What is the purpose of this trial?

This trial tests whether a combination of two chemotherapy drugs, docetaxel and carboplatin, can effectively treat triple-negative breast cancer. This type of breast cancer lacks certain common receptors, making it harder to treat. Suitable candidates for the trial have been diagnosed with invasive breast cancer that is both estrogen receptor-negative and HER2-negative. Participants should have a primary breast tumor of at least 2 cm and must not have received any systemic therapy for breast cancer in the last five years. The trial aims to assess how well this drug combination shrinks tumors and improves patient outcomes. As a Phase 2 trial, the research focuses on measuring the treatment's effectiveness in an initial, smaller group of people, offering participants a chance to contribute to significant advancements in cancer treatment.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. However, if you are currently receiving any investigational agents, you would not be eligible to participate.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that combining docetaxel and carboplatin is generally well-tolerated by patients. One study found no major safety concerns for early breast cancer patients in the Asia-Pacific region using this drug combination. Another study on patients with advanced cancers found the treatment both safe and effective.

These drugs are often used to treat various types of cancer, indicating confidence in their safety. While side effects can occur, research indicates that serious side effects are uncommon with this treatment. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising for breast cancer?

Researchers are excited about using carboplatin and docetaxel together for treating breast cancer because this combination may enhance the effectiveness of chemotherapy. Unlike standard treatments that often focus solely on traditional drugs like anthracyclines or taxanes, this approach combines a platinum-based drug (carboplatin) with a taxane (docetaxel), potentially overcoming resistance to other therapies. The synergy between these two drugs could lead to better tumor reduction and improved outcomes for patients, offering new hope for those who have limited responses to existing treatments.

What evidence suggests that this treatment might be an effective treatment for triple negative breast cancer?

Studies have shown that using the drugs docetaxel and carboplatin together can effectively treat breast cancer. Earlier research reported a 60% overall response rate with this combination, indicating that many patients experienced a reduction or disappearance of their cancer. Specifically, 6% of patients saw their cancer completely disappear, while 54% saw it shrink. Another study found that this treatment increased the rate of complete cancer disappearance compared to other drug combinations. These findings suggest that using docetaxel and carboplatin together might be a promising option for treating triple-negative breast cancer. Participants in this trial will receive this combination treatment to further evaluate its effectiveness. ^{3 6 7 8 9}

Are You a Good Fit for This Trial?

This trial is for adults with invasive triple negative breast cancer, where the tumor is at least 2 cm. They must have normal organ and bone marrow function, not be pregnant or breastfeeding, agree to use contraception if of childbearing potential, and have no severe illnesses that could interfere with the study. Prior systemic therapy for breast cancer within 5 years disqualifies them.

Inclusion Criteria

My breast cancer is in multiple spots, all are estrogen and HER2 negative.

I have a breast lump at least 2cm big, confirmed by imaging.

My blood tests show normal organ function and healthy blood cell counts.

Exclusion Criteria

I do not have any severe illnesses or social situations that would stop me from following the study's requirements.

Currently receiving any other investigational agents

I have not had cancer, except for certain skin cancers or cervical pre-cancer, in the last 5 years.

Published Research Related to This Trial

Docetaxel, when combined with cisplatin, shows promising efficacy in treating non-small cell lung cancer, with response rates between 32% to 52% and a median survival of 8 to 12 months based on phase II studies involving various patient populations.

The combination therapy is generally well-tolerated, with neutropenia being the main dose-limiting side effect, while severe neuropathy and nephrotoxicity are rare, indicating a favorable safety profile.

Docetaxel (Taxotere) in combination with platinums in patients with non-small cell lung cancer: trial data and implications for clinical management. Belani, C., Lynch, T.[2018]

The combination of docetaxel and cisplatin is effective for treating stage IIIB/IV non-small cell lung cancer, showing response rates between 32% and 48% and median survival times of 8 to 13 months across four phase II trials.

Docetaxel combined with carboplatin also demonstrated promising results, with a 48% response rate in a small group of 27 patients, indicating that these combinations are well tolerated and may improve outcomes if used earlier in the disease progression.

Docetaxel (Taxotere) in combination with platinum-based regimens in non-small cell lung cancer: results and future developments. Belani, CP.[2018]

The combination of docetaxel and cisplatin showed a response rate of 32% and a median survival of 11.5 months in patients with advanced non-small-cell lung cancer (NSCLC), indicating its efficacy as a treatment option.

When combined with carboplatin, docetaxel demonstrated an improved response rate of 36% and a longer median survival of 13.9 months, suggesting that this combination may have a better safety profile and therapeutic index compared to the cisplatin combination.

Docetaxel shows comparable efficacy to paclitaxel in treating ovarian cancer, with a median progression-free survival of 16 months and a low neurotoxicity rate of 5%, significantly lower than the over 30% seen with paclitaxel.

In a large randomized trial involving 1077 patients, docetaxel combined with carboplatin demonstrated acceptable toxicity and treatment adherence, justifying further analysis of its safety and efficacy compared to the traditional paclitaxel-carboplatin regimen.

In a dose-finding study, the combination of docetaxel and cisplatin showed a promising response rate of 60% in patients with metastatic breast cancer, indicating its potential as an effective first-line treatment option.

Carboplatin, due to its lower toxicity, may also be a viable alternative in combination with taxanes, while vinorelbine combined with docetaxel achieved a response rate of 59% in patients previously treated with anthracyclines.

In a study comparing carboplatin combined with either paclitaxel or docetaxel in four ovarian carcinoma cell lines, both combinations showed a synergistic effect, enhancing the growth inhibitory impact on cancer cells.

The combination of carboplatin with paclitaxel produced a broader range of supra-additive effects across various concentrations compared to the carboplatin-docetaxel combination, suggesting that paclitaxel may be more effective in this context.
