SKB264 is a new experimental drug being tested to see if it can help treat certain types of solid tumors. In this study, researchers are looking at how well SKB264 works when used together with another medication. The goal is to find out if this combination can help shrink tumors or stop them from growing, and to see if it is safe for patients to use.

Pembrolizumab is a medication that helps the body’s immune system fight cancer. It works by blocking a specific protein that cancer cells use to hide from the immune system. By blocking this protein, pembrolizumab helps the immune system recognize and attack cancer cells. In this study, it is being used in combination with SKB264 to see if the two drugs together can be more effective in treating certain solid tumors.

Cervical cancer – Cervical cancer is a type of cancer that occurs in the cells of the cervix, which is the lower part of the uterus connecting to the vagina. It typically begins with precancerous changes in the cervical cells, often caused by persistent infection with certain types of human papillomavirus (HPV). As the disease progresses, these abnormal cells can develop into cancerous cells and invade deeper tissues of the cervix and surrounding areas. In advanced stages, the cancer may spread to other parts of the body, including the bladder, rectum, and distant organs. The progression from precancerous changes to invasive cancer can take several years, allowing for potential early detection through screening.

Urothelial carcinoma – Urothelial carcinoma, also known as transitional cell carcinoma, is the most common type of bladder cancer. It originates in the urothelial cells that line the inside of the bladder and can also occur in other parts of the urinary tract, such as the ureters and renal pelvis. The disease often begins as superficial tumors that affect only the inner lining of the bladder. Over time, these tumors can grow deeper into the bladder wall and potentially spread to nearby lymph nodes and other organs. The progression of the disease can vary, with some tumors remaining non-invasive while others become more aggressive.

Ovarian cancer – Ovarian cancer is a type of cancer that begins in the ovaries, which are the female reproductive glands responsible for producing eggs. It often starts in the outer layer of the ovaries and can spread to other parts of the pelvis and abdomen. The disease is known for its subtle symptoms in the early stages, which can lead to delayed diagnosis. As ovarian cancer progresses, it can invade nearby tissues and organs, and eventually spread to distant parts of the body. The progression can be rapid or slow, depending on the type and grade of the cancer cells.

Prostate cancer – Prostate cancer is a common cancer that occurs in the prostate gland, which is a small gland in men that produces seminal fluid. It often begins as small clusters of cancerous cells within the prostate and can grow slowly over many years. In some cases, the cancer may remain confined to the prostate, while in others, it can grow more aggressively and spread to nearby tissues and bones. The progression of prostate cancer can vary widely, with some forms being slow-growing and others more aggressive. Early stages may not cause noticeable symptoms, but as the disease advances, it can lead to urinary and other systemic symptoms.
