It is primarily intended for dynamic monitoring of patients with malignant tumors to assist in assessing disease progression or treatment efficacy. It shall not be used as a basis for early diagnosis or definitive diagnosis of malignant tumors, nor for cancer screening in the general population.
Kadmon Reports Positive Results for Oral ROCK2 Inhibitor KD025
Recently, Kadmon Holdings announced the latest data from its pivotal ROCKstar clinical trial evaluating KD025, an oral selective Rho-associated coiled-coil containing protein kinase 2 (ROCK2) inhibitor, for the treatment of chronic graft-versus-host disease (cGVHD). The results showed that an interim analysis conducted two months after completion of patient enrollment (October 2019) had met the objective response rate (ORR) endpoint. Data indicated that the ORRs were 64% and 67% in the groups receiving KD025 200 mg once daily and 200 mg twice daily, respectively, with both results being statistically and clinically significant.
Hengrui Medicine’s Oral A2AR Antagonist SHR5126 Approved for Clinical Trials
On February 24, Hengrui Medicine announced that SHR5126 tablets had received approval for clinical trials, with the intended use being the treatment of patients with solid tumors; specific indications are to be determined through clinical trials.

“Cancer Cell”: Circular RNAs Restrict Metastasis of Skin Cancer
Recently, a new study has found that a mysterious genetic material can inhibit the spread of skin cancer cells, but this substance is often lost as they mature. This new research was recently published in "Cancer Cell". Typically, DNA is converted into RNA, which is then translated into proteins with cellular functions. While most RNAs are linear molecules, some form circles when their ends loop and attach to each other. This new study shows that when the interaction between CDR1as and the RNA-binding protein IGF2BP3 is disrupted, melanoma metastasis begins.
*Nature*: Novel Immune Cells Aid Cancer Immunotherapy
Recently, a research team from MSK discovered a group of immune cells known as innate lymphoid cells (ILCs). These cells are present in many different tissues and appear to exert mild anti-tumor effects under normal, quiescent conditions. The researchers demonstrated that pharmacological activation of ILCs can mobilize T cells to reduce the volume of pancreatic cancer tumors. Vinod Balachandran, a surgical scientist affiliated with the Pancreatic Cancer Research Center and an author of the study, stated, “We believe this represents an important discovery for both pancreatic cancer research and cancer immunotherapy as a whole. We are learning how to harness multiple components of the immune system to combat cancer. We think this signals the imminent emergence of new immunotherapies.” The relevant findings were published in the recent issue of Nature.
