Hypothesis

The antibody GT103 targets complement factor H to promote anti-cancer immunity in patients with refractory non-small cell lung cancer.

Conclusion

GT103 was found to be safe and well tolerated, with some patients achieving stable disease.

Supporting Evidence

  • GT103 was well tolerated at all dose levels, including the highest doses.
  • Stable disease was observed in 9 patients, representing a disease control rate of 29%.
  • The median overall survival was 25.7 weeks.

Takeaway

Researchers tested a new antibody called GT103 in lung cancer patients, and while it didn't shrink tumors, it was safe and some patients had stable disease.

Methodology

A phase 1b dose escalation trial was conducted to assess the safety and tolerability of GT103 in patients with refractory non-small cell lung cancer.

Potential Biases

Selection bias may have occurred due to the heavily pretreated patient population.

Limitations

The study had a small sample size and was a single-arm trial without a control group.

Participant Demographics

Median age was 63 years, 61% male, 74% white, and 71% had ECOG performance status 1.

Statistical Information

Confidence Interval

95% CI, 19.1–30.6 for median overall survival
