Previous wording

We are a biopharmaceutical company focused on discovering and developing potential best-in-class medicines for serious and rare diseases. We target disease areas where marketed therapies often leave room for improvements in efficacy, safety, and/or dosing convenience. We believe that first-generation medicines rarely represent optimal solutions, especially in rare disease areas, and that there is potential to develop differentiated, best-in-class medicines that could lead to improved patient outcomes, reduced side effects, improved quality of life, expanded market access, and augmented market competition. Our business model is designed to identify and evaluate product opportunities in disease areas where trial data establishes proof-of-concept for a drug target in the clinic, but the competitive evolution of the product life cycle management and number of entrants appears incomplete. We intend to prioritize indications where a fast-follower and a potentially differentiated drug candidate, or overall product profile, could create significant medical benefit for patients. We are engineering medicines to address unmet medical needs for patients and further advance drug innovation.

Previous wording

We are developing two product candidates, VRDN-001 for intravenous and VRDN-003 for subcutaneous administration, to treat patients who suffer from TED. Our most advanced program, VRDN-001, is a differentiated humanized monoclonal antibody targeting IGF-1R intravenously administered for the treatment of TED. In previously presentedin vitro preclinical data, we showed that VRDN-001 is a potentially differentiated full antagonist of IGF-1R, compared to teprotumumab’s incomplete antagonism of IGF-1R. We also conducted phase 1/2 clinical trials of VRDN-001 in patients with active or chronic TED. In the active TED portion of the phase 1/2 clinical trials, data reported from all three dose cohorts of VRDN-001 (n=21) showed significant and rapid improvement in both the signs and symptoms of TED after two infusions of VRDN-001 compared to placebo. Across all VRDN-001 treated patients in the active TED trial, 71% were proptosis responders, 67% were overall responders, 62% achieved a CAS of 0 or 1, and 54% had complete resolution of their diplopia. In the chronic TED portion of the phase 1/2 clinical trials, data reported from both dose cohorts of VRDN-001 (n=12) showed significant and rapid improvement in the signs and symptoms of TED after two infusions of VRDN-001 compared to placebo. Across all VRDN-001 treated patients in the chronic TED trial, 42% were proptosis responders, 40% achieved a CAS of 0 or 1, and no patients had complete resolution of their diplopia. In the phase 1/2 clinical trials of both active and chronic TED, VRDN-001 had a favorable safety profile and was well-tolerated by all patients treated in all dose cohorts.

Current wording

We are developing two product candidates, veligrotug (formerly known as VRDN-001) for intravenous and VRDN-003 for subcutaneous administration, to treat patients who suffer from TED. Our most advanced program, veligrotug, is a differentiated humanized monoclonal antibody targeting IGF-1R intravenously administered for the treatment of TED. In previously presentedin vitro preclinical data, we showed that veligrotug is a potentially differentiated full antagonist of IGF-1R, compared to teprotumumab’s incomplete antagonism of IGF-1R. We also conducted phase 1/2 clinical trials of veligrotug in patients with active or chronic TED.

Previous wording

We are conducting a global pivotal program for VRDN-001, including evaluating its efficacy and safety in two global well-controlled phase 3 clinical trials, THRIVE and THRIVE-2, for the treatment of active and chronic TED, respectively. THRIVE and THRIVE-2 are each designed to compare a five-dose IV treatment arm of VRDN-001 at 10 mg/kg, dosed three weeks apart, to placebo. This five-dose VRDN-001 regimen features fewer infusions and a shorter time per infusion compared to teprotumumab, the currently marketed IGF-1R inhibitor. We expect to report topline THRIVE and THRIVE-2 data in September 2024 and by year end 2024, respectively. In addition, to meet the 300 patient standard safety database requirements for the VRDN-001 BLA, we are actively enrolling patients into our STRIVE clinical trial. STRIVE is a global study of VRDN-001 in TED patients that utilizes broad inclusion criteria (e.g., any severity or duration of disease) and is randomized 3:1 (10 mg/kg IV with an active control of 3 mg/kg IV). We are also enrolling patients in the open label extension study for non-responding patients in THRIVE and THRIVE-2. We anticipate filing a BLA for VRDN-001 in the second half of 2025.

