Anthracyclines
Anthracyclines
Anthracyclines are a class of chemotherapeutic agents derived from the bacterium Streptomyces peucetius.
These potent anti-cancer drugs work by intercalating into DNA and inhibiting topoisomerase II, leading to cell death.
Anthracyclines are commonly used to treat a wide range of cancers, including leukemia, lymphoma, and solid tumors.
However, their use can be limited by the risk of serious side effects, such as cardiotoxicity.
Researchers can leverrage PubCompare.ai to streamline anthracycline research, easily locate protocols, and optimize thier studies through AI-powered comparisons.

The I-SPY 1 TRIAL methods have been described in detail elsewhere [13 , 14 ] and was a collaboration of the American College of Radiology Imaging Network (ACRIN), Cancer and Leukemia Group B (CALGB), and Specialized programs of research excellence (SPORE). All patients gave written consent and had histologically confirmed invasive breast cancers measuring at least 3 cm by clinical examination or imaging, with no evidence of distant metastatic disease. Patients’ clinical stage 1 by exam was eligible if tumor size was >3 cm by imaging. Patients with T4 or inflammatory disease were eligible. The regimen of neoadjuvant chemotherapy included an initial anthracycline-based regimen after which patients either underwent surgery or received a taxane-based regimen prior to surgery.
Assays were conducted in nine laboratories. Data was integrated for central accession for analysis using NCICB’s caINTEGRATOR application (https://caintegrator-stage.nci.nih.gov/ispy/index2.jsp )—I-SPY 1 data version dated February 2011.

The murine and human breast carcinoma cell lines 4T1 and MCF-7, respectively, were acquired from the Chinese Academy of Sciences Shanghai Institute for Biological Sciences Cell Resource Center and incubated in RPMI 1640 and DMEM media. The anthracycline drug-resistant human breast carcinoma cell line, MCF-7/ADR, has been generously contributed by Professor Jianhua Xu, College of Pharmacy, Fujian Medical University, and cultivated in RPMI 1640 media. Moreover, the two media were enriched with 10% FBS, penicillin (100 U/mL), and streptomycin (100 mg/mL). Cell line culture was incubated at 37°C in a humidified setting with 5% CO2.

The proportion of patients who develop a cardiac event at 12 months will be estimated together with an exact 95% confidence interval. Based upon our preliminary data of early-stage HER2-positive patients treated with non-anthracycline trastuzumab-based regimens, the estimated cardiac event rate is 1.2% (95% CI 0.1–4.1%) [21 ]. The null hypothesis of the current study is that a reduced cardiotoxicity surveillance strategy is non-inferior to routine standard-of-care surveillance by a prespecified margin in the cardiac event rate of 2.9%. This non-inferiority margin corresponds to the difference between the observed cardiac event rate from our preliminary data and the upper bound of the 95% confidence interval. With 190 patients, we will have 84% power to reject the null hypothesis using a one-sided exact test with a significance level of 0.052. We will reject the null hypothesis if no more than 3 participants develop a cardiac event. If 4 or more cardiac events are observed during any point in the trial, the study will stop.

This is a single-arm prospective trial (ClinicalTrials.gov Identifier: NCT03983382) with a primary objective to evaluate the cardiac safety of a reduced cardiotoxicity surveillance strategy (every 6 months) in patients with HER2-positive breast cancer treated with a non-anthracycline HER2-targeted treatment regimen. Secondary objectives include the following: 1) to measure the change in LVEF and global longitudinal strain (GLS) after 6 and 12 months of treatment compared to baseline; 2) to estimate the incidence of asymptomatic LVEF decline; 3) to estimate the incidence of early interruption of HER2-targeted treatment; and 4) to determine feasibility of a reduced cardiotoxicity surveillance strategy.

Treatment Protocols
The study will be conducted in HER2-positive breast cancer patients (stage I-IV) receiving a non-anthracycline-based chemotherapy regimen in combination with a HER2-targeted agent (e.g. trastuzumab, pertuzumab, or ado-trastuzumab emtansine). The primary exclusion criteria are: (1) prior treatment with anthracyclines or HER2-targeted therapy; (2) baseline LVEF < 53% (or institutional lower limit of normal); (3) systolic or diastolic blood pressure ≥ 160 mmHg or ≥ 90 mmHg, respectively; and (4) history of heart failure, cardiomyopathy, or other significant CVD associated with increased cardiotoxicity risk (e.g. atrial fibrillation, atherosclerotic cardiovascular disease, significant valvular heart disease, etc.). Following approval by the primary medical oncologist, written informed consent will be obtained from each patient prior to study enrollment. The inclusion and exclusion criteria of this study are presented in Table 1 .
Main eligibility criteria
Inclusion criteria | Exclusion criteria |
---|---|
1. Female 2. Age ≥ 18 years 3. Pathologically confirmed HER2-positive invasive breast carcinoma (stage I-IV) 4. Anticipated treatment with HER2-targeted therapy for ≥ 12 months 5. Normal LV systolic function (LVEF ≥ institutional lower limit of normal) 6. Willing and able to provide written informed consent and comply with the requirements of the protocol | 1. Anticipated treatment with anthracycline chemotherapy 2. Prior treatment with anthracycline chemotherapy 3. History of cardiomyopathy, heart failure, or other clinically significant cardiovascular disease 4. Uncontrolled hypertension, defined as a systolic blood pressure ≥ 160 mmHg and/or diastolic blood pressure ≥ 90 mmHg |

The objective was to develop and externally validate a multivariable model to stratify patients with HER2+ AGA according to PFS/OS. Outcome variables were PFS and OS defined as the time in months between initiation of first-line chemotherapy and progression or death, respectively, censoring subjects alive at last follow-up.
Candidate predictors were selected after an exhaustive literature search, and after consultation with experts from the participating centres. No data-driven method was used in the final selection of variables.21 All covariates had to be available at the start of treatment (e.g. the primary tumour surgery variable was only considered when subjects had been exposed before the start of first-line treatment). The covariates considered in this model were age, Eastern Cooperative Oncology Group performance status (ECOG PS; ⩾2 versus 0–1), primary tumour location (oesophagus, GEJ, stomach), HER2 expression level (IHC 2+/FISH+ versus IHC 3+), Lauren subtype (intestinal versus diffuse and mixed), signet ring cells, histological grade (1, 2, versus 3), overall tumour burden (stratified into four categories,Table 1 ), neutrophil-to-lymphocyte ratio (NLR; non-linear, continuous), albumin, carcinoembryonic antigen, CEA (non-linear, continuous), primary tumour surgery, chemotherapy regimen (anthracycline-based triplets, carboplatin–5-fluorouracil, carboplatin–capecitabine, cisplatin–5-fluorouracil, docetaxel-containing regimens, 5-fluorouracil/oxaliplatin, capecitabine/oxaliplatin, capecitabine/cisplatin, others). Criteria to stratify the overall tumour burden (Table 1 ) have been used previously by our group.22 The OS analyses stratified by this variable on the entire cohort, as well as the Manchester series, suggest that these criteria are valid (Supplemental Annex Figure 1 ).
