Pimicotinib Approved as Systemic Treatment in China for Tenosynovial Giant Cell Tumor

On December 22, 2025 Merck, a leading science and technology company, reported that following Priority Review, the China National Medical Products Administration (NMPA) has approved pimicotinib for the treatment of adult patients with symptomatic tenosynovial giant cell tumor (TGCT) for which surgical resection will potentially cause functional limitation or relatively severe morbidity. Pimicotinib, a colony stimulating factor-1 receptor (CSF-1R) inhibitor developed by Abbisko Therapeutics Co., Ltd., Shanghai, China, is the first Chemical Drug Class 1 approved in China for the treatment of TGCT.

"We are continuing to deliver on our commitment to improving the lives of patients with rare tumors with this first-in-the-world regulatory approval of pimicotinib," said Danny Bar-Zohar, CEO Healthcare and Member of the Executive Board of Merck. "This approval is a significant step forward in further strengthening our leadership in rare tumors, while offering patients the opportunity to change the course of their disease and help alleviate symptoms that impact their daily lives. We are now working to make pimicotinib available to patients in China as quickly as possible, as we continue to progress applications with regulatory authorities in additional markets."

TGCT is a rare, locally aggressive tumor of the joint leading to progressive swelling, stiffness and reduced mobility of the affected joint, significantly impacting daily activities and quality of life in the otherwise healthy population that it affects. If left untreated or in recurrent cases, TGCT can result in irreversible damage to the bone, joint and surrounding tissues. Historically TGCT may have been known by several different names, including pigmented villonodular synovitis (PVNS).

The approval of pimicotinib by the China NMPA is based on results from the global Phase 3 MANEUVER study, in which pimicotinib demonstrated the highest objective response rate (ORR) based on RECIST v1.1 seen in a Phase 3 trial of a systemic TGCT treatment, as well as meaningful improvements in clinical outcomes. At week 25, pimicotinib demonstrated a statistically significant improvement in the primary endpoint of ORR assessed by blinded independent review committee (BIRC) based on RECIST v1.1 compared with placebo at week 25 (54.0% vs. 3.2% for placebo; p<0.0001). Pimicotinib also demonstrated clinically meaningful and statistically significant improvements across secondary endpoints relevant to patients’ daily lives, improving relative range of motion (p=0.0003) and physical function measured by PROMIS-PF scale (p=0.0074) and reducing worst stiffness (p<0.0001) and worst pain (p<0.0001). These findings were presented at the 2025 ASCO (Free ASCO Whitepaper) Annual Meeting. Longer-term results presented at the ESMO (Free ESMO Whitepaper) Congress 2025 showed that with a median follow-up of 14.3 months, ORR per RECIST v1.1 increased considerably among patients treated with pimicotinib from the beginning of the study, to 76.2% (95% CI: 63.8, 86.0).

"Many people living with TGCT in China have faced a long and difficult journey due to the lack of approved options beyond surgery, which may not address the needs of patients whose tumors recur or are not amenable to resection," said Prof. Niu Xiaohui, Director of the Bone and Soft Tissue Tumour Diagnosis and Research Centre at Beijing Jishuitan Hospital. "With the approval of pimicotinib based on the results of the global MANEUVER study, healthcare professionals in China will soon have the opportunity to prescribe their patients an effective and well-tolerated systemic treatment option, offering a much-needed advance in how they manage this challenging condition."

In MANEUVER, pimicotinib was well-tolerated, with no evidence of cholestatic hepatotoxicity or hair/skin hypopigmentation. During the randomized, double-blind treatment phase of the trial, treatment-emergent adverse events (TEAEs) leading to treatment discontinuation occurred in one patient (1.6%) treated with pimicotinib; TEAEs leading to dose reduction occurred in 7.9% (n=5) of pimicotinib-treated patients.

"Pain and restricted mobility induced by TGCT impair patients’ daily functioning and impose huge psychological burden on them," commented Kevin Huang, Founder and President of Chinese Organization for Rare Disorders (CORD), and Founder and Secretary-General of the Hope For Rare Foundation. "Following the approval of pimicotinib in China, this systemic therapeutic regimen enables effective control of tumor progression and alleviation of clinical symptoms, bringing hope for patients who may regain the ability to join in activities deemed common by the most, such as climbing stairs, commuting to work, or playing with their children."

