Summary

This trial is testing a new drug (hSTC810) combined with an existing chemotherapy drug (paclitaxel) in patients whose lung cancer has returned or did not respond to previous treatments. The goal is to determine if this combination is safe and effective. Paclitaxel is a well-known chemotherapy drug used to treat lung cancer and has been used in various combinations to improve treatment outcomes and survival times.

Who is the study for?
This trial is for adults over 18 with small cell lung cancer that has come back or didn't respond to platinum-based chemo. They should have a life expectancy of at least 3 months, be able to understand the study and agree to use contraception. They must have at least one tumor that can be measured and be in fairly good health (ECOG PS of 0 or 1).
What is being tested?
The trial is testing two different doses of hSTC810 combined with Paclitaxel in patients whose extensive stage small cell lung cancer has relapsed or hasn't responded after initial treatment. The goal is to see how safe this combination is and how well it works.
What are the potential side effects?
Possible side effects from hSTC810 and Paclitaxel may include allergic reactions, nerve damage causing pain or numbness, muscle aches, hair loss, nausea, vomiting, diarrhea, low blood counts leading to increased infection risk or bleeding problems.

Other Research
Common treatments for Small Cell Lung Cancer (SCLC) include chemotherapy and immunotherapy. Chemotherapy agents like Paclitaxel stabilize microtubules, preventing cell division and leading to cancer cell death. Immunotherapy, such as anti-PD-1 or anti-PD-L1 therapies, boosts the immune system's ability to recognize and destroy cancer cells. These treatments are vital for SCLC patients due to the aggressive nature of the disease, necessitating effective systemic therapies to improve survival and quality of life.
