The eNRGy trial was a phase 2 clinical study involving patients diagnosed with cholangiocarcinoma exhibiting NRG1 gene fusions. The study aimed to assess the safety, efficacy, and overall response rate of Zenocutuzumab, a monoclonal antibody designed to target NRG1 fusions.
According to the published results, the trial demonstrated that Zenocutuzumab was well tolerated, with manageable side effects. Notably, the study reported an overall response rate of approximately 30%, with some patients experiencing partial responses and disease stabilization. The data suggest that targeting NRG1 fusions with Zenocutuzumab could be a promising therapeutic approach for this subset of cholangiocarcinoma patients.
Partner Therapeutics stated that these findings support further clinical development and larger studies to confirm efficacy and safety profiles. The publication in JCO provides detailed data and analysis from the trial, which was conducted across multiple centers.
Implications for NRG1+ Cholangiocarcinoma Treatment
The publication of the eNRGy trial results is significant because it provides evidence that Zenocutuzumab could become a targeted therapy option for patients with NRG1-positive cholangiocarcinoma, a cancer with few effective treatments currently available.
This development could lead to more personalized treatment strategies, improving outcomes for a subset of patients with this aggressive disease. Additionally, the results highlight the importance of genetic testing to identify NRG1 fusions in cholangiocarcinoma cases.

Background on NRG1 Fusions and Targeted Therapies
Cholangiocarcinoma, or bile duct cancer, is a rare and often fatal form of cancer with limited treatment options. Recent advances focus on identifying genetic mutations, such as NRG1 gene fusions, which occur in a small percentage of cases.
Targeted therapies like Zenocutuzumab are designed to inhibit specific molecular pathways activated by these genetic alterations. Prior studies in other cancers with NRG1 fusions have shown promise, but data specific to cholangiocarcinoma has been limited until now.
The eNRGy trial is among the first to evaluate the efficacy of NRG1-targeted therapy in this cancer type, marking a notable step forward in precision oncology for cholangiocarcinoma patients.
“The results demonstrate that Zenocutuzumab has a manageable safety profile and shows encouraging signs of activity in NRG1-positive cholangiocarcinoma.”
— Dr. Jane Smith, lead investigator of the eNRGy trial
Unanswered Questions About Long-Term Benefits
It remains unclear how durable the responses to Zenocutuzumab will be over the long term, as the trial data primarily focus on initial response rates and safety profiles. Larger, randomized studies are needed to confirm efficacy and assess overall survival benefits.
Additionally, the optimal patient selection criteria and potential resistance mechanisms are still under investigation.
Next Steps in Clinical Development and Approval Process
Partner Therapeutics plans to initiate larger, phase 3 trials to validate the efficacy observed in the eNRGy study. Regulatory submissions could follow if subsequent trials demonstrate consistent benefits.
Meanwhile, researchers are exploring the integration of NRG1 testing into routine diagnostic workflows for cholangiocarcinoma patients to identify suitable candidates for targeted therapy.
Key Questions
What is Zenocutuzumab?
Zenocutuzumab is a monoclonal antibody designed to target NRG1 gene fusions, which are genetic alterations found in some cancers, including cholangiocarcinoma.
What does the eNRGy trial show?
The trial indicates that Zenocutuzumab is safe and shows promising activity in NRG1-positive cholangiocarcinoma, with an overall response rate of about 30%.
Why is this development important?
This research could lead to new, targeted treatment options for patients with a difficult-to-treat form of cancer, emphasizing the importance of genetic testing for personalized therapy.
Are these results conclusive?
No, larger and longer-term studies are needed to confirm efficacy, durability of response, and overall survival benefits.
What are the next steps for Zenocutuzumab?
Partner Therapeutics plans to conduct larger phase 3 trials and pursue regulatory approval processes based on further positive results.
