David Ashley

Overview:

Dr. Ashley's primary research focus is laboratory based, investigating the role of immunotherapy as a novel approach to the treatment of tumors of the central nervous system (CNS). Since beginning his appointment at the faculty level at Duke in August of 1995 his activities have centered on two main areas of investigation. The first involves both in vivo and in vitro studies of the use of molecular therapeutics to target a CNS tumor associated antigen. The second area of interest comprises a detailed analysis of the role of TGF beta, a protein messenger produced by tumors of the CNS, both in the pathogenesis of disease and as a possible target for immunotherapy.

In addition to his laboratory role Dr. Ashley is involved in the design and application of a variety of clinical research protocols in the treatment of children with malignant brain tumors.

Use of Trametinib in Children and Young Adults With Progressive Low-grade Glioma and Glioneuronal Tumors.

Low-grade gliomas/glioneuronal tumors comprise one-third of all pediatric-type CNS tumors. These tumors are generally caused by activating mutations in the mitogen-activated protein kinase (MAPK) pathway. Targeted drugs, such as trametinib, have shown promise in other cancers and are being utilized in low-grade gliomas. A retrospective chart review was conducted to evaluate radiographic response, visual outcomes, tolerability, and durability of response in progressive circumscribed low-grade gliomas treated with trametinib. Eleven patients were treated with trametinib. The best radiographic response was 2/11 partial response, 3/11 minor response, 3/11 stable disease, and 3/13 progressive disease. In the patients with partial or minor response, the best response was seen after longer durations of therapy; 4 of 5 best responses occurred after at least 9 months of therapy with a median of 21 months. Patients with optic pathway tumors showed at least stable vision throughout treatment, with 3 having improved vision on treatment. Trametinib is effective and well-tolerated in patients with progressive low-grade glioma. Best responses were seen after a longer duration of therapy in those with a positive response. Patients with optic pathway lesions showed stable to improved vision while on treatment.

The Enduring Effects of COVID for Cancer Care: Learning from Real-Life Clinical Practice.

For three years, COVID-19 has circulated among our communities and around the world, fundamentally changing social interactions, health care systems, and service delivery. For people living with (and receiving treatment for) cancer, pandemic conditions presented significant additional hurdles in an already unstable and shifting environment, including disrupted personal contact with care providers, interrupted access to clinical trials, distanced therapeutic encounters, multiple immune vulnerabilities, and new forms of financial precarity. In a 2020 perspective in this journal, we examined how COVID-19 was reshaping cancer care in the early stages of the pandemic and how these changes might endure into the future. Three years later, and in light of a series of interviews with patients and their caregivers from the United States and Australia conducted during the pandemic, we return to consider the potential legacy effects of the pandemic on cancer care. While some challenges to care provision and survivorship were unforeseen, others accentuated and amplified existing problems experienced by patients, caregivers, and health care providers. Both are likely to have enduring effects in the "post-pandemic" world, raising the importance of focusing on lessons that can be learned for the future.
