Pirtobrutinib is a highly selective kinase inhibitor that utilizes a novel non-covalent binding mechanism to extend the benefit of targeting the BTK pathway in CLL/SLL patients previously treated with a covalent BTK inhibitor (ibrutinib, acalabrutinib, or zanubrutinib).[1],[2] Pirtobrutinib received approval from the U.S. FDA in January 2023 as a non‑covalent (reversible) BTK inhibitor. In October 2024, pirtobrutinib was approved in China as a monotherapy for the treatment of adult patients with relapsed or refractory mantle cell lymphoma (MCL) who have previously received at least two prior systemic therapies, including a Bruton’s tyrosine kinase (BTK) inhibitor.

The approval of this new indication is based on results from the international, multicenter, randomized, Phase 3 BRUIN CLL‑321 study. BRUIN CLL‑321 is the world’s first randomized Phase 3 trial conducted in patients with CLL/SLL who had previously been treated with a covalent BTK inhibitor (cBTKi). The study enrolled a total of 238 patients and evaluated the efficacy and safety of pirtobrutinib monotherapy versus investigator’s choice of IdelaR (idelalisib plus rituximab) or BR (bendamustine plus rituximab). The results demonstrated that pirtobrutinib significantly prolonged median progression‑free survival (PFS) compared with the investigator’s choice regimen (14.0 months vs 8.7 months; hazard ratio [HR] = 0.54). In addition, the discontinuation rate due to treatment‑related adverse events was lower with pirtobrutinib (5.2% vs 21.1%), further supporting its efficacy and tolerability advantages in patients previously treated with a covalent BTK inhibitor.[3]

Professor Lu-Gui Qiu, Principal Investigator of the BRUIN CLL‑321 study in China, Institute of Hematology & Blood Diseases Hospital, Chinese Academy of Medical Sciences, stated, "BTK inhibitors have become the preferred first‑ or second‑line treatment for patients with CLL/SLL, yet some patients still experience disease progression and have a poor prognosis. Studies have shown that the median overall survival for patients after discontinuing a covalent BTK inhibitor is only about 22.7 months.[4] Therefore, there is an urgent clinical need for new treatment. As a next‑generation, non‑covalent and reversible BTK inhibitor, pirtobrutinib represents an important advancement for patients with relapsed or refractory CLL. The BRUIN CLL‑321 study demonstrated its therapeutic potential in CLL/SLL. We believe it will offer an important treatment option for patients with CLL/SLL in China and help meet the needs of long‑term disease management in the future."

Dr. Li Wang, Lilly Corporate Senior Vice President, Head of Lilly China Drug Development & Medical Affairs Center, states, "The approval of pirtobrutinib for the CLL/SLL indication in China marks an important milestone in the treatment journey for Chinese CLL/SLL patients. It means that patients who continue to experience disease progression after covalent BTK inhibitor therapy can now gain timely access to this globally innovative treatment option. Supported by the efficacy and safety demonstrated in the BRUIN CLL‑321 study, we are pleased to offer a new therapeutic choice for CLL/SLL patient population with significant unmet medical needs in China. Looking ahead, Lilly will remain committed to accelerating the introduction of cutting‑edge therapies to help patients with hematologic malignancies in China achieve longer and better quality of survival. This is our enduring commitment to patients in China."

Dr. Hui Zhou, Chief R&D Officer of Oncology in Innovent, stated, "Jaypirca (pirtobrutinib) is a next-generation, non-covalent (reversible) BTK inhibitor. It offers a novel treatment option for patients who have previously received covalent BTK inhibitor therapy. The approval in China for CLL/SLL represents a significant breakthrough in this field, which ensures that CLL/SLL patients in China have timely access to this global therapeutic innovation. We will fully leverage Innovent’s leading brand presence and commercialization capabilities in oncology, to accelerate the accessibility of this innovative therapy, thereby benefiting more cancer patients in need."

About BRUIN CLL-321
BRUIN CLL-321 is a Phase 3, randomized, open-label study of Jaypirca versus investigator’s choice of idelalisib plus rituximab (IdelaR) or bendamustine plus rituximab (BR) in covalent Bruton tyrosine kinase (BTK) inhibitor pre-treated patients with relapsed and refractory chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL). The trial enrolled 238 patients, who were randomized 1:1 to receive Jaypirca (200 mg orally, once daily) or investigator’s choice of either IdelaR or BR per labeled doses. This trial’s primary endpoint is progression-free survival (PFS) per 2018 International Workshop on Chronic Lymphocytic Leukemia (iwCLL) criteria, as assessed by blinded independent review committee (IRC). Secondary endpoints include PFS, as assessed by investigator; overall response rate (ORR) and duration of response (DoR); event-free survival; overall survival (OS) and time to next treatment (TTNT); safety and tolerability; and patient-reported outcomes (PRO).

