The Potential for Metformin to Improve Tumor Oxygenation in Locally Advanced Cervix Cancer: A Phase II Randomized Trial

31 May 2022

Cervical cancer remains an important health problem worldwide. Poor tumor oxygenation (hypoxia) is associated with inferior survival in cervical cancer and resistance to radiation treatment. Hypoxia-modifying therapies improve survival, but existing therapies are impractical and/or toxic. Metformin, a non-toxic drug for diabetes, has been shown to decrease tumor hypoxia in animal studies and its use is associated with better survival in diabetic cancer patients. It is hypothesized that metformin may decrease cervical tumor hypoxia and thereby improve tumor response to radiation and survival in patients with locally advanced cervix cancer. This is a randomized, multicenter phase II study of standard chemoradiation in combination with metformin versus standard chemoradiation alone in women with locally advanced cervix cancer. Women randomized to the metformin group will take metformin starting 1 week prior to standard chemoradiation and throughout the duration of external radiation treatment. Tumor hypoxia will be measured by a special X-ray test called positron emission test (PET) performed with a hypoxia dye called FAZA. The main purpose of this study is to see if metformin decreases tumor hypoxia measured on FAZA-PET; information about response and side effects will also be collected.

19F Hot Spot MRI of Human Adipose-derived Stem Cells for Breast Reconstruction

31 December 2021

Six female patients (>18 years of age, pre-menopausal) who have had loco-regional (lumpectomy and radiation) therapy for breast carcinoma and have been at least one-year disease free will undergo liposuction, the autologous SVF cell fraction will be isolated and labeled with CS-1000 in the operating room without entering cell culture, which will then be returned to the patient at the site of breast grafting. Patients will receive a pre-screening MRI . Patients will have an MRI scans over a period of 1 month at Johns Hopkins. Follow-up MRIs at 6,12, and 18 months will also be performed. Only at Johns Hopkins with fluorine being done as part of this investigational study. By performing fluorine MRI and quantification of 19F signal, we hypothesize that the engraftment of transplanted cells can be tracked in ways not possible before, using the total fluorine signal as surrogate marker for cell persistence and survival. We expect that a clinically successful outcome (maintenance of breast contour and volume) will be positively correlated with cell survival. The outcome of this study may pave the way for using 19F MRI cell tracking as a new tool for stem cell therapy in a variety of clinical applications.

The VIDYA Study-designed to Determine if Patients With a History of Basal Cell Carcinoma Are More Inclined to Return for Follow-up if Their Risk of a Subsequent Basal Cell Carcinoma is Quantitated.

30 June 2021

While current guidelines call for annual follow-up for patients with a history of basal cell carcinoma, compliance with these guidelines is imperfect. It is hypothesized that if patients are informed of the quantitative risk of a subsequent basal cell carcinoma based on individualized risk factors, the compliance rate for follow-up will improve. The primary objective of this study is to assess one-year compliance with requested follow-up for patients with recent history of basal cell carcinoma, among those who receive standard sun avoidance counseling and request for follow-up compared to those who receive, in addition, an estimate of their mathematical risk of a subsequent basal cell carcinoma based on individualized risk factors.

Tumor-Agnostic Precision Immuno-Oncology and Somatic Targeting Rational for You (TAPISTRY) Platform Study

18 January 2021

TAPISTRY is a Phase II, global, multicenter, open-label, multi-cohort study designed to evaluate the safety and efficacy of targeted therapies or immunotherapy as single agents or in rational, specified combinations in participants with unresectable, locally advanced or metastatic solid tumors determined to harbor specific oncogenic genomic alterations or who are tumor mutational burden (TMB)-high as identified by a validated next-generation sequencing (NGS) assay. Participants with solid tumors will be treated with a drug or drug regimen tailored to their NGS assay results at screening. Participants will be assigned to the appropriate cohort based on their genetic alteration(s). Treatment will be assigned on the basis of relevant oncogenotype, will have cohort-specific inclusion/exclusion criteria, and, unless otherwise specified, will continue until disease progression, loss of clinical benefit, unacceptable toxicity, participant or physician decision to discontinue, or death, whichever occurs first.

Trial number:
