NCT04729959
This phase II trial studies the best dose and effect of tocilizumab in combination with atezolizumab and stereotactic radiation therapy in treating glioblastoma patients whose tumor has come back after initial treatment (recurrent). Tocilizumab is a monoclonal antibody that binds to receptors for a protein called interleukin-6 (IL-6), which is made by white blood cells and other cells in the body as well as certain types of cancer. This may help lower the body's immune response and reduce inflammation. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Fractionated stereotactic radiation therapy uses special equipment to precisely deliver multiple, smaller doses of radiation spread over several treatment sessions to the tumor. The goal of this study is to change a tumor that is unresponsive to cancer therapy into a more responsive one. Therapy with fractionated stereotactic radiotherapy in combination with tocilizumab may suppress the inhibitory effect of immune cells surrounding the tumor and consequently allow an immunotherapy treatment by atezolizumab to activate the immune response against the tumor. Combination therapy with tocilizumab, atezolizumab and fractionated stereotactic radiation therapy may shrink or stabilize the cancer better than radiation therapy alone in patients with recurrent glioblastoma.
NCT03263936

NCT05501262
Morton's neuroma is a benign thickening involving the plantar interdigital nerve, most common in middle aged women. Morton's neuroma is one of the most frequent diagnoses seen in the investigators podiatry clinic and is difficult to treat. These lesions cause a burning or shooting pain that can radiate to the toes, or an aching pain in the ball of the foot. The pain is exacerbated with activity and certain footwear greatly limits activity in the involved patient population. Morton's neuroma is first treated conservatively with orthotics. Patients may require further interventions such as steroid injections. The literature reports only a 30% long term resolution of pain with the steroid. Surgical resection has a reported 51-85% success rate with 14-21% rate of complication; recurrent pain, numbness/loss of sensation, and subsequent stump neuromas. Cryoablation is well known to be efficacious for neuropathic pain and has recently been shown in two small studies to be safe and efficacious for treatment of Morton's neuroma. The investigators study will compare outcomes of cryoablation to corticosteroid injection in short- and long-term for treatment of Morton's neuroma that have failed conservative therapy.
NCT05860959
This study will provide the opportunity to generate data on the long-term use of SUBLOCADE under real-world conditions, and to observe enduring changes in lifestyle, health, and sociodemographic factors that are part of the recovery process. Long-term patterns of abstinence/opioid misuse as well as measures of participants' physical, psychological, social, and economic well-being will be monitored to better understand factors associated with recovery from opioid use disorder (OUD). Therefore, this study will observe participants up to a maximum of 4 years.
NCT03022825
This is a Phase II/III, open-label, single-arm, multicenter study of intravesical BCG plus N-803 or N-803 only in patients with BCG unresponsive high grade non-muscle invasive bladder cancer (NMIBC). All patients treated in the study will receive via a urinary catheter in the bladder, BCG plus N-803 or N-803 only weekly for 6 consecutive weeks (initial induction treatment period). After the first disease assessment, eligible patients will receive either a 3-week maintenance course or a 6-week re-induction course (second treatment period) at Month 3. Eligible patients will continue to receive maintenance treatment in the third treatment period at Months 6, 9, 12, and 18. Eligible patients have the option to receive maintenance treatment in the fourth treatment period at Months 24, 30, and 36. The study duration is 60 months.

CT-AMT-130-01 is a Phase 1/2, multicenter, first-in-human (FIH) study. The first three cohorts of the study have completed enrollment, including the randomized, double-blind, sham-controlled cohorts. Cohort 4 is open-label. Cohort 4 participants will receive high dose AMT-130.
