Registration Statement on Form S-3

File No. 333-212015

Ladies and Gentlemen:

Pursuant to Rule 461 of the General Rules and Regulations under the Securities Act of 1933, as amended, BioPharmX Corporation (the “Company”) respectfully requests that the effective date of the registration statement referred to above be accelerated so that it will become effective at 4:30 p.m., Eastern Daylight Time, on Wednesday, June 29, 2016, or as soon thereafter as possible.

The Company acknowledges the following:

·should the Commission or the staff, acting pursuant to delegated authority, declare the filing effective, it does not foreclose the Commission from taking any action with respect to the filing;

·the action of the Commission or the staff, acting pursuant to delegated authority, in declaring the filing effective, does not relieve the company from its full responsibility for the adequacy and accuracy of the disclosure in the filing; and

·the company may not assert staff comments and the declaration of effectiveness as a defense in any proceeding initiated by the Commission or any person under the federal securities laws of the United States.

Very truly yours,
BioPharmX Corporation
