Abstract
The incidence of cancer globally is increasing, predominantly because of an aging population and bringing with it substantial challenges. Cancer vaccines are based on the premise that there are unique features of a cancer or agents causing a cancer which are recognizable by the immune system. Cancer vaccines can be classified as preventive and therapeutic. We searched Trialtrove and identified 2100 clinical trials of cancer vaccine published January 1, 2000 to November 1, 2024, numbers of trials have been explosive growth since 2008: 37% were phase-1, 21%, phase-1/phase-2, 32%, phase-2, 2%, phase-2/phase-3, 5%, phase-3 and 1%, phase-4. Most studies are in the USA (45%). 1% were in infants, 5% in children, and 94% on adults. The most common cancer studied is non-small-cell lung cancer (N=298; 12%) followed by melanoma (N=277; 11%). In conclusion, the research of cancer vaccines is rapidly advancing, particularly in therapeutic cancer vaccines. An increasing number of multicenter clinical trials of cancer vaccines are being initiated globally, and these efforts hold significant promise for bringing hope to patients with cancer.