About MANEUVER

The pivotal global Phase 3 MANEUVER study is a three-part, randomized, double-blind, placebo-controlled study to assess the efficacy and safety of pimicotinib in patients with TGCT who require systemic therapy and have not received prior anti-CSF-1/CSF-1R therapy. The study is being conducted by Abbisko Therapeutics in China (n=45), Europe (n=28), and the US and Canada (n=21).

In the double-blind Part 1, 94 patients were randomized 2:1 to receive either 50 mg QD of pimicotinib (n=63) or placebo (n=31) for 24 weeks. The primary endpoint was objective response rate (ORR) at week 25, as measured by Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 by blinded independent central review (BICR) in the intent-to-treat (ITT) population. Secondary endpoints include ORR per tumor volume score (TVS), relative range of motion, stiffness by Numeric Rating Scale (NRS), pain by Brief Pain Inventory (BPI), and physical function measured by Patient-Reported Outcomes Measurement Information System (PROMIS-PF).

After the double-blind Part 1, eligible patients could continue to the open-label Part 2 for up to 24 weeks of further treatment. Patients who completed Part 2 could then enter the open-label extension phase (Part 3) for extended treatment and safety follow-up.

About pimicotinib (ABSK021)

Pimicotinib, developed by Abbisko Therapeutics, is a novel, orally administered, highly selective and potent small-molecule inhibitor of CSF-1R. It has been granted breakthrough therapy designation (BTD) for the treatment of inoperable TGCT by the U.S. Food and Drug Administration (FDA), and priority medicine (PRIME) designation from the European Medicines Agency (EMA). Merck holds worldwide commercialization rights for pimicotinib.

Chugai Obtains Regulatory Approval for Tecentriq for the Additional Indication of Thymic Carcinoma, a Rare Disease

On December 22, 2025 Chugai Pharmaceutical Co., Ltd. (TOKYO: 4519) reported that it obtained approval from the Ministry of Health, Labour and Welfare (MHLW) for the anti-cancer agent/humanized anti-PD-L1 monoclonal antibody Tecentriq Intravenous Infusion [generic name: atezolizumab (genetical recombination)] for an additional indication of unresectable thymic carcinoma. Tecentriq received orphan drug designation for this indication from the MHLW on March 31, 2025. Chugai subsequently filed an application on May 14, 2025, which underwent Priority Review.

"We are very pleased to be able to deliver Tecentriq as a new treatment option for unresectable thymic carcinoma. Effective treatment options for this disease are limited, and new therapies have been highly anticipated. We will continue our efforts to provide information on the proper use of Tecentriq to contribute to the patients with thymic carcinoma." said Chugai’s President and CEO, Dr. Osamu Okuda.

This approval is based on the results from the investigator-initiated phase II MARBLE study conducted in Japan, which evaluated the efficacy and safety of Tecentriq in combination with carboplatin and paclitaxel as first-line treatment for patients with unresectable thymic carcinoma.

Chugai Pharmaceutical, a leading company in the oncology field, remains committed to addressing unmet medical needs in cancer treatment with innovative medicines, supporting patients and healthcare professionals.

About MARBLE study1
MARBLE study (jRCT2031220144) is a Japanese Phase II, multicenter, open-label, single-arm study led by investigators to evaluate the efficacy and safety of Tecentriq in combination with carboplatin and paclitaxel in patients aged 20 years or older with unresectable or advanced recurrent thymic carcinoma. The study evaluated safety and efficacy in 48 patients. The primary endpoint was overall response rate, and secondary endpoints included progression-free survival, overall survival, and safety.

About thymic carcinoma
Thymic carcinoma is a type of thymic epithelial tumor that originates from the thymic epithelium, which plays an important role in T-lymphocyte maturation, and is characterized by cellular atypia. The annual incidence in Japan is estimated to be 0.29 per 100,000 people2. The prognosis for unresectable cases is poor, highlighting the need for new therapeutic options.

About Tecentriq
Tecentriq is a cancer immune checkpoint inhibitor targeting PD-L1, which is a protein expressed on tumor and tumor-infiltrating immune cells. PD-L1 blocks T cell activity by binding with PD-1 and B7.1 receptors on the T cell surface. By inhibiting PD-L1, Tecentriq may enable the activation of T cells and boost immune response against cancer cells. In Japan, Tecentriq was launched in April 2018 and has obtained approval for 6 tumour types (extensive-stage small cell lung cancer, non-small cell lung cancer, breast cancer, hepatocellular carcinoma, alveolar soft part sarcoma, and extranodal NK/T-cell lymphoma, nasal type).