About Jaypirca (pirtobrutinib)
Jaypirca (pirtobrutinib, formerly known as LOXO-305) (pronounced jay-pihr-kaa) is a highly selective (300 times more selective for BTK versus 98% of other kinases tested in preclinical studies), non-covalent (reversible) inhibitor of the enzyme BTK.[2] BTK is a validated molecular target found across numerous B-cell leukemias and lymphomas including mantle cell lymphoma (MCL) and chronic lymphocytic leukemia (CLL).[5],[6]

In China, pirtobrutinib was developed by Eli Lilly and Company and is commercialized in mainland China by Innovent Biologics.

About Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma
Chronic lymphocytic leukemia (CLL) and small lymphocytic lymphoma (SLL) are forms of slow-growing non-Hodgkin lymphoma that develop from white blood cells known as lymphocytes.[7] In China, chronic lymphocytic leukemia (CLL) represents approximately 6%–7% of non-Hodgkin lymphoma cases.[8] SLL is identical to CLL from a pathologic and immunophenotypic standpoint, with the main difference between them being the location of the cancer cells. In CLL, the cancer cells are present in the blood, and in SLL, the cancer cells are found in the lymph nodes.

Zurletrectinib has also been included in the "SPARK Program" by the CDE, a pilot initiative to encourage the development of pediatric anti-tumor drugs.

In December 2025, zurletrectinib received approval for the treatment of adult and adolescent patients (aged 12 years and older) with solid tumors harboring NTRK gene fusions in China. In the registrational clinical trial for patients with NTRK fusion-positive solid tumors, zurletrectinib demonstrated outstanding efficacy and a favorable safety profile. The study results showed an objective response rate (ORR) of 89.1%, a disease control rate (DCR) of 96.4%, and 24-month progression-free survival (PFS) and overall survival (OS) rates of 77.4% and 90.8% respectively.

In October 2025, the data from the Phase I/II clinical trial of zurletrectinib for the treatment of pediatric and adolescent patients with advanced solid tumors were released at the Congress of International Society of Pediatric Oncology (SIOP) 2025 as an oral presentation. Zurletrectinib demonstrated a well-tolerated safety profile and promising antitumor activity in pediatric/adolescent patients with NTRK/ROS1-altered solid tumors. The results highlight zurletrectinib’s strong potential as a next-generation therapy for NTRK/ROS1-driven malignancies, with the ability to overcome resistance to first-generation TRK inhibitors.

NTRK fusion genes occur in various types of adult and pediatric tumors. In some rare tumors, such as salivary gland carcinoma, secretory breast cancer, and infantile fibrosarcoma, the incidence of NTRK gene fusion exceeds 90%1. It is estimated that there are about 6,500 new cases of NTRK fusion-positive solid tumors diagnosed in China each year. There are significant unmet clinical needs in this area due to the lack of effective treatment options.

At a pre-specified interim analysis with a median follow-up of 29.0 months (range, 19.3-49.2), WELIREG plus LENVIMA demonstrated a statistically significant and clinically meaningful improvement in the primary endpoint of progression-free survival (PFS), reducing the risk of disease progression or death by 30% (HR=0.70 [95% CI, 0.59-0.84]; p=0.00007) compared to cabozantinib. For WELIREG plus LENVIMA, the median PFS was 14.8 months (95% CI, 11.2-16.6) versus 10.7 months (95% CI, 9.2-11.1) for cabozantinib. A trend toward improvement in overall survival (OS), the trial’s other primary endpoint, was also observed for WELIREG plus LENVIMA (HR=0.85 [95% CI, 0.68-1.05]; p=0.06075). The median OS was 34.9 months (95% CI, 27.5-NR) for WELIREG plus LENVIMA versus 27.6 months (95% CI, 24.0-31.4) for cabozantinib. The trial is continuing, and OS will be evaluated at a subsequent analysis per the clinical trial protocol.

