CHENGDU, China, Sept. 28, 2024 /PRNewswire/ — From September 25th to 29th, the twenty seventh China Medical Oncology Congress and the 2024 CSCO Annual Assembly had been held in Xiamen. Specialists and students within the area of oncology from throughout China gathered collectively to debate the hotspots on the forefront of scientific follow. Sichuan Kelun-Biotech Biopharmaceutical Co., Ltd. (“Kelun-Biotech”, 6990.HK) introduced a number of scientific analysis outcomes and progress of TROP2 ADC sacituzumab tirumotecan (sac-™T, previously SKB264/MK-2870) on the convention.
TNBC
On the afternoon of September 27, Academician Binghe Xu from the Most cancers Hospital of the Chinese language Academy of Medical Sciences gave an oral presentation and paper dialogue on the outcomes of the Section III OptiTROP-Breast01 examine of sacituzumab tirumotecan (sac-™T) in sufferers (pts) with beforehand handled domestically recurrent or metastatic triple-negative breast most cancers (TNBC) within the Progressive Medicine Medical Information Session.
The median PFS assessed by BICR was 6.7 months (95% CI, 5.5 to eight.0) with SKB264 and a couple of.5 months (95% CI, 1.7 to 2.7) with chemotherapy; The sac-™T group had a 68% discount in danger of illness development or loss of life in comparison with the chemotherapy group (HR 0.32; 95% CI, 0.22 to 0.44; P 200, the median PFS was 8.3 months with SKB264 and a couple of.3 months with chemotherapy (HR 0.29; 95% CI, 0.19 to 0.46). The median OS was not reached (95% CI, 11.2 to NE) with SKB264 and 9.4 months (95% CI, 8.5 to 11.7) with chemotherapy. The sac-™T group had a 47% discount in danger of loss of life in comparison with the chemotherapy group (HR 0.53; 95% CI, 0.36 to 0.78; P =0.00005). In comparison with the investigator’s selection of chemotherapy, sac-™T for metastatic TNBC sufferers confirmed statistically and clinically important enhancements in PFS and OS, with a manageable security profile, and could possibly be a brand new and efficient therapeutic possibility for this group of sufferers.
Binghe Xu mentioned, “Breast cancer is a highly prevalent malignant tumor in the world, threatening women’s lives and health, among which, triple-negative breast cancer is also known as ‘the most toxic’ breast cancer due to its poor therapeutic effect. The future direction of advanced triple-negative breast cancer treatment is precise and stratified treatment. Sac-™T can help to meet more treatment needs of patients, and may be expected to become the new standard of second-line treatment for advanced triple-negative breast cancer in the future. For the research and development of ADC, domestic enterprises have gone through the stages of catching up and running parallel to each other, and now they have become an important force in the global ADC innovation technology, and we believe that one day, patients with advanced triple-negative breast cancer can get more effective treatment through ADC innovative drugs.”
NSCLC
On the afternoon of September 28, Prof. Wenfeng Fang from the Affiliated Most cancers Hospital of Solar Yat-sen College orally reported the outcomes of the Section II OptiTROP-Lung01study, a first-line therapy for sufferers with superior non-small-cell lung most cancers (NSCLC) with sac-™T together with KL-A167, an anti-PD-L1 monoclonal antibody, within the session of Medical Information of Progressive Medicine, with a paper dialogue.
Pts with therapy naive superior NSCLC with out actionable genomic alterations had been enrolled to obtain SKB264 5 mg/kg Q3W + KL-A167 1200 mg Q3W (cohort 1A，130 Pts) or SKB264 5 mg/kg Q2W + KL-A167 900 mg Q2W (cohort 1B,133 Pts) in a non-randomized method. After median comply with up of 14.0 mo and 6.9 mo for cohort 1A and 1B, the ORR was 48.6% (18/37, 2 pending affirmation), DCR was 94.6% and median PFS was 15.4 mo (95% CI: 6.7, NE) with 6-mo PFS price of 69.2% for cohort 1A ; the ORR was 77.6% (45/58, 5 pending affirmation), DCR was 100% and median PFS was not reached with 6-mo PFS price of 84.6% for cohort 1B.
