Ethan Neumann was a patient-scientist at Johns Hopkins who dedicated his life to researching fibrolamellar liver cancer, the disease that claimed his life at 27.

A research fellowship is being established in his name to support future scientists. Help honor his legacy.

Ethan Neumann, a 27-year-old PhD candidate in my lab, devoted himself to studying #fibrolamellar carcinoma, the cancer that claimed his life last week.

Please support his father’s effort to establish an endowed research fellowship in Ethan’s name ⬇️

We lost someone extraordinary: Ethan Neumann, a PhD candidate in my lab, worked tirelessly to study fibrolamellar carcinoma - the cancer that would ultimately claim his life
Just before his died, he officially earned his doctorate and became Dr. Neumann

The breakthrough builds on work Paul Thomas conducted through a ASPIRE Award granted in partnership with the Fibrolamellar Cancer Foundation. It offers new hope for FLC patients — and a new path forward for therapeutic vaccines targeting so-called “undruggable” cancer drivers.

From bench to bedside! In a Phase 1 trial, a vaccine targeting a neoantigen in fibrolamellar hepatocellular carcinoma (FLC), a rare liver cancer primarily affecting younger people, showed significant clinical benefit when combined with immune checkpoint inhibitors. www.nature.com/articles/s41...

A therapeutic peptide vaccine for fibrolamellar hepatocellular carcinoma: a phase 1 trial - Nature Medicine
In this phase 1 trial, treatment of patients with fibrolamellar hepatocellular carcinoma with a therapeutic peptide vaccine targeting the fusion kinase DNAJB1–PRKACA, which is the driver of the disease, together with nivolumab and ipilimumab, was safe and led to encouraging preliminary clinical responses, and translational analysis showed activation of immune responses.

An experimental vaccine targeting fibrolamellar carcinoma, a rare liver cancer in young people, demonstrated disease control in 75% of early trial participants and was generally well-tolerated. doi.org/hbcffc
Experimental liver cancer vaccine shows promise for young patients in early trial
An experimental cancer vaccine developed at the Johns Hopkins Kimmel Cancer Center and its Bloomberg~Kimmel Institute for Cancer Immunotherapy has shown early promise in a Phase I clinical trial for a rare form of liver cancer that primarily affects children and young adults.

6) Immunohistochemistry: PCT is positive in 77% of FLC, but absent in other primary or secondary liver tumors.

In conclusion
👉 serum and tumor PCT = sensitive & specific biomarker for fibrolamellar hepatocellular carcinoma.

2) Fibrolamellar carcinoma (FLC) affects young patients and lacks reliable biomarkers (AFP/CA19-9 usually normal). An unexpectedly high PCT level in one case led us to investigate PCT across two cohorts (Europe and USA)

1) We recently identified as serum tumor biomarker of fibrolamellar carcinoma, procalcitonin, with @zucmanrossi.bsky.social and @markyarchoan.bsky.social that you can find in www.medrxiv.org/content/10.1...

We show that the liver cancer fibrolamellar carcinoma is characterized by increased mitochondrial calcium levels, which leads to inhibition of BCAA catabolism. Congratulations to all the authors, and many thanks to collaborators @lucasbsullivan.bsky.social @shaoenong.bsky.social
