Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The RUTIVAC-1 study is a Phase I Clinical Trial designed to evaluate the systemic and mucosal immunological response and provide safety information after the use of RUTI® administration to individuals with NMIBC.

The study will enroll individuals treated with Transurethral resection of bladder tumor (TURBT), diagnosed to have high-risk Non-muscle invasive bladder cancer (NMIBC) and suitable candidates for BCG therapy and who meet all eligibility criteria.

Forty individuals will be recruited and randomized 1:1 to receive two subcutaneous shots of 25 μg RUTI® or placebo. After vaccination, individuals will receive the standard induction course, of intravesical Bacillus Calmette-Guerin (BCG)therapy (weekly BCG for six weeks).

4 to 8 weeks after the last intravesical BCG administration (BCG6) a visit will be performed (Visit 1, end of the interventional phase). Once all participants have performed VISIT 1 immunological assays will be performed and data will be analyzed.

At the end of the Interventional Phase the blind will be opened, except for the study physicians who will remain blind during all the follow-up. All the individuals will be followed up for three years since TURBT.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

2. Age ≥18 years.
3. General health status according to WHO ≤ 2.
4. Have primary histologically confirmed T1 and/or high grade tumors and/or CIS.
5. All visible papillary tumors must be completely resected.
6. Early postoperative (within 24 hours of TURBT) single dose chemotherapy is allowed.
7. BCG therapy indication.
8. Never treated with BCG immunotherapy
9. Willing to comply with study visits and procedures as per protocol
10. Use of reliable contraception (see section 8.6) from the screening visit to 30 days after the last RUTI® or placebo injection.

Exclusion Criteria

1. Life expectancy \<5 years.
2. Have a severe concomitant disease that might limit compliance or completion of the protocol.

4. Have other neoplasms.
5. Have congenital or acquired immune deficiencies or under immunomodulatory treatment.
6. Be receiving cytotoxic drugs or systemic corticosteroids within 8 weeks of receiving the first administration of BCG.
7. Have received radiation therapy for their bladder cancer within 4 months prior to study entry.
8. Have active infections (including urinary tract infections) defined as viral, bacterial, or fungal infections requiring therapy, HIV-positive status, concurrent febrile illness, gross hematuria or other factor that could influence tolerability to intravesical BCG therapy.
