What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tests whether adding a chemotherapy drug (melphalan) injected directly into the eye can help treat a childhood eye cancer called retinoblastoma, especially when tumor seeds are floating in the eye fluid. About 26 children with newly diagnosed retinoblastoma will receive standard chemo plus these eye injections. The goal is to see if this combination is safe and can better control the disease, potentially saving the eye.

Inclusion Criteria: * Patient must be \< 18 years of age at enrollment * Patient must have newly diagnosed intraocular (localized) retinoblastoma and meet one of the following criteria: * Unilateral Group D retinoblastoma with vitreous seeding; OR * Bilateral retinoblastoma with worst eye Group D, with vitreous seeding present and the contralateral eye is Group A-C; OR * Bilateral Group D retinoblastoma with at least one eye with vitreous seeding; OR * Bilateral retinoblastoma with one Group D eye with vitreous seeding and one Group E eye where the Group E eye has been enucleated prior to any therapy. Note exclusion for high-risk features * Bilateral retinoblastoma with one Group D eye with vitreous seeding and one Group E eye where the Group E eye has not been enucleated prior to any therapy at the discretion of the treating physician. Note exclusion for patients with evidence of metastatic or extra orbital spread * Patients must have a performance status corresponding to Eastern Cooperative Oncology Group (ECOG) scores of 0, 1 or 2. Use Karnofsky for patients \> 16 years of age and Lansky for patients =\<16 years of age * Peripheral absolute neutrophil count (ANC) \>= 750/uL (must be performed within 7 days prior to enrollment unless otherwise indicated) * Platelet count \>= 75,000/uL (transfusion independent) (must be performed within 7 days prior to enrollment) * A serum creatinine based on age/sex as follows (must be performed within 7 days prior to enrollment; must be repeated prior to the start of protocol therapy if \> 7 days have elapsed from their most recent prior assessment): * 1 month to \< 6 months = 0.4 (male and female) * 6 months to \< 1 year = 0.5 (male and female) * 1 to \< 2 years = 0.6 (male and female) * 2 to \< 6 years = 0.8 (male and female) * 6 to \< 10 years = 1.0 (male and female) * 10 to \< 13 years = 1.2 (male and female) * 13 to \< 16 years = 1.5 (male) and 1.4 (female) * \>= 16 years = 1.7 (male) and 1.4 (female) OR - a 24-hour urine Creatinine clearance \>= 70 mL/min/1.73 m\^2 OR - a glomerular filtration rate (GFR) \>= 70 mL/min/1.73 m\^2. GFR must be performed using direct measurement with a nuclear blood sampling method OR direct small molecule clearance method (iothalamate or other molecule per institutional standard) * Note: Estimated GFR (eGFR) from serum creatinine, cystatin C or other estimates are not acceptable for determining eligibility * For patients \< 1 month of age, serum creatinine levels must be \< 1.5 x the treating institution's creatinine upper limit of normal (ULN) for patients \< 1 month of age or the creatinine clearance or radioisotope GFR must be \>= 70 mL/min/1.73 m\^2 * The threshold creatinine values were derived from the Schwartz formula for estimating GFR utilizing child length and stature data published by the Center for Disease Control (CDC) * Total bilirubin =\< 1.5 x upper limit of normal (ULN) for age (must be performed within 7 days prior to enrollment; must be repeated prior to the start of protocol therapy if \> 7 days have elapsed from their most recent prior assessment) * Serum glutamate pyruvate transaminase (SGPT) (alanine aminotransferase \[ALT\]) =\< 135 U/L (must be performed within 7 days prior to enrollment; must be repeated prior to the start of protocol therapy if \> 7 days have elapsed from their most recent prior assessment) * Note: For the purpose of this study, the ULN for SGPT (ALT) has been set to the value of 45 U/L Exclusion Criteria: * Patients with evidence of metastatic or extra-orbital spread * Patients must not have an invasive infection at time of protocol entry * Patients must not have had any prior anti-cancer therapy other than cryotherapy and/or laser therapy (green or infrared) to the study eye(s) and non-study eye, including systemic chemotherapy, intra-arterial chemotherapy, radioactive plaque, brachytherapy, or radiation therapy. * Note: A study eye is defined as being Group D with vitreous seeding. Patients may have had enucleation of one eye as long as the remaining eye is Group D with vitreous seeds * Patients with bilateral disease who undergo enucleation of a Group E eye prior to initiation of therapy and show evidence of high-risk histopathology features in the enucleated eye. High-risk histopathology includes choroid involvement \>= 3 mm, post lamina optic nerve involvement, full thickness scleral invasion or optic nerve invasion to the cut end * Female patients who are pregnant since fetal toxicities and teratogenic effects have been noted for several of the study drugs. A pregnancy test is required for female patients of childbearing potential * Lactating females who plan to breastfeed their infants * Sexually active patients of reproductive potential who have not agreed to use an effective contraceptive method for the duration of their study participation * All patients and/or their parents or legal guardians must sign a written informed consent * All institutional, Food and Drug Administration (FDA), and National Cancer Institute (NCI) requirements for human studies must be met