Enhertu granted Breakthrough Therapy Designation in the US as post-neoadjuvant therapy for patients with HER2-positive early breast cancer

On December 22, 2025 AstraZeneca and Daiichi Sankyo reported that Enhertu (trastuzumab deruxtecan) has been granted Breakthrough Therapy Designation (BTD) in the US for adult patients with HER2-positive early breast cancer with residual invasive disease in the breast and/or axillary lymph nodes after neoadjuvant treatment and high risk of disease recurrence.

The Food and Drug Administration (FDA) BTD accelerates the development and regulatory review of potential new medicines intended to treat a serious condition and address a significant unmet medical need.

The FDA granted this BTD based on results from the DESTINY-Breast05 Phase III trial presented in a Presidential Symposium at the 2025 European Society for Medical Oncology (ESMO) (Free ESMO Whitepaper) Congress and subsequently published in The New England Journal of Medicine.

Susan Galbraith, Executive Vice President, Oncology Haematology R&D, AstraZeneca, said: "For patients with residual disease after neoadjuvant treatment, the post-neoadjuvant setting represents a critical opportunity to reduce the risk of recurrence and prevent progression to metastatic disease. This Breakthrough Therapy Designation highlights the impressive clinical benefit of Enhertu over the current standard of care and underscores its potential to become an important treatment option in the post-neoadjuvant setting."

Ken Takeshita, Global Head, R&D, Daiichi Sankyo, said: "This tenth Breakthrough Therapy Designation reinforces how Enhertu continues to deliver transformational results that advance the treatment of breast cancer. We look forward to working with the FDA with the goal of bringing Enhertu to the post-neoadjuvant setting of HER2-positive early breast cancer, as DESTINY-Breast05 clearly demonstrated that Enhertu may help halt invasive disease recurrence over the current standard of care, resulting in potentially more patients achieving a cure."

DESTINY-Breast05 is the second positive trial of Enhertu in early breast cancer in 2025. The first trial, DESTINY-Breast11, evaluating patients with high-risk HER2-positive disease in the neoadjuvant setting, is currently under review by the FDA.

Enhertu is a specifically engineered HER2-directed DXd antibody drug conjugate (ADC) discovered by Daiichi Sankyo and being jointly developed and commercialised by AstraZeneca and Daiichi Sankyo.

Notes

Post-neoadjuvant Treatment for HER2-Positive Early Breast Cancer
Breast cancer is the second most common cancer and one of the leading causes of cancer-related deaths worldwide.1 More than two million breast cancer cases were diagnosed in 2022, with more than 665,000 deaths globally.1

HER2 is a tyrosine kinase receptor growth-promoting protein expressed on the surface of many types of tumours including breast cancer.2 HER2 protein overexpression may occur as a result of HER2 gene amplification and is often associated with aggressive disease and poor prognosis in breast cancer.2 Approximately one in five cases of breast cancer are considered HER2 positive.3

For patients with HER2-positive early breast cancer, achieving pathologic complete response (pCR) with neoadjuvant treatment is the earliest indicator of improved long-term survival.4 However, approximately half of patients who receive neoadjuvant treatment do not experience pCR, putting them at increased risk of disease recurrence.5-9

Despite receiving additional treatment with T-DM1 for residual disease in the post-neoadjuvant setting, approximately 20% of patients still experience invasive disease or death, with no reduction in the risk of central nervous system recurrence.10-11 Once patients are diagnosed with metastatic disease, the five-year survival rate drops from nearly 90% to approximately 30%.12

Post-neoadjuvant therapy represents a key opportunity to minimise the risk of recurrence and prevent progression to metastatic disease for patients with residual disease. New treatment options are needed in the early breast cancer setting to help reduce the likelihood of disease progression and improve long-term outcomes for more patients.13,14

DESTINY-Breast05
DESTINY-Breast05 is a global, multicentre, randomised, open-label, Phase III trial evaluating the efficacy and safety of Enhertu (5.4 mg/kg) versus trastuzumab emtansine (T-DM1) in patients with HER2-positive early breast cancer with residual invasive disease in breast or axillary lymph nodes following neoadjuvant therapy and a high risk of recurrence. High risk of recurrence was defined as presentation with inoperable cancer (prior to neoadjuvant therapy) or pathologically positive axillary lymph nodes following neoadjuvant therapy.

