Study summary

Phase I study, single site, open label with dose escalation, for evaluate safety and the oncolitic Adenovirus VCN-01 activity in patients with refractory retinoblastoma.

Read the detailed description

Phase I clinical trial, single-center, open-label, dose-escalation study, to evaluate the safety of the VCN-01 and, secondarily, its anti-tumoral activity. The trial sample consists of approximately 13 patients aged between 1 and 12 years old.

Inclusion criteria

  1. Patients with retinoblastoma with a somatic mutation of the geneRB1 and active tumor in a single eye, or germinal mutation of RB1 with active tumor/s in an eye and the contralateral eye unaffected, enucleated or without tumor activity. In both cases, with the use of systemic, intraarterial or intravitreal chemotherapy or radiotherapy, in accordance with the availability at his/her referral site, in whom enucleation is the only recommended treatment under opinion of the medical team treating the case at the originating referral site.
  2. Normal renal function: serum creatinine: \<45μmol/L (0-2 years); \<57μmol/L (3-6 years); \<60μmol/L (7-10 years); \<80μmol/L (11-13 years).
  3. Normal Hepatic function: serum : \<0,52μkat/L (de 9 months -12 years); serum AST: 61-80 g/L (8 months - 5 years); 63-83 g/L (5-9 years); 63-82 g/L (9-12 years).
  4. Adequate marrow reserve manifested in an > 1000 / mm3, > 100,000 / mm3 and > 8 g / dl, without transfusional or cytokine support at least one month prior to study entry.
  5. Age greater than one year and less than 12 years at the time of inclusion in the study.
  6. form signed.

Exclusion criteria

Exclusion Criteria:

  1. Presence of factors that require immediate enucleation of the affected eye such as glaucoma, rubeosis iridis, anterior chamber involvement.
  2. Comorbidities: Uncontrolled epilepsy with anticonvulsant treatment, cardiac disease not compensated by treatment.
  3. Active Infections.
  4. Other chronic or active acute diseases that under the criterion of the researcher were an exclusion criterion.
  5. History of having received attenuated or in the 30 days prior to inclusion in the study.
  6. Any cause of .
  7. Trilateral Retinoblastoma.
  8. Extraocular spread.
  9. History of having received treatment for retinoblastoma with chemotherapy or radiation therapy by any means within 30 days prior to inclusion in the study.
  10. Patients who can not complete the study procedures for reasons psychological or social.
  11. Pregnancy. Female patients with procreative potential should be agree to undergo a blood or urine pregnancy test and the result should be negative to enter the study.
Terms in these criteria, in plain language(8)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Relapsed and refractory

Relapsed: the illness came back after treatment had worked. Refractory: it did not respond to treatment, or stopped responding while still on it.

ALT and AST (liver enzymes)

Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.

Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.

Absolute neutrophil count (ANC)

The number of neutrophils, white blood cells that help fight infection, in a given amount of blood. Too few raises the risk of infection.

It is a count, not a percentage of the white cells. Limits are written in units that mean the same: ≥ 1.5 × 10⁹/L is ≥ 1,500 per mm³ (µL). Each lab has its own reference range.

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

Hemoglobin (Hb)

The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Live vaccines

Vaccines made with a weakened form of the germ, such as measles–mumps–rubella (MMR), chickenpox and yellow fever. They can be risky when the immune system is weakened. Flu injections are not live; the nasal flu spray is.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

What researchers measure

Primary outcomes

  1. Incidence of Treatment-Emergent Adverse Events

    The safety and tolerability of two intravitreal injections of VCN-01 will be determined with dose escalation until the maximum tolerated dose (MTD) is established based on the evaluation of adverse events and the observation of any dose-limiting toxicity (TLD).

    Time frame: 180 days

Secondary outcomes

  1. Tumor response

    Tumor response rate (ORR) to VCN-01 at 28 days post-administration.

    Time frame: 28 days

  2. VCN-01

    Virus presence in blood samples, aqueous humor, ocular surface and nasal swabs, and its difference between the viral particles before and after the treatment to evaluate the excretion profile of the CNV-01.

    Time frame: 180 days

  3. Immune response

    The presence of neutralizing antibodies in blood samples in study patients to assess the immune response.

    Time frame: 180 days

Other outcomes

  1. Histopathology of enucleated eyes after treatment with VCN-01

    Presence of VCN-01 in vitreous humor samples of enucleated eyes

    Time frame: 180 days
