Previous wording

Our proprietary RPx platform is based on a novel, engineered strain of herpes simplex virus 1, or HSV-1, backbone with payloads added to maximize immunogenic cell death and the induction of a systemic anti-tumor immune response. The RPx platform is intended to have unique dual local and systemic activity consisting of direct selective virus-mediated killing of the tumor resulting in the release of tumor-derived antigens and altering of the tumor microenvironment to ignite a strong and durable systemic response. Our product candidates are expected to be synergistic with most established and experimental cancer treatment modalities, and, with an attractive safety profile the RPx platform is expected to have the versatility to be developed alone or combined with a variety of other treatment options. We currently have three RPx product candidates in our development pipeline, RP1 (vusolimogene oderparepvec), our lead product candidate, RP2 and RP3. Although our fiscal year ends March 31 st, our programs and program updates are reported on a calendar year basis.

We are conducting a number of clinical trials of RP1, both as a monotherapy and in combination with anti-PD-1 therapy, with a focus on establishing a major skin cancer franchise.

Current wording

We are conducting a number of clinical trials of RP1, both as a monotherapy and in combination with anti-PD-1 therapy, with a focus on establishing a major skin cancer franchise, assuming approval of our product candidates by the U.S. Food and Drug Administration, or the FDA, and similar applicable foreign regulatory agencies.

Previous wording

Our leading clinical trial of RP1 is our IGNYTE trial, a multi-cohort clinical trial being conducted in collaboration with Bristol Myers Squibb Company, or BMS, under which BMS has granted us a non-exclusive, royalty-free license to, and is supplying at no cost, its anti-PD-1 therapy, nivolumab, for use in combination with RP1. The leading tumor specific cohort in the IGNYTE trial is our registration directed Phase 2 expansion cohort in anti-PD-1 failed cutaneous melanoma. The anti-PD1 failed melanoma cohort from the IGNYTE clinical trial includes 140 patients who received RP1 plus nivolumab. The primary analysis by independent central review was triggered once all patients had been followed for at least 12 months. The topline results showed the overall response rate, or ORR, was 33.6% by modified RECIST 1.1 criteria, the primary endpoint as defined in the protocol, and 32.9% by RECIST 1.1 criteria, an additional analysis requested by the U.S. Food and Drug Administration, or FDA. Responses from baseline were highly durable with 85% of responses lasting more than 12 months. The median duration of response from baseline was 27.6 months and the median duration of response from treatment initiation was 21.6 months. RP1 combined with nivolumab continues to be well-tolerated, with mainly Grade 1-2 “on target” side effects, observed. In September 2024, we presented the independently reviewed data from the IGNYTE clinical trial, including key secondary endpoints and subgroup analyses as a late-breaking abstract during an oral session at the European Society for Medical Oncology, or ESMO. Data presented at ESMO showed activity across all subgroups, including patients who had prior anti-PD1 and anti-CTLA-4 treatment had an ORR of 27.7% and patients who had primary resistance to anti-PD1 had an ORR of 35.9% by modified RECIST v1.1. In November 2024, we announced submission of a biologics license application (BLA) to the FDA for RP1 (vusolimogene oderparepvec) in combination with nivolumab for the treatment of adult patients with advanced melanoma who have previously received an anti-PD1 containing regimen and that the FDA has granted Breakthrough Therapy designation to RP1 in combination with nivolumab in the same setting. The submission was made under the Accelerated Approval pathway. We recently announced the FDA accepted our BLA and granted priority review with a Prescription Drug User Fee Act goal date of July 22, 2025.

Current wording

Our leading clinical trial of RP1 is referred to as the IGNYTE trial, which is a multi-cohort clinical trial being conducted in collaboration with Bristol Myers Squibb Company, or BMS, under which BMS has granted us a non-exclusive, royalty-free license to, and is supplying at no cost, its anti-PD-1 therapy, nivolumab, for use in combination with RP1.

Previous wording

Following a Type C meeting with the FDA, a confirmatory study design concept consisting of a 2-arm randomized trial with physician’s choice of treatment as a comparator arm in anti-PD1 failed melanoma patients, or the IGNYTE-3 trial, was agreed. The FDA requested that the Phase 3 confirmatory IGNYTE-3 trial be underway at the time of a BLA submission under the accelerated approval pathway. In August 2024, we announced the dosing of the first patient in our IGNYTE-3 trial and enrollment in the IGNYTE-3 trial continues. This trial is planned to have over 100 sites globally and will assess RP1 in combination with nivolumab in patients with advanced melanoma who have progressed on anti-PD-1 and anti-CTLA-4 therapies or are ineligible for anti-CTLA-4 treatment.