Based on data from the LITESPARK-011 trial, the U.S. Food and Drug Administration (FDA) has accepted two supplemental New Drug Applications (sNDA) for review seeking approval for WELIREG plus LENVIMA for the treatment of adult patients with advanced RCC with a clear cell component following a PD-1 or PD-L1 inhibitor. The FDA set a Prescription Drug User Fee Act (PDUFA), or target action date, of October 4, 2026 for both the WELIREG and LENVIMA sNDAs. Merck and Eisai will also discuss these data with regulatory authorities worldwide to support potential submissions outside the United States.

"Choosing the right treatment for patients with advanced renal cell carcinoma after immunotherapy has been an ongoing challenge, and treatment options in this setting had not previously been evaluated against a current standard of care tyrosine kinase inhibitor in a Phase 3 trial," said Dr. Robert Motzer, Principal Investigator and Genitourinary Medical Oncologist, Memorial Sloan Kettering Cancer Center. "The LITESPARK-011 study demonstrated a 30% reduction in the risk of disease progression or death with belzutifan plus lenvatinib compared to cabozantinib, and 52.6% of patients experienced a response to treatment. These findings mark a critical step forward for these patients."

"The LITESPARK-011 trial highlights the potential of this first-of-its-kind combination regimen to deliver a meaningful benefit for patients with advanced renal cell carcinoma whose disease progresses after PD-1/L1 therapy," said Dr. M. Catherine Pietanza, Vice President, Global Clinical Development, Merck Research Laboratories. "These WELIREG plus LENVIMA data demonstrate important progress for patients with advanced renal cell carcinoma and reinforce our commitment to improving the lives of patients through innovative treatment strategies."

"The LITESPARK-011 results reinforce LENVIMA’s established role in renal cell carcinoma and highlight the potential of this novel combination to address an area of significant unmet need," said Dr. Corina Dutcus, Senior Vice President, Oncology Global Clinical Development Lead at Eisai. "The acceptance of this regulatory filing is an important milestone, and we remain committed to working toward approval to bring this option to patients as soon as possible. We are grateful to the patients, their families, and the investigators, whose dedication made this research possible."

Additional findings

Data for objective response rate (ORR) and duration of response (DOR), two key secondary endpoints, were also reported. At the first interim analysis with a median follow-up of 19.6 months (range, 9.9-39.8), WELIREG plus LENVIMA met ORR, demonstrating a statistically significant improvement compared to cabozantinib. A confirmed ORR of 52.6% (95% CI, 47.3-57.7) was observed for WELIREG plus LENVIMA versus 39.6% (95% CI, 34.6-44.8) for cabozantinib. At the second interim analysis with a median follow-up of 29.0 months, the median DOR was 23.0 months (95% CI, 2.0-44.3+) for WELIREG plus LENVIMA versus 12.3 months (95% CI, 1.8+-35.9+) for cabozantinib.

WELIREG plus LENVIMA was administered to 370 patients and cabozantinib was administered to 371 patients. Grade ≥3 treatment-related adverse events (TRAEs) occurred in 71.6% of patients receiving WELIREG plus LENVIMA versus 65.8% of patients receiving cabozantinib. Adverse events led to the discontinuation of 11.1% of patients receiving WELIREG plus LENVIMA versus 11.3% of patients receiving cabozantinib, respectively. Serious adverse events were observed in 51.6% of patients receiving WELIREG plus LENVIMA versus 43.9% of patients receiving cabozantinib, and AEs led to death in 5.4% of patients (two were treatment-related: thrombotic microangiopathy [n=1] and pneumonitis [n=1]) versus 3.2% (one was treatment-related: hemoptysis [n=1]) of patients, respectively.

LITESPARK-011 is part of a comprehensive late-stage clinical development program for WELIREG comprised of several Phase 2 and Phase 3 trials in pheochromocytoma and paraganglioma, von Hippel-Lindau disease-associated neoplasms and RCC.

The Phase 3 LITESPARK-012 trial is evaluating the addition of WELIREG to KEYTRUDA (pembrolizumab), Merck’s anti-PD-1 therapy, plus LENVIMA in the first-line advanced RCC disease setting.

WELIREG is approved in the U.S., European Union (EU), Japan and other countries for the treatment of adult patients with advanced clear cell RCC following a PD-1/PD-L1 inhibitor and 1-2 VEGF-TKIs based on results from the Phase 3 LITESPARK-005 trial.

KEYTRUDA plus LENVIMA is approved in the U.S., the EU, Japan and other countries for the treatment of advanced RCC. Lenvatinib is approved as KISPLYX for advanced RCC in the EU.

