What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests LNK01002, a drug that blocks proteins needed for cancer cell growth, in patients with certain blood cancers. It aims to find the safest dose and see how well the drug works.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but you cannot have received certain cancer treatments, radiotherapy, or specific herbal medicines shortly before starting the study. It's best to discuss your current medications with the trial team.

How does the drug LNK01002 work differently from other treatments?

LNK01002 may involve targeting the dual leucine zipper kinase (DLK), which plays a role in neuronal responses to injury and disease, potentially offering a novel approach by influencing pathways involved in neuron protection and regeneration. ^{1 2 3 4 5}

What data supports the effectiveness of the drug LNK01002?

The research suggests that LNK, a component related to LNK01002, plays a role in melanoma by regulating cell growth and survival, and its manipulation could enhance the effectiveness of interferon treatment. This indicates potential therapeutic benefits of targeting LNK in cancer treatment. ^{6 7 8 9 10}
