# Company Overview of Replimune Group, Inc.

## Business Focus
- Replimune is a **clinical-stage biotechnology company** specializing in **oncolytic immunotherapy** for cancer treatment.
- The company's goal is to **activate the immune system against cancer tumors** using proprietary engineered viruses.
- Their approach exploits viruses’ natural ability to selectively infect, replicate in, and lyse (kill) tumor cells.
- The platform, called **RPx**, is based on a **modified herpes simplex virus 1 (HSV-1)** backbone engineered to:
  - Replicate in tumor cells
  - Express immune-stimulating payloads, such as GM-CSF and fusogenic glycoproteins
  - Maximize immunogenic cell death and induce a systemic anti-tumor immune response
- The therapeutic design aims to be **"off-the-shelf"**, combining multiple mechanisms (direct tumor killing and immune activation) into a single, ready-to-use product.

## Product Pipeline & Development
- The company has **three main product candidates**:
  - **RP1 (Vusolimogene Oderparepvec)**: Lead candidate, in regulatory review for melanoma.
  - **RP2**: Engineered to express additional immune activators like anti-CTLA-4.
  - **RP3**: Designed to further stimulate immune response via ligands for CD40 and 4-1BBL.
- **Lead indication**:
  - RP1 targets **advanced melanoma**, currently under FDA biologics license application (BLA) review.
  - A focus on **skin cancers**, including cutaneous melanoma, basal cell carcinoma, SCC, Merkel cell carcinoma, and angiosarcoma.
- The company also programs RP1 for **solid organ transplant recipients** with skin cancers, in an ongoing trial.

## Clinical Trials & Partnerships
- Conducts **multiple clinical trials** for RP1, including monotherapy and combination with anti-PD-1 therapies.
- Collaborates with **Bristol Myers Squibb** (BMS) providing nivolumab (anti-PD-1) for trials.
- In 2024, submitted **Biologics License Application (BLA)** for RP1, granted **Breakthrough Therapy designation**, with a **PDUFA** date of July 22, 2025.
- Operating a **Phase 3 trial (I-3)** for melanoma patients who progressed on prior treatments.
- Conducts trials for **non-melanoma skin cancers** and **solid tumors** like liver and lung metastases.
- Also developing RP2 and RP3 against **other tumor types**, aiming to treat **metastatic uveal melanoma** and others.

## Employees & Financials
- **Number of employees**: 479 full-time employees (as of March 31, 2025).
  - 347 in research and development
  - 132 in sales, general, and administrative functions
- **Market capitalization**: Approximately **$523.2 million** (based on stock closing price on September 30, 2024).
- **Outstanding shares**: 77,086,750 as of May 19, 2025.
- **Revenue**: No revenue has been generated from product sales.
- **Net Loss for fiscal year**:
  - 2025: **$247.3 million**
  - 2024: **$215.8 million**
- **Accumulated deficit**: **$948.6 million** as of March 31, 2025.

## Business Strategy
- Focused on **advancing oncolytic immunotherapy** via the **RPx platform**.
- Developing **multiple product candidates** for various tumor types.
- Collaborating with major pharmaceutical companies for development, supply, and potential commercialization (e.g., BMS, Roche, Regeneron).
- Operating its own manufacturing facility in Massachusetts to secure supply chain and control production.

*Note: The company has yet to generate revenue from commercialized products and remains focused on R&D, clinical trials, and regulatory approval processes.*

The company is a clinical-stage biotechnology firm specializing in oncolytic immunotherapy using engineered strains of herpes simplex virus to target and destroy cancer cells.

# Company Overview

## Business Focus
The company is a clinical-stage biotechnology firm specializing in **oncolytic immunotherapy** aimed at transforming cancer treatment. Its proprietary therapies use engineered strains of **herpes simplex virus (HSV-1)** to selectively target and destroy cancer cells while enhancing the body’s immune response against tumors. The company aims to establish oncolytic immunotherapy as a cornerstone of cancer treatment, alongside checkpoint blockade therapies.

### Product Platform
- **RPx Platform**: A proprietary platform based on a novel strain of HSV-1 that incorporates multiple mechanisms for activating the immune system.
- **Key Product Candidates**:
  - **RP1 (vusolimogene oderparepvec)**: The lead candidate undergoing clinical trials primarily for melanoma and other skin cancers.
  - **RP2** and **RP3**: Additional candidates engineered to enhance anti-tumor immune responses and target other cancers.

## Clinical Activities
- **Clinical Trials**: The company is conducting various clinical trials, including:
  - **IGNYTE Trial**: A multi-cohort Phase 1/2 trial investigating RP1 in combination with nivolumab (an anti-PD-1 therapy) for melanoma patients who have not responded to prior treatments.
    - Reported an overall response rate (ORR) of **31.4%** and a complete response rate (CRR) of **12%** for 156 patients.
  - **ARTACUS Trial**: A Phase 1b/2 clinical trial for solid organ transplant recipients with skin cancers.
  - **CERPASS Trial**: A controlled Phase 2 trial of RP1 combined with cemiplimab for cutaneous squamous cell carcinoma (CSCC).

## Workforce and Financials
- **Employees**: As of March 31, 2024, the company employs **331 individuals**, with the majority dedicated to research and development (280 employees).
- **Revenue and Loss**: The company has reported financial losses, with a net loss of **$215.8 million** for the year ended March 31, 2024, and an accumulated deficit of **$701.3 million**.

## Collaboration and Manufacturing
