow-up visit 4 months after the last dose.
* Participants who complete the Core Treatment period will have the option to continue receiving 28 mg of nusinersen in the Long-Term Extension (LTE) period for about 2 years. There will also be a follow-up visit 4 months after the last dose.
* Nusinersen will be given through a lumbar puncture, which involves injecting the drug into the fluid around the spinal cord in the lower back.
* In total, participants will have up to 18 study visits. They will also be called by researchers after each dose of nusinersen.
* Participants will stay in the study for about 4.5 years if they complete both the Core Treatment and LTE periods.

This is a Phase 2, multicenter, open-label, randomized, controlled study designed to evaluate the safety and efficacy of pegcetacoplan in patients who have post-transplant recurrence of C3G or IC-MPGN.

Long-term follow-up of subjects who received ST-920 in a previous trial (ST-920-201) and completed at least 52 weeks post-infusion follow-up in their primary protocol. Enrolled subjects will be followed for a total of up to 5 years following ST-920 infusion.
