The trial team concluded that NUC-1031 helps people with solid tumours that have spread to other parts of the body (advanced solid tumours).
68 people took part in this
phase 1 trial. Everyone had NUC-1031 as an
injection into a vein once a week, for 3 weeks. They then had a break of a week. They continued to have NUC-1031 for 3 weeks out of every 4 weeks for as long as the treatment was helping them.
This trial was in 2 parts. In the 1st part, people had different doses of NUC-1031. The first few people had a low dose of NUC-1031. As they didn’t have bad side effects, the next few people had a higher dose. And so on, until the research team found the best dose to give. A total of 47 people joined this part of the trial.
In the 2nd part, everyone had the highest safe dose found during part one. A total of 21 people joined this part of the trial.
Results
Doctors were able to find the highest safe dose of NUC-1031 during the 1st part of the trial. They then gave that dose to everyone that joined the 2nd part.
The trial team looked at how well NUC-1031 worked. To do this, they looked at the results of 49 people. Doctors found that:
- in 5 out of the 49 people, the cancer shrunk by at least a third (partial response). This is around 1 in every 10 people who took part (10%)
- in 33 out of the 49 people, the cancer stayed the same, or shrunk by less than 30% (stable disease). This is almost 7 in every 10 people who took part (70%)
- in 11 out of the 49 people, their cancer grew (progressive disease)
- in 10 out of the 16 people who had cancer that had previously not responded to gemcitabine, the cancer shrank or stayed the same
Side effects
Doctors looked at the moderate and serious side effects that people had. Side effects included:
Conclusion
The trial team concluded that NUC-1031 helps people with advanced solid tumours. They think it is a safe treatment.
Doctors are now looking at how well NUC-1031 works alone and together with other anti cancer drugs for people with pancreatic cancer, ovarian cancer or cancer of the bile duct.
