Pyrotinib versus placebo in combination with trastuzumab and docetaxel as first line treatment in patients with HER2 positive metastatic breast cancer (PHILA): randomised, double blind, multicentre, phase 3 trial

Published date:

Pyrotinib, trastuzumab, and docetaxel showed superiority by significantly improving progression-free survival compared with placebo, trastuzumab, and docetaxel in patients with untreated HER2 positive metastatic breast cancer.

Neoadjuvant pyrotinib, trastuzumab, and docetaxel for HER2-positive breast cancer (PHEDRA): a double-blind, randomized phase 3 trial

Published date:
12/27/2022
Excerpt:
The tpCR rate was 41.0% (95% CI 34.0 to 48.4) in the pyrotinib group compared with 22.0% (95% CI 16.6 to 28.7) in the placebo group (difference, 19.0% [95% CI 9.5 to 28.4]; one-sided P < 0.0001). The objective response rate per investigator was 91.6% (95% CI 86.6 to 94.8) in the pyrotinib group and 81.9% (95% CI 75.6 to 86.9) in the placebo group after the neoadjuvant treatment, resulting in an increase of 9.7% (95% CI 2.7 to 16.6)....Neoadjuvant pyrotinib, trastuzumab, and docetaxel significantly improved the tpCR rate compared with placebo, trastuzumab, and docetaxel, with manageable toxicity, providing a new option for HER2-positive early or locally advanced breast cancer.

LBA19 - Pyrotinib or placebo in combination with trastuzumab and docetaxel for HER2-positive metastatic breast cancer (PHILA): A randomized phase III trial

Published date:
09/05/2022
Excerpt:
Median follow-up was 15.8 mo and 14.9 mo, respectively. PFS per INV of PyroHT was significantly longer than HT (median, 24.3 mo [95% CI 19.1-33.0] vs 10.4 mo [95% CI 9.3-12.3]; HR, 0.41 [95% CI 0.32-0.53]; P < 0.0001; subgroup results are in Table 1), which was consistent with PFS per IRC (median, 33.0 vs 10.4 mo; HR, 0.35 [95% CI 0.27-0.46]). PyroHT significantly prolonged PFS over HT in pts with HER2-positive mBC. The safety is manageable. To our knowledge, this is the second phase 3 trial to demonstrate PFS benefit from dual HER2 inhibition in 1L treatment of HER2-positive mBC.

In total, 175 patients were included. The tpCR rate was 68.6% (95% CI, 60.7-75.8%), while the objective response rate was 89.1%.

We retrospectively evaluated medical records for all patients with HER2-positive metastatic breast cancer who received PyroH plus chemotherapy...PyroH demonstrated a longer PFS than HP when taxane was not utilized (median PFS: 10.12 vs. 8.15 months, p=0.017). In patients with brain metastases receiving first-line treatment, PyroH showed a potential advantage over the HP group...In real-world setting, although HP showed unshakable position when combined with taxane in first-line treatment, PyroH presented comparable effectiveness in post second-line treatment and patients with brain metastasis and even better efficacy in patients without combination of taxane.

Eligible patients (pts) aged 18–70 years with invasive carcinoma, cT2-3N0-3M0 stage, HER2-positive breast cancer were included...Pts in the treatment group received 6 cycles of pyrotinib 400mg + trastuzumab 6mg/kg (LD 8mg/kg) + docetaxel 75mg/m2 + carboplatin (AUC = 6mg/ml·min) (TCbH+Py) treatment...In this study TCbH+Py neoadjuvant therapy significantly improved the tpCR rate of HER2+ breast cancer pts for about twice higher than TCbH with a manageable safety.

Pyrotinib or Lapatinib Combined With Capecitabine in HER2-Positive Metastatic Breast Cancer With Prior Taxanes, Anthracyclines, and/or Trastuzumab: A Randomized, Phase II Study

Excerpt:
Chinese patients with HER2-positive relapsed or metastatic breast cancer previously treated with taxanes, anthracyclines, and/or trastuzumab were assigned (1:1) to receive 400 mg pyrotinib or lapatinib 1,250 mg orally once per day for 21-day cycles in combination with capecitabine (1,000 mg/m2 orally twice per day on days 1 to 14). The overall response rate was 78.5% (95% CI, 68.5% to 88.5%) with pyrotinib and 57.1% (95% CI, 44.9% to 69.4%) with lapatinib (treatment difference, 21.3%; 95% CI, 4.0% to 38.7%; P = .01).

HER2-positive metastatic breast cancer with brain metastases responds favorably to pyrotinib and trastuzumab-based treatment: A case report and literature review

Published date:
01/19/2023
Excerpt:
We herein reported a case of a female patient who was initially diagnosed with HER2-positive metastatic breast cancer with brain metastases, receiving pyrotinib and trastuzumab-based systematic therapy after palliative craniocerebral radiotherapy as the first-line systematic therapy....The patient continued receiving trastuzumab and pyrotinib for HER2-targeted therapy. She had achieved more than 26 months of progression-free survival and the disease was stable during the evaluation in April 2022.

Title:

The successful application of pyrotinib in the treatment of primary trastuzumab-resistant HER-2-positive breast cancer with bilateral axillary lymph node metastasis: a case report

Excerpt:
...a 47-year-old woman diagnosed with HER-2 positive breast cancer with regional lymph nodes metastasis...The patient received trastuzumab-based treatment, but this only afforded a progression-free survival of 5 months, owing to primary trastuzumab resistance. She was then successfully treated with pyrotinib, and the outcome was close to clinical complete response (CCR) with a progression-free survival of over 27 months thus far. This case report may help inform clinicians in the diagnosis of breast cancer with CAM and offer the treatment options in HER-2-positive metastasis breast cancer with primary trastuzumab resistance.
