Study Description

 

 This study is eligible for STEP-1 funding. Find more information here

 

This phase I trial studies the side effects and best dose of pembrolizumab and to see how well it works in treating younger patients with high-grade gliomas (brain tumors that are generally expected to be fast growing and aggressive), diffuse intrinsic pontine gliomas (brain stem tumors), brain tumors with a high number of genetic mutations, ependymoma or medulloblastoma that have come back (recurrent), progressed, or have not responded to previous treatment (refractory). Immunotherapy with monoclonal antibodies, such as pembrolizumab, may induce changes in the body's immune system, and may interfere with the ability of tumor cells to grow and spread.

Study Description

Brief Summary:

This single site, single-arm, non-randomized, dose escalation phase I toxicity clinical trial will assess primarily the safety and secondarily the efficacy of episcleral topotecan in patients with active residual or recurrent intraocular retinoblastoma in at least one eye following completion of first-line therapy.

Detailed Description:

Retinoblastoma is the most common pediatric malignant intraocular tumour and originates from the retina. Treatment of eyes with advanced intraocular retinoblastoma remains a challenge. The historic standard of care for patients with unilateral disease is enucleation and for those with bilateral disease, a variety of modalities have been tried. These include radiation therapy, systemic chemotherapy, periocular administration of chemotherapy, selective intra-arterial chemotherapy, and intravitreal chemotherapy. Unfortunately, all of these modalities are associated with significant morbidity and investigators are looking for new ways to treat these patients either with novel directed drug delivery methods or with new less toxic agents. This study will evaluate the safety and efficacy of topotecan delivered directly to the eye using a novel sustained-release topotecan episcleral plaque (also referred to as a Chemoplaque) in patients with active residual or recurrent intraocular retinoblastoma in at least one eye following completion of first-line therapy. The study intervention involves the insertion and removal of the Chemoplaque, examinations under anaesthesia (EUAs), visits to clinic to monitor for adverse events throughout, and post plaque removal toxicity evaluation. EUAs, clinic visits and laboratory tests are standard of care for retinoblastoma patients.

Inclusion Criteria
  1. Age. Participants must be <18 years of age.
  2. Diagnosis and Treatment. Participants must have: (i) active residual or recurrent intraocular retinoblastoma in at least one eye following completion of first-line therapy (chemotherapy, systemic or intra-arterial, focal therapy or brachytherapy) or (ii) unilateral Group D retinoblastoma at diagnosis with no previous treatment.
  3. One eye will be the Study Eye. When participants have two eyes with retinoblastoma, the eye with worst disease or best vision potential will be designated the Study Eye. There will only be one eye per child treated in this Phase I study, since treatment of two eyes would double the systemic dose of drug. The Non-study eye will be treated by standard of care, with only focal therapy during the Study Period, if required.
  4. Disease status. Study eye must have vision potential and no clinical features suggestive of high risk of extraocular extension.
  5. Performance status. Lansky play score ≥ 50 if <16 years of age; Karnofsky performance scale of ≥ 50 if ≥16 years of age (Appendix I)
  6. Organ function:

    1. Adequate bone marrow function and platelet count
    2. Adequate renal function
    3. Adequate liver function
  7. Pregnancy prevention. Females of reproductive potential must agree to the use of highly effective contraception during study participation and for an additional 40 days after the end of the Chemoplaque administration
  8. Informed consent. All participants and/or their parents or legally authorized representatives must have the ability to understand and the willingness to sign a written informed consent. Assent, where appropriate, will also be obtained.
Exclusion Criteria
  1. Disease status. Participants known to have any of the following:

    1. tumour involving the optic nerve rim
    2. clinical or EUA evidence of extraocular extension
    3. evidence of metastatic retinoblastoma
    4. existing neuroimaging showing suspicion of, or definitive, optic nerve invasion, trilateral retinoblastoma or extra-ocular extension.
  2. Allergy. Participants with reported allergy to topotecan, camptothecin or derivatives thereof.
  3. Concomitant treatment. Participants may not receive chemotherapy or other focal retinoblastoma therapy or any other investigational agent within 3 weeks of the placement and removal of the Chemoplaque, nor while the Chemoplaque is in situ.
  4. Uncontrolled intercurrent illness. Participants with known uncontrolled intercurrent illness that, in the investigator's opinion, would put the participant at undue risk or limit compliance with the study requirements.
  5. Febrile illness. Participants with clinically significant febrile illness (as determined by the investigator) within one week prior to initiation of protocol therapy.
  6. Pregnancy and lactation. Females of reproductive potential must have a negative serum pregnancy test within 72 hours prior to initiation of protocol therapy. Due to the unknown but potential risk for adverse events (AEs) in nursing infants secondary to treatment of the mother with the study agents, breastfeeding must be discontinued if the mother is treated on study.
  7. Compliance. Any condition of diagnosis that could in the opinion of the Principal Investigator or delegate interfere with the participant's ability to comply with the study instruction, might confound the interpretation of the study results, or put the participant at risk.

Study Description

This phase II trial tests the safety and side effects of adding melphalan (by injecting it into the eye) to standard chemotherapy in early treatment of patients with retinoblastoma (RB). RB is a type of cancer that forms in the tissues of the retina (the light-sensitive layers of nerve tissue at the back of the eye). It may be hereditary or nonhereditary (sporadic). RB is considered harder to treat (higher risk) when there are vitreous seeds present. Vitreous seeds are RB tumors in the jelly-like fluid of the eye (called the vitreous humor).