NCT02959437
This is an open-label, Phase 1/2 study in subjects with advanced or metastatic solid tumors. The study has three separate treatment groups where separate epigenetic agents are evaluated with an immunotherapy combination. Treatment Group A will evaluate the DNA methyltransferase inhibitor azacitidine in combination with the programmed death receptor-1 (PD-1) inhibitor pembrolizumab and the indoleamine 2,3-dioxygenase (IDO-1) inhibitor epacadostat; Treatment Group B will evaluate the bromodomain and extra-terminal (BET) inhibitor INCB057643 with pembrolizumab and epacadostat; and Treatment Group C will evaluate the lysine-specific demethylase 1A (LSD1) inhibitor INCB059872 with pembrolizumab and epacadostat. The study will be divided into 2 parts (Part 1 and 2). Part 1 is a dose-escalation assessment to evaluate the safety and tolerability of the combination therapies. Once the recommended doses have been determined, subjects with previously treated NSCLC, microsatellite-stable colorectal cancer (CRC), head and neck squamous cell carcinoma, urothelial carcinoma, and melanoma will be enrolled into expansion cohorts in Part 2.
NCT05866302
The study will have two separate patient cohorts: Cohort 1 will include patients with newly diagnosed chronic graft versus host disease (GVHD), whereas cohort 2 will include patients with newly diagnosed chronic lung disease (CLD). For cohort 1, the primary objective will be to characterize PRM metrics at the onset of chronic GVHD and determine if a PRM signature is present that will predict 1-year CLD free survival. For cohort 2, the primary objective will focus on characterizing PRM at the onset of CLD and determine if PRM can predict the trajectory in lung function decline in affected patients.
NCT04294927
The aim of the project is to evaluate the risk-reducing salpingectomy with delayed oophorectomy as an alternative for risk-reducing salpingo-oophorectomy in high risk women with respect to ovarian cancer incidence.
NCT03584516
The purpose of this study is to assess the efficacy and safety of itacitinib in combination with corticosteroids as first-line treatment for moderate or severe chronic graft-versus-host disease (cGVHD).
NCT02386553
The primary objective of the study is to examine the efficacy of multiple doses of Nusinersen administered intrathecally in preventing or delaying the need for respiratory intervention or death in infants with genetically diagnosed and presymptomatic spinal muscular atrophy (SMA). Secondary objectives of this study are to examine the effects of Nusinersen in infants with genetically diagnosed and presymptomatic SMA.
NCT05896163
The purpose of this study is to learn about the effects of two study medicines (maplirpacept \[PF-07901801\] and glofitamab) when given together for the treatment of diffuse large B-cell lymphoma (DLBCL) that is relapsed or is refractory. Relapsed means has returned after last treatment. Refractory means that it has not responded to last treatment. The two study medicines are given after a single dose of obinutuzumab which is the third study medicine. DLBCL is a type of non-Hodgkin lymphoma (NHL). NHL is a cancer of the lymphatic system. It develops when the body makes abnormal B lymphocytes. These lymphocytes are a type of white blood cell that normally help to fight infections. This study is seeking adult participants who: * Have histologically confirmed diagnosis of DLBCL * Have received at least two first lines of treatment for NHL. * Are unable or unwilling to undergo a stem cell transplant or CAR-T cell therapy. Stem cell transplant is a procedure in which a patient receives healthy blood-forming cells to replace their own stem cells that have been destroyed by treatment. A CAR-T therapy is a type of treatment in which a patient's T cells are changed in the laboratory so they will attack cancer cells. Everyone in this study will receive all three medicines at the study site by intravenous (IV) infusion which is given directly into a vein. The two study medicines (maplirpacept \[PF-07901801\] and glofitamab) will be given in 21-day cycles. At Cycle 0, participants will receive a single dose of obinutuzumab pre-treatment followed by two step-up doses of glofitamab. The combination of maplirpacept (PF-07901801) with glofitamab full dose will be administered for the first time at Cycle 1 Day 1. Maplirpacept (PF-07901801) will be given weekly for the first three cycles and then every three weeks. Glofitamab will be given every 3 weeks for approximately 9 months. Thereafter participants will continue to receive maplirpacept alone. Maplirpacept (PF-07901801) will be given at different doses to different participants. Everyone taking part will receive the same fixed doses of glofitamab and obinutuzumab studied in patients with DLBCL. The study will compare the experiences of people receiving different doses of maplirpacept (PF-07901801). This will help to determine what dose is safe and effective when given with the other 2 study medicines.
