Pipeline

Overview

Lead programme in non-muscle invasive bladder cancer (NMIBC).

HSV5-15 is being developed initially for NMIBC - a multi-billion-dollar market with significant unmet need - with active discovery programmes in prostate, breast, and sarcoma.

Lead indication

Non-muscle invasive bladder cancer.

Common, recurrent, and expensive to manage - with few treatment options for high-risk patients.

The patient journey today

From symptoms to ongoing treatment - and recurrence.

The current standard of care is BCG (Bacillus Calmette-Guérin) immunotherapy. It works for many - but it is toxic, and not all patients respond.

  1. Step 1

    Symptoms

    Patient presents to primary care with haematuria, urinary frequency, or pelvic pain.

  2. Step 2

    Testing

    Work-up includes cystoscopy, urine cytology, and imaging (CT, MRI). Risk stratified.

  3. Step 3

    Surgical procedure

    Transurethral resection of bladder tumour (TURBT), followed by staging and grading.

  4. Step 4

    Ongoing treatment

    Intravesical BCG, perioperative chemo, or escalation (cystectomy, pembrolizumab, nadofaragene).

Unmet need

BCG isn't enough. Many patients recur - and CIS predicts the worst.

Carcinoma in situ (CIS) is a localised, high-grade, aggressive form of early bladder cancer - and the hallmark of progressive, invasive disease. Most existing treatments fail to eliminate it.

Recurrence is the rule, not the exception

Intermediate- and high-risk groups recur frequently - often within a year of treatment.

BCG: effective for some, toxic for most

Current standard of care has limited utility and high toxicity - most patients unable to complete the full course and maintenance of BCG.

CIS resists most treatments

Resolving CIS is critical to successful long-term treatment - yet most therapies fail to eliminate it.

Our solution

HSV5-15 - designed for the unique biology of NMIBC.

Intravesical HSV5-15 viral therapy destroys residual tumour and eliminates CIS, while inducing anti-tumour immunity in the bladder lining to protect against future recurrence.