LENVIMA in combination with everolimus is approved in the U.S., EU and other regions for the treatment of adult patients with advanced RCC following one prior anti-angiogenic therapy.

Dr. Motzer has provided consulting and advisory services for Merck and Eisai.

At the first pre-specified interim analysis (median follow-up of 28.4 months [range, 15.0-40.1 months]), KEYTRUDA plus WELIREG given in the adjuvant setting significantly improved disease-free survival (DFS), the study’s primary endpoint, reducing the risk of disease recurrence or death by 28% (HR=0.72 [95% CI 0.59-0.87]; p=0.0003) compared to KEYTRUDA plus placebo. Median DFS was not reached in either arm; the estimated 24-month DFS rate was 80.7% (95% CI, 77.7-83.2) for the KEYTRUDA plus WELIREG arm and was 73.7% (95% CI, 70.6-76.6) for the KEYTRUDA plus placebo arm. As previously reported, the trial will continue to evaluate overall survival (OS), a key secondary endpoint.

"Approximately 40% of patients with renal cell cancer may experience tumor growth after initial treatment. Results from LITESPARK-022 mark an important step forward for certain patients with renal cell cancer, showing a significant reduction in the risk of disease recurrence or death compared to pembrolizumab alone," said Dr. Toni K. Choueiri, director, Lank Center for Genitourinary Oncology, Dana-Farber Cancer Institute and Jerome and Nancy Kohlberg professor of medicine, Harvard Medical School. "The combination of pembrolizumab and belzutifan is the first ever regimen in the adjuvant setting for renal cell cancer to demonstrate an improvement in disease-free survival over pembrolizumab monotherapy, positioning this regimen to potentially reshape clinical practice."

"LITESPARK-022 is a critical part of our comprehensive RCC clinical development program, and the Phase 3 results presented at ASCO (Free ASCO Whitepaper) GU underscore the importance of KEYTRUDA and WELIREG in helping to treat patients with certain types of renal cell carcinoma," said Dr. M. Catherine Pietanza, vice president, Global Clinical Development, Merck Research Laboratories. "These findings represent the first positive Phase 3 data for WELIREG in earlier stages of disease, as well as the first positive Phase 3 results for a HIF‑2α inhibitor and immunotherapy combination, reinforcing our commitment to exploring novel treatment approaches to improve upon established treatment paradigms for patients in need."

The safety profile of KEYTRUDA plus WELIREG was consistent with that observed in previously reported studies for both agents; no new safety signals were observed. Of patients enrolled, 69.5% of those in the KEYTRUDA plus WELIREG arm and 71.1% of those in the KEYTRUDA plus placebo arm completed the assigned treatment. Among treated patients, Grade ≥3 treatment-emergent adverse events (TEAEs) occurred in 52.1% of patients who received KEYTRUDA plus WELIREG and 30.2% of patients who received KEYTRUDA plus placebo. The most common Grade ≥3 TEAEs were anemia (12.1% versus 0.5%), increased alanine aminotransferase (ALT) (6.4% versus 2.0%) and hypoxia (4.6% versus 0%). Grade 5 treatment-emergent (1.1% versus 1.2%) and treatment-related adverse events (0.3% versus 0.3%) were similar between treatment arms.

Based on data from the LITESPARK-022 trial, the U.S. Food and Drug Administration (FDA) has accepted for priority review supplemental applications seeking approval of WELIREG in combination with KEYTRUDA or KEYTRUDA QLEX (pembrolizumab and berahyaluronidase alfa-pmph) for the adjuvant treatment of adult patients with RCC with a clear cell component with increased risk of recurrence following nephrectomy. The FDA has set a Prescription Drug User Fee Act (PDUFA), or target action date, of June 19, 2026 for the WELIREG sNDA and the KEYTRUDA and KEYTRUDA QLEX sBLAs. Merck will also discuss these data with global regulatory authorities.

KEYTRUDA is approved for the adjuvant treatment of certain patients with RCC in the U.S., Canada, European Union (EU), Japan and other countries worldwide based on data from KEYNOTE-564.

WELIREG is approved in over 45 countries including the U.S., Canada, EU, and Japan for the treatment of adult patients with advanced RCC following a PD-1/PD-L1 inhibitor and 1-2 VEGF-TKIs based on results from the Phase 3 LITESPARK-005 trial.

Merck has an industry-leading clinical development program in RCC, leveraging multiple approved therapeutic options across multiple settings, including adjuvant and advanced disease.