Prof. Wenfeng Fang mentioned, “The emergence of ADC drugs is epoch-making. The dual-drug regimen of sac-™T combined with immunotherapy is leading a new direction in the exploration of first-line treatment for advanced NSCLC, with very stunning efficacy observed in the preliminary study data. In the future, the potential for the application of sac-™T in the treatment of NSCLC is worth looking forward to, and sac-™T is expected to provide diversified treatment options and better survival benefits for more patients, both in the driver-negative and EGFR-mutated patient populations.”
CC
On the morning of September 28, Professor Jing Wang from Hunan Most cancers Hospital orally reported the outcomes of Efficacy and Security of sac-™T Plus Pembrolizumab in sufferers with recurrent or metastatic cervical most cancers. Pts with R/M CC who had progressed on or after platinum-doublet chemotherapy and obtained not more than 2 systemic therapies for R/M illness had been enrolled.38 pts had been handled and adopted up for not less than 17 weeks or 2 tumor assessments. The median follow-up was 6.2 mo, The ORR was 57.9% (22/38, 3 unconfirmed), with 3 full responses. Responses had been additionally noticed in pts had been pre-treated with anti-PD-1 based mostly remedy. Median PFS was not reached and 6-mo PFS price was 65.7%.
Professor Jing Wang mentioned, “Cervical cancer highly expresses TROP2, and previous studies have suggested that the overexpression ratio is more than 90%. High TROP2 expression is closely related to the poor prognosis of tumor patients, and it may also be related to the sensitivity of some drug therapies, which makes it a good target to explore. It is believed that with these promising results, more studies will emerge in the field of gynecologic oncology in the future to further validate these findings and bring hope to a wider range of cancer patients.”
EC/OC
On the morning of September 28, Dr. Zhuo Yang from Liaoning Provincial Most cancers Hospital shared the outcomes of security and efficacy of sac-™T in pts with beforehand handled superior endometrial carcinoma (EC) and ovarian most cancers (OC) from a Section 2 Research. Within the endometrial most cancers cohort, 44 EC pts had been enrolled and median follow-up time was 7.2 mo. 52.3% of pts had obtained ‰¥ 2 prior strains of remedy. The ORR was 34.1% (15/44, 12 confirmed) and DCR was 75%. Median PFS was 5.7 mo (95% CI: 3.7, 9.4) with 6-mo PFS price of 47.5%.
40 OC pts had been enrolled and median follow-up time was 28.2 mo. All pts had obtained ‰¥ 2 prior strains of remedy (80% of pts ‰¥ 3 prior strains). 87.5% of pts had been platinum-resistant. The ORR was 40% (16/40, 14 confirmed) and DCR was 75%. mPFS was 6.0 mo (95% CI: 3.9, 7.3); mo was 16.5 mo (95% CI: 10.7, NE). Within the pts with TROP2 IHC H-score > 200 (n=13) or H-score ‰¤ 200 (n=22), the ORR was 61.5% (8/13, 7 confirmed) and 27.3% (6/22, 6 confirmed) respectively. Within the pts with platinum-resistant (n=35), mPFS was 6.0 mo (95% CI: 5.3, 7.3) and mOS was 16.1 mo (95% CI: 10.5, NE).
Prof Danbo Wang mentioned, “Ovarian cancer and endometrial cancer have their own epidemiological characteristics, and the incidence rate of endometrial cancer in developed cities in China is increasing year by year, and it may become the top gynecological malignant tumor in Chinese women in the future. In contrast, ovarian cancer is characterized by insidious onset, high late detection rate and high mortality rate. Exploring new therapeutic strategies to overcome platinum resistance and improve the survival rate of ovarian cancer patients is a key direction for future research. Sac-™T shows great potential in the treatment of advanced endometrial and ovarian cancers. It has not only achieved remarkable results in terms of efficacy, but also well controlled safety. I believe that in the future research and application, it will become a leader in the field of ADC innovative drug development and bring new hope to more gynecological oncology patients.”
