Learn about clinical trials and discover how you can help shape the future of healthcare. The use of both Salmonella and IL‐2 in cancer has been limited by systemic toxicity (Sorenson et al. 2010 ; Modiano et al. 2012 ). Here, we report the results of a prospective, open label, phase I dose‐cohort escalation clinical study evaluating safety of orally administered, genetically engineered S. Typhimurium in combination with amputation and adjuvant doxorubicin in dogs with non‐metastatic appendicular osteosarcoma. Since the 1997 FDA approval of rituximab, a mAb designed to target the B-cell marker CD20, a large panel of mAbs has been approved for the treatment of both hematologic and solid malignancies 6 mAbs have quickly become a mainstay of cancer treatment by consistently increasing patient remissions with minimal toxicity 6 Initially, mAb therapy was impeded by their production in mice and subsequent immunogenicity in humans 7 Today, a number of techniques are used to humanize” murine antibodies for clinical use by grafting the mouse complementarity-determining region onto a recombinant human immunoglobulin backbone 7 The development of technology to speciate antibodies has led to a variety of clinical trials in companion dogs 8 New forms of mAbs, such as bispecific antibodies and immunoconjugates, are also being developed and show promise in initial clinical trials. Patients with diffuse large B-cell lymphoma (DLBCL) or pediatric acute lymphoblastic leukemia (ALL) do not typically have many treatment options if they relapse more than once or if their cancer fails to respond to multiple rounds of chemotherapy, radiation therapy or stem cell transplants. Dogs with certain naturally occurring cancers may be better than other animal models of human cancers because mice and rats used in many cancer drug-testing models must be implanted with human cancer cells to mimic specific types of tumors, Fan said. To better help patients whose cancer is not responsive to standard treatment, University of Minnesota Health physicians became part of two phase II multi-center clinical trials Cancer Treatment St Paul MN testing a chimeric antigen receptor (CAR) T-cell immunotherapy called Kymriah that, thus far, has shown remarkable results using patients’ immune systems to battle cancer. In addition, the center currently runs more than 180 cancer-related clinical trials for a wide array of therapies, diagnostics and preventive options, and it offers opportunities to participate in community-based trials for cancer survivorship research. These types of treatments are typically limited to academic centers with bone marrow transplant expertise and the necessary regulatory accreditations to deliver cell therapies and particularly to centers that have been involved in CAR T-cell clinical trials,” Dr. Bachanova says. Fort Sanders Regional Medical Center (Knoxville, Tenn.).The Thompson Cancer Survival Center at Fort Sanders Regional Medical Center delivers cancer care at its primary location in downtown Knoxville, and at its facilities in West Knoxville, Oak Ridge and Sevierville, Tenn. In contrast, responses to immunotherapy may take up to several months due to the time needed to induce an adaptive immune response 3 , 105 During that period of time, an increase in tumor size may occur due to the infiltration of immune cells into the mass 3 , 105 The unique biological response to immunotherapy has led to the development of immune-related response criteria to evaluate human clinical trials 105 , and the implementation of similar criteria may be necessary for the evaluation of veterinary trials. Generally, these are treatments not taught to doctors in medical schools, not advertised in medical journals and also generally not covered by health insurance policies,” he says, adding that they are documented to have a higher efficacy than conventional cancer treatments. Advocate Lutheran General Hospital (Park Ridge, Ill.). The three-story Advocate Cancer Institute at Advocate Lutheran General Hospital is part of 27-hospital Advocate Aurora Health, a merged entity between Downers Grove, Ill.-based Advocate Health Care and Milwaukee-based Aurora Health Care.
