This study is for subjects with Diffuse large B-cell lymphoma (DLBCL) that has gotten worse or come back after two or more treatments. This study is testing an "investigational" (not yet FDA approved drug) study drug called loncastuximab tesirine (ADCT-402). Treatment will be administered intravenously or via tablet depending on the subject's assigned treatment. The primary purpose of this study is to test whether the investigational drug combination of loncastuximab tesirine in combination with one of four other anti-cancer agents is a safe and effective treatment for relapsed or refractory B-cell Non-Hodgkin Lymphoma. Treatment will be assigned by a system in a sequence unless the subject has received the combination drug (the drug that is not locastuximab). This means the first enrolled subject will be assigned to arm C, the second to arm E, and so on. The subject will be seen approximately once a week during treatment, and may remain in the study for up to 3 years.

This study is for subjects that have been diagnosed with advanced solid cancer tumors or relapsed prostate cancer. The investigational drugs in this study are hydroxychloroquine, nelfinavir, metformin, dasatinib and sirolimus. The purpose of this study is to determine the safety and effectiveness of up to 5 study drugs used together for the treatment of cancer. Subjects can expect to be in this study for about 2.5 years.

This study is for patients who have advanced cancers, such as head and neck cancer, colorectal cancer, breast cancer, and others. This study is testing a new treatment for these types of cancer. The new test drug is called BCA101. Pembrolizumab is an approved drug by the United States Food and Drug Administration (FDA) for the diseases described in this study and will be used as approved. The type of cancer a patient has will determine whether he/she will get BCA101 alone or BCA101 in combination with pembrolizumab. Participants will receive either BCA101 alone, BCA101 in combination with pembrolizumab or BCA101 and enforafenib, depending on your cancer until the cancer gets worse, they experience bad side effects, or until they withdraw consent, or until the Investigator considers it is in his/her best interest to discontinue the study drug.

This study will repurpose medications that have already been approved for use by the Food and Drug Administration (FDA) for other indications to treat non-hospitalized patients that are at least 30 years old with mild to moderate COVID-19. The effectiveness of reducing COVID-19 symptoms will be evaluated by comparing the medication to a placebo or fake treatment with no therapeutic value. Participation will last about 180-days and all study visits are designed to be performed over the phone or remotely. Participants will be compensated for their time and participation in this research study.

This study is for subjects that have been diagnosed with diffuse large B-cell lymphoma (DLBCL), a type of non-Hodgkin lymphoma (NHL) that has gotten worse or come back after treatment. This study is testing an "investigational" (not yet FDA approved) study drug called Loncastuximab Tesirine. The primary purpose of this study is to evaluate the efficacy of loncastuximab tesirine combined with rituximab compared to standard immunochemotherapy. The subject may remain in the study for up to 5 years, 28 days for screening period, a 16-25 week treatment period, and a follow-up period of 4 years.

This study is for patients who have been diagnosed with relapsed (came back) and/or refractory (not responding to treatment) large B-cell lymphoma (LBCL). The investigational product is Lisocabtagene Maraleucel and is administered by infusion. Participants will have had the blood collection (leukapheresis - a laboratory procedure where white blood cells are separated from a sample of blood) procedure, where the T cells (white blood cells) were collected and genetically modified in a laboratory in order to manufacture the lisocabtagene maraleucel T cells for disease treatment. The lisocabtagene maraleucel T cells that were produced do not meet all of the prespecified release criteria to be used as a routine prescription drug as required by the Food and Drug Administration (FDA). This is called a nonconforming lisocabtagene maraleucel. The purpose of this study is to allow participants to be treated with their nonconforming lisocabtagene maraleucel. Participants can expect to be on the study for up to 3 months following the infusion of nonconforming lisocabtagene maraleucel.
