Current report

To date, we have sold 200,817 shares pursuant the ATM Agreement for net proceeds of approximately $0.3 million, after deducting commissions of $15,400 and other offering expenses of $33,600. See Note 4 to our unaudited condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q.

Current report

On June 10, 2024, we reported positive results from our Phase 1 clinical trial with TH104. Results from healthy subjects demonstrated consistent pharmacokinetic (PK) profiles across buccal and intravenous routes of administration with a comparable safety and tolerability profile between routes of administration. This Phase 1 trial was a single-dose, single-center, open-label, randomized 2-way crossover study comparing 16 mg of TH104 with 1 mg intravenous nalmefene administered under fasting conditions, with a 7-day washout period between doses. Twenty healthy subjects were enrolled to complete both doses of the crossover design. All 20 subjects completed TH104 buccal dosing, while 19 of 20 subjects also completed the intravenous dosing. The primary objective was to evaluate the absolute bioavailability of TH104, as well as to assess safety and tolerability. Findings from the study indicated that the primary endpoint of the study which was absolute bioavailability (F) of TH104, or fraction (or percentage) of the administered dose absorbed into the systemic circulation compared to an equivalent intravenous dose of nalmefene, was 0.459 (45.9%). The median time to maximum concentration (Cmax) of TH104 was 2.0 hours, and mean half-life (T 1/2) as measured in the blood of subjects was 14 hours after a single buccal administration of TH104, compared to 9 hours for the 1mg intravenous dose of nalmefene. These data were consistent and within range of previous findings of nalmefene in the literature and the Company believes PK results from this Phase 1 trial show proportional kinetics consistent with published findings of oral and intravenous formulations, suggesting TH104 could be developed for once-daily dosing in a target population of moderate-to-severe chronic pruritus in PBC patients. The Phase 1 trial also demonstrated that a 16mg dose of TH104 had a comparable safety and tolerability profile to the FDA-approved 1mg dose of nalmefene intravenous formulation. Treatment emergent adverse events (TEAEs) in this study were reported in 8 subjects (40.0%) in the TH104 group and 7 subjects (36.8%) in the intravenous group. All reported TEAEs were considered mild in severity. The most frequently reported TEAE for both TH104 and intravenous treatments was dizziness (4 subjects in the TH104 group; 7 subjects in the intravenous group). TEAEs reported in at least 2 subjects in any treatment group were nausea (3 subjects in each group) and somnolence (3 subjects in each group). There were no serious adverse events reported during this study. No subjects discontinued the study due to adverse events. No subjects exhibited abnormal results for the visual examinations of the buccal mucosa pre- or post-dosing with TH104 buccal film.

Current report

On June 17, 2024, we reported positive Type C meeting feedback from the FDA for our Phase 2 clinical trial with TH104, confirming our plan to pursue a 505(b)(2) approval pathway, which permits inclusion of data from external studies when the active ingredient is already approved in the United States. The FDA also agreed that the nonclinical studies submitted to the FDA in advance of the meeting appear sufficient to support the proposed Phase 2 clinical trial. In addition, the FDA provided feedback on study design and certain recommendations regarding PBC patient inclusion, the primary endpoint to assess pruritus in these patients, and considerations for monitoring for adverse events in this patient population. We engaged and received positive feedback in March 2025 from the FDA regarding the additional proposed indication of temporary prophylaxis of respiratory and/or nervous system depression in military personnel and chemical incident responders entering an area contaminated with high-potency opioids (“PrHPO”), for which we submitted a PIND. With respect to our PIND for this additional proposed indication for TH104, the Company received positive feedback from the FDA regarding a regulatory pathway that will allow Tharimmune to submit a 505(b)(2) NDA for TH104. The FDA confirmed that no additional clinical trials will be required prior to NDA submission for this indication, which will be the lead program for the Company. Based on this interaction with FDA we plan to delay the Phase 2 trial with TH104 in moderate-to-severe chronic pruritus in PBC patients until after planning and completing a hepatic impairment study. Due to the positive interaction with the FDA allowing for a 505(b)2 NDA application for PrHPO with no further clinical studies, we designated PrHPO as the lead program for the Company.

