IMMUNOTHERAPY

This year’s Hot Topic Symposium during Society for Immunotherapy of Cancer’s 34th Annual Meeting, co-chaired by Jennifer A. Ligibel, MD, and Jennifer Mcquade, MD, MS, MA, focused on modifiable factors that can affect tumor response to treatment.

Although immune checkpoint inhibitor therapy has represented a paradigm shift in the treatment of multiple types of cancer, many patients’ cancers do not respond at all to these therapies or develop resistance after an initial period of response, according to Julie R. Brahmer, MD. 

The advent of immunotherapy has delivered unprecedented and durable anti-tumor responses as well as long-lasting survival benefits in some patients. Yet many clinicians may not be familiar with managing the unique toxicities that accompany these emerging cancer treatments.

The combination of bemcentinib, a first in class selective AXL inhibitor, and pembrolizumab is well-tolerated in patients with composite AXL-positive non–small cell lung cancer, according to updated data presented at Society for Immunotherapy of Cancer’s 34th Annual Meeting.

The use of CMP-001, an intratumoral toll-like receptor 9 agonist, is capable of triggering durable responses when used in combination with pembrolizumab for patients with PD-1 resistant metastatic melanoma according to results from a phase Ib study presented at the Society for Immunotherapy of Cancer’s 34th Annual Meeting.

The anti–CD27 agonist, MK-5890, demonstrated acceptable safety findings when administered as monotherapy and in combination with pembrolizumab in numerous solid tumors, according to findings of an open-label phase I trial presented by Ronnie Shapira-Frommer, MD, head of the Onco-Gynecological Cancer Unit at The Ella Lemelbaum Institute for Immuno-Oncology, Ramat Gan, Israel, during the Society for Immunotherapy of Cancer’s 34^th Annual Meeting.

Immunotherapy combination regimens have revolutionized the first-line treatment paradigm for patients with clear cell renal cell carcinoma, explained Robert J. Motzer, MD, at the <em>37th Annual</em> CFS.

There are at least two dozen different B-cell maturation antigen-directed therapies being explored in clinical trials, Sham Mailankody, MBBS, told attendees at the 37 Annual CFS.&nbsp;Mailankody, an assistant attending physician at Memorial Sloan Kettering Cancer Center in New York, New York, highlighted the most promising anti-BCMA agents across several modalities, including CAR T-cell therapy, bispecific antibodies, and antibody-drug conjugates.

David Maloney, MD, PhD, medical director, Cellular Immunotherapy Integrated Research Center, Fred Hutchinson Cancer Research Center, discusses the results of the ZUMA trial and how chimeric antigen receptor CAR T-cell therapy is changing the treatment landscape for non-Hodgkin lymphoma.

Non-Hodgkin Lymphoma

In solid tumors, targeted therapies are scarce for patients with mutations like KRAS or fusions like NRG1. Two clinical trials are investigating novel agents targeting these alterations to improve outcomes in patients with these particular genetic drivers of disease. The research was recently presented at the 2019 AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics.

The results of multiple studies suggest that bacteria may influence both cancer growth and the immune system, with certain species linked to improved immune surveillance of cancer. Some bacteria interact with the host&rsquo;s immune system through paracrine factors to shape the immune system&rsquo;s response to cancer.

Emerging from the recent 2019 World Conference on Lung Cancer&nbsp;are several notable developments, Robert L. Ferris, MD, PhD, wrote in this issue of&nbsp;<em>Targeted Therapies in Oncology.&nbsp;</em>

<br /> In the future, we&rsquo;re going to do combination therapies. They will be used in a subset of patients better defined by profiling,&rdquo; Kenneth C. Anderson, MD, told an audience at the Charlotte Plasma Cell Disorder Congress in North Carolina.

Marcelo C. Pasquini, MD, discusses the rationale for analyzing real-world data for the use of tisagenlecleucel, a chimeric antigen receptor T-cell therapy, as a treatment for patients with acute lymphoblastic leukemia and diffuse large B-cell lymphoma. This CD19 CAR T cell was approved 2 years ago for use in both ALL and DLBCL.

Patients with early triple-negative breast cancer receiving neoadjuvant treatment with the combination of pembrolizumab and chemotherapy showed extended pathological complete response rates by 13.6 percentage points compared with chemotherapy alone in the phase III KEYNOTE-522 study.

Certain patients with cancer who are treated using immune checkpoint inhibitors may develop a form of insulin-dependent diabetes that is associated with immune-related adverse events resulting from therapy, according to research published in <em>The Lancet Diabetes &amp; Endocrinology</em>.

Now in it 24th year, the annual International Congress on Hematologic Malignancies: Focus on Leukemias, Lymphomas, and Myeloma, hosted by Physicians&rsquo; Education Resource, LLC, continues to bring significant advances in hematology to the forefront.

To improve the efficacy of chimeric antigen receptor T-cell therapies, Nirali N. Shah, MD, MHSc, suggested including new constructs that target more than 1 antigen in patients with acute lymphoblastic leukemia, during a presentation at the 2019 SOHO Annual Meeting.<br /> &nbsp;
