Background: Adjuvant chemotherapy decreases the risk of recurrence. However, it has distressing side effects, including alopecia. There are no randomized trials assessing modern scalp cooling to prevent alopecia, and success rates in non-randomized trials have varied. Methods: We conducted a multi-center randomized trial to evaluate the safety and efficacy of the Orbis Paxman Hair Loss Prevention System (OPHLPS) in reducing chemotherapy-induced alopecia. Women with stage I-II breast cancer planned to receive anthracycline- or taxane- based chemotherapy for at least four cycles were eligible and randomized in a 2:1 ratio to scalp-cooling or control. Scalp-cooling was done with the OPHLPS 30 minutes prior to, during and 90 minutes after each chemotherapy. The primary efficacy endpoints were hair preservation and device safety. We planned to enroll 235 subjects to provide 85% power to detect a 20% difference in hair preservation. Secondary endpoints included wig/scarf use and quality of life assessed by the EORTC QLQ-30, HADS and BIS. Subjects will be followed for 5 years for recurrence, overall survival, and site of recurrence. One interim analysis was planned to allow the study to stop early for efficacy after 142 subjects were enrolled and evaluable for the primary endpoint. To maintain the overall type 1 error rate, an O’Brien-Fleming spending function was used (interim boundary p = 0.0061). Results: This is the first randomized trial with modern scalp cooling in the world. For the interim analysis, 142 subjects were evaluable. Among them, 48 (50.5%) out of 95 in the cooling group and 0 (0%) out of 47 in the control group had hair preservation. The one-tailed p-value from the Fisher’s exact test is < 0.0001, which crosses the superiority boundary (p = 0.0061). Thus on 9/26/2016 the DSMB stopped the study early. The interim analysis was presented at SABCS 2016. There are 195 subjects enrolled on this clinical trial, and the final subject will be evaluable for the primary outcome February 2017. The final analysis will be presented. Conclusions: Our trial showed that scalp cooling using OPHLPS is highly effective in hair retention. Paxman Coolers has applied for FDA clearance for the OPHLPS based on the results of the interim analysis. Clinical trial information: NCT01986140
