Business</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-indent:24.5pt;margin:0pt 0pt 12pt 0pt;">Cara Therapeutics, Inc., or the Company, is a commercial-stage biopharmaceutical corporation formed on July 2, 2004. The Company is leading a new treatment paradigm to improve the lives of patients suffering from pruritus. The Company’s primary activities to date have been organizing and staffing the Company, developing its lead product and product candidates, including conducting preclinical studies and clinical trials of difelikefalin-based product candidates, and raising capital.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-indent:24.5pt;margin:0pt;">In August 2021, the Company received U.S. Food and Drug Administration, or FDA, approval for KORSUVA<span style="font-family:'Segoe UI';">®</span><sup style="font-size:7.5pt;line-height:100%;top:0pt;vertical-align:top;"> </sup>(difelikefalin) injection, or KORSUVA injection, for the treatment of moderate-to-severe pruritus associated with chronic kidney disease in adults undergoing hemodialysis. Commercial launch of KORSUVA injection began in the United States in April 2022 and the Company began recording the associated profit-sharing revenues in the second quarter of 2022.</p><p style="font-family:'Times New Roman','Times','serif';font-size:12pt;text-indent:24.5pt;margin:0pt;"><span style="font-size:10pt;text-decoration-color:#000000;visibility:hidden;"></span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-indent:24.5pt;margin:0pt 0pt 12pt 0pt;">In April 2022, the European Commission granted marketing authorization to difelikefalin injection under the brand name Kapruvia® (difelikefalin), or Kapruvia, for the treatment of moderate-to-severe pruritus associated with chronic kidney disease in adult hemodialysis patients. The marketing authorization approved Kapruvia for use in all member states of the European Union, or EU, as well as Iceland, Liechtenstein, and Norway. Kapruvia was also approved in the United Kingdom in April 2022. Commercial launches in Austria, Germany, Sweden, and Denmark have commenced, with the remaining EU countries to launch in 2023. In August 2022, as part of the Access Consortium, difelikefalin injection was approved in Switzerland under the brand name Kapruvia, as well as Singapore and Canada under the brand name KORSUVA. In November 2022, difelikefalin injection was approved in the last Access Consortium country, Australia, under the brand name KORSUVA.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-indent:24.5pt;margin:0pt;">In 2018, the Company entered into a licensing and collaboration agreement with a joint venture between Vifor Pharma Group and Fresenius Medical Care Renal Pharmaceutical Ltd., or Vifor Fresenius Medical Care Renal Pharma Ltd., that provides full commercialization rights of Kapruvia, and where applicable KORSUVA, to Vifor Fresenius Medical Care Renal Pharma Ltd. worldwide (excluding the United States, Japan, and South Korea). In markets outside of the United States, the Company is eligible to receive tiered double-digit royalty payments based on annual net sales, as defined in the agreement with Vifor Fresenius Medical Care Renal Pharma Ltd., of difelikefalin injection in the licensed territories. In the U.S. market, the agreement with Vifor Fresenius Medical Care Renal Pharma Ltd. provides that Vifor Fresenius Medical Care Renal Pharma Ltd. will promote difelikefalin injection in the dialysis clinics of Fresenius Medical Care North America, or FMCNA, under a profit-sharing arrangement, whereby the Company is generally entitled to 50% of the annual net profits (as defined in the agreement with Vifor Fresenius Medical Care Renal Pharma Ltd.) based on net FMCNA clinic sales (as defined in the agreement with Vifor Fresenius Medical Care Renal Pharma Ltd.) and Vifor Fresenius Medical Care Renal Pharma Ltd. is entitled to 50% of such net profits, subject to potential adjustments in a calendar year based on certain conditions (see Note 12,<i style="font-style:italic;"> Collaboration and Licensing Agreements</i>). </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-indent:24.5pt;margin:0pt;"><span style="visibility:hidden;"></span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-indent:24.5pt;margin:0pt;">In 2020, the Company entered into a second licensing and collaboration agreement, along with stock purchase agreements, with Vifor (International) Ltd., or Vifor International, that provides full commercialization rights of KORSUVA injection to Vifor International in dialysis clinics in the United States under a profit-sharing arrangement, whereby total net sales of KORSUVA injection in the United States, as recorded by Vifor International, are reduced by Vifor International’s cost of goods sold, or COGS, as well as a