This phase II trial studies whether a prior germline predictor of taxane-induced peripheral neuropathy (TIPN) can help identify a subgroup of patients who are at higher risk of chemotherapy-induced peripheral neuropathy in African American patients with stages I-III breast cancer. The study also investigates whether docetaxel maybe work better than paclitaxel with regard to TIPN rate/severity and dose reductions.
PRIMARY OBJECTIVES: I. Prospectively validate a prior germline predictor of TIPN using the Common Terminology Criteria for Adverse Events (CTCAE). Specifically, this study will demonstrate that patients with a high-risk TIPN genotype have significantly more grade 2-4 TIPN than patients with a low risk genotype. SECONDARY OBJECTIVES: I. Validate a prior germline predictor of TIPN using the Functional Assessment of Cancer Therapy (FACT)/Gynecologic Oncology Group (GOG)-Neurotoxicity (NTX) neurotoxicity subscale in Arm A. II. Compare grade 2-4 TIPN based on CTCAE between weekly paclitaxel (Arm A) versus (vs.) every three-week docetaxel (Arm B). III. Prospectively confirm dose reductions due to TIPN are lower for every three-week docetaxel compared with weekly paclitaxel in a prospective cohort of patients of African ancestry. IV. Prospectively confirm dose reductions due to any cause are lower for every three-week docetaxel compared with weekly paclitaxel in a prospective cohort of patients of African ancestry. V. Assess the ability of the high-risk genotype to predict TIPN risk for docetaxel. EXPLORATORY OBJECTIVES: Correlative Study Objectives: I. Identify novel markers of TIPN and elucidate the mechanism. II. Whole genome sequencing of germline blood to evaluate for additional predictors of TIPN. III. Create induced pluripotent stem cell (iPSC) derived neurons from patient samples. IIIa. Evaluate whether clinical findings can be mimicked in vitro. IIIb. Evaluate gene expression (ribonucleic acid \[RNA\] sequencing \[seq\]) and the epigenome at baseline versus after exposure in those prone to TIPN versus those not. IV. Create a biorepository of patient derived samples for future translational research. Patient-Reported Outcome Objectives: I. Compare Grade 2-4 TIPN (moderate to life threatening) based on Patient Reported Outcomes (PRO)-CTCAE items between weekly paclitaxel (Arm A) vs. every three-week docetaxel (Arm B). II. Prospectively compare FACT/GOG-NTX Health-Related Quality of Life (HRQoL) subscale, Patient-Reported Outcomes Measurement Information System (PROMIS) Physical Function version (v.)2 Short Form (SF) 10a, scores between every three-week docetaxel and weekly paclitaxel and between high risk and low risk genotypes (Arm A) in a cohort of African ancestry. III. Compare the impact on financial toxicity (Comprehensive Score for Financial Toxicity \[COST\] scores) for every three-week docetaxel compared with weekly paclitaxel. IV. Examine associations between social determinants of health (zip code, marital status, education, income \& insurance status) and dose reductions and treatment discontinuation. OUTLINE: Patients are assigned to 1 of 2 arms. ARM A: Patients receive paclitaxel intravenously (IV) over 3 hours once weekly. Treatment repeats every 21 days for 4 cycles in the absence of disease progression or unacceptable toxicity. Patients may also receive trastuzumab and/or pertuzumab per institution routine care per treating physician?s discretion. ARM B: Patients receive docetaxel IV over 1 hour once every 3 weeks. Treatment repeats every 21 days for 4-6 cycles in the absence of disease progression or unacceptable toxicity. Patients may also receive cyclophosphamide, doxorubicin, trastuzumab, and/or pertuzumab per institution routine care per treating physician?s discretion. After completion of study treatment, patients are followed up every 3 months for 2 years and then every 6 months for 3 years.