The primary endpoint of DESTINY-Breast05 is investigator-assessed invasive disease-free survival (IDFS). IDFS is defined as the time from randomisation until first invasive local, axillary or distant recurrence or death from any cause. The key secondary endpoint is investigator-assessed disease-free survival. Other secondary endpoints include overall survival, distant recurrence-free interval, brain metastases-free interval and safety.

DESTINY-Breast05 enrolled 1,635 patients in Asia, Europe, North America, Oceania and South America. For more information about the trial, visit ClinicalTrials.gov.

Enhertu
Enhertu is a HER2-directed ADC. Designed using Daiichi Sankyo’s proprietary DXd ADC Technology, Enhertu is the lead ADC in the oncology portfolio of Daiichi Sankyo and the most advanced programme in AstraZeneca’s ADC scientific platform. Enhertu consists of a HER2 monoclonal antibody attached to a number of topoisomerase I inhibitor payloads (an exatecan derivative, DXd) via tetrapeptide-based cleavable linkers.

Enhertu (5.4mg/kg) in combination with pertuzumab is approved in the US as a 1st-line treatment for adult patients with unresectable or metastatic HER2-positive (IHC 3+ or ISH+) breast cancer, as determined by an FDA-approved test based on the results from the DESTINY-Breast09 trial.

Enhertu (5.4mg/kg) is approved in more than 90 countries/regions worldwide for the treatment of adult patients with unresectable or metastatic HER2-positive (IHC 3+ or ISH+) breast cancer who have received a prior anti-HER2-based regimen, either in the metastatic setting or in the neoadjuvant or adjuvant setting, and have developed disease recurrence during or within six months of completing therapy based on the results from the DESTINY-Breast03 trial.

Enhertu (5.4mg/kg) is approved in more than 85 countries/regions worldwide for the treatment of adult patients with unresectable or metastatic HER2-low (IHC 1+ or IHC 2+/ISH-) breast cancer who have received a prior systemic therapy in the metastatic setting or developed disease recurrence during or within six months of completing adjuvant chemotherapy based on the results from the DESTINY-Breast04 trial.

Enhertu (5.4mg/kg) is approved in more than 55 countries/regions worldwide for the treatment of adult patients with unresectable or metastatic hormone receptor (HR)-positive, HER2-low (IHC 1+ or IHC 2+/ ISH-) or HER2-ultralow (IHC 0 with membrane staining) breast cancer, as determined by a locally or regionally approved test, that have progressed on one or more endocrine therapies in the metastatic setting based on the results from the DESTINY-Breast06 trial.

Enhertu (5.4mg/kg) is approved in more than 60 countries/regions worldwide for the treatment of adult patients with unresectable or metastatic non-small cell lung cancer (NSCLC) whose tumours have activating HER2 (ERBB2) mutations, as detected by a locally or regionally approved test, and who have received a prior systemic therapy based on the results from the DESTINY-Lung02 and/or DESTINY-Lung05 trials. Continued approval in China and the US for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial.

Enhertu (6.4mg/kg) is approved in more than 70 countries/regions worldwide for the treatment of adult patients with locally advanced or metastatic HER2-positive (IHC 3+ or IHC 2+/ISH+) gastric or gastroesophageal junction (GEJ) adenocarcinoma who have received a prior trastuzumab-based regimen based on the results from the DESTINY-Gastric01, DESTINY-Gastric02 and/or DESTINY-Gastric06 trials. Continued approval in China for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial.

Enhertu (5.4mg/kg) is approved in more than 10 countries/regions worldwide for the treatment of adult patients with unresectable or metastatic HER2-positive (IHC 3+) solid tumours who have received prior systemic treatment and have no satisfactory alternative treatment options based on efficacy results from the DESTINY-PanTumor02, DESTINY-Lung01 and DESTINY-CRC02 trials. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial.

Enhertu development programme
A comprehensive global clinical development programme is underway evaluating the efficacy and safety of Enhertu as a monotherapy, in combination or sequentially with other cancer medicines across multiple HER2-targetable cancers.

Update on LATIFY Phase III trial of ceralasertib plus Imfinzi in previously treated advanced non-small cell lung cancer

On December 22, 2025 Astrazeneca reported The LATIFY Phase III trial of ceralasertib in combination with Imfinzi (durvalumab) did not meet the primary endpoint of overall survival (OS) versus standard-of-care docetaxel in patients with locally advanced or metastatic non-small cell lung cancer (NSCLC). The trial evaluated patients without actionable genomic alterations (AGAs) whose disease progressed on or after prior immunotherapy and platinum-based chemotherapy.

