APL-1702 is a pioneering cold light photodynamic drug-device combination product, used as a non-surgical therapy for treating cervical HSIL. This study is a prospective, randomized, double-blinded, placebo-controlled multicenter Phase III global clinical study designed to evaluate the efficacy and safety of APL-1702 for the treatment of cervical HSIL. Primary endpoint of the study is the proportion of responders at 6 months after the initial treatment. The study is led by Dr. Jinghe Lang, an academician at Peking Union Medical College Hospital, Chinese Academy of Medical Sciences. Response is defined as the conversion of cervical epithelial tissue pathology to normal or the conversion to low-grade squamous intraepithelial lesion (LSIL) while achieving baseline HPV clearance.

According to the study results, between November 2020 and July 2022, a total of 402 eligible patients from various countries including China, Germany, the Netherlands et al. were randomized and enrolled in this study. The response rate in the APL-1702 treatment group showed a statistically significant improvement of 89.4% (41.1% vs. 21.7%, p = 0.0001) compared to that in the placebo control group, indicating a remarkable therapeutic effect. Additionally, APL-1702 showed an improved clearance rate of high-risk HPV16 and/or HPV18, with a 103.9% increase in the APL-1702 treatment group compared to the control group (31.4% vs. 15.4%)[1]. The incidence of treatment-emergent adverse events (TEAEs) was comparable between the treatment group and the control group, with the majority being mild and self-healing without requiring intervention. The occurrence rates of treatment-related adverse events (TRAEs) and serious adverse events (SAEs) were both low in both groups[2].

According to the "Global Cancer Statistics 2020" report, there were 604,127 new cases of cervical cancer in women worldwide in 2020, with 341,831 deaths, ranking it as the fourth most common cancer among women. Cervical cancer incidence ranks second among malignant tumors in Chinese women. According to the "National Cancer Report 2024" released by the National Cancer Center, there were 150,700 new cases of cervical cancer in China in 2022, with 55,700 deaths from cervical cancer.

The main cause of cervical cancer is persistent infection with human papillomavirus (HPV), which leads to precancerous lesions of the cervix. Approximately 25% of individuals with HSIL may progress to invasive cervical cancer within 10 years[3]. According to Frost Sullivan analysis, it is projected that by 2030, the number of HSIL patients worldwide and in China will reach 16.6 million and 2.2 million, respectively. With the increasing popularity of dual-cancer screening and cervical cytology tests, more and more patients with cervical precancerous lesions are being detected at early stages before cancer develops, and it is expected that the number of patients will continue to increase.

Women with cervical precancerous lesions have unmet clinical needs for non-surgical therapies. Currently, invasive procedures such as loop electrosurgical excision procedure (LEEP) and cold knife conization remain the primary treatment options for high-grade cervical lesions. However, these surgical treatments are associated with adverse reactions including bleeding, infection, and cervical structural damage, which may lead to complications such as preterm birth and miscarriage. Furthermore, cervical precancerous lesions require long-term monitoring and management because even after surgical treatment, there is a risk of persistent disease or recurrence, with a higher risk of developing cervical cancer compared to the general population (5 times higher risk of invasive cancer within 10 years). Therefore, post-operative follow-up for at least 25 years is necessary. Importantly, if cervical precancerous lesions recur, subsequent surgical interventions become more challenging and carry higher risks, potentially resulting in total hysterectomy. Thus, early surgical intervention increases the difficulty of long-term management. Non-surgical therapies that preserve the intact cervix and avoid or delay cervical trauma are of significant importance for the long-term management of patients with cervical precancerous lesions.

Professor Chen Fei, Chief Physician of the Department of Obstetrics and Gynecology at Peking Union Medical College Hospital, expressed her delight with the research findings, stating, "I am extremely pleased with the results of this study. Treating HSIL serves as the final barrier against cervical cancer. Previous international studies on HSIL have not been successful, but this study, utilizing a multicenter trial design and strict definition of efficacy endpoints, has achieved positive results, which is no easy feat. As a clinician, I have encountered many HSIL patients who desire to preserve their intact cervix while receiving treatment. The emergence of APL-1702 will fulfill the wishes of these patients, allowing them to avoid or delay cervical trauma to the maximum extent possible."

