Registration Statement on Form S-1 (File No. 333-203317)

Dear Mr. Ingram:

Reference is made to our letter, filed as correspondence via EDGAR on June 8, 2015, in which we, as representative of the several underwriters of BioPharmX Corporation’s (the “Registrant”) proposed public offering of common stock, joined the Registrant’s request for acceleration of the effective date of the above-referenced Registration Statement for June 10, 2015, at 4:00 p.m. Eastern Time, or as soon thereafter as practicable, pursuant to Rule 461 promulgated under the Securities Act of 1933, as amended. The Registrant is no longer requesting that such Registration Statement be declared effective at this time, and we hereby formally withdraw our request for acceleration of the effective date.
