Amendment Flag true  
Amendment Description Corbus Pharmaceuticals Holdings, Inc. (the “Company”) is filing this amendment (this “Amendment”) to its Quarterly Report on Form 10-Q for the quarter ended June 30, 2020 (the “Quarterly Report”) to revise a clerical error with respect to the status of the Company as a “non-accelerated filer.” The cover page of the Quarterly Report has been revised to indicate that the Company is an “accelerated filer.” In addition, this amendment is being filed to furnish Exhibit 101 (which was previously included in the Quarterly Report) formatted in iXBRL (Inline eXtensible Business Reporting Language), and Exhibit 104 (Cover Page Interactive Data File (formatted in iXBRL and contained in Exhibit 101)), which had been inadvertently omitted from the Quarterly Report. For the convenience of the reader, this report on Form 10-Q/A refiles in its entirety the Quarterly Report.  Additionally, this filing includes updated CEO and CFO certifications filed as Exhibits 31.1, 31.2, 32.1, 32.2. No other changes have been made to the Quarterly Report.