Professor Qiao Youlin, a member of the WHO Global Expert Group for Cervical Cancer Elimination and a professor at the School of Population Medicine and Public Health at the Chinese Academy of Medical Sciences/Peking Union Medical College, believes that in addition to vaccination and screening, treatment of cervical precancerous lesions is a crucial component of secondary prevention for cervical cancer. However, progress in the field of medication for cervical precancerous lesions has been relatively slow, with high barriers to overcome, and there are currently no approved treatment drugs worldwide. "It is gratifying to see the emergence of innovative products like APL-1702, which simultaneously possess clinical value in addressing the treatment gap, public health value in cervical cancer prevention and control, and social value in promoting fertility-friendly options. This breakthrough will safeguard women’s health and make a positive contribution to the acceleration of the 2030 global and Chinese action plans for cervical cancer elimination".

Dr. Linda Wu, Chief Development Officer of Asieris Pharmaceuticals, said, "We are extremely proud of the results from the international multicenter Phase III clinical study of APL-1702. The study not only demonstrates remarkable efficacy but also exhibits a favorable safety profile, offering a new powerful artillery for the national cervical cancer prevention and control system. We express our gratitude to all the patients, physicians, and researchers who participated in this study, as their support and dedication have been invaluable. We are actively preparing the new drug application for APL-1702 and plan to submit it in the second quarter of this year. Additionally, we are making significant progress in product development overseas, aiming to bring this innovative treatment to more patients as soon as possible."

The new drug application (NDA) of tunlametinib was previously granted priority review by the Center for Drug Evaluation (CDE) of the NMPA. The approval was based on the results of a multicenter, single-arm, phase II, pivotal registrational study which conducted in 100 patients in China (NCT 05217303). Clinical efficacy data of tunlametinib in China, as assessed by independent radiological review committee (IRRC) per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1, include an overall response rate (ORR) of 35.8%, median progression free survival (PFS) of 4.2 months, and disease control rate (DCR) of 72.6%. Subgroup analysis showed that in patients who had previously received immunotherapy, the ORR was 40.6%. The most common treatment-related skin event was rash (53%), followed by dermatitis acneiform (24%). The most common grade ≥3 TRAE in this study was blood creatine phosphokinase increased (38.0%), which was mostly asymptomatic and manageable with dose modification [1].

"We are excited and proud of this major milestone for KeChow. Tunlametinib, approved in China, is the first internally designed and developed molecule by KeChow team ." said Dr. Hongqi Tian, Founder, Chief Executive Officer and Chairman of KeChow. "The approval of tunlametinib is an important milestone to provide new treatment option for Chinese patients with NRAS-mutated advanced melanoma who previously received PD-1/PD-L1. We would like to express our sincere gratitude to the clinicians and patients who participated in our trials, and we thank the health authorities for their strong support. We are committed to making tunlametinib available in China as soon as possible to serve this patient population."

"We own the worldwide rights to tunlametinib. KeChow has a comprehensive clinical development plan to evaluate tunlametinib as a monotherapy and in combination with other standard of care therapies to treat multiple cancers including melanoma, neurofibromatosis type 1–related plexiform neurofibromas, colorectal cancer, and non-small cell lung cancer in China," said Dr. Hongqi Tian. "We look forward to expanding the product potential of tunlametinib through establishing partnerships on a worldwide basis."

Melanoma is one of the most common cutaneous cancers. There are an estimated 20,000 newly diagnosed melanoma patients in China each year [2]. NRAS mutations accounted for 10.4~12.6% of melanoma patients in China [3], and 15-25% globally [4-7]. NRAS-mutated melanoma is more aggressive and associated with poorer outcomes [8-11]. There were no approved targeted therapies for patients with NRAS-mutant melanoma. Tunlametinib is the first small molecule drug approved for this indication.

