This randomized phase II/III trial studies how well giving maintenance chemotherapy with or without local consolidation therapy works in treating patients with stage IV non-small cell lung cancer. Drugs used in maintenance chemotherapy, such as docetaxel, pemetrexed disodium, erlotinib hydrochloride, and gemcitabine work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Local consolidation therapy such as radiation/stereotactic body radiation or surgery may kill cancer cells left after initial treatment. Giving maintenance chemotherapy and local consolidation therapy together may work better than maintenance chemotherapy alone in treating patients with stage IV non-small cell lung cancer.

The overarching purpose of this study is to evaluate the clinical efficacy of an investigational agent, P10s-PADRE, a peptide mimotope-based vaccine, in combination with standard-of-care (SoC) treatment in subjects with advanced-stage (i.e., metastatic) Lung Cancer. Vaccine will consist of P10s-PADRE admixed with an adjuvant, MONTANIDETM ISA 51 VG. Up to one hundred fifty (150) subjects with advanced-stage Lung Cancer of any histologic type will be enrolled for this vaccine trial. This single-arm, multi-site trial is designed to evaluate the therapeutic benefits of the vaccine in subjects with advanced-stage lung cancer. The primary objectives of the study are: (1) to monitor the safety and tolerability of the vaccine when it is administered in combination with SoC therapy; and (2) to determine whether immunization with vaccine can successfully elicit a robust immune response in subjects with advanced-stage lung cancer.

This randomized phase III trial studies cabozantinib S-malate to see how well it works compared with placebo in treating patients with neuroendocrine tumors previously treated with everolimus that have spread to nearby tissues or lymph nodes, have spread to other places in the body, or cannot be removed by surgery. Cabozantinib S-malate is a chemotherapy drug known as a tyrosine kinase inhibitor, and it targets specific tyrosine kinase receptors, that when blocked, may slow tumor growth.

This phase II trial studies how well radiation therapy with or without apalutamide works in treating patients with stage III-IV prostate cancer. Radiation therapy uses high energy x-ray to kill tumor cells and shrink tumors. Androgen can cause the growth of prostate cancer cells. Drugs, such as apalutamide, may lessen the amount of androgen made by the body. Giving radiation therapy and apalutamide may work better at treating prostate cancer than radiation alone.

The purpose of this research study is to look at the effect of a treatment regimen called CACTUX on head and neck cancer. The CACTUX regimen is a combination of three drugs called cisplatin, nab-paclitaxel, and cetuximab (although carboplatin may be given in place of cisplatin if participants have previously had problems receiving cisplatin). The use of nab-paclitaxel in this combination is different from routine care, in which a drug called 5FU is often given instead, but the investigators group has conducted previous research where the investigators incorporated nab-paclitaxel into routine treatment with cisplatin, 5FU, and cetuximab. The investigators are looking at the incidence of side effects with the CACTUX regimen as well as response of the disease and health status.

This randomized phase II/III trial studies how well cediranib maleate and olaparib work when given together or separately, and compares them to standard chemotherapy in treating patients with ovarian, fallopian tube, or primary peritoneal cancer that has returned after receiving chemotherapy with drugs that contain platinum (platinum-resistant) or continued to grow while being treated with platinum-based chemotherapy drugs (platinum-refractory). Cediranib maleate and olaparib may stop the growth of tumor cells by blocking enzymes needed for cell growth. Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known whether giving cediranib maleate and olaparib together may cause more damage to cancer cells when compared to either drug alone or standard chemotherapy.

This is a randomized, double blind, active control study of PRX-102 (pegunigalsidase alfa) in Fabry disease patients with impaired renal function. Patients treated for approximately 1 year with agalsidase beta and on a stable dose for at least 6 months will be screened and then randomized to continue treatment with 1mg/kg agalsidase beta or to treatment with 1 mg/kg of PRX-102. The identity of the enzyme will be blinded to the patient and the investigator. Patients will receive intravenous infusions every two weeks. Patients will be randomized in a 2:1 ratio of PRX-102 to agalsidase beta. Randomization will be stratified by urinary protein to creatinine ratio (UPCR) of < or ≥ 1 g/g by spot urine sample. No more than 50% of the patients will be female.

The purpose of this study is to evaluate the level of a specific protein (PTEN) in the cancer cells of chronic myelomonocytic leukemia (CMML) patients. This protein might be involved in the transformation from normal blood cells to leukemia cells. The PTEN protein has not been investigated in CMML specifically but it has been discovered in closely related cancers. If this study demonstrates an abnormality in this protein, future testing will be designed to evaluate the genetic abnormality that resulted in lack of the normal presence of this protein. The goal is that the results of this study will help to develop new drugs and strategies to treat the future patients with CMML by understanding the abnormality of the disease at the cellular and molecular levels. The results of this study can also be utilized by future studies to develop individualized treatment to patients who have abnormal levels of this protein.

The purpose of this study is to further advancements in biospecimens (blood cellular free component, e.g., plasma, serum, tissue, urine), in order to develop precision medicine, for lung cancer management and lung cancer screening (synergy with imaging). A co-clinical trial approach, with integrative analyses leveraging data from the treatment of genetic mouse models of lung cancer along with clinical samples and data from lung cancer patients, will be used to elucidate genomic background metrics, identify cell free DNA mutations, and further refine the liquid biopsy approach. Blood and urine samples will be analyzed for different genetic components. The tissue biopsy will be implanted into a mouse and after the cancer grows in the mouse the cancer DNA from the mouse will be compared with the human blood.

Overall, this proposal seeks to improve treatment strategies for the significant public health problem of prescription opioid dependence by determining whether gabapentin, a non-narcotic pharmaceutical agent with minimal abuse potential and preliminary efficacy, will be effective in ameliorating withdrawal symptoms, craving and illicit drug use in prescription opioid dependent participants undergoing a 10-day detoxification from buprenorphine. In addition, the acceptability and feasibility of transitioning to depot naltrexone therapy will also be determined. If successful, this study would provide data to support further development of gabapentin as a pharmacological tool for improved outcomes during opioid detoxification as well as an integrated outpatient approach for treating prescription opioid dependence.