Comparison of the Three Months Ended March 31, 2025 and 2024

Current report

The following table sets forth key components of our results of operations for the three months ended March 31, 2025 and 2024.

Current report

Interest income decreased by $82,458, or 86%, to $13,436 for the three months ended March 31, 2025 from $95,894 for three months ended March 31, 2024. The decrease in interest income was primarily due to the decrease in cash March 2024 to March 2025.

Current report

In April 2025, we raised gross proceeds of $0.26 million pursuant to the ATM Agreement from the sale of 160,817 shares of our common stock at an average price of $1.61 per share. The net proceeds from the sales were $0.25 million, after deducting sales agent commissions of $12,900 and other offering fees of $33,300.
Removed paragraphs (12)

Previous report

As part of the ABSI Agreement, on July 26, 2023, we issued 1,674 shares of our common stock with a per share value of $149.34, representing total compensation expense of $250,000.

Previous report

We signed a manufacturing agreement for clinical trial supply with regards to TH104 and the upcoming Phase 2 clinical trial on July 25, 2024 with a contract manufacturing organization located in North Carolina. The development work includes both TH104 active product and corresponding placebo batches expected to be released for clinical packaging by the end of the year.

Previous report

On September 30, 2024, we entered into a nonbinding, exclusive letter of intent (the “LOI”) with Intract pursuant to which we will acquire all outstanding shares of common stock of the privately-held Intract for newly issued restricted common stock. Intract is a biopharmaceutical company incorporated in England and Wales developing disruptive delivery solutions for oral biologics. Under the terms of the LOI, following the execution of a definitive agreement and the closing of the merger, Intract shareholders will own 49% of the total equity in the combined entity, which will be named Tharimmune, Inc., with Intract becoming a wholly owned subsidiary. We believe the merger and business combination will form a best-in-class, transformative oral biologics company and the synergies between our clinical-stage assets and Intract’s delivery platform will drive pipeline growth. During the three and nine months ended September 30, 2024, we paid a $75,000 exclusivity fee to enter into the LOI agreement.

Previous report

Three Months Ended September 30, 2024 Compared to the Three Months Ended September 30, 2023

Previous report

Interest income increased by $44,277, or 156%, to $72,728 for the three months ended September 30, 2024 from $28,451 for the three months ended September 30, 2023. The increase in interest income was primarily due to the increase in cash from the November 2023 Offering and the June 2024 PIPE Offering.

Previous report

Nine Months Ended September 30, 2024 Compared to the Nine Months Ended September 30, 2023

Previous report

Research and development expenses increased by $1.7 million, or 68%, to $4.3 million for the nine months ended September 30, 2024 from $2.6 million for nine months ended September 30, 2023. The increase was primarily the result of an increase in clinical trial expenses of approximately $0.9 million due to completion of our Phase 1 clinical trial in TH104 and an increase of $1.5 million in license fees. These increases were offset by a decrease of $0.5 million in pre-clinical expenses and a decrease of $0.1 million in stock-based compensation expense related to our research and development personnel.

Previous report

General and administrative expenses decreased by less than $0.1 million, or 2%, to $4.3 million for the nine months ended September 30, 2024 from $4.4 million for the nine months ended September 30, 2023. The change in general and administrative expenses was primarily due to a decrease of $0.4 million in investor relations, a decrease of $0.3 million in insurance, a decrease of $0.1 million in professional fees, and a decrease of $0.1 million in stock-based compensation expense related to our general and administrative personnel. These decreases were offset by an increase in wages of $0.7 million and an increase of $0.1 million in director remuneration.

Previous report

Interest expense decreased by $3,225, or 20%, to $12,926 for the nine months ended September 30, 2024 from $16,151 for the nine months ended September 30, 2023. The decrease in interest expense was primarily related to the decrease in D&O insurance premium financing liability.

