Trial Summary

What is the purpose of this trial?

This trial is testing a new drug called DB-1310 to see if it is safe for patients with advanced solid tumors. It will also check if combining DB-1310 with another drug, trastuzumab, helps fight cancer better.

Do I have to stop taking my current medications for the trial?

The trial protocol does not specify if you must stop taking your current medications. However, you may need to avoid certain drugs that affect the heart's rhythm or those that interact with specific enzymes (CYP3A4). It's best to discuss your current medications with the trial team.

What data supports the effectiveness of the drug DB-1310 for advanced cancer?

The research mentions capecitabine, a component of DB-1310, as an effective treatment for advanced breast cancer, showing response rates of 20-36% in various studies. This suggests potential effectiveness of DB-1310 in treating advanced cancer. ^{1 2 3 4 5}

Treatment Details

Interventions

• DB-1310 (Other)

Trial Overview DB-1310 is being tested in this Phase 1/2a trial to see how safe it is and how well people with advanced solid tumors can handle different doses. The study will gradually increase the dose (dose-escalation) and then give it to more people at the best dose found (dose-expansion).

Findings from Research

The combination of docetaxel and capecitabine was found to be effective in treating anthracycline-resistant metastatic breast cancer, achieving an overall response rate of 46.9% among 32 patients, with a median time to progression of 5.6 months.

The treatment was generally well-tolerated, although common side effects included myelosuppression and hand-foot syndrome, with 84.4% of patients experiencing neutropenia.

[Docetaxel and capecitabine combination chemotherapy for patients with anthracycline-resistant metastatic breast cancer]. Li, SF., Wang, X., Wang, C., et al.[2018]

Oral chemotherapy options like Xeloda (capecitabine) and oral vinorelbine improve access for patients with metastatic breast cancer, especially when hospital visits are challenging due to financial or logistical reasons.

Combination therapies using taxoids and anthracyclines have increased response rates in first-line treatments, but maintenance regimens with less toxic agents can prolong response duration and improve disease-free survival, making outpatient treatment more feasible.
