Replimune Provides 2020 Year End Review and Overview of Expected 2021 Milestones
Commercial-scale facility operational; GMP manufacturing underway
“Replimune made great progress in 2020 providing positive data read outs in multiple tumor types which support our registration-directed programs with
Program Highlights and Upcoming Milestones
RP1in combination with Libtayo® in CSCC: The Company is actively enrolling patients into its global registration-directed Phase 2, randomized, controlled, clinical trial. The Company remains on track to provide the primary data read out in 2022. RP1in combination with Opdivo® in anti-PD-1 failed melanoma: The Company initiated recruitment into a new registration-directed 125-patient cohort Phase 2 clinical trial of RP1in combination with Opdivo in the first half of 2020 and continues to enroll patients. The Company remains on track to provide the primary data readout in 2022. RP1in combination with Opdivo in melanoma and non-melanoma skin cancers (NMSC): In October 2020, Replimuneprovided positive Phase 2 data updates in melanoma and NMSC which demonstrated deep and durable responses to RP1combined with Opdivo, including in anti-PD1 failed melanoma that continues to support the Company’s ongoing registration-directed development in this setting and in CSCC. Enrollment of the initial melanoma cohort (including anti-PD1 naïve and anti-PD1 failed patients) was completed in the first half of 2020 with the NMSC cohort now being expanded from 30 to 45 patients to also include 15 patients with anti-PD1 failed disease. RP1in anti-PD1 failed NSCLC: The Company has expanded the clinical study of RP1combined with Opdivo to include a new cohort of 30 anti-PD1 failed NSCLC patients and plans to dose its first patient in early 2021. RP1as monotherapy in solid organ transplant recipients with CSCC: The Company is currently enrolling a 30 patient Phase 1b clinical trial assessing the safety and efficacy of RP1in liver and kidney transplant recipients. The Company expects to dose its first patient in early 2021. Progress on this study has been particularly impacted by COVID-19 due to the immune suppression that solid organ transplant patients receive. Initial data from this clinical trial is intended to be presented in the second half of 2021. RP1in combination with Opdivo in MSI-H/dMMR tumors: The Company is accumulating data from the MSI-H/dMMR (anti-PD1 naïve) cohort. Based on the data, the Company expects to decide whether to pursue MSI-H/dMMR tumors into registration-directed development in 2021. RP2alone and in combination with Opdivo: RP2is an enhanced potency oncolytic immunotherapy which expresses an anti-CTLA-4 molecule, intended to improve on the safety and efficacy profile of systemic antibody approaches to targeting CTLA-4, in addition to expressing the GALV-GP R- fusogenic protein and GM-CSF. RP2is being evaluated in a Phase 1 clinical trial alone and combined with Opdivo in advanced solid tumor patients. In October 2020, Replimunepresented positive data from the single agent RP2portion of the clinical trial that showed deep and durable responses, including in patients with immune insensitive tumor types. Following the monotherapy phase, enrollment is currently underway in a 30-patient cohort in combination with Opdivo. Updated data from this clinical trial is expected to be presented mid-year. RP3alone and in combination with anti-PD-1 therapy: Replimuneinitiated dosing in its Phase 1 clinical trial of RP3in December 2020. RP3is the Company’s third product candidate, which in addition to GALV-GP R- and anti-CTLA-4 also expresses CD40L and 4-1BBL. The Phase 1 clinical trial is designed to evaluate RP3alone and combined with anti-PD1 therapy in advanced solid tumor patients. Initial data is expected to be presented in the second half of 2021.
- Targeted evaluation for new indications is currently underway: An analysis of the solid tumor space is currently underway to define the later stage and registrational clinical development pathway initially intended for
RP2and/or RP3. This is from the perspective that RP2and RP3are intended to target less immune responsive tumor types, and follows from initial promising data having been generated with single agent RP2, including in immune non-responsive tumor types. The details of this initial development plan are intended to be announced mid-year.
- Manufacturing: The Company has completed buildout of its 63,000-square-foot state-of-the-art manufacturing facility in
Framingham, MAto support late-stage development and full commercialization of all of its products. GMP production is underway.
- Potential impact of COVID-19 on milestones: Enrollment into the Company’s clinical trials, in particular the clinical trial of
RP1in solid organ transplant patients with CSCC which represents a highly immune compromised patient population, has been slower than expected, which the Company attributes to the global pandemic. While mitigation plans have been implemented, as the clinical trial sites continue to evaluate their capacity to enroll patients into clinical trials, the Company could see additional impact on the pace of enrollment across its clinical trial programs.
- Cash Position: Based on its current operating plan,
Replimuneexpects that its preliminary cash, cash equivalents and short-term investments of $493 millionas of December 31, 2020is expected to fund its operating expenses and capital expenditure requirements into the second half of 2024.
