About this study

Official title: A Prospective, Open-label Study to Evaluate Injectable Albumin-bound Paclitaxel Versus Docetaxel for the Neoadjuvant Treatment of Breast Cancer

Due to the unique advantages of albumin-bound paclitaxel, several studies in China and abroad have tried to use albumin-bound paclitaxel for neoadjuvant treatment of breast cancer up to now. However, comparative studies between paclitaxel and docetaxel are still rare, In this study, a prospective, randomized, open-label, multi-center clinical study was conducted to analyse the efficacy and safety of albumin-bound paclitaxel and docetaxel in the neoadjuvant treatment of breast cancer, and to further analyse the efficacy and safety of albumin paclitaxel in combination with chemotherapy for postoperative breast cancer in different subtypes of breast cancer patients, in order to obtain more realistic data and provide new treatment options for breast cancer patients.

Read the detailed description

Neoadjuvant chemotherapy refers to systemic chemotherapy as the first step for treating breast cancer patients before planned local treatment like surgery for those without distant metastasis. It is reported that preoperative neoadjuvant chemotherapy can facilitate breast conservation, render inoperable tumors operable and provide important prognostic information at an individual patient level based on response to therapy.

Previous studies have confirmed that the efficacy of albumin-bound paclitaxel in neoadjuvant therapy and was well tolerated when combined with sequential chemotherapy with anthracyclines .

The GBG69 study was the first to compare the efficacy and safety of nab-paclitaxel (nab-P) and solvent-based paclitaxel in the neoadjuvant treatment of breast cancer. The results showed that the pCR rate in the nab-P group was significantly higher than that in the solvent paclitaxel group (38% vs 29% p<0.001). Long-term follow-up results showed that after 4 years, iDFS was also significantly improved in nab-P-treated patients compared with solvent paclitaxel (84.0% vs 76.3%; HR, 0.66; 95% CI, 0.51-0.86; P = 0.0023).

Another phase II study compared docetaxel and albumin paclitaxel in neoadjuvant chemotherapy for HER2-negative early-stage breast cancer. The results showed a slightly higher pCR rate in the nab-P group (docetaxel: 12%; nab-P: 17%). In the Ki67>20% subgroup, the pCR rates were 16% (docetaxel) vs 24% (nab-P) respectively. demonstrating that albumin-bound paclitaxel (nab-P) appears to demonstrate greater efficacy in breast cancer compared to docetaxel.

However, comparative studies between paclitaxel and docetaxel are still rare, In this study, a prospective, randomized, open-label, multi-center clinical study was conducted to analyse the efficacy and safety of albumin-bound paclitaxel and docetaxel in the neoadjuvant treatment of breast cancer, and to further analyse the efficacy and safety of albumin paclitaxel in combination with chemotherapy for postoperative breast cancer in different subtypes of breast cancer patients, in order to obtain more realistic data and provide new treatment options for breast cancer patients.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Yiding CHEN (13605719519, ydchen@zju.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

pCR(pathological complete response) (time frame: 1year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05420454, which also lists 5 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Jul 2022.
