Nature of Operations [Abstract]
Nature of Operations	Note 1 - Nature of Operations Edge Therapeutics, Inc. (the "Company") is a clinical-stage biotechnology company that discovers, develops and seeks to commercialize novel, hospital-based therapies capable of transforming treatment paradigms in the management of acute, life-threatening neurological conditions. The Company’s product candidates utilize its proprietary, programmable, biodegradable polymer-based development platform (the Precisa^TM development platform), a novel delivery mechanism that enables targeted and sustained drug exposure and avoids the dose-limiting side effects associated with the current standard of care. From the Company’s inception, it has devoted substantially all of its efforts to business planning, engaging regulatory, manufacturing and other technical consultants, acquiring operating assets, planning and executing clinical trials and raising capital. The Company’s future operations are highly dependent on a combination of factors, including (i) the success of its research and development; (ii) the development of competitive therapies by other biotechnology and pharmaceutical companies, and, ultimately; (iii) regulatory approval and market acceptance of the Company’s proposed future products. On September 21, 2015, the Company effected a reverse stock split of the Company’s common stock at a ratio of 1-for-1.3681 shares. The par value and authorized shares of common stock and convertible preferred stock were not adjusted as a result of the reverse stock split. All issued and outstanding common stock, options and warrants to purchase common stock and per share amounts contained in the financial statements have been retroactively adjusted to reflect the reverse stock split for all periods presented. The financial statements have also been retroactively adjusted to reflect adjustments to the conversion price for each series of convertible preferred stock effected in connection with the reverse stock split. On October 6, 2015, the Company completed an initial public offering (the “IPO”) of 8,412,423 shares of its common stock which included 1,097,272 shares of common stock issued upon the exercise in full by the underwriters of their over-allotment option at a price of $11.00 per share for aggregate gross proceeds of $92.5 million. The Company received approximately $83.2 million in net proceeds after deducting underwriting discounts and commissions and other offering costs of approximately $9.3 million. Immediately prior to the closing of the IPO, all of the outstanding shares of convertible preferred stock, including shares for accrued dividends, automatically converted into 18,566,856 shares of common stock at the applicable conversion ratio then in effect. As of October 31, 2015, there were no shares of preferred stock outstanding. In connection with the IPO, the Company amended and restated its Seventh Amended and Restated Certificate of Incorporation to change the authorized capital stock to 75,000,000 shares designated as common stock and 5,000,000 shares designated as preferred stock, all with a par value of $0.00033 per share.

Edge Therapeutics, Inc. (the "Company") is a clinical-stage biotechnology company that discovers, develops and seeks to commercialize novel, hospital-based therapies capable of transforming treatment paradigms in the management of acute, life-threatening neurological conditions.