Current wording

In August 2024, we announced the dosing of the first patient in the IGNYTE-3 trial, or the I-3 trial, a confirmatory study design concept consisting of a 2-arm randomized Phase 3 clinical trial with physician's choice of treatment as a comparator arm in anti-PD-1 failed melanoma patients. With over 100 sites planned globally and an expectation to enroll 400 patients, the I-3 trial will assess RP1 in combination with nivolumab in patients with advanced melanoma who have progressed on anti-PD-1 and anti-CTLA-4 therapies or are ineligible for anti-CTLA-4 treatment. We continue to enroll patients in the I-3 trial.

Previous wording

In our non-melanoma skin cancer, or NMSC, cohort of the IGNYTE clinical trial, we provided a data update in December 2023 from the first 30 patients with at least 6 months of follow up including patients with cutaneous squamous cell carcinoma, or CSCC, Merkel cell carcinoma, or MCC, basal cell carcinoma, and angiosarcoma in this cohort. The data showed that treatment with RP1 in combination with nivolumab led to an ORR of 30% which is consistent with data from the anti-PD1 failed melanoma cohort with approximately one-third of patients responding and 60% demonstrating clinical benefit. The combination of RP1 and nivolumab was well tolerated in this patient population with a safety profile consistent with the overall experience seen with this treatment regimen to date. Enrollment remains open in this cohort.

Furthering development of our RP1 clinical candidate, we have open for enrollment a Phase 1b/2 clinical trial of single agent RP1 in solid organ transplant recipients with skin cancers, including CSCC, which is referred to herein as ARTACUS or the ARTACUS trial, which we believe to be potentially registrational (in its own right or, subject to discussion with regulatory authorities, following enrollment of additional patients, including as a potential label expansion after an initial approval of RP1 in a different indication). We are currently enrolling up to 65 patients in the ARTACUS trial to assess the safety and efficacy of RP1 in liver, kidney, heart, lung, and hematopoietic cell transplant recipients with skin cancers. In November 2023 we presented initial data from the ARTACUS clinical trial of RP1 monotherapy in solid organ transplant recipients with skin cancers at the Society for Immunotherapy of Cancer’s (SITC) 38th Annual Meeting. The data included 23 evaluable patients with CSCC (n=20) and Merkel cell carcinoma (n=3), demonstrating an overall response rate, or ORR of 34.5% and a complete response, or CR of 21%. RP1 monotherapy was well tolerated in these patients and the safety profile was similar to that observed in our other RP1 clinical trials in patients who are not immune suppressed. No immune-mediated adverse events or evidence of allograft rejection were observed. This data was also presented during oral presentation at the American Association of Cancer Research 2024 Annual Meeting in April 2024. We continue to enroll patients into this trial.

We are also developing or have been developing additional product candidates, RP2 and RP3, that have been further engineered to enhance anti-tumor immune responses and are intended to address additional tumor types, including traditionally less immune responsive tumor types. In addition to the expression of GALV-GP R(-) and human GM-CSF as in RP1, RP2 has been engineered to express an antibody-like molecule intended to block the activity of CTLA-4, a protein that inhibits the full activation of an immune response, including to tumors. RP3 has been engineered with the intent to further stimulate an anti-tumor immune response through activation of immune co-stimulatory pathways through the additional expression of the ligands for CD40 and 4-1BBL, as well as anti-CTLA-4 and GALV-GP R(-), but without the expression of GM-CSF.

