Community Practice Connections™: 14th Annual International Symposium on Melanoma and Other Cutaneous Malignancies®


Release Date: April 30, 2018
Expiration Date: April 30, 2019
Media: Internet - based

 

Activity Overview

Community Practice Connections™ 14th Annual International Symposium on Melanoma and Other Cutaneous Malignancies® highlights current and developing therapies for patients with melanoma and Merkel cell carcinoma, including targeted therapy and immune checkpoint inhibitors. The management of skin cancer and other cutaneous malignancies has radically changed in recent years, in both the advanced and adjuvant disease settings. These changes have been paradigm-changing and great news for your patients, but they have also created educational gaps particularly for community practitioners who face the continuous challenge of staying abreast of vital issues relevant to their clinical practices. Through clinical vignettes and short interviews addressing key questions, you will hear directly from top experts in melanoma and other cutaneous malignancies on the appropriate use and sequencing of recently approved agents, companion diagnostic tests, findings from key clinical trials, updates made to treatment guidelines and recommendations, and clinical trial availability.

PER Pulse Recap™

PER Pulse Recap (1 of 3)

This first of 3 PER Pulse™ Recaps will focus on recent practice-changing results in the adjuvant setting for patients with melanoma. Below are some highlights from the meeting:
 
Dr Weber compared the results from the CheckMate 238 trial with the COMBI A/D trial, both presented at the 2017 European Society for Medical Oncology Congress and later published in the New England Journal of Medicine.

“It looks as if early on there may be a little more benefit to the BRAF/MEK adjuvant therapy with dabrafenib/trametinib, in the BRAF-mutated stage III population, but then over time, there appears to be a plateau on the immunotherapy group and less of a plateau with the targeted therapy group.”
 —Jeffrey S. Weber, MD, PhD

In the CheckMate 238 trial of 906 patients undergoing complete resection for stage IIIB, IIIC, or IV melanoma, treatment with nivolumab was compared with an active control arm of ipilimumab.1
 
The primary endpoint of relapse-free survival (RFS) was met:
  • Twelve-month rate of RFS was significantly increased in the nivolumab group compared with the ipilimumab group (HR for disease recurrence or death, 0.65; 97.56% CI, 0.51-0.83; P<.001).
  • Grade 3 or 4 treatment-related adverse effects were lower in the nivolumab group (14.4%) than in the ipilimumab group (45.9%).
The COMBI A/D trial of 870 patients with resected stage III melanoma with BRAF V600E or BRAF V600K mutations compared treatment with dabrafenib plus trametinib to placebo.2
There was a significant increase in RFS with the combination treatment, as shown in the slide below.


While it is difficult to compare results from different trials, both BRAF plus MEK inhibition or PD-1 blockade with nivolumab appear to be fairly equivalent as frontline adjuvant therapy options following resection of stage III melanoma:
  • Two- and 3-year RFS and overall survival curves with BRAF plus MEK seem to separate and maintain the separation over time.
  • RFS curves for nivolumab are still maturing but may be suggestive of a plateau that may not be achieved with BRAF plus MEK inhibition.
  • Nivolumab adjuvant therapy may not be as efficacious in patients with BRAF-mutated disease as it is in those with BRAF wild-type disease.
  • In patients with stage III, BRAF-mutated disease, toxicity of BRAF plus MEK may be higher, with more patients discontinuing treatment because of adverse effects (26% vs 4%).

PER Pulse Recap (2 of 3)

This second of 3 PER Pulse™ Recaps will focus on an emerging and exciting area of cancer research, the effect of the microbiome on immunotherapy treatment.

“There is a relationship between the gut, the tumor microenvironment, and the bacteria within our intestine that can shape our immune response and even shape how patients respond to therapy.”   —Jennifer A. Wargo, MD

Below are some highlights from the meeting featuring Dr Wargo:
 
Although immune checkpoint blockade represents a major advance in the treatment of melanoma and other cancers, durable responses are not consistently yielded among patients. Research into discovering predictive biomarkers is under way and could enhance clinicians’ capability to personalize care across treatment settings for patients with melanoma and other cutaneous malignancies.
 
Treatment response is affected by multiple factors, including:
  • Systemic immunity
  • Tumor microenvironment
  • Tumor genome and epigenome
  • Environmental factors, including the microbiome
 
Microbial imbalance of the gut microbiome (dysbiosis) is associated with many diseases, and there is compelling evidence emerging that the microbiome may also influence response to cancer therapy, especially treatment with immunotherapy. In a recent study by Gopalakrishnan et al,1 samples of the oral and gut (fecal) microbiome were analyzed in 112 patients with metastatic melanoma starting treatment with anti‒PD-1 therapy. 
 
The following findings were reported:
  • Responders (n = 30) to anti‒PD-1 therapy had a higher diversity in their gut microbiome than did nonresponders (n = 13; P<.01).
  • Higher diversity of the gut microbiome was associated with improved progression-free survival in patients with melanoma on anti‒PD-1 therapy (P<.05).


 
Further investigation through immune profiling of responding patients with a favorable gut microbiome, as well as in germ-free mice that received fecal transplants from responding patients, showed evidence of heightened systemic and antitumor immunity. Further study is ongoing to elucidate the mechanisms and to test strategies to improve therapeutic responses in patients.

PER Pulse Recap (3 of 3)

This third of 3 PER Pulse™ Recaps will focus on unmet needs in melanoma, including patients with central nervous system (CNS), mucosal, and ocular diseases.
 
A significant unmet clinical need remains for patients with noncutaneous melanoma, highlighted by the drastic differences in the survival curves between cutaneous and noncutaneous melanoma. As data begin to report out at scientific meetings, some potentially practice-changing results are beginning to emerge. Below are some highlights from the meeting featuring Dr Luke:
 
Dr Luke noted the exciting future potential of immunotherapy to address some of the unmet needs in patients with melanoma who have brain metastases.

“I would even postulate that in patients who have low-volume brain metastases, the use of immunotherapy should be prioritized over radiation.”
 — Jason J. Luke, MD, FACP

Historically, patients with melanoma with brain metastases had survival rates of approximately 6 months. Impressive data presented at the 2017 American Society of Clinical Oncology Annual Meeting from the CheckMate 204 study1 showed that the group of patients treated with nivolumab plus ipilimumab combination therapy yielded intracranial objective response rates of 56% (95% CI, 44-68), with 19% of patients experiencing a complete response. A fair degree of concordance between the intracranial and extracranial response was demonstrated.


  • Differing primary molecular and immune biology are found in cutaneous versus noncutaneous melanomas:
  • Acral and mucosal melanomas are associated with changes in the structure of the DNA and mutation sequences of unknown etiology.
  • Biology underpinning different melanoma types includes MAPK dependency; however, other molecular signaling pathways are also involved:
    • Acral or mucosal: KIT
    • Uveal: GNAQ/11, PKC
    • CNS: PI3K/AKT 
  • Checkpoint immunotherapy, although a standard of care, may be of less value in some noncutaneous melanoma cases: 
  • Benefit with immune checkpoint inhibitors in uveal melanoma is not clinically meaningful.
  • Emerging data with pembrolizumab in patients with mucosal melanoma have shown durable benefit in some patients.2
  • Participation in clinical trials should be prioritized for patients with noncutaneous melanoma.
