This is a double-blinded randomized controlled clinical trial that aims to study if desloratadine can reduce rates of peripheral neuropathy development in patients with breast cancer receiving taxane chemotherapy. Researchers will compare desloratadine to a placebo (look-alike substance with no drug) and use validated neurotoxicity and quality of life questionnaires to determine if desloratadine can be used to prevent or make taxane induced peripheral neuropathy (TPIN) symptoms better.
Taxanes are frequently incorporated in first line chemotherapy regimens for breast cancer. Although taxane induces peripheral neuropathy (TIPN) is among the most common side effects of taxane treatment, currently there are no therapies that have consistently proven to be effective in preventing TIPN. TIPN involves a complex interplay of mechanisms which are not yet fully understood. However, neuroinflammation has been shown to be a critical component of the pathophysiology of TIPN. As a result, the discovery of novel therapies that can safely and efficiently attenuate the inflammatory drivers of TIPN and thus prevent the onset of bothersome and potentially disabling neuropathy, represents a unique opportunity to make a meaningful impact on the lives of breast cancer patients. Desloratadine has shown promise for preventing TIPN in animal models, but based on available information has not yet been tested in humans. This study aims to build on this research by investigating the efficacy of desloratadine in preventing and ameliorating TIPN symptoms as assessed by validated neurotoxicity and quality of life questionnaires. Additionally, this study seeks to expand current knowledge about the role of inflammatory biomarkers as predictive markers of TIPN development. This study will investigate a broad subset of pro and anti-inflammatory cytokines, many of which have been previously shown to be mediated by the Histamine H1 Receptor (HRH1) and 5-HT 2A /c-Fos/NLRP3/IL-1β pathways. This study will measure histamine and nitric oxide levels, which have been show in-vivo to induce neuroinflammation and be upregulated in TIPN. This study will also assess nerve growth factor (NGF) and neurofilament light polypeptide (NF-L), which have protective, regenerative, nociceptive, and structural function in neurons. These biomarkers have shown to correlate with severity of TIPN, but thus far predictive utility is lacking and merits more research. Finally, this study aims to build upon current research regarding the human microbiome and its role in mediating inflammation and the onset of TIPN. Based on current knowledge, no prior study has investigated whether attenuation of chemotherapy induced inflammation via an antihistamine can prevent dysbiosis and help minimize the effect altered gut flora has on promoting further inflammation. Desloratadine is a safe and inexpensive drug. This study is using 5mg PO dosing, every other day, because this is the standard dose used clinically for allergic rhinitis and chronic urticaria. Based on the effectiveness of loratadine in improving patient reported outcomes from vinca alkaloid induced neuropathy, and because of promising results of desloratadine in preventing and alleviating TIPN in mouse models, it is hypothesized that desloratadine will be an effective therapy to prevent TIPN in patients with breast cancer who receive adjuvant taxane-based chemotherapy regimens. Furthermore, it is also hypothesized that inflammatory biomarkers and gut microbiome signatures are associated with the development of TIPN. The effect of desloratadine in modulating such biomarkers will be monitored. This double-blinded randomized controlled trial design will help mitigate bias in patient reported outcomes and clinician assessments. If the primary objective is met, desloratadine could potentially represent a safe, cost effective, and accessible strategy to prevent TIPN.
Desloratadine 5mg PO every other day for 12 weeks. Desloratadine is a long- acting tricyclic histamine antagonist with selective H1-receptor histamine antagonist activity. Desloratadine inhibited histamine release from human mast cells.
Placebo daily PO for 12 weeks. Placebo is a lactose filler covered by a capsule.

Change in Functional Assessment of Cancer Therapy (FACT)/Gynecologic Oncology Group (GOG)-Neurotoxicity (NTX) Subscale Version 4 (FACT-GOG-NTX) neuropathy score
The patient-related-outcome based neurotoxicity will be assessed using the 11 items about neurotoxicity in the FACT/GOG-NTX questionnaire. For the FACT/GOG-NTX neuropathy, each item is scored from 0-4, and the neurotoxicity total score is the sum of the scores for the 11 items, and ranges from 0 to 44. Lower values of the FACT/GOG-NTX neurotoxicity total score indicate higher neurotoxicity. The FACT/GOG-NTX neurotoxicity total score will be analyzed as a continuous variable. Proper transformation to improve normality will be used if needed. Change in FACT/GOG-NTX neuropathy score will be defined as the difference in score values between baseline versus after 12 weeks of taxane chemotherapy.