We continue the development of our clinical candidate RP2 with a focus on establishing a rare cancer franchise. Notably, as previously reported, from our Phase-1 clinical trial of RP2 alone and in combination with nivolumab, we have seen durable responses from a monotherapy cohort in a variety of difficult to treat tumors as well as in combination with anti-PD1 and in particular in patients with metastatic uveal melanoma (MUM). In November 2023, we presented updated data from a cohort of MUM patients during a Plenary Session at the 20th Annual International Society for Melanoma Research Congress. The updated data showed RP2 led to an ORR of 29.4% (5 of 17 patients; one of the responding patients was treated with RP2 monotherapy and four of the responding patients were treated with RP2 combined with nivolumab), including responses in patients with liver, lung, and bone metastases. The median DOR at the data cutoff was 11.47 months (range of 2.78 to 21.22 with responses ongoing). Nearly all patients (15 of 17, or 88.2%) in the study had progressed on or after immunotherapy with 12 of 17 patients (70.6%) having previously received both anti-PD1 and anti-CTLA-4 therapies, including four of the responding patients. RP2 was generally well tolerated both as monotherapy and in combination with nivolumab with no additive adverse events observed. The most common grade 1 or 2 treatment related adverse events, or TRAEs, overall in both cohorts were pyrexia, chills, fatigue, hypotension and pruritis. Six patients had grade 3 TRAEs, including two cases of hypotension. There were no grade 4 or 5 TRAEs. In June 2024, we presented that the disease control rate for this cohort of MUM patients was 58.8%. We have initiated and are enrolling patients in a registration-directed study of RP2 in MUM patients who are immune checkpoints inhibitor-naïve. The study is a randomized trial of RP2 in combination with nivolumab vs. ipilimumab and nivolumab, or nivolumab for those ineligible for ipilimumab.

Previous wording

The overall increase of $5.2 million in total research and development expenses was driven by an increase of approximately $6.7 million in our unallocated expenses which is driven by a $3.7 million increase in personnel related costs, as well as a $3.0 million increase in other costs primarily attributable to increased consultants and facility costs.

Current wording

The overall increase of $14.9 million in total research and development expenses was driven by an increase of approximately $9.6 million in our unallocated expenses which is comprised of a $5.5 million increase in personnel related costs, as well as a $4.1 million increase in other costs primarily attributable to increased medical affairs and consulting costs.

Previous wording

Selling, general and administrative expenses were $18.0 million for the three months ended December 31, 2024, compared to $13.7 million for the three months ended December 31, 2023. The increase of $4.3 million is primarily the result of an increase of $3.0 million in sales and marketing costs as the Company prepares for its first potential commercial launch of RP1. In addition, there is an increase of $1.7 million in personnel related costs, including an increase of $2.1 million in payroll and fringe benefits, slightly offset by a $0.4 million decrease in stock-based compensation expense. The increase in personnel related costs during the quarter was driven by additional hiring in our selling, general and administrative functions, focusing on additional pre-launch planning and continued building of the Company's commercial infrastructure. Consulting costs during the quarter are down year over year by approximately $1.4 million in selling, general and administrative functions as a result of hiring more full time employees in the current year.

Current wording

Selling, general and administrative expenses were $32.6 million for the three months ended June 30, 2025, compared to $14.4 million for the three months ended June 30, 2024.

Other income (expense), net was $0.3 million for the three months ended December 31, 2024, compared to income of $5.9 million for the three months ended December 31, 2023. The net change of $5.6 million is primarily attributable to an increase in expense of $4.6 million in the current quarter compared to the prior year due to exchange rate fluctuations related to the changes in foreign exchange rates of the British Pound Sterling to the United States Dollar, specifically on intercompany and other non-functional currency transactions. In addition, investment income decreased by approximately $0.5 million year over year and the interest expense on debt obligations increased by approximately $0.4 million, as the Company drew down an additional $15.0 million under the Loan Agreement at the end of December 2023.

Current wording

Other income (expense), net was $3.7 million for the three months ended June 30, 2025, compared to income of $3.6 million for the three months ended June 30, 2024. Total other income (expense), net is relatively consistent year over year, with a net change of $0.1 million. The change is primarily attributable to a decrease in expense of $0.2 million in the current quarter compared to the prior year due to exchange rate fluctuations related to the changes in foreign exchange rates of the British Pound Sterling to the United States Dollar, specifically on intercompany and other non-functional currency transactions. This was somewhat offset by an increase in interest expense on debt obligations.

Current wording

In December 2022, we entered into a Master Clinical Trial Collaboration and Supply Agreement with Roche in relation to our RP2 and RP3 programs in colorectal cancer, or CRC, and HCC. Under the agreement, the companies intended to collaborate in 30 patient cohort signal finding studies in third-line, or 3L, CRC and in first- and second-line, or 1L and 2L, respectively, HCC. Following our re-prioritization of our product development portfolio in December 2023, we have agreed with Roche to terminate the CRC collaboration and pursue the 2L cohort in HCC with RP2 only. Roche has continued to supply its currently approved drugs, atezolizumab and bevacizumab for the 2L cohort in HCC but is not sharing costs following our re-prioritization. Under the terms of the initial agreement we retained the responsibility of operating the clinical trials as well as retaining all the rights to the development and commercialization of our product candidates. The agreement may be terminated by either party upon sixty days prior written notice to the other party.