The term, risk, refers to the chance of the cancer not responding to treatment or coming back after treatment. Melphalan is in a class of medications called alkylating agents. It may kill cancer cells by damaging their deoxyribonucleic acid (DNA) and stopping them from dividing. Other chemotherapy drugs given during this trial include carboplatin, vincristine, and etoposide. Carboplatin is in a class of medications known as platinum-containing compounds. It works in a way similar to the anticancer drug cisplatin, but may be better tolerated than cisplatin. Carboplatin works by killing, stopping or slowing the growth of cancer cells. Vincristine is in a class of medications called vinca alkaloids. It works by stopping cancer cells from growing and dividing and may kill them. Etoposide is in a class of medications known as podophyllotoxin derivatives. It blocks a certain enzyme needed for cell division and DNA repair and may kill cancer cells.

Adding melphalan to standard chemotherapy early in treatment may improve the ability to treat vitreous seeds and may be better than standard chemotherapy alone in treating retinoblastoma.

 

PRIMARY OBJECTIVE:

I. To determine the feasibility of administering intravitreal melphalan by cycle 6 when given in combination with systemic carboplatin, vincristine, and etoposide (CVE) for the treatment of Group D retinoblastoma with vitreous seeding.

SECONDARY OBJECTIVES:

I. To determine the safety and toxicity profile associated with intravitreal melphalan in combination with systemic CVE for the treatment of Group D retinoblastoma with vitreous seeding.

II. To evaluate the efficacy of intravitreal melphalan in conjunction with systemic chemotherapy in Group D intraocular retinoblastoma with vitreous seeding.

EXPLORATORY OBJECTIVES:

I. To determine if eyes that become eligible for injection at cycle 3 or later would have been eligible for injection at diagnosis by retrospective central review of examination under anesthesia (EUA) and ultrasound biomicroscopy (UBM) images from diagnosis.

II. To validate and standardize the extraction, storage and collection protocols across multiple centers to demonstrate that aqueous humor from eyes undergoing therapy have high enough tumor-derived deoxyribonucleic acid (DNA) concentration for whole genome sequencing and RB1 testing.

III. To explore the relationship between highly-recurrent retinoblastoma (RB) somatic copy number alterations (SCNAs) and ocular salvage as well as tumor fraction (% of tumor DNA) as a marker of minimal residual disease and risk of intraocular disease relapse.

IV. To evaluate the effects of intravitreal melphalan therapy in the histopathology of enucleated eyes for progressive or recalcitrant retinoblastoma while on therapy.

V. To evaluate the long-term visual potential of eyes salvaged using intravitreal therapy.

 

OUTLINE:

CYCLES 1-2: Patients receive CVE regimen consisting of: carboplatin intravenously (IV) over 15-60 minutes on days 1 and 2 of each cycle, vincristine IV on day 1 of each cycle, and etoposide IV over 90-120 minutes on day 1 and 2 of each cycle. Treatment repeats every 28 days for up to 2 cycles in the absence of disease progression or unacceptable toxicity. Patients also undergo ultrasound biomicroscopy (UBM) and imaging of the eye during a procedure called examination under anesthesia (EUA) at baseline and prior to each cycle. NOTE: UBM is completed prior to cycle 1 only.

CYCLES 3+: Patients receive CVE regimen as in cycles 1-2. Patients also undergo EUA prior to each cycle to determine eligibility to receive melphalan. If found eligible, patients receive intravitreal injection of melphalan once between days -14 to 14 of each cycle. Patients who are not eligible for melphalan for any cycle receive CVE only regimen for that cycle. Treatment repeats every 28 days for up to 4 cycles in the absence of disease progression or unacceptable toxicity. NOTE: Patients may be eligible to receive additional cycles of melphalan alone (maximum of 6 injections).

Additionally, patients undergo magnetic resonance imaging and may undergo aqueous humor and tissue sample collection throughout the trial.

After completion of study treatment, patients are followed up at 4 weeks, then every 3 months for 1 year, and then every 3-6 months for years 2-5

Study Description

This is a Phase 1/2, multicenter, open-label trial of avapritinib in patients aged 2 to less than 18 years of age with with relapsed/refractory (R/R) solid tumors with mutations (including non-synonymous point mutations, insertions, and deletions) in KIT or PDGFRA, or gliomas with the H3K27M mutation, and no available alternative treatment options. This is a single-arm trial in which all patients will receive avapritinib. The study consists of 2 parts: dose confirmation, safety, and PK (Part 1) and initial efficacy, safety, and PK at the Part 2 recommended dose (Part 2).

Inclusion Criteria
  • Patient has confirmed diagnosis of a R/R solid or CNS tumor with a mutation in KIT or PDGFRA (confirmed by local mutational testing of tumor sample) that has progressed despite standard therapy and no alternative treatment option is available OR Confirmed diagnosis of H3K27M mutant glioma that has failed standard therapy or for which no standard therapy that may convey clinical benefit exists, as judged by the Investigator.
  • Patients with CNS disease should be on a stable dose (≤10% change) of corticosteroids for at least 7 days prior to first dose of avapritinib, with no plans for dose escalation.

Study Description

Brief Summary:

This is an open-label, multi-center Phase 1/2 study of oral LOXO-292 in pediatric participants with an activating rearranged during transfection (RET) alteration and an advanced solid or primary CNS tumor.

Detailed Description:

This study includes 2 parts: phase 1 (dose escalation) and phase 2 (dose expansion). In phase 1, participants will be enrolled using a rolling 6 dose escalation scheme. The starting dose of LOXO-292 is equivalent to the adult recommended phase 2 dose of 160 milligrams (mg) twice a day (BID). Once the maximum tolerated dose (MTD) and/or recommended phase 2 dose (RP2D) is identified, participants will be enrolled to one of four phase 2 dose expansion cohorts depending on tumor histology and tumor genotype. Cycle length will be 28 days.

With a recent amendment, stable patients who have been on study for over 2 years may discuss the option of a drug treatment holiday with their clinical team.