Percentage of Participants With Grade 2-4 Taxane-Induced Peripheral Neuropathy (TIPN) by Genotype Risk Group in Arm A
Grade 2-4 TIPN was assessed by treating physician using National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE) version 4.0. All patients who started protocol therapy on arm A (paclitaxel) were included in the analysis. The percentage of participants with grade 2-4 TIPN was calculated based on binomial distribution and was compared between high-risk vs low-risk genotype groups using Fisher exact test. Genotype risk group (high vs. low) was determined by genotyping. High-risk genotype was defined by FCAMR GG genotype (homozygous wild type) or SBF2 mutated. Low-risk genotype was defined by carriage of at least one variant allele in FCAMR (AG or AA) and SBF2 wild-type status.
Time frame: assessed at baseline, an end of each cycle, at 6 months and 1 year post registration
Patient-Reported Neuropathy Score Change Between Baseline and End of Treatment by Genotype Risk Group in Patients on Arm A
The patient-reported neurotoxicity was assessed using the 11 items about neurotoxicity in the Functional Assessment of Cancer Therapy/Gynecologic Oncology Group - Neurotoxicity (FACT/GOG-Ntx) questionnaire (i.e., FACT/GOG-Ntx additional concerns subscale). The neurotoxicity total score was the sum of the scores for the 11 items, ranging from 0 to 44. Higher values of the FACT/GOG-Ntx neurotoxicity total score indicate less neurotoxicity. The FACT/GOG-Ntx neurotoxicity total score change between the baseline and at end of treatment (negative value indicates worsening symptom, positive value indicates improving symptom) was calculated and compared using two-sample t test. Genotype risk group (high vs. low) was determined by genotyping. High-risk genotype was defined by FCAMR GG genotype (homozygous wild type) or SBF2 mutated. Low-risk genotype was defined by carriage of at least one variant allele in FCAMR (AG or AA) and SBF2 wild-type status.
Time frame: assessed at baseline and at end of treatment, an average of 3 months
Percentage of Participants With Grade 2-4 TIPN Based on CTCAE Between Arm A and Arm B
Grade 2-4 TIPN was assessed by treating physician using CTCAE version 4.0. All patients who started protocol therapy were included in the analysis. The percentage of participants with grade 2-4 TIPN was calculated based on binomial distribution and was compared between treatment arms using Fisher exact test.
Time frame: assessed at baseline, an end of each cycle, at 6 months and 1 year post registration
Percentage of Participants With Dose Reduction Due to TIPN Between Arm A and Arm B
The percentage of patients with dose reduction due to TIPN was calculated as number of patients with dose reduction due to peripheral neuropathy for any dose of any cycle divided by total number of patients who started protocol therapy. The percentages were calculated along with exact 95% CI based on binomial distribution and were compared between arms using Fisher exact test.
Time frame: Dose reduction due to TIPN was assessed at end of each cycle, up to 4 cycles in arm A and 6 cycles in arm B
Percentage of Participants With Dose Reduction Due to Any Reason Between Arm A and Arm B
The percentage of patients with dose reduction due to any reason was calculated as number of patients with any dose reduction for any dose of any cycle, regardless of the reason, divided by total number of patients who started protocol therapy. The percentages were calculated along with exact 95% CI based on binomial distribution and were compared between arms using Fisher exact test.
Time frame: Dose reduction due to any reason was assessed at end of each cycle, up to 4 cycles in arm A and 6 cycles in arm B
Percentage of Participants With Grade 2-4 TIPN by Genotype Risk Group in Arm B
Grade 2-4 TIPN was assessed by treating physician using CTCAE version 4.0. All patients who started protocol therapy on arm B were included in the analysis. The percentage of participants with grade 2-4 TIPN was calculated based on binomial distribution and was compared between high-risk vs low-risk genotype groups using Fisher exact test. Genotype risk group (high vs. low) was determined by genotyping. High-risk genotype was defined by FCAMR GG genotype (homozygous wild type) or SBF2 mutated. Low-risk genotype was defined by carriage of at least one variant allele in FCAMR (AG or AA) and SBF2 wild-type status.
Time frame: assessed at baseline, at end of each cycle, at 6 months and 1 year post registration