Time frame: From baseline to after completion of 12 weeks of taxane chemotherapy
Rate of grade 2-4 TIPN assessed by treating physician
The rate of grade 2-4 TIPN will be assessed by treating physician using CTCAE V5.0 while on taxane treatment. Patients will be coded as having the event if grade 2-4 neuropathy occurred at any time during the observation period. Patients without neuropathy or with maximum of grade 1 neuropathy will be coded as having no event. Of note, only neuropathy with a treatment relationship classified as possibly, probably, or definitely will be considered as taxane-induced neuropathy, whereas neuropathy with a treatment relationship classified as unrelated or unlikely will not be considered an event in the study design.
Time frame: After completion of 12 weeks of taxane chemotherapy and at 24 weeks and 12 months after completing taxane chemotherapy
Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE) survey score
The PRO-CTCAE includes a two-item questionnaire that focuses on taxane-induced peripheral neuropathy (TIPN) in which each item is scored 0 to 4 and a three-item questionnaire that focuses on general pain in which each item is scored 0 to 4. Scores from the two questionnaires are composited yielding an overall possible scoring range of 0-20, such that higher scores represent a patient's self-reported experience of the frequency, severity, and impact of neuropathy and pain on daily activities.

Change in Functional Assessment of Cancer Therapy/Gynecologic Oncology Group - Neurotoxicity (FACT-GOG-NTX) quality of life survey score
The FACT/GOG-NTX quality of life survey score contains 27 questions evaluating 4 domains of quality of life. Each question is scored 0 to 4. The physical wellbeing domain has 7 questions, and the total score ranges from 0-28. The social family well-being domain has 7 questions, and the total score ranges from 0-28. The emotional well-being domain has 6 questions, and the total score ranges from 0-24. The functional well-being score has 7 questions, and the total score ranges from 0-28. The total score for each domain will be summarized and reported as a continuous variable. Researchers will define change in each domain score as the difference in score values between baseline vs. after 12 weeks of taxane chemotherapy.
Time frame: From baseline to the completion of 12 weeks of taxane chemotherapy
Change in Patient-Reported Outcomes Measurement Information Systems (PROMIS) 29 v2.1 survey score
The PROMIS 29 survey contains items from seven PROMIS domains (Depression, Anxiety, Physical Function, Pain Interference, Fatigue, Sleep Disturbance, and Ability to Participate in Social Roles and Activities). The PROMIS-29 assesses 7 domains with 4 questions each. There is an additional question that assesses pain intensity 0-10 on numeric rating scale. Tables in the protocol will be used to translate the total raw score into a T-score for each participant. The T-score rescales the raw score into a standardized T-score with a mean of 50 and a standard deviation (SD) of 10. Therefore, a person with a T-score of 40 is one SD below the mean.
Time frame: From baseline to the completion of 12 weeks of taxane chemotherapy
European Organisation of Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ) - Chemotherapy-induced Peripheral Neuropathy twenty-item scale (CIPN20) (EORTC QLQ CIPN20) survey score
The EORTC CIPN20 survey contains 20 items that address neuropathy symptoms using a 4-point Likert type scale (1 = "not at all," 2 = "a little," 3 = "quite a bit," and 4 = "very much"). based on 7-day recall. Given that the patient population in the study is expected to be predominately female and have significant heterogeneity in motor vehicle use, items 19 ("Did you have difficulty using the pedals?") and 20 ("Did you have difficulty getting or maintaining an erection?") will be omitted. The assessment thus can be divided into three subscales: sensory (9 items), motor (7 items), and autonomic symptoms (2 items). Each subscale is converted into a score ranging from 1-36, 1-28, and 1-8, respectively. All scales are linearly converted to a 0-100 total score where a higher score indicates worse symptoms.
Time frame: 12 weeks after the completion of taxane chemotherapy
Rate of permanent discontinuation of taxane due to TIPN
The rate of permanent discontinuation of taxane will be calculated as the percentage of patients who discontinue taxane chemotherapy before 12 weeks due to TIPN. Results will be summarized by study arm.
Time frame: From baseline up to week 12 of taxane chemotherapy
Rate of taxane dose interruption or dose reduction due to TIPN
The rate of taxane dose interruption or dose reduction will be calculated by the percentage of patients who experience taxane dose interruption or reduction due to TIPN before 12 weeks of taxane treatment. Results will be summarized by study arm.
Time frame: From baseline up to week 12 of taxane chemotherapy
Rate of pathological complete response (pCR)
The rate of pathological complete response will be evaluated using the safety of adding desloratadine to taxane-based regimens on breast cancer outcomes. Pathological complete response(pCR), defined as no evidence of invasive carcinoma on breast or axilla after neoadjuvant chemotherapy (ypT0/Tis,ypN0), proposed as a surrogate of overall survival, will be summarized by study arm.
Time frame: After completion of 12 weeks of taxane chemotherapy
