Resectable MSI-H/dMMR colon cancer urgently requires effective neoadjuvant therapies to improve prognosis

MSI-H/dMMR colon cancer accounts for around 15% of all resectable colon cancer cases[ii]. Due to its unique biological characteristics, this class of tumor shows limited sensitivity to chemotherapy and generally responds poorly[iii]. In recent years, immune checkpoint inhibitors have demonstrated significant efficacy in advanced MSI-H/dMMR colon cancer, but a gap remains in the neoadjuvant setting. For locally advanced MSI-H/dMMR colon cancer, the current standard of care is direct surgery followed by adjuvant chemotherapy. Under this regimen, approximately 10%-30% of patients experience disease recurrence or metastasis after surgery, while chemotherapy-related toxicities may negatively affect quality of life[iv]. Thus in the neoadjuvant setting, there remains an urgent need for more effective therapies to improve outcomes for patients with locally advanced MSI-H/dMMR colon cancer.

The world’s first dual-IO neoadjuvant therapy: TABOSUN (ipilimumab N01 injection) combined with TYVYT (sintilimab injection) markedly enhances pathological complete response rates

Immune checkpoint blockade (ICB) therapy targeting PD-1 and CTLA-4 has transformed cancer treatment. The combination of DABOSUN (ipilimumab N01 injection) and TYVYT (sintilimab injection) as neoadjuvant therapy can significantly improve pathological complete response(pCR) rates and allow the majority of patients to avoid adjuvant chemotherapy.

Previously, results from a randomized, controlled Phase 1b trial evaluating ipilimumab N01 plus sintilimab as neoadjuvant treatment for MSI-H/dMMR colon cancer were published in the top-tier journal Cancer Cell[i].

As of June 17, 2025, 101 patients were enrolled and randomized to receive ipilimumab N01 plus sintilimab (n=52) or sintilimab alone (n=49).
In the per-protocol population, the pCR rate in the ipilimumab N01-plus-sintilimab arm was significantly higher than in the sintilimab-alone arm (80.0% vs 47.7%, p=0.0007).
With median follow-up of 21.4 months, no patient experienced disease recurrence.
Approval is based on results from the randomized, controlled, multicenter, pivotal Phase 3 clinical trial (NeoShot, NCT05890742), which evaluated the safety and efficacy of ipilimumab N01 combined with sintilimab as neoadjuvant therapy compared with direct radical surgery for MSI-H/dMMR colon cancer. The primary endpoints are pCR rate and event-free survival (EFS). Interim analysis by the Independent Data Monitoring Committee (IDMC) confirmed that the NeoShot trial met its primary endpoint.

As of November 28, 2024, among the first 50 patients in the treatment arm, 41 achieved pathological complete response after neoadjuvant treatment, yielding a pCR rate of 82%.
Neoadjuvant treatment with ipilimumab N01 combined with sintilimab did not significantly increase safety risks compared with direct surgery.
Detailed results will be presented at future academic conferences or published in academic journals.

The Principal Investigator of the NeoShot study, Academician of the Chinese Academy of Engineering, Prof. Ruihua Xu from Sun Yat-sen University Cancer Center, stated: "Achieving R0 resection remains challenging for certain patients with locally advanced colon cancer, who also face substantial surgical trauma and poor prognosis. Results from the FOxTROT study indicated that neoadjuvant chemotherapy provides limited benefit in MSI-H/dMMR colon cancer, with a pCR rate of only around 5%[v]. The NeoShot trial is the first randomized, controlled Phase 3 clinical trial to show promising efficacy of dual checkpoint inhibition as neoadjuvant therapy in MSI-H/dMMR colon cancer. Interim analysis suggests that ipilimumab N01 with sintilimab as short-term neoadjuvant treatment can lead to pathological complete response in 82% of treated patients. In addition, NeoShot Ph1b and Ph3 interim results both show the R0 resection under this regimen could reach 100% and spare patients from adjuvant chemotherapy. In NeoShot-1b, the dual-immunotherapy neoadjuvant regimen combining ipilimumab N01 and sintilimab significantly improved the pCR rate, which serves as a surrogate endpoint for long-term prognosis. Based on the existing data, this regimen shows promising potential to reduce recurrence risk and improve long-term survival outcomes. We look forward to observing continued reductions in recurrence with longer-term follow-up. The approval of this dual-immunotherapy regimen is expected to change clinical practice, fill a critical gap in neoadjuvant treatment of colon cancer and benefit more patients with MSI-H/dMMR colon cancer."

Dr. Hui Zhou, Chief R&D Officer (Oncology) of Innovent, stated: "There remains a substantial unmet clinical need for neoadjuvant therapies for stage IIB-III resectable MSI-H/dMMR colon cancer in China. Interim analysis has shown that the NeoShot trial met its primary endpoint. Through Innovent’s efficient and high-quality clinical development, ipilimumab N01 has become China’s first domestically developed innovative CTLA-4 inhibitor approved by the NMPA, offering a new treatment option for patients in China with stage IIB-III resectable MSI-H/dMMR colon cancer."

About Ipilimumab N01

Ipilimumab N01 (R&D code: IBI310) is a fully human monoclonal antibody injection independently developed by Innovent. Ipilimumab N01 specifically binds cytotoxic T lymphocyte-associated antigen 4 (CTLA-4), thereby blocking CTLA-4-mediated inhibition of T cell activity, promoting T cell activation and proliferation, improving tumor immune response, and achieving anti-tumor effects. [vi]

The NDA for ipilimumab N01 in combination with sintilimab as neoadjuvant treatment for stage IIB-III resectable microsatellite instability-high (MSI-H) or mismatch repair deficient (dMMR) colon cancer has recently been approved by the NMPA.

