Item 1.01.

Entry Into a Material Definitive Agreement.

On January 16, 2013, PolyMedix, Inc., a Delaware corporation, referred to as the “Company,” and the Company’s wholly owned subsidiary, PolyMedix Pharmaceuticals, Inc., collectively referred to as the “Borrowers,” entered into a Second Amendment to Loan and Security Agreement with MidCap Financial SBIC, LP, a Delaware limited partnership, as administrative agent and lender. In the second amendment, among other things, the agent and lender agreed that during a fundraising period which ends on March 2, 2013, it will not deliver notice of an event of default to Borrowers or accelerate the Borrowers’ obligations under the loan documents based on facts known to it as of the date of the amendment, including, without limitation, the deterioration of the Borrowers’ cash position, or otherwise exercise any of its rights and remedies under the loan documents, so long as from and after the date of the amendment no event of default shall occur. In consideration, the Borrowers have granted the agent, for the benefit of the lender, a security interest in the Borrowers’ intellectual property. The amendment further provides that in the event that the Borrowers consummate one or more transactions which result in at least $18,500,000 in aggregate net proceeds to the Borrowers, the agent and lender will release the security interest in the Borrowers’ intellectual property. Except as expressly modified by the amendment, the loan and security agreement, as amended by the first amendment, remain in full force and effect in accordance with its terms and conditions. No assurance can be given that the Borrowers will consummate any transaction or that the net proceeds from any transactions will be sufficient to obtain the release of the security interest in the Borrowers’ intellectual property.

99.1	Press release dated January 23, 2013.

Forward-looking statements. This report contains forward-looking statements within the meaning of Section 27A of the Securities Act, as amended, Section 21E of the Securities Exchange Act of 1934, as amended, and the Private Securities Litigation Reform Act of 1995 that involve risks, uncertainties and assumptions that could cause the Company’s actual results and experience to differ materially from anticipated results and expectations expressed in the forward looking statements. PolyMedix has in some cases identified forward-looking statements by using words such as “anticipates,” “believes,” “hopes,” “estimates,” “looks,” “expects,” “plans,” “intends,” “goal,” “potential,” “may,” “suggest,” and similar expressions. Among other factors that could cause actual results to differ materially from those expressed in forward-looking statements are the Company’s need for, and the availability of, substantial capital in the future to fund its operations and research and development, the fact that the Company may not be successful in obtaining financing or completing an alternative transaction, and the fact that the Company’s compounds may not successfully complete pre-clinical or clinical testing, or be granted regulatory approval to be sold and marketed in the United States or elsewhere. You should not place undue reliance on any forward-looking statements. The Company undertakes no obligation to release publicly the results of any revisions to any such forward-looking statements that may be made to reflect events or circumstances after the date of this report or to reflect the occurrence of unanticipated events, except as required by applicable law or regulation.
