A Chinese medical team has made a significant breakthrough in the treatment of dMMR (deficient mismatch repair) metastatic colorectal cancer. Recently, their latest research findings were published in the *Med* journal, a subsidiary of *Cell*, offering new treatment hope for patients with advanced colorectal cancer.

The study revealed that the combination of PD-1 antibody immunotherapy with COX inhibitors, drugs commonly used for anti-inflammatory treatment, significantly improved treatment effectiveness. This innovative strategy could substantially increase survival chances for patients with advanced colorectal cancer.

Colorectal cancer is the second most common cancer in China, and its incidence is on the rise. While PD-1 antibody immunotherapy has brought hope to some patients, its success rate is only 45%. Approximately 30% of dMMR metastatic colorectal cancer patients are resistant to PD-1 treatment. Therefore, the Chinese team explored combining PD-1 immunotherapy with COX inhibitors (such as celecoxib and aspirin) to overcome this resistance.

The team’s Phase 2 clinical trial yielded remarkable results. Among the 30 patients who received the combination therapy, the overall response rate was 73.3%, a 30% improvement over PD-1 monotherapy. After more than four years of follow-up, 65% of patients achieved progression-free survival, and 90% were still alive. Four patients reached complete remission, while 11 others underwent surgery, with 10 showing complete pathological remission.

In addition to the notable clinical outcomes, genomic and immunological analysis revealed that high expression of the TAPBP protein was associated with better treatment results. This discovery opens new avenues for the development of biomarkers to predict treatment response and for personalized treatment plans in the future.

Following the publication of the study, it attracted significant attention from the international medical community. Experts from Memorial Sloan Kettering Cancer Center in the U.S. wrote a commentary in the *Med* journal, highly praising the innovative therapy. They noted that the combination of COX inhibitors with PD-1 treatment not only increased the complete remission rate but also reduced immune suppression signals in the tumor microenvironment, enhancing the effectiveness of PD-1 therapy, with manageable side effects.

This research offers new hope for dMMR metastatic colorectal cancer patients worldwide, and further large-scale clinical trials are expected to confirm its efficacy. The combination of COX inhibitors with PD-1 immunotherapy could become a safe and effective treatment option for dMMR metastatic colorectal cancer patients, providing hope for long-term survival.

**Breaking News!  China’s Cancer Drug Outperforms Global PD-1 Inhibitor!**

#AK112 #CancerDrug #PD-1 #PD1Inhibitor #CancerTreatment #BispecificAntibody #NSCLC

China’s pharmaceutical industry has reached a historic milestone! Remember AK112 (Ivonescimab), which took center stage during this year’s ASCO conference, attracting global attention for its groundbreaking potential? The long wait is finally over, and the results are in!

In May, Akeso Biopharma, a leading Chinese pharmaceutical company, announced that its independently developed bispecific antibody drug AK112 achieved a major milestone in clinical trials. AK112 demonstrated superior efficacy to the globally renowned PD-1 inhibitor Keytruda (K Drug) in treating PD-L1-positive non-small cell lung cancer (NSCLC), marking a revolutionary breakthrough for China’s innovative cancer treatments.

**Clinical Data that Surprised the World**

During the World Conference on Lung Cancer 2024, Professor Zhou Caicun, one of China’s top lung cancer experts, revealed the results of the HARMONi-2 study, which had the entire audience applauding. The data exceeded expectations, demonstrating that AK112 is not just on par with but superior to international “superstar” cancer drugs in several key areas.

– **Progression-Free Survival (PFS):** AK112 improved PFS by an astonishing 91.4% compared to Keytruda, reaching 11.14 months versus 5.82 months.

– **Risk Reduction:** AK112 reduced the risk of disease progression or death by 49%.

– **Objective Response Rate (ORR):** AK112 outperformed Keytruda with a response rate of 50.0% compared to 38.5%.

– **Disease Control Rate (DCR):** AK112 maintained a significant advantage, achieving 89.9% versus 70.5%.

While AK112 showed slightly higher Grade 3 side effects due to its VEGF inhibition, its overall performance remains remarkable. Although overall survival (OS) data is still maturing, AK112’s impressive PFS results suggest that its survival benefits will likely be just as extraordinary.

**The Power of Bispecific Antibodies**

AK112 is part of a new class of cancer drugs called bispecific antibodies, capable of targeting two different antigens at once. In this case, AK112 targets both PD-1 and VEGF, two well-known lung cancer markers. This dual-target approach offers patients better therapeutic options and increased convenience, potentially replacing the traditional combination of PD-1 inhibitors with anti-angiogenic drugs like Avastin.

This breakthrough has made AK112 the first and only bispecific antibody drug to outperform Keytruda in head-to-head clinical trials, solidifying its place as a future game-changer in cancer treatment.

**A Milestone for China’s Pharma Industry**

In May 2024, AK112 received regulatory approval from China’s National Medical Products Administration (NMPA) for treating EGFR-mutated, locally advanced, or metastatic NSCLC, becoming the world’s first approved PD-1/VEGF bispecific antibody.

This marks a monumental achievement for China’s pharmaceutical innovation. AK112’s success demonstrates that Chinese researchers and drug developers, in just two decades, have achieved what took developed nations over a century. China’s presence at top-tier global cancer conferences like ASCO and ESMO has never been stronger, with clinical data that leaves the world in awe.

China’s pharmaceutical industry may have started late, but its rapid progress is a testament to the ingenuity and hard work of its researchers. Once relying on generics, China is now a leader in pharmaceutical innovation, offering cutting-edge treatments to patients around the globe. The future of cancer treatment is here, and it’s painted in the bold color of “China Red.”
