TL;DR
Partner Therapeutics has published the results of the eNRGy trial evaluating Zenocutuzumab for NRG1-positive cholangiocarcinoma. The trial’s findings are now available in the Journal of Clinical Oncology, marking a key step in the drug’s clinical evaluation.
Partner Therapeutics has officially published the results of the eNRGy trial evaluating Zenocutuzumab in patients with NRG1-positive cholangiocarcinoma. The publication, in the Journal of Clinical Oncology, confirms the completion of the trial and provides detailed data on the drug’s safety and efficacy, marking a significant milestone in its clinical development.
The eNRGy trial was a phase 2 study designed to assess the efficacy and safety of Zenocutuzumab, an investigational targeted therapy, in patients with cholangiocarcinoma exhibiting NRG1 gene fusions. Partner Therapeutics announced that the trial results, now published, demonstrate promising activity, with a notable proportion of patients experiencing tumor reduction or disease stabilization.
According to the publication, the trial enrolled a specific cohort of patients confirmed to have NRG1 gene fusions through molecular testing. The data indicate that Zenocutuzumab was generally well tolerated, with manageable side effects. The detailed results include response rates, progression-free survival, and safety profiles, although the full data set has not yet been made publicly available.
Implications of eNRGy Trial Results for NRG1+ Cholangiocarcinoma Treatment
The publication of these results is significant because NRG1 gene fusions are rare but actionable genetic alterations in cholangiocarcinoma, a cancer with limited treatment options. The positive findings suggest that Zenocutuzumab could become a targeted therapy option for this subset of patients, potentially improving outcomes.
This development also underscores the importance of molecular profiling in cholangiocarcinoma to identify patients who may benefit from targeted therapies like Zenocutuzumab. If further validated, these results could accelerate the drug’s development and regulatory review, offering hope for a new precision medicine approach in this difficult-to-treat cancer.

Background on Zenocutuzumab and NRG1+ Cholangiocarcinoma
Zenocutuzumab is an investigational bispecific antibody designed to target NRG1 gene fusions, which are genetic alterations identified in a small subset of cholangiocarcinoma cases. Prior research has suggested that NRG1 fusions can drive tumor growth, making them promising targets for therapy.
The eNRGy trial is part of Partner Therapeutics’ broader effort to develop targeted treatments for genetically defined cancers. Cholangiocarcinoma remains a challenging disease with limited effective options, especially for patients with specific molecular alterations like NRG1 fusions.
This is the first publicly available data from the eNRGy trial, which was initiated in 2022 with the goal of evaluating Zenocutuzumab’s potential in this patient population.
“The publication of the eNRGy trial results marks a critical step forward in our efforts to develop targeted therapies for NRG1+ cholangiocarcinoma. We are encouraged by the data and remain committed to advancing this promising treatment.”

Unconfirmed Efficacy and Future Regulatory Steps
While the published results are promising, full efficacy data and long-term outcomes remain unclear. It is not yet confirmed whether Zenocutuzumab will receive regulatory approval or become widely available, as additional trials and analyses are likely necessary.
Further details about response rates, durability of response, and safety profiles are expected in upcoming publications or regulatory submissions.

Next Steps for Zenocutuzumab Development and Approval Process
Partner Therapeutics is likely to conduct additional clinical trials to confirm efficacy and safety, potentially leading to regulatory submissions. The company may also seek to expand indications or molecular testing protocols to identify suitable patients more effectively.
Regulatory agencies will review the published data as part of their evaluation process, and the company may announce further trial results or seek accelerated approval pathways depending on the data’s strength.

Key Questions
What is Zenocutuzumab and how does it work?
Zenocutuzumab is an investigational bispecific antibody designed to target NRG1 gene fusions, which are genetic alterations that can drive tumor growth in certain cancers like cholangiocarcinoma.
What are NRG1 gene fusions, and why are they important?
NRG1 gene fusions are rare genetic alterations found in some cancers, including cholangiocarcinoma. They can promote cancer cell growth, making them promising targets for precision therapies like Zenocutuzumab.
When will the results from the eNRGy trial impact patient treatment options?
It is not yet clear when Zenocutuzumab might become an approved treatment, as further trials and regulatory reviews are needed. The recent publication is an important step, but additional data are required.
Are there any safety concerns with Zenocutuzumab based on the trial?
The published data indicate that Zenocutuzumab was generally well tolerated with manageable side effects, but detailed safety profiles will be clarified in future reports and regulatory assessments.
