Item 7.01 Regulation FD Disclosure.
On April 26, 2025, Protara Therapeutics, Inc. (the “Company” or “Protara”) issued a press release reporting new interim clinical data on the ongoing Phase 2 ADVANCED-2 trial program (the “Press Release”). A copy of the Press Release is furnished herewith as Exhibit 99.1 to this Current Report on Form 8-K.
On April 28, 2025, the Company also posted an investor presentation (the “Investor Presentation”) to the “Investors—Events and Presentations” section of the Company’s website at www.protaratx.com. The Investor Presentation will be used in connection with a conference call and webcast today, April 28, 2025, at 8:30 am ET, to review the clinical data presented during a poster session at the 2025 American Urological Association Annual Meeting in Las Vegas, Nevada (the “2025 AUA Conference”) and provides an update on the ongoing Phase 2 ADVANCED-2 trial program. A copy of the Investor Presentation is furnished herewith as Exhibit 99.2 to this Current Report on Form 8-K.
The information contained in Item 7.01 of this Current Report on Form 8-K, including Exhibits 99.1 and 99.2 attached hereto, is being furnished and shall not be deemed to be “filed” for the purposes of Section 18 of the Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section and shall not be incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as shall be expressly set forth by specific reference in such filing.
Item 8.01 Other Events.
On April 26, 2025, the Company presented updated results from its ongoing Phase 2 open-label ADVANCED-2 trial assessing intravesical TARA-002, the Company’s investigational cell-based therapy, in high-risk Non-Muscle Invasive Bladder Cancer (NMIBC) patients with carcinoma in situ, or CIS (± Ta/T1), who are Bacillus Calmette-Guérin (BCG)-Unresponsive or BCG-Naïve, at a poster session at the 2025 AUA Conference. A copy of the poster, which has been published to the “Investors—Events and Presentations” section of the Company’s website, is filed as Exhibit 99.3 to this Current Report on Form 8-K and is incorporated herein by reference.
BCG-Unresponsive Cohort
The BCG-Unresponsive dataset includes a total of five patients, all of whom were six- and nine-month evaluable, and three of whom were evaluable at 12 months as of an April 16, 2025 data cutoff. The complete response (CR) rate at any time in BCG-Unresponsive patients was 100% (5/5). The CR rate in BCG-Unresponsive patients was 100% (5/5) at six months, 80% (4/5) at nine months, and 67% (2/3) at 12 months.
BCG-Naïve Cohort
The BCG-Naïve dataset includes a total of 21 patients, including 16 evaluable at six months, eight at nine months, and seven at 12 months as of an April 16, 2025 data cutoff. The CR rate at any time in BCG-Naïve patients was 76% (16/21). The CR rate in BCG-Naïve patients was 63% (10/16) at six months, 63% (5/8) at nine months, and 43% (3/7) at 12 months.
Safety
The majority of adverse events were Grade 1 and transient with no Grade 3 or greater treatment-related adverse events (TRAEs) as assessed by study investigators. No patients discontinued treatment due to TRAEs. The most common adverse events were in line with typical responses to bacterial immunopotentiation, such as flu-like symptoms. The most common urinary symptoms reflect urinary tract instrumentation effects, such as bladder spasm, burning sensation, and urinary tract infection. Most bladder irritations resolved shortly after administration or within a few hours to a few days.

Forward-Looking Statements
Statements contained in this press release regarding matters that are not historical facts are "forward looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995. Protara may, in some cases, use terms such as “predicts,” “believes,” “potential,” “proposed,” “continue,” “designed,” “estimates,” “anticipates,” “expects,” “plans,” “intends,” “may,” “could,” “might,” “will,” “should” or other words or expressions referencing future events, conditions or circumstances that convey uncertainty of future events or outcomes to identify these forward-looking statements. Such forward-looking statements include but are not limited to, statements regarding Protara’s intentions, beliefs, projections, outlook, analyses or current expectations concerning, among other things: Protara’s business strategy, including its development plans for its product candidates and plans regarding the timing or outcome of existing or future clinical trials (including reporting data from approximately 25 6-month evaluable BCG-Unresponsive patients by the end of 2025); statements related to expectations regarding interactions with the U.S. Food and Drug Administration (FDA); Protara’s financial position; statements regarding the anticipated safety or efficacy of Protara’s product candidates; and Protara’s outlook for the remainder of the year and future periods. Because such statements are subject to risks and uncertainties, actual results may differ materially from those expressed or implied by such forward-looking statements. Factors that contribute to the uncertain nature of the forward-looking statements include: risks that Protara’s financial guidance may not be as expected, as well as risks and uncertainties associated with: Protara’s development programs, including the initiation and completion of non-clinical studies and clinical trials and the timing of required filings with the FDA and other regulatory agencies; general market conditions; changes in the competitive landscape; changes in Protara’s strategic and commercial plans; Protara’s ability to obtain sufficient financing to fund its strategic plans and commercialization efforts; having to use cash in ways or on timing other than expected; the impact of market volatility on cash reserves; failure to attract and retain management and key personnel; the impact of general U.S. and foreign, economic, industry, market, regulatory, political or public health conditions; and the risks and uncertainties associated with Protara’s business and financial condition in general, including the risks and uncertainties described more fully under the caption “Risk Factors” and elsewhere in Protara's filings and reports with the United States Securities and Exchange Commission. All forward-looking statements contained in this press release speak only as of the date on which they were made and are based on management's assumptions and estimates as of such date. Protara undertakes no obligation to update any forward-looking statements, whether as a result of the receipt of new information, the occurrence of future events or otherwise, except as required by law.
