IMMUNOTHERAPY

Jamie E. Chaft, MD, discusses biomarkers used to identify patients with lung cancer who would benefit from immunotherapy and the possibility for future biomarkers in this setting.

“We don’t have a good understanding of why some patients have a robust response to immunotherapy and others do not. That’s important, not only in terms of selecting patients but also in terms of the therapy approach. This is one reason why clinical trials are incredibly important.”

Joshua Brody, MD, discusses how he sees the use of immunotherapy evolving in coming years.

Prasad S. Adusumilli, MD, FACS, discusses where he sees chimeric antigen receptor T-cell therapy fitting into the treatment landscape for patients with solid tumors.

Treatment with sacituzumab govitecan resulted in “compelling evidence of efficacy” in patients with metastatic triple-negative breast cancer, leading to an early halt of the phase III ASCENT study, announced Immunomedics in a press release.

Durable remissions were elicited with KTE-X19 in a majority of patients with relapsed or refractory mantle cell lymphoma, according to the updated results from the ZUMA-2 trial published in the New England Journal of Medicine. The treatment did, however, cause serious adverse events that were consistent with known toxicities of chimeric antigen receptor T-cell therapy.

In an interview with Targeted Oncology, Prasad S. Adusumilli, MD, FACS, discussed the expansion of chimeric antigen receptor T-cell research in the solid tumor space and the challenges researchers will need to overcome in order to make this therapy effective for patients outside of the hematologic treatment landscape.

Jonathan C. Trent, MD, PhD, discusses some of the recent immunotherapeutic advances in the treatment landscape for patients with sarcoma, particularly with immune checkpoint inhibitors.

GEN-1 immunotherapy demonstrated dose-dependent efficacy results in newly diagnosed patients with advanced epithelial ovarian, fallopian tube, or primary peritoneal cancer when treated in combination with the standard of care, according to results from the OVATION 2 study. Based on positive data in the phase I portion, the study is moving on to phase II with enrollment expected to begin in the second half of the year.

Microsatellite instability has been an FDA-indicated biomarker for immunotherapy since 2017, when the PD-1 inhibitor pembrolizumab was approved for patients with solid tumors found to be mismatch repair deficient or MSI high. Other approvals since then, such as for the combination of ipilimumab and nivolumab in patients with MSI-H/dMMR metastatic colorectal can­cer, have established the relevance of cancer thera­pies for tumors with this biomarker specifically rather than tumor histology alone.

David Miklos, MD, PhD, describes the toxicity profile of KTE-X19, a chimeric antigen receptor T-cell therapy, in the ZUMA-2 trial.

In an interview with Targeted Oncology at the 2020 International Congress on Hematologic Malignancies, Noopur Raje, MD, discussed emerging CAR T-cell therapies in multiple myeloma. She also explained how CAR NK cells differ from other CAR agents.

Dylan Essner explains how Epic, an electronic medical record, can be used by nurses and oncology providers who are treating patients with chimeric antigen receptor T-cell therapy.

Use of an off-the-shelf chimeric antigen receptor T-cell product may be feasible for use in patients with relapsed/refractory B-cell malignancies for whom no other available therapies exist, according to results of a phase I trial in adult and pediatric patients that were presented at the 2020 Transplant & Cellular Therapies Meeting in Orlando, Florida.

Treatment with immune checkpoint inhibitors appears to elicit limited clinical activity in patients with osteosarcoma. In a study, investigators at MD Anderson Cancer Center found that certain factors like poor infiltration of the tumor by immune cells, low activity from available T cells, a lack of immune-stimulating neoantigens, and multiple immune-suppressing pathways may interfere with response to immunotherapy in these patients, according to a press release from the organization.<br /> &nbsp;

Craig L. Slingluff, MD, explains the rationale behind part B1 of the MAVIS study , which is investigating the use of the Seviprotimut-L&nbsp;vaccine in melanoma.

Outpatient treatment with&nbsp;lisocabtagene maraleucel&nbsp;had consistent efficacy and safety with that of a previously reported clinical trial involving patients who were treated at university medical centers, according to results of 3 studies reported at the 2020 Transplantation &amp; Cellular Therapy Meetings in Orlando, Florida.

In an interview with&nbsp;Targeted Oncology at the&nbsp;2020 Transplantation &amp; Cellular Therapy Meetings, Craig Sauter, MD, discussed the retrospective real-world review of patients with hematologic malignancies who developed cytopenia post-chimeric antigen receptor T-cell therapy.

Plinabulin in combination with docetaxel, doxorubicin, cyclophosphamide, and pegfilgrastim led to a dose-dependent increase in mean haptoglobin and absolute neutrophil count, demonstrating potency in the stimulation of the adaptive and innate immune system following previous positive efficacy and safety results, according to data analyzed from the phase III BPI-2358-106 study presented at the 2020 American Society of Clinical Oncology-Society for Immunotherapy of Cancer Clinical Immuno-Oncology Symposium.

Matthew Krebs, MBChB, PhD, explains the rationale for a phase II study of bemcentinib, a first-in-class selective AXL inhibitor, in combination with pembrolizumab in patients with advanced non&ndash;small cell lung cancer, which he presented at the 2019 Society for Immunotherapy of Cancer Annual Meeting.

Jason Luke, MD, FACP, discusses promising clinical research around intratumoral immunotherapy.

The majority of patients with relapsed or refractory non-Hodgkin lymphoma and chronic lymphocytic leukemia who were participants in a phase I/IIa trial had clinical responses to treatment with TAK-007, a cord blood&ndash;derived chimeric antigen receptor natural killer&ndash;cell therapy that targets CD19, with no major toxicities experienced by patients, according to a press release from the University of Texas MD Anderson Cancer Center.

Jason Williams, MD, the director of Interventional Oncology and Immunotherapy oncologist at the Williams Cancer Institute, discusses a study in which an immunotherapy combination was administered intratumorally to patients with liver metastases linked to breast cancer, which he presented in a poster at the 2019 Society of Immunotherapy of Cancer Annual Meeting.

The combination of talimogene laherparepvec plus pembrolizumab led to a promising objective response rate in patients with advanced sarcoma who typically have limited treatment options, according to a phase II clinical trial&nbsp;&nbsp;published in&nbsp;<em>JAMA Oncology</em>.

In an interview with&nbsp;Targeted Oncology, Shoba A. Navai, MD,&nbsp;discussed the evolving role of CAR T-cell therapy in solid tumors, including sarcomas and how the efficacy and safety compare with CAR T cells in this space compared with hematologic malignancies.