marketing and distribution fee owed by the Company based on the level of annual net sales, and the resulting amount was to be shared according to a 60% (Company)/40% (Vifor International) profit split (excluding sales to Fresenius Medical Center dialysis clinics, compensation for which is governed by the agreement with Vifor Fresenius Medical Care Renal Pharma Ltd.), subject to potential temporary adjustment in future years based on certain conditions (see Note 12,<i style="font-style:italic;"> Collaboration and Licensing Agreements</i>). </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-indent:24.5pt;margin:0pt;"><span style="visibility:hidden;"></span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-indent:24.5pt;margin:0pt;"><span style="white-space:pre-wrap;"> In May 2022, Vifor International assigned its rights and obligations under the license agreement and a supply agreement, as permitted under the agreements, to Vifor Fresenius Medical Care Renal Pharma Ltd. The Company’s rights and obligations under these agreements were unaffected by this assignment, and the assignment did not affect the Company’s economic rights under the agreements with Vifor International. </span></p><p style="font-family:'Times New Roman','Times','serif';font-size:12pt;margin:0pt;"><span style="font-size:10pt;text-decoration-color:#000000;visibility:hidden;"></span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-indent:24.5pt;margin:0pt;">In August 2022, Vifor Pharma Group (which includes Vifor International) was acquired by CSL Limited and subsequently renamed CSL Vifor as part of the acquisition. The acquisition of Vifor Pharma Group did not affect any of the Company’s rights and obligations pursuant to these agreements.</p><p style="font-family:'Times New Roman','Times','serif';font-size:12pt;text-indent:24.5pt;margin:0pt;"><span style="font-size:10pt;text-decoration-color:#000000;visibility:hidden;"></span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-indent:24.5pt;margin:0pt 0pt 12pt 0pt;">The Company also has a license agreement with Maruishi Pharmaceutical Co. Ltd., or Maruishi, under which the Company granted Maruishi an exclusive license to develop, manufacture, and commercialize drug products containing difelikefalin for acute pain and/or uremic pruritus in Japan. In September 2022, Maruishi submitted a New Drug Application in Japan for approval of difelikefalin injection for the treatment of pruritus in hemodialysis patients (see Note 12, <i style="font-style:italic;">Collaboration and Licensing Agreements)</i>.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-indent:24.5pt;margin:0pt 0pt 12pt 0pt;">As of December 31, 2022, the Company has raised aggregate net proceeds of approximately $519,600 from several rounds of equity financing, including its initial public offering, or IPO, which closed in February 2014 and four follow-on public offerings of common stock, which closed in July 2019, July 2018, April 2017 and August 2015, respectively, and the issuance of convertible preferred stock and debt prior to the IPO. Including profit share revenue and royalties, the Company has also earned approximately $266,790 under its license and supply agreements for difelikefalin, primarily with CSL Vifor, Maruishi, and Chong Kun Dang Pharmaceutical Corp., or CKDP, and an earlier product candidate for which development efforts ceased in 2007. In October 2021, the Company received net proceeds of $44,969 from the issuance and sale of 3,282,391 shares of the Company’s common stock to Vifor International in connection with U.S. regulatory approval for KORSUVA injection in August 2021. Additionally, in October 2020, the Company received net proceeds of $38,449 from the issuance and sale of 2,939,552 shares of the Company’s common stock to Vifor International in connection with the Company’s license agreement with Vifor International. Furthermore, in May 2018, the Company received net proceeds of $14,556 from the issuance and sale of 1,174,827 shares of the Company’s common stock to Vifor International in connection with the Company’s license agreement with CSL Vifor (see Notes 10, <i style="font-style:italic;">Shareholders’ Equity</i> and 12, <i style="font-style:italic;">Collaboration and Licensing Agreements</i>).</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-indent:24.5pt;margin:0pt 0pt 12pt 0pt;">As of December 31, 2022, the Company had unrestricted cash and cash equivalents and marketable securities of $156,749 and an accumulated deficit of $566,232. The Company has incurred substantial net losses and negative cash flows from operating activities in nearly every fiscal period since inception and expects this trend to continue for the foreseeable future. The Company recognized net losses of $85,474 and $88,441 for the years ended December 31, 2022 and 2021, respectively, and recognized net income of $8,410 for the year ended December 31, 2020. The Company had net cash used in operating activities of $78,730, $60,087, and $5,487 for the years ended December 31, 2022, 2021 and 2020, respectively.