"This submission marks an important step in advancing BIZENGRI for patients with NRG1 fusion positive cholangiocarcinoma, a population with limited treatment options, and historically poor outcomes. Cholangiocarcinoma remains a challenging and aggressive disease, and we believe these data support the potential of BIZENGRI to address a critical unmet need for patients whose tumors are driven by NRG1 gene fusions. Tissue‑based RNA testing is essential to identify rare oncogenic fusions such as NRG1 and ensure patients with these actionable alterations are not overlooked," said Pritesh J. Gandhi, Chief Development Officer, Partner Therapeutics.

The sBLA is supported by data from the eNRGy study evaluating zenocutuzumab-zbco in patients with NRG1 fusion-positive cancers, including cholangiocarcinoma. In the cholangiocarcinoma cohort, BIZENGRI demonstrated an overall response rate (ORR) of 36.8% (95% CI: 16.3, 61.6%) and a median duration of response (DOR) of 12.9 months, as assessed by blinded independent central review (BICR). Treatment was generally well tolerated, and no patients discontinued therapy due to adverse events.

Based on these data, National Comprehensive Cancer Network (NCCN) added zenocutuzumab‑zbco to the Oncology Clinical Practice Guidelines for biliary tract cancers as a Category 2A subsequent‑line therapy and as a Category 2B recommendation for front‑line treatment of NRG1 fusion–positive cholangiocarcinoma.

"Cholangiocarcinoma remains a devastating disease, particularly in the advanced setting. The identification of NRG1 gene fusions has highlighted an actionable biomarker, and the eNRGy study data suggest that targeted inhibition with zenocutuzumab may represent a meaningful treatment approach for these patients" said Dr. James Cleary, Dana-Farber Cancer Institute.

BIZENGRI received U.S. Food and Drug Administration accelerated approval for the treatment of adults with advanced unresectable or metastatic non-small cell lung cancer and pancreatic adenocarcinoma harboring NRG1 gene fusions with disease progression on or after prior systemic therapy.

About NRG1 Gene Fusions

NRG1 fusions are unique cancer drivers that create oncogenic chimeric ligands rather than the more widely described chimeric receptors (NTRK, RET, ROS1, ALK, and FGFR fusions). The chimeric ligands bind to HER3, triggering HER2/HER3 heterodimerization and activate downstream signaling pathways that cause cancer cells to grow and proliferate. Zenocutuzumab-zbco is a bispecific antibody that blocks HER2/HER3 dimerization and NRG1 fusion interactions with HER3, resulting in the suppression of these pathways. Comprehensive molecular testing, notably the combination of tissue-based DNA and RNA next generation sequencing, is essential to identify rare and actionable gene fusions like NRG1.

Important Safety Information

BOXED WARNING: EMBRYO-FETAL TOXICITY

Embryo-Fetal Toxicity: Exposure to BIZENGRI during pregnancy can cause embryo-fetal harm. Advise patients of this risk and the need for effective contraception.

WARNINGS AND PRECUATIONS

Infusion-Related Reactions/Hypersensitivity/Anaphylactic Reactions
BIZENGRI can cause serious and life-threatening infusion-related reactions (IRRs), hypersensitivity and anaphylactic reactions. Signs and symptoms of IRR may include chills, nausea, fever, and cough.

In the eNRGy study, 13% of patients experienced IRRs, all were Grade 1 or 2; 91% occurred during the first infusion.

Administer BIZENGRI in a setting with emergency resuscitation equipment and staff who are trained to monitor for IRRs and to administer emergency medications. Monitor patients closely for signs and symptoms of infusion reactions during infusion and for at least 1 hour following completion of first BIZENGRI infusion and as clinically indicated. Interrupt BIZENGRI infusion in patients with ≤ Grade 3 IRRs and administer symptomatic treatment as needed. Resume infusion at a reduced rate after resolution of symptoms. Immediately stop the infusion and permanently discontinue BIZENGRI for Grade 4 or life-threatening IRR or hypersensitivity/anaphylaxis reactions.

Interstitial Lung Disease/Pneumonitis
BIZENGRI can cause serious and life-threatening interstitial lung disease (ILD)/pneumonitis.
In the eNRGy study, ILD/pneumonitis occurred in 2 (1.1%) patients treated with BIZENGRI. Grade 2 ILD/pneumonitis (Grade 2) resulting in permanent discontinuation of BIZENGRI occurred in 1 (0.6%) patient. Monitor for new or worsening pulmonary symptoms indicative of ILD/pneumonitis (e.g., dyspnea, cough, fever). Immediately withhold BIZENGRI in patients with suspected ILD/pneumonitis and administer corticosteroids as clinically indicated.
Permanently discontinue BIZENGRI if ILD/pneumonitis ≥ Grade 2 is confirmed.

