Unmet need in bladder cancer

6th most common graphic

Four times more men are diagnosed with bladder cancer than women and the median age of diagnosis is 73 years old1. Bladder cancer is the 6th most common form of cancer in the US1. In 2022 there will be 81,190 new cases1.

75% of bladder cancer is non-muscle invasive bladder cancer graphic

75% of bladder cancer is non-muscle invasive bladder cancer (NMIBC) and 25% is classified as muscle invasive bladder cancer (MIBC)3.

50% highly recurrent graphic

Bladder cancer is a highly recurrent and progressive disease that is costly to the health care system because of the intense follow up schedule2,3.

Staging of Bladder Cancer:

Non-muscle invasive bladder cancer (NMIBC):

Patients with high-grade NMIBC, are treated with surgical removal of their lesions and intravesical treatment with BCG2. There is a great need for a local, well tolerated, and effective bladder preserving option for patients with intermediate risk as well as high risk BCG unresponsive NMIBC. In 70% of patients with BCG unresponsive disease, BCG fails to treat the disease. Two FDA approved therapeutic options are Valrubicin, which received approval in 1998, but reported low response rates and durability of response. Most recently in 2020, KEYTRUDA® a received approval it’s a systemic treatment; however, has not been widely adopted due to unfavorable toxicity. This leaves patients only treatment option being bladder removal (cystectomy). Cystectomy is associated with negative outcomes, mortality, and a reduced quality of life4,5,6,7. Ninety (90) days following discharge after cystectomy, 80% of patients have complications and 37% of those are major complications7. There is a 20%-30% readmissions rate within 30 days, a 3%-4% morbidity rate at 90 days following cystectomy. In fact, only 6% of eligible patients with BCG unresponsive disease undergo a cystectomy, with high-grade T1 disease4,5,6,7. Patients report preferring bladder preservation, and in many cases due to co-morbid conditions, are not eligible for such a demanding surgery3.

In Studies in patients with BCG unresponsive NMIBC:

Cretostimogene grenadenorepvec (CG0070) is being investigated in a global Phase 3 trial (BOND-003) as a monotherapy for the treatment of BCG-unresponsive, Non-Muscle Invasive Bladder Cancer (NMIBC). Most patients with high-risk NMIBC (CIS with or without Ta/T1, Ta or T1) who do not respond to BCG intravesical therapy (standard of care).

Cretostimogene grenadenorepvec (CG0070) is being further investigated in a clinical collaboration with Merck to evaluate the combination of cretostimogene grenadenorepvec (CG0070) with the anti-PD-1 therapy, KEYTRUDA® (pembrolizumab), in a Phase 2 clinical study (CORE-001) for the treatment of high risk, NMIBC in the BCG-unresponsive patient population.

Muscle Invasive Bladder Cancer (MIBC):

Approximately 20% of newly diagnosed bladder cancer cases are MIBC2. Up to 45% of high-risk NMIBC patients progress to MIBC within 5 years2,8. Annual cost of care is 70% higher for MIBC than yearly cost of care for NMIBC patients9. Delaying progression is significant because MIBC is associated with higher mortality. The 5-year mortality rates for T2, T3, and T4 patients are 56%,72%, and 91% respectively2,8. Cisplatin is the cornerstone of neoadjuvant chemotherapy, though up to 50% MIBC patients are cisplatin-ineligible due to decreased renal function, and neuropathy11. Checkpoint therapy has become the standard-of-care for patients who are cisplatin ineligible and have high PD-L1 expression11,12,13,14. Pathological Complete Response (pCR) rate is a surrogate for survival in MIBC patients treated with neoadjuvant therapy.

Combination trials for the treatment of MIBC:

  • Cretostimogene grenadenorepvec (CG0070) is also in a single-arm, multi-center trial Phase 1b study (CORE-002), to evaluate the safety and efficacy of the neo-adjuvant combination of cretostimogene grenadenorepvec (CG0070) plus OPDIVO® b (nivolumab) in patients with muscle-invasive bladder cancer (MIBC) who are ineligible for cisplatin-based chemotherapy. Primary endpoints of the trial will be safety and pathological complete response rate.

Unique Mechanism of Action

Cretostimogene grenadenorepvec (CG0070) was designed to work in two important and complementary ways. First, it replicates inside the tumor’s cells causing tumor cell lysis and immunogenic cell death. Then, the rupture of the cancer cells can release tumor-derived antigens, along with GM-CSF, that can stimulate a systemic anti-tumor immune response that involves the body’s own white blood cells.