Susan Galbraith, Executive Vice President, Oncology Haematology R&D, AstraZeneca, said: "Our goal in the LATIFY trial was to reinvigorate the immune response of patients with lung cancer whose tumours stopped responding to available therapies by combining ATR inhibition with immunotherapy. While we are disappointed by this result, we remain committed to pioneering new medicines to address the urgent need to improve outcomes for patients with lung cancer through our industry-leading portfolio."

The combination of ceralasertib and Imfinzi was generally well tolerated, and the safety profile was consistent with the known profiles of each individual medicine, with no new safety concerns identified. These data will be presented at a forthcoming medical meeting.

Notes

NSCLC
Lung cancer is the leading cause of cancer death among both men and women, accounting for about one-fifth of all cancer deaths.1 Lung cancer is broadly split into small cell lung cancer (SCLC) or NSCLC, the latter accounting for about 80-85% of cases.2-3 Patients are most commonly diagnosed with metastatic disease, when the tumour has spread outside the lung.4 Approximately 12% of people with metastatic NSCLC will still be alive five years after diagnosis.5

LATIFY
LATIFY is a randomised, open-label, multi-centre, global Phase III trial of ceralasertib plus Imfinzi in patients with locally advanced or metastatic NSCLC without AGAs, and whose disease has progressed on or after prior anti-PD-(L)1 therapy and platinum-based chemotherapy. Patients were randomised 1:1 to receive ceralasertib 240mg twice daily oral tablets for seven days in combination with a 1,500mg fixed dose of Imfinzi on day eight every four weeks or docetaxel every three weeks until disease progression, unacceptable toxicity, withdrawal of consent or a discontinuation criterion was met.

The trial enrolled 594 patients across more than 20 countries. The primary endpoint is OS and secondary endpoints include progression-free survival, objective response rate, duration of response, time to response, disease control rate and patient reported outcomes.

Ceralasertib
Ceralasertib is an oral, potent and selective inhibitor of the ATR kinase, which is crucial for DNA damage responses and cell survival. Ceralasertib acts on the tumour microenvironment, moving it from a suppressed immune state into an activated state when combined with immunotherapy.

Imfinzi
Imfinzi (durvalumab) is a human monoclonal antibody that binds to the PD-L1 protein and blocks the interaction of PD-L1 with the PD-1 and CD80 proteins, countering the tumour’s immune-evading tactics and releasing the inhibition of immune responses.

In lung cancer, Imfinzi is the global standard of care based on OS in the curative-intent setting of unresectable, Stage III NSCLC in patients whose disease has not progressed after chemoradiotherapy (CRT). Additionally, Imfinzi is approved as a perioperative treatment in combination with neoadjuvant chemotherapy in resectable NSCLC, and in combination with a short course of Imjudo (tremelimumab) and chemotherapy for the treatment of metastatic NSCLC. Imfinzi is also approved for limited-stage SCLC in patients whose disease has not progressed following concurrent platinum-based CRT; and in combination with chemotherapy for the treatment of extensive-stage SCLC.

In addition to its indications in lung cancers, Imfinzi is also approved in combination with chemotherapy in locally advanced or metastatic biliary tract cancer and in combination with Imjudo in unresectable hepatocellular carcinoma (HCC). Imfinzi is also approved as a monotherapy in unresectable HCC in Japan and the European Union (EU), and in resectable, early-stage and locally advanced gastric and gastroesophageal junction cancers in the US.

Perioperative Imfinzi in combination with neoadjuvant chemotherapy is approved for muscle-invasive bladder cancer. In May 2025, Imfinzi added to Bacillus Calmette-Guérin induction and maintenance therapy met the primary endpoint of disease-free survival for patients with high-risk non-muscle-invasive bladder cancer in the POTOMAC Phase III trial.

Imfinzi in combination with chemotherapy followed by Imfinzi monotherapy is approved as a 1st-line treatment for primary advanced or recurrent endometrial cancer (mismatch repair deficient disease only in the US and EU). Imfinzi in combination with chemotherapy followed by Lynparza (olaparib) and Imfinzi is approved for patients with mismatch repair proficient advanced or recurrent endometrial cancer in the EU and Japan.

Since the first approval in May 2017, more than 414,000 patients have been treated with Imfinzi. As part of a broad development programme, Imfinzi is being tested as a single treatment and in combinations with other anti-cancer treatments for patients with NSCLC, bladder cancer, breast cancer, ovarian cancer and several gastrointestinal cancers.
