Question · Q4 2025
Mason Carrico asked for Derek Maetzold's latest thoughts on the commercial strategy for the Dermatology team if a positive draft LCD for DecisionDx-SCC were published mid-year, specifically how reps' time would be split between melanoma, SCC, and the AD test. Mason Carrico also asked when NCCN typically updates guidelines for SCC and what new data was submitted ahead of the panel meeting that might not have been reviewed previously.
Answer
Derek Maetzold, Founder, President, and CEO of Castle Biosciences, described this as a 'very nice problem to have.' He indicated that if DecisionDx-SCC regains coverage, it would be folded back into sales commissions, but noted that reimbursement timing (up to a year) is a factor. He acknowledged the challenge of one person selling three tests extremely well and suggested that if Advance AD reimbursement grows as expected, the company might profitably expand its sales forces to handle all three opportunities (DecisionDx-Melanoma, Advance AD, and DecisionDx-SCC). Derek Maetzold stated that the submission likely included two papers on adjuvant radiation therapy responsiveness, published mid-to-Q3 2024, which missed the 2024 cutoffs. He expects the annual NCCN in-person meeting around May, with guideline updates potentially coming out between now and late April or May.
