In addition to the uniqueness <strong>of</strong> the anti-cancer mechanism, the number <strong>of</strong> approved<br />
<strong>in</strong>dications is also one <strong>of</strong> the reasons why PD-1 / PD-L1 antibodies are known as<br />
“disruptive therapies.” Up to now, the above five drugs have been approved for 11<br />
<strong>in</strong>dications, <strong>in</strong>clud<strong>in</strong>g melanoma, non-small cell lung cancer, renal cell carc<strong>in</strong>oma,<br />
classic Hodgk<strong>in</strong> lymphoma, head and neck cancer, bladder cancer (urothelial<br />
carc<strong>in</strong>oma) , colorectal cancer, gastric carc<strong>in</strong>oma, liver cancer, Merkel cell carc<strong>in</strong>oma,<br />
and solid tumors carry<strong>in</strong>g microsatellite <strong>in</strong>stability (MSI-H) or mismatch repair<br />
defects (dMMR).<br />
In addition to the PD-1 / PD-L1 antibody, another immunotherapy called CAR-T also<br />
received significant positive results this year. On August 30, the US FDA formally<br />
approved Novartis’s CAR-T therapy Kymriah for more than a month <strong>in</strong> advance for<br />
the treatment <strong>of</strong> relapsed or refractory (r/r) children and young adults with B-cell<br />
acute lymphoblastic leukemia. This is the first CAR-T therapy approved <strong>in</strong> human<br />
history.
