SKIN CANCERS

Using a measure known as the growth modulation index, patients with TRK fusion–positive cancers who were treated with larotrectinib had a clinically meaningful improvement in progression-free survival compared with the time to progression on their prior treatment, an analysis of patients enrolled in 1 of 3 clinical trials has found.

Three clinical trials presented at the 2019 ESMO Congress show that the tropomyosin receptor kinase inhibitor larotrectinib continues to show anti-tumor activity, including long-lasting objective responses and low toxicity, according to results from an integrated analysis.

“New therapies have increased the median survival for advanced-stage melanoma from approximately 9 months before 2011 to at least 2 years, based on [data from] clinical trials,” Elizabeth Ward, PhD, and colleagues wrote about their report on cancer burden in younger patients.

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

Michael R. Migden, MD, spoke with a group of physicians during a <em>Targeted Oncology </em>live case-based peer perspectives discussion about responses in patients with cutaneous squamous cell carcinoma to immunotherapy treatment.

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;

In a recent review of the 5-year outcomes from the COMBI-d and COMBI-v trials published in the&nbsp;New England Journal of Medicine, investigators saw long-term benefit with the use of dabrafenib plus trametinib as first-line treatment in about one-third of patients with unresectable or metastatic melanoma and&nbsp;BRAF V600E or V600K mutations.

Keith T. Flaherty, MD, discusses the combination regimens and the potential role for a 3-drug regimen as treatment for patients with melanoma. He says investigators have been searching for new combination strategies beyond the combination of BRAF and MEK inhibitors.

In an interview with&nbsp;Targeted Oncology, Shailender Bhatia, MD, highlighted the key takeaways from the 5 abstracts he found most significant at the 2019 ASCO meeting for the treatment of patients with melanoma.

In an interview with&nbsp;Targeted Oncology, Sattva S. Neelapu, MD, discussed the evolving role for CAR T-cell therapy in patients with B-cell lymphomas. He also highlighted the toxicities commonly associated with these therapies and how physicians can treat these AEs as they arise.

In an interview with <em>Targeted Oncology</em>, Michael Atkins, MD, discussed the latest follow-up data from the combination of nivolumab and ipilimumab across 2 trials and next steps in the research with this combination for patients with advanced melanoma.

In the largest genomic study of Merkel cell carcinoma tumors to date, investigators identified 2 distinct molecular subgroups, an ultraviolet light&ndash;driven subtype and a viral-driven subtype, which matched with tumor mutational burden classifications.&nbsp;

The initial pilot study of CTL019 in heavily pretreated CD19-positive hematologic malignancies demonstrated the feasibility of CAR T-cell therapy in patients with CLL. A presentation at the 2019 American Society of Gene &amp; Cell Therapy Annual Meeting reported 2 cases of chemotherapy-resistant CLL, with ongoing follow- up at 8 years showing persistence of CAR-engineered T cells and sustained remission, as determined by flow cytometry and deep sequencing of immunoglobulin H rearrangements.&nbsp;

In an interview with <em>Targeted Oncology</em>, Chong, a fellow at the University of Pennsylvania, discussed the 4-year follow-up data for CAR T cells in patients with DLBCL and FL. She also addressed the challenges that need to be overcome in order to give more patients access to this type of therapy.

A phase III clinical trial has begun to investigate the use of cemiplimab as an adjuvant treatment after surgery and radiation therapy in patients with high-risk cutaneous squamous cell carcinoma.<br /> &nbsp;

In the phase I/II TRANSCEND CLL 004 study, chimeric antigen receptor T-cell therapy lisocabtagene maraleucel led to undetectable minimal residual disease in patients with relapsed/refractory chronic lymphocytic leukemia.

The combination of bempegaldesleukin and nivolumab was granted a breakthrough therapy designation by the FDA&nbsp;for the treatment of patients with previously untreated unresectable or metastatic melanoma.

Kieron Dunleavy, MD, discussed current approaches to treating patients with MCL, highlighting peer discussions on the subject and information about the ZUMA-2 trial, in an interview with&nbsp;<em>Targeted Oncology</em>.

Nivolumab demonstrated long-term survival benefit in heavily pretreated patients with advanced melanoma, renal cell carcinoma, and non&ndash;small cell lung cancer, according to an analysis of 5-year results from the CA209-003 trial. The analysis also identified favorable and adverse factors associated with survival that could inform future use of nivolumab.&nbsp;

David Polsky, MD, PhD, discusses the findings from a liquid biopsy analysis of the COMBI-d trial, which is a phase III trial investigating the combination of dabrafenib and trametinib or dabrafenib alone in patients with BRAF V600E/K&ndash;mutant melanoma. Investigators found an association between the presence of baseline circulating tumor DNA (ctDNA) and a poor prognosis with the treatment of BRAF inhibitors.

In an interview with&nbsp;Targeted Oncology, Rodabe N. Amaria, MD, discussed the guidelines and recommendations outlined by the INMC. She also highlighted the importance of genomic testing in the neoadjuvant setting of melanoma.&nbsp;

The FDA has granted an orphan drug designation to MB-102, a CD123-directed CAR T-cell therapy, for the treatment of patients with acute myeloid leukemia.

Anna C. Pavlick, DO, MS, MBA, spoke with a group of physicians about the systemic therapy options, including immunotherapeutics, for treating patients with cutaneous carcinomas in a recent&nbsp;<em>Targeted Oncology&nbsp;</em>live case-based peer perspectives discussion. Pavlick explained treatment options based on 2 case scenarios of patients with cutaneous malignancies.

In an interview with&nbsp;<em>Targeted Oncology</em>, David Polsky, MD, PhD, discussed the findings from this analysis in patients with&nbsp;<em>BRAF</em>-mutant, unresectable, metastatic melanoma. He highlighted the next steps necessary for validating these findings and potentially using ctDNA to help inform treatment decisions for patients with metastatic melanoma.