Left Ventricular Dysfunction
BIZENGRI can cause left ventricular dysfunction.
Left ventricular ejection fraction (LVEF) decrease has been observed with anti-HER2 therapies, including BIZENGRI. Treatment with BIZENGRI has not been studied in patients with a history of clinically significant cardiac disease or LVEF less than 50% prior to initiation of treatment.
In the eNRGy study, Grade 2 LVEF decrease (40%-50%; 10 – 19% drop from baseline) occurred in 2% of evaluable patients. Cardiac failure without LVEF decrease occurred in 1.7% of patients, including 1 (0.6%) fatal event.
Before initiating BIZENGRI, evaluate LVEF and monitor at regular intervals during treatment as clinically indicated. For LVEF of less than 45% or less than 50% with absolute decrease from baseline of 10% or greater which is confirmed, or in patients with symptomatic congestive heart failure (CHF), permanently discontinue BIZENGRI.

Embryo-Fetal Toxicity
Based on its mechanism of action, BIZENGRI can cause fetal harm when administered to a pregnant woman. No animal reproduction studies were conducted with BIZENGRI. In post marketing reports, use of a HER2-directed antibody during pregnancy resulted in cases of oligohydramnios manifesting as fatal pulmonary hypoplasia, skeletal abnormalities, and neonatal death. In animal models, studies have demonstrated that inhibition of HER2 and/or HER3 results in impaired embryo-fetal development, including effects on cardiac, vascular and neuronal development, and embryolethality. Advise patients of the potential risk to a fetus. Verify the pregnancy status of females of reproductive potential prior to the initiation of BIZENGRI. Advise females of reproductive potential to use effective contraception during treatment with BIZENGRI and for 2 months after the last dose.

ADVERSE REACTIONS
NRG1 Gene Fusion Positive Unresectable or Metastatic NSCLC
Serious adverse reactions occurred in 25% of patients with NRG1 gene fusion positive NSCLC who received BIZENGRI. Serious adverse reactions in ≥ 2% of patients included pneumonia (n=4) dyspnea and fatigue (n=2 each). Fatal adverse reactions occurred in 3 (3%) patients and included respiratory failure (n=2), and cardiac failure (n=1). Permanent discontinuation of BIZENGRI due to an adverse reaction occurred in 3% of patients. Adverse reactions resulting in permanent discontinuation of BIZENGRI included dyspnea, pneumonitis and sepsis (n=1 each).

On April 14, 2026 Mabwell (688062.SH), an innovation-driven biopharmaceutical company with a fully integrated industry chain, reported that 18F-FD4 (R&D code: SST001), an α-synuclein (α-syn) targeted PET tracer independently developed by its incubated company SynuSight Biotech, has recently been approved by the National Medical Products Administration (NMPA) to initiate a Phase I clinical trial.

The clinical trial to be initiated is a non-randomized, open-label study to be conducted at Huashan Hospital, Fudan University and the Affiliated Hospital of Jiangnan University. The study plans to enroll healthy volunteers, patients with multiple system atrophy (MSA), and patients with Parkinson’s disease (PD). The primary objectives are to evaluate the safety, tolerability, biodistribution, radiation dosimetry, and pharmacokinetics of SST001, thereby supporting subsequent clinical development.

Abnormal aggregation and deposition of α-syn protein are key pathological features of α-synucleinopathies such as PD and MSA. However, current clinical diagnosis still relies mainly on clinical symptom assessment and indirect functional imaging biomarkers. As an α-syn-specific PET molecular tracer validated through IIT (Investigator-Initiated Trial) studies, SST001 enables in vivo, real‑time, qualitative, and quantitative detection. It is expected to provide more objective and quantifiable imaging evidence for early diagnosis and disease subtyping of PD and MSA, as well as potential imaging support for subject screening and efficacy evaluation in clinical trials of related therapeutic drugs.

According to data from the Global Burden of Disease (GBD) Study 1990–2021, there were approximately 11.8 million PD patients worldwide in 2021, of which Chinese patients accounted for more than 40%. In China, the number of PD patients increased significantly from 651,800 in 1990 to 5.077 million in 2021, driven mainly by population aging. Although MSA is a rare disease, it progresses more rapidly and has a poorer prognosis, with a median survival of only 6 to 10 years, resulting in a significant disease burden.

Previously, SST001, partnering with XingImaging, has received high recognition from The Michael J. Fox Foundation for Parkinson’s Research (MJFF) and obtained a research grant of US$3.84 million, which will be specifically used to support its clinical research advancement in the United States. In January this year, SST001 received a Research IND clearance from the U.S. FDA, and clinical studies have been successfully initiated with the first subject dosed. Relevant data are being continuously collected. SST001 has now entered clinical stage in both China and the United States, entering a new phase of global development.