About tunlametinib

Tunlametinib is a small molecule inhibitor of Mitogen-activated protein kinase kinase (MEK) discovered and developed by KeChow. Tunlametinib targets the Mitogen-activated protein kinase (MAPK)/extracellular regulated protein kinases (ERK) signaling pathway (also known as RAS/RAF/MEK/ERK signaling pathway) by inhibiting the activity of MEK kinase, blocking downstream signaling pathways, inhibiting the growth and proliferation of tumor cell. MAPK/ERK signaling pathway plays a critical role in cancer cell proliferation and apoptosis. Aberrant activation of this signaling pathway has been implicated in more than one-third of all malignancies. Compared to other approved MEK inhibitors, tunlametinib demonstrated stronger target inhibition and improved pharmacokinetic properties.

The Company presented initial data from Part A of the DeFianCe study (NCT05480306), a Phase 2 study evaluating DKN-01 in combination with standard of care (SOC) bevacizumab and chemotherapy in second-line (2L) patients with advanced microsatellite stable (MSS) CRC patients at the 2024 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Gastrointestinal Cancers Symposium, held in San Francisco on January 18-20, 2024 and during the Company’s conference call on January 23, 2024.
Key Findings:
As of the December 6, 2023 data cutoff, across all patients enrolled (n=33):
Overall response rate (ORR) among response-evaluable patients (n=27) was 30% and disease control rate (DCR) was 93%, including 8 partial responses (PR) and 17 patients with a best response of stable disease (SD)
Median progression-free survival (PFS) was 6.3 months
9 patients remained on therapy and were beyond 8.5 months
Enhanced activity in patients with left-sided tumors (n=25), a group that has more frequent activation of the Wnt pathway modulated by DKK1
33% ORR and 100% DCR in response-evaluable population (7 PRs, 14 SDs)
Preliminary median PFS of 8.6 months (9 patients continuing therapy within subgroup)
Compelling ORR, DCR and PFS in patients with rectal/rectosigmoid carcinomas (n=15), a population with increasing incidence among young people and shown to have the highest DKK1 levels:
46% ORR and 100% DCR in response-evaluable population (6 PRs, 7 SDs)
Preliminary median PFS of 9.4 months (6 patients continuing therapy within subgroup)
Higher baseline plasma DKK1 levels correlated with improved responses
DKN-01 plus bevacizumab and chemotherapy was well-tolerated, with a majority of DKN-01 related events being low grade (Grade 1/2)
The Company expects the 130 patient randomized controlled Part B to complete enrollment in mid-2024. As of March 15, 2024, 80 patients have enrolled in Part B.

Announced completion of enrollment in the randomized controlled Part C of the DisTinGuish study evaluating DKN-01 in combination with tislelizumab, BeiGene’s anti-PD-1 antibody, and chemotherapy in patients with advanced gastroesophageal junction and gastric cancer.

About ONS-5010 / LYTENAVA (bevacizumab-vikg, bevacizumab gamma)

ONS-5010/LYTENAVA is an investigational ophthalmic formulation of bevacizumab under development as an intravitreal injection for the treatment of wet AMD and other retinal diseases. Because no FDA or European Commission approved ophthalmic formulations of bevacizumab are available currently, clinicians wishing to treat retinal patients with bevacizumab have had to use repackaged IV bevacizumab provided by compounding pharmacies—products that have known risks of contamination and inconsistent potency and availability. If approved, ONS-5010/LYTENAVA would provide an approved option for physicians to treat wet AMD.

Bevacizumab-vikg/bevacizumab gamma is a recombinant humanized monoclonal antibody (mAb) that selectively binds with high affinity to all isoforms of human vascular endothelial growth factor (VEGF) and neutralizes VEGF’s biologic activity through a steric blocking of the binding of VEGF to its receptors Flt-1 (VEGFR-1) and KDR (VEGFR-2) on the surface of endothelial cells. Following intravitreal injection, the binding of bevacizumab-vikg to VEGF prevents the interaction of VEGF with its receptors on the surface of endothelial cells, reducing endothelial cell proliferation, vascular leakage, and new blood vessel formation in the retina.
