Patients with clonal cytopenia of undetermined significance (CCUS) and lower-risk myelodysplastic syndromes (MDS) have a life expectancy of 5 to 10 years. Mortality in these patients results from progression of disease to higher-risk MDS or acute myeloid leukemia (AML) and cardiovascular events. Currently there are no FDA-approved treatments with the potential to improve survival of patients with CCUS and lower-risk MDS. Statins are an appealing class of drugs to consider in this situation as preclinical data support their potential to suppress progression of myeloid malignancy, and they have a well-established role in prevention of major cardiovascular events. This is a pilot study to explore the role of statins in treatment of patients with CCUS and lower-risk MDS. In this study, change in inflammatory biomarkers and variant allele frequency (VAF) of somatic mutations will be used as a surrogate marker of response to statin therapy. The hypothesis is that the use of statins at diagnosis of CCUS or lower-risk MDS will reduce inflammation and delay or prevent the expected increase in the VAF of somatic mutations over time.

Chronic intracalvarial cortical stimulation is a minimally invasive method involving the neurosurgical placement of an electrode above the inner table of the skull. Over time, intracalvarial cortical stimulation is intermittently activated to modulate locally and distally connected brain regions. Because of the important role played by the dorsolateral prefrontal cortex in mood regulation, the goal of this study is to apply intracalvarial prefrontal cortical stimulation (IpCS) over the dorsolateral prefrontal cortex in severely treatment-resistant depressed (TRD) patients. Per the DSM-V and Centre for Medicare and Medicaid Services (CMS) nomenclatures, TRD patients are commonly defined as those whose treatment failed to produce response or remission after 2 or more attempts of sufficient duration and treatment dose. In the investigator's study, eligible TRD subjects will have a diagnosis of major depressive disorder with a suboptimal response to an adequate dose and duration of at least two different antidepressant treatment categories. These subjects will also have had exposure and transiently (non-durably) responded to non-invasive neurostimulation. The investigator anticipates that severely Treatment Resistant Depressed (TRD) Subjects with IpCS of the dorsolateral prefrontal cortex will show a significant decrease in depression symptoms as measured by the Montgomery-Asberg Depression Rating Scale (MADRS) at four months post-implant when compared to baseline. The investigator will enroll up to 20 subjects with severe refractory depression in an open trial, followed for up to one year. Depressive and cognitive symptoms will be rated periodically to assess the safety and efficacy of this procedure.

Upon successful screening and registration, enrollment to durvalumab monotherapy (cohort 1) will begin. If DLT criteria outlined in the protocol are exceeded with durvalumab monotherapy (cohort 1), the study will close. Provided the safety of durvalumab monotherapy is established, enrollment to combination regimen cohorts will proceed. Cohorts will simultaneously enroll in parallel to each other with patients assigned to cohorts based on patient slot availability and study site choice of radiation arm participation. Patient assignment to future phase 1 arms would proceed similarly. Within BCG-containing cohorts, treatment will begin at full-dose BCG. If DLT criteria outlined in Section 5.1.4 are exceeded with full-dose BCG, a one level dose reduction of BCG will be implemented. If DLT criteria outlined in Section 5.1.4 are exceeded with reduced-dose BCG, the BCG-containing cohort will not proceed to Phase 2 of the study. Similarly, if DLT criteria outlined in Section 5.1.4 are exceeded within non-BCG containing cohorts, the non-BCG containing cohort will not proceed to phase 2 of the study. Due to the prolonged half-life of antibody therapies, no dose adjustments are planned for durvalumab in any of the cohorts.

The goal of this study is to evaluate the feasibility and preliminary efficacy of an artificial intelligence (AI)-generated personalized question prompt list (a list of suggested questions to ask during outpatient appointments) for patients with hematologic cancers. The intervention will involve tailoring a standardized prompt to patients' individual characteristics and concerns. This prompt will then be used to ask Washington University's (WashU) HIPAA compliant ChatGPT to generate personalized question lists for outpatient appointments. Analyses will assess the impact of personalized QPLs on patients' question-asking behavior; communicative self-efficacy; and self-reported amount and satisfaction with information obtained about their disease and its treatment. Sub-analyses will explore patterns in questions generated by WashU ChatGPT. Patients will also provide feedback pertaining to the perceived helpfulness and ease-of-use of WashU-ChatGPT-generated question lists, as well as their attitudes and intentions regarding use of AI chatbots and whether they would engage in pre-appointment AI-assisted question brainstorming independently in the future.

This phase III trial compares the effect of adding cetuximab to pembrolizumab versus pembrolizumab alone in treating patients with head and neck squamous cell carcinoma (HNSCC) that has come back after a period of improvement (recurrent) and/or that has spread from where it first started (primary site) to other places in the body (metastatic). Cetuximab is in a class of medications called monoclonal antibodies. It binds to a protein called EGFR, which is found on some types of tumor cells. This may help keep tumor cells from growing. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the tumor, and may interfere with the ability of tumor cells to grow and spread. Giving cetuximab and pembrolizumab together may be more effective at treating patients with recurrent and/or metastatic HNSCC than pembrolizumab alone.

Kaposi sarcoma (KS) lesions are initiated by endothelial cells infected with KS herpesvirus (KSHV), also known as human herpesvirus 8 (HHV-8). Lesion progression is driven by abnormal angiogenesis, chronic inflammation, and uncontrolled cell proliferation. KS remains one of the most commonly diagnosed cancers in many African countries where economic constraints prevent successful treatment in most patients. Treatment outcomes in developed countries are also often unsatisfactory in HIV positive patients despite good virological and immunological responses to antiretroviral therapy. Therefore, identification of new oral, safe treatment options for treatment of KS remains a research priority. Given the known anti-angiogenic properties and based on the treatment response with other benign vascular lesions such as infantile hemangioma, propranolol is a good candidate for the treatment of KS. The hypothesis of this study is that treating patients with Kaposi sarcoma with propranolol will result in an overall response rate (complete response rate plus partial response rate) of at least 45%, and that propranolol will be safe and well tolerated in this patient population.