Previous report

Interest income increased by $127,338, or 134%, to $222,236 for the nine months ended September 30, 2024 from $94,898 for nine months ended September 30, 2023. The increase in interest income was primarily due to the increase in cash from the November 2023 Offering and the June 2024 PIPE Offering.

Previous report

Cash provided by financing activities for the nine months ended September 30, 2023 was $2.1 million. The net increase in financing activities was from net cash proceeds of $2.3 million from the issuance of our common stock in connection with a public offering and $0.7 million in proceeds received from insurance premium financing liability offset by deferred offering costs of $0.3 million and $0.6 million in repayments of insurance premium financing liability.

Tharimmune is a clinical-stage biotechnology company developing therapeutic candidates in immunology and inflammation with high unmet need. On November 3, 2023, we entered into a patent license agreement (the “Avior License Agreement”) with Avior Inc. d/b/a Avior Bio, LLC (“Avior”) pursuant to which we received an exclusive sublicensable right and license to Licensed Patent Rights and Licensed Technology to, among other things, Develop, have Developed, make, have made, use, sell, import, export and commercialize TH104 and TH103 and to practice the Licensed Technology in connection with the foregoing, throughout the world, each as defined in the Avior License Agreement. In February 2023, the U.S. Food and Drug Administration (“FDA”) approved an investigational new drug (“IND”) application for TH104. TH104 has a dual mechanism of action by affecting multiple receptors, known to suppress chronic, debilitating pruritis or “uncontrollable itching.” With respect to TH104, we intend to first seek approval for the treatment of moderate-to-severe chronic pruritis in patients with primary biliary cholangitis (“PBC”), an orphan rare form of liver disease with no known cure in which more than 70% of patients suffer from debilitating chronic pruritic. The Company expects to obtain topline data in a Phase 2 trial with TH104 in Q4 2025 and with respect to TH103, we intend to develop the product candidate and potentially file an IND.

With respect to our PIND for this additional proposed indication for TH104, the Company received positive feedback from the FDA regarding a regulatory pathway that will allow the Company to submit a 505(b)(2) New Drug Application (“NDA”) for TH104. The FDA advised that we will need to perform additional nonclinical studies (*i.e.,*in vitro toxicology studies), but the FDA confirmed that it does not believe any additional clinical trials will be required to define the prophylactic dosing window prior to IND or NDA submission for this indication, which will be the lead program for the Company. The Company intends to pursue the pruritus in PBC indication subsequent to the nearer term opportunity of filing an NDA for PrHPO. The Company intends to conduct a capital efficient strategy to file an NDA for PrHPO, which involves actively progressing its Chemistry, Manufacturing, and Controls (“CMC”) plan to meet the stringent requirements for filing an NDA with the FDA. This comprehensive plan encompasses all aspects of the manufacturing process, quality control measures, and product stability to ensure the consistent productio…

We are also developing an early-stage pipeline of novel therapeutic candidates targeting validated high value immuno-oncology (“IO”) targets including human epidermal growth factor (“EGF”) receptor 2 (“HER2”), human EGF receptor 3 (“HER3”) and programmed cell death protein 1 (“PD-1”). We are developing antibodies including bispecific antibodies, antibody drug conjugates (“ADCs”) and small molecular weight bovine-derived Picobodies™ or antibody “knob” domains which have the potential to target and bind more tightly to “undruggable” epitopes better than full sized antibodies. We are advancing TH3215, a bispecific against both HER2 and HER3 antibody which targets a novel “bridging epitope” encompassing multiple domains of the HER2 extracellular domain (“ECD”) as well as ligand-dependent and independent blocking of the ECD of HER3 into IND-enabling studies in 2025. In addition, we anticipate that TH0059, a HER2/HER3 bispecific ADC (“bsADC”), and TH1940, a PD-1 Picobody, will progress to enter IND-enabling studies in 2025.