About Sintilimab

Sintilimab, marketed as TYVYT (sintilimab injection) in China, is a PD-1 immunoglobulin G4 monoclonal antibody co-developed by Innovent and Eli Lilly and Company. Sintilimab is a type of immunoglobulin G4 monoclonal antibody, which binds to PD-1 molecules on the surface of T-cells, blocks the PD-1 / PD-Ligand 1 (PD-L1) pathway, and reactivates T-cells to kill cancer cells.[vii]

In China, sintilimab has been approved and included in the updated NRDL for eight indications. The updated NRDL reimbursement scope for TYVYT (sintilimab injection) includes:

For the treatment of relapsed or refractory classic Hodgkin’s lymphoma after two lines or later of systemic chemotherapy;
For the first-line treatment of unresectable locally advanced or metastatic non-squamous non-small cell lung cancer lacking EGFR or ALK driver gene mutations;
For the treatment of patients with EGFR-mutated locally advanced or metastatic non-squamous non-small cell lung cancer who progressed after EGFR-TKI therapy;
For the first-line treatment of unresectable locally advanced or metastatic squamous non-small cell lung cancer;
For the first-line treatment of unresectable or metastatic hepatocellular carcinoma with no prior systematic treatment;
For the first-line treatment of unresectable locally advanced, recurrent or metastatic esophageal squamous cell carcinoma;
For the first-line treatment of unresectable locally advanced, recurrent or metastatic gastric or gastroesophageal junction adenocarcinoma; and
In combination with fruquintinib for the treatment of patients with advanced endometrial cancer with pMMR tumors that have failed prior systemic therapy and are not candidates for curative surgery or radiation.
The NDA for sintilimab’s ninth indication, in combination with ipilimumab N01 as neoadjuvant treatment for stage IIB-III resectable MSI-H/dMMR colon cancer is recently approved by the NMPA.

The NDA for sintilimab’s tenth indication, in combination with fruquintinib for the treatment of locally advanced or metastatic renal cell carcinoma who previously failed systematic treatment, has been accepted by the Center for Drug Evaluation (CDE) of NMPA.

In addition, two clinical studies of sintilimab have met their primary endpoints:

Phase 2 study of sintilimab monotherapy as second-line treatment of esophageal squamous cell carcinoma; and
Phase 3 study of sintilimab monotherapy as second-line treatment for squamous non-small cell lung cancer with disease progression following platinum-based chemotherapy.

Under the terms of the agreement, JCR receives exclusive rights to commercialise givinostat for the treatment of Duchenne muscular dystrophy (DMD) in Japan and will be responsible for the local execution of clinical development activities, as well as regulatory submissions.

Givinostat (marketed as Duvyzat in the US, UK and EU) is an orally administered histone deacetylase inhibitor developed by Italfarmaco to treat DMD, regardless of the underlying dystrophin gene mutation. It has obtained regulatory authorisation across several major markets, including the US, EU and the UK; it is currently not approved in Japan.

The agreement also establishes a broader strategic collaboration between the two companies to explore joint opportunities for the treatment of rare diseases.

"This partnership is a key milestone in our global strategy to expand access to givinostat and deepen our impact in rare diseases," said Antonio Nardi, Vice President and Head of Business & Portfolio Development of Italfarmaco. "JCR’s commitment to innovation, strong local expertise, and focus on patient-centred science make them an ideal partner for the expansion of our rare disease portfolios, not only in Japan, but also globally."

"Partnering with Italfarmaco is an important step for JCR as we enter the next phase of our growth and may be the first step in a long-lasting relationship between both companies that may extend into future research and development partnerships and cross-licensing opportunities," said Shin Ashida, Chairman, President and CEO of JCR Pharmaceuticals. "We remain dedicated to developing therapies for the rare disease community, and givinostat extends this commitment to an even broader group of patients with rare diseases in Japan."

Francesco De Santis, Chairman of Italfarmaco Group, added: "By joining forces with JCR, we are expanding access to an important DMD therapy for the Japanese Duchenne community and also laying the groundwork for future innovations in rare diseases. Together, we are committed to delivering meaningful solutions where they are needed most."

About Duchenne Muscular Dystrophy (DMD)
Duchenne muscular dystrophy (DMD) is a rare, progressive neuromuscular disorder caused by mutations in the dystrophin gene. These mutations prevent the production of functional dystrophin, causing the dystrophin-associated protein complex (DAPC) to break down. This makes muscle fibres more vulnerable to damage and increases histone deacetylase (HDAC) levels in the muscle cells, blocking the activation of important genes needed for muscle maintenance and repair. As a result, muscle fibres experience ongoing damage, leading to chronic inflammation and poor regeneration. Over time, muscle cells die and are replaced by scar tissue and fat.1-4 DMD primarily affects males, with symptoms typically appearing between the ages of two and five years. As the condition progresses, muscle weakness worsens, leading to difficulty walking and eventually loss of ambulation. Over time, the heart and respiratory muscles are also affected, which are the leading causes of premature death.5 DMD is one of the most severe and common forms of childhood muscular dystrophy, with a global birth incidence of approximately 1 in 5,050 boys.6 DMD affects an estimated 3,500 patients in Japan.7

About Givinostat
Givinostat (Duvyzat) was discovered through Italfarmaco’s research and development efforts in collaboration with Telethon and Duchenne Parent Project (Italy). Givinostat is the first nonsteroidal drug approved to treat patients with all genetic variants of DMD. It is a histone deacetylase (HDAC) inhibitor that works by targeting pathogenic processes to reduce inflammation and loss of muscle. Givinostat’s mechanism of action inhibits HDAC pathological overactivity in an effort to address the cascade of events leading to muscle damage, thereby counteracting the disease pathology and slowing down muscle degeneration.