Current wording

We are conducting a global pivotal program for veligrotug, including evaluating its efficacy and safety in two global well-controlled phase 3 clinical trials, THRIVE and THRIVE-2, for the treatment of active and chronic TED, respectively. On September 10, 2024, we announced topline data from the THRIVE study, which enrolled 113 patients, randomized to veligrotug (n=75) and placebo (n=38). THRIVE achieved all primary and secondary endpoints with a high level of statistical significance (p < 0.0001) and was generally well-tolerated, with no treatment-related SAEs. Veligrotug additionally showed a rapid onset of action, with the majority (53%) of veligrotug-treated patients achieving a proptosis response after just one infusion, or three weeks after start of therapy. We completed enrollment of THRIVE-2 in July 2024, and expect to announce topline data for this study by the end of 2024. THRIVE and THRIVE-2 are each designed to compare a five-dose IV treatment arm of veligrotug at 10 mg/kg, dosed three weeks apart, to placebo. This five-dose veligrotug regimen features fewer infusions and a shorter time per infusion compared to teprotumumab, the currently marketed IGF-1R inhibitor. In addition, to meet the 300 patient standard safety database requirements for the veligrotug biologics license application (“BLA”), we are actively enrolling patients into our STRIVE clinical trial. STRIVE is a global study of veligrotug in TED patients that utilizes broad inclusion criteria (e.g., any severity or duration of disease) and is randomized 3:1 (10 mg/kg IV with an active control of 3 mg/kg IV). We are also enrolling patients in the open label extension study for non-responding patients in THRIVE and THRIVE-2. We anticipate filing a BLA for veligrotug in the second half of 2025.

Previous wording

In addition to our VRDN-001 IV program, in December 2023 we selected VRDN-003 as our subcutaneous product candidate for pivotal development in TED following positive data in a phase 1 clinical trial in healthy volunteers. We believe VRDN-003 has the potential to be the best-in-class subcutaneous anti-IGF-1R product candidate by preserving the efficacy of anti-IGF-1Rs in TED, improving safety, and maximizing convenience for patients. VRDN-003 has the same binding domain as, VRDN-001, and was engineered to have a longer half-life. VRDN-003 is designed to be a low-volume, self-administered, infrequently dosed subcutaneous IGF-1R for TED, which we plan to launch commercially with an auto-injector.

Previous wording

The VRDN-003 phase 1 clinical study showed VRDN-003 to have a prolonged half-life of 40 to 50 days, which is four to five times that of VRDN-001. Because of the healthy volunteer data and the similarities between the VRDN-001 and VRDN-003 antibodies, we expect VRDN-003 to have similar clinical responses at the exposure levels of VRDN-001 that led to robust clinical activity in its phase 2 clinical trial in TED. Further, pharmacokinetic modeling of VRDN-003 based on the healthy volunteer data predicted that exposure levels of VRDN-003 could be achieved that are equivalent to exposure levels of VRDN-001 that produced clinically meaningful results with multiple dosing regimens of VRDN-003, i.e., subcutaneous injection every two, four, or eight weeks. We are advancing our VRDN-003 program, including initiating two planned global phase 3 clinical trials, REVEAL-1 and REVEAL-2, to evaluate the efficacy and safety of VRDN-003 in patients with active and chronic TED. We also anticipate that the program will include a safety study to complete a 300 patient standard safety database (to include patients from the REVEAL-1 and REVEAL-2 trials), and we expect that it will also include the required development to have an auto-injector device available at the time of commercial launch, if approved. We anticipate topline data for REVEAL-1 and REVEAL-2 in the first half of 2026, and we anticipate submitting a BLA for VRDN-003 by the end of 2026.

We are advancing our VRDN-003 program, including the initiation of two global phase 3 clinical trials for VRDN-003 in August 2024: REVEAL-1 and REVEAL-2 in active and chronic TED, respectively. Both studies will evaluate subcutaneous VRDN-003 administered every four weeks or every eight weeks and will assess outcomes versus placebo. We also anticipate that the program will include a safety study to complete a 300 patient standard safety database (to include patients from the REVEAL-1 and REVEAL-2 trials), and we expect that it will also include the required development to have an auto-injector device available at the time of commercial launch, if approved.

VRDN-006 is a FcRn-targeting Fc fragment, and in non-human primate studies, demonstrated specificity for blocking FcRn-IgG interactions while not showing decreases in albumin or increases in LDL levels, which are known potential side effects associated with certain full-length anti-FcRn monoclonal antibodies. In our head-to-head non-human primate studies, VRDN-006 demonstrated comparable potency and IgG reductions to Vyvgart® (efgartigimod), the current standard of care in FcRn inhibition, as well as a similar safety profile. We plan to file an IND for VRDN-006 by the end of 2024 and expect healthy volunteer data for VRDN-006 in the second half of 2025. VRDN-008 is a novel, potential first-in-class FcRn inhibitor that aims to pair IgG suppression with extended half-life technology, potentially enabling deeper and more durable suppression of IgG than existing anti-FcRn therapies. Both molecules are designed to be convenient, self-administered, subcutaneous products.

Per the terms of the Hercules Loan and Security Agreement, we were originally obligated to make interest-only payments through April 1, 2024.

If additional development milestones were met, the interest-only period would be further extended to April 1, 2025 pursuant to a second extension. We were required to repay the Term Loan amount in equal monthly installments of the principal amount and interest between the end of the interest-only period and the maturity date of October 1, 2026.
