Going Concern Disclosure [Abstract]  
The accompanying financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America, which contemplate continuation of the Company as a going concern. The ability of the Company to continue as a going concern is dependent upon developing products that receive regulatory approval and market acceptance. There is no assurance that these benchmarks will be realized. The financial statements do not include any adjustments that might result from the outcome of these uncertainties.
There is substantial doubt about the Company’s ability to continue as a going concern. From inception through August 31, 2017, the Company has incurred an accumulated deficit of $100,351,226. For the years ended May 31, 2017 and 2016, the Company had net losses of $4,563,721 and $9,415,450, respectively, and for the three months ended August 31, 2017, the Company had a net loss of $1,164,977. The Company utilized $3,936,796 and $4,279,100 of cash for operating activities for the years ended May 31, 2017 and 2016, respectively, and $880,125 during the three months ended August 31, 2017. As of August 31, 2017, the Company had cash and cash equivalents of $477,258 and negative net working capital of $89,384. The Company has incurred negative cash flow from operating activities since its inception. The Company has spent, and subject to obtaining additional financing, expects to continue to spend, substantial amounts in connection with executing its business strategy, including continued development efforts relating to PRTX-100.
The Company has no significant payments due on long-term obligations. However, the Company anticipates entering into significant contracts to perform product manufacturing and to conduct clinical trials in the future and that it will need to raise additional capital to fund the ongoing FDA regulatory approval process. If the Company is unable to obtain approval of its future IND applications or otherwise advance the FDA approval process, its ability to sustain its operations would be significantly jeopardized.
The most likely sources of additional financing include the sale of the Company’s equity or debt securities. On June 3, 2016, the Company filed Amendment #1 to the Registration Statement on Form S-1 with the U.S. Securities and Exchange Commission (SEC) (SEC File No. 333-206008), originally filed on July 31, 2015, with respect to a proposed public offering of Company securities.  There is no assurance that the Company will consummate a public offering of its securities, or any other offering.  Accordingly, additional capital that is required by the Company may not be available on reasonable terms, or at all.