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-indent:24.5pt;margin:0pt 0pt 12pt 0pt;">The Company is subject to risks common to other life science companies including, but not limited to, uncertainty of product development and commercialization, lack of marketing and sales history, development by its competitors of new technological innovations, dependence on key personnel, market acceptance of products, product liability, protection of proprietary technology, ability to raise additional financing, and compliance with FDA and other government regulations. If the Company does not successfully commercialize KORSUVA injection, Kapruvia or any of its other product candidates, it will be unable to generate additional recurring product revenue or achieve profitability.</p>

The more significant estimates include the fair value of marketable securities that are classified as level 2 of the fair value hierarchy, the amount and periods over which certain revenues will be recognized, including licensing and collaborative revenue recognized from non-refundable up-front and milestone payments, related party accounts receivable reserve, as applicable, inventory valuation and related reserves, research and development, or R&D, clinical costs and accrued research projects included in prepaid expenses and accounts payable and accrued expenses, the amount of non-cash compensation costs related to share-based payments to employees and non-employees, the incremental borrowing rate used in lease calculations and the likelihood of realization of deferred tax assets.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-indent:24.5pt;margin:0pt 0pt 12pt 0pt;">The COVID-19 pandemic and geopolitical tensions, such as Russia’s incursion into Ukraine, resulted in a global slowdown of economic activity, decades-high inflation, rising interest rates, and a potential recession in the United States. Estimates and assumptions about future events and their effects cannot be determined with certainty and therefore require the exercise of judgment. As of the date of issuance of these financial statements, the Company is not aware of any specific event or circumstance that would require the Company to update its estimates, assumptions and judgments or revise the reported amounts of assets and liabilities or the disclosure of contingent assets and liabilities. These estimates, however, may change as new events occur and additional information is obtained, and are recognized in the financial statements as soon as they become known.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-indent:24.5pt;margin:0pt 0pt 12pt 0pt;">Actual results could differ materially from the Company’s estimates and assumptions. </p>

The Company invests its cash reserves in money market funds or high-quality marketable securities in accordance with its investment policy. The stated objectives of its investment policy are to preserve capital, provide liquidity consistent with forecasted cash flow requirements, maintain appropriate diversification and generate returns relative to these investment objectives and prevailing market conditions. The Company’s investment policy includes guidelines on acceptable investment securities, limits interest-bearing security investments to certain types of debt and money market instruments issued by the U.S. government and institutions with investment grade credit ratings and places restrictions on maturities and concentration by asset class and issuer. The Company’s cash and cash equivalents and marketable securities are held by three major financial institutions. In accordance with the Company’s policies, the Company monitors exposure with its counterparties. The Company also maintains deposits in federally insured financial institutions in excess of federally insured limits. The Company has not experienced any losses in such accounts and management believes that the Company is not exposed to significant credit risk due to the financial position of the depository

manufacture KORSUVA injection active pharmaceutical ingredient, or API, finished drug product, and finished goods. If any of the Company’s suppliers were to limit or terminate production or otherwise fail to meet the quality or delivery requirements to satisfy the supply commitments, the process of locating and qualifying alternate sources would require up to two years, during which time production could be delayed. Such delays could have a material adverse effect on the Company’s business, financial position, and results of operations.</p>
