1. A Study to Evaluate Thymoma Recurrence

   Rochester, Minn.

   The purpose of this study is to evaluate thymoma recurrence rates in patients who underwent thymectomy.

2. Cancer screening practices of individuals with Lynch Syndrome

   Rochester, Minn.

   This is a survey study to describe how women with Lynch syndrome are being screened for gynecologic cancer risk, their perception of cancer risk, and uptake of risk reducing surgery.

3. Brain Tumor Repository

   Scottsdale/Phoenix, Ariz.

   The main objective of the Brain Tumor Repository is to allow access to coded patient data by researchers both inside and outside of the Mayo Clinic system so that important research questions can be answered. 

4. A Study to Assess Endometrial Cancer Recurrence in Patients After 36 Months

   Rochester, Minn.

   The purpose of this study is to assess the 36-month incidence of pelvic/non-vaginal recurrence among patients with surgical stage I intermediate-risk endometrial cancer.

   Eligible patients presenting with apparent uterine confined grade 1, 2, or 3 endometrioid endometrial cancer will undergo standard-of-care primary surgical treatment with a cervical injection of indocyanine green (ICG) dye for SLN mapping, a total hysterectomy, removal of the adnexae and staging with sentinel node mapping and pelvic washings. 

   The final assessment for inclusion in the follow-up part of the study will be determined from the results of the final hysterectomy and staging pathology report to ensure bilaterally negative pelvic sentinel nodes and a surgical stage I endometrioid endometrial cancer grade 1 or 2 with 50% or more uterine myoinvasion or grade 3 with less than 50% uterine myoinvasion. Women meeting this criteria will comprise the study cohort and be followed for three years.   

    

5. Niraparib in Combination With Trastuzumab in Metastatic HER2+ Breast Cancer

   Rochester, Minn.

   The purpose of this study is to evaluate a new treatment using a potent Poly polymerase (PARP) inhibitor known as Niraparib. Niraparib will be combined with trastuzumab, a HER2-targeted agent, to evaluate the safety and tolerability in patients with metastatic HER2 positive breast cancer. It is anticipated that the combination of drugs will improve survival and have few side effects.

   The human epidermal growth factor receptor 2 (HER2) regulates cell growth and survival. Approximately 15-20% of all breast cancers are HER2-positive, which are an aggressive and fast-growing subtype of breast cancer.

6. Study of Tumor-treating Fields to Treat Leptomeningeal Metastases from Breast Carcinoma Involving the Spine

   Jacksonville, Fla.

   The purpose of this study is to evaluate the safety and feasibility of the spinal array in treatment of patients with leptomeningeal metastases within the spine

   The median survival of patients with LM with treatment is generally less than 5 months. There are four FDA-approved drugs for intra-CSF use in LM, but all have shown limited activity with no clear increase in survival outcome with treatment. Intra-CSF treatment is also invasive, involving either surgical placement of an intraventricular reservoir, or treatment (intrathecal) via repetitive lumbar punctures, and there is risk of adverse events including vomiting, headache, arachnoiditis and leukoencephalopathy with treatment. Systemic chemotherapy, targeted agents and immunotherapy have largely been ineffective in treatment of LM, in part due to limited CNS/CSF penetration. New effective treatments are needed.

   TTF represents a new modality that is well tolerated with minimal adverse events. TTF has not produced significant additive toxicity when combined with systemic treatments. In addition, no invasive procedures are required, and treatment has been administered for long term without apparent cumulative toxicities.  TTF is currently approved for treatment of glioblastoma and mesothelioma. TTF is currently under study for treatment of CNS parenchymal metastases, lung and pancreatic cancer. There is potential application for symptomatic treatment of LM and intradural, extradural and vertebral metastases. Given the lack of effective therapies for LM, TTF is a promising alternative modality that should be explored. In addition, the lack of overlapping toxicities would potentially allow the use of TTFields in conjunction with other ongoing treatments for the leptomeningeal or systemic cancer. For these reasons, we are proposing an exploratory, phase I feasibility study of TTFields in treatment of the spinal component of leptomeningeal metastases, If feasible, consideration will be given to expansion to a Phase 1/2 study in a selected cohort of patient with LM.  

7. A Study to Evaluate MRTX849 in Patients with Advanced Solid Tumors with KRAS G12C Mutation

   Rochester, Minn., Jacksonville, Fla., Scottsdale/Phoenix, Ariz.

   The purpose of this study is to characterize the safety and tolerability of MRTX849 in patients having advanced solid tumor malignancies with KRAS G12C mutation.

8. A Study of Proton Versus Photon Beam Radiotherapy in the Treatment of Unilateral Head and Neck Cancer

   Rochester, Minn.

   Compared to IMRT, PBRT is thought to give less radiation exposure to the surrounding healthy tissues. It is possible that side effect rates with PBRT will be lower or the same compared to IMRT, but this has not been well studied to date. Although both of these radiation therapies have been used in the past to treat head and neck cancer, this research study will compare the effects of these two different radiation treatment modalities with each other to see whether PBRT is better, the same or worse than IMRT.

9. Study of Adjuvant Cemiplimab Versus Placebo After Surgery and Radiation Therapy in Patients With High Risk Cutaneous Squamous Cell Carcinoma

   Scottsdale/Phoenix, Ariz.

   The purpose of this study is to compare disease-free survival (DFS) of patients with high-risk cutaneous squamous cell carcinoma (CSCC) treated with adjuvant cemiplimab, versus those treated with placebo, after surgery and radiation therapy (RT). The secondary objectives of the study is to compare the overall survival (OS) of high-risk CSCC patients treated with adjuvant cemiplimab, versus those treated with placebo, after surgery and RT -To compare the effect of adjuvant cemiplimab with that of placebo on patients' freedom from locoregional recurrence (FFLRR) after surgery and RT; to compare the effect of adjuvant cemiplimab with that of placebo on patients' freedom from distant recurrence (FFDR) after surgery and RT; to compare the effect of adjuvant cemiplimab with that of placebo on the cumulative incidence of second primary CSCC tumors (SPTs) after surgery and RT; to evaluate the safety of adjuvant cemiplimab and that of placebo in high-risk CSCC patients after surgery and RT; to assess cemiplimab pharmacokinetics and immunogenicity in human serum.

10. A Study to Evaluate Regional Radiotherapy in Biomarker Low-Risk Node Positive Breast Cancer

    Jacksonville, Fla.

    The purpose of this study is to compare the effects on low-risk breast cancer receiving usual care that includes regional radiation therapy, with receiving no regional radiation therapy. Researchers want to see if not giving this type of radiation treatment works as well at preventing breast cancer from coming back.
