About
Immune therapies work with the body's immune system to treat a number of cancers. They work with T-cells, a type of white blood cell, to target and attack specific tumors. However, some tumors can become resistant to attack by T-cells over time. They do this by sending "off" signals to T-cells. The researchers are finding ways to switch the T-cells back on.
Before a treatment can be approved for use, clinical studies need to be done. This study will provide more information on ASP1570 in adults with advanced solid tumors. ASP1570 will either be given by itself, or given with another medicine called pembrolizumab, or given with a standard cancer therapy.
The main aims of this study are：
- To check the safety of ASP1570
- To check how well ASP1570 is tolerated
- To find a suitable dose of ASP1570
This study is for adults with advanced solid tumors. Their tumor has either grown outside of the area where it started (locally advanced and unresectable) or it has spread to other parts of the body (metastatic). Their cancer gets worse after standard therapy or they are unable to have standard therapy. The study doctors can give more advice about who can take part.
This study will be in 2 parts.
In Part 1, the most suitable dose of ASP1570 to give to people with advanced solid tumors will be worked out. Different small groups of people with advanced solid tumors will take lower to higher doses of ASP1570. People will either be given ASP1570 by itself, ASP1570 with another medicine called pembrolizumab, or ASP1570 with a standard cancer therapy. The study treatment given depends on the type of cancer people have. There are different doses of ASP1570, with each group staying on the same dose. There is just 1 dose of pembrolizumab. The dose of a standard cancer therapy depends on its label. After taking the lowest dose of ASP1570, the first group will be checked for medical problems. The next group can only take the higher dose of ASP1570 if the first group tolerates the lowest dose . This will continue in the same way for each group.
Each group will take tablets of ASP1570 either once or twice every day in a 21-day cycle. People taking part in Japan will stay in hospital for up to 21 days during the first treatment cycle only. People will continue with more treatment cycles on the same dose unless they can't tolerate the study treatment, their cancer gets worse or the study doctor decides that person should stop treatment. People who also receive treatment with pembrolizumab will be infused with pembrolizumab on the first day of every other cycle of ASP1570 (once every 6 weeks). People who are receiving standard cancer therapy (with ASP1570) will be treated according to its label.
In Part 2, different small groups of people with advanced solid tumors will take the most suitable dose of ASP1570 worked out from Part 1. The dose will not go above the highest dose that people could tolerate from Part 1. Some groups of people will have specific advanced tumors. These include colorectal cancer or non-small cell lung cancer (NSCLC for short). Again, each group will take tablets of ASP1570 once or twice every day in a 21-day or 28-day cycle. People with NSCLC will also receive docetaxel, one of the standard cancer therapies. People with stable colorectal cancer (known as CRC with microsatellite stability, or MSS-CRC) will also receive another standard cancer therapy called TAS-102 with bevacizumab. The standard cancer therapies will be given according to their label. People with solid tumors will also receive pembrolizumab on the first day of every other cycle of ASP1570 (once every 6 weeks). All groups will continue with more treatment cycles with ASP1570 by itself with pembrolizumab, or with one of the standard cancer therapies unless they can't tolerate the study treatment, their cancer gets worse or the study doctor decides that person should stop treatment.
