Clinical Trial Summary

Limited progress has been made in identifying novel targets that may be therapeutic for Osteosarcoma(OS) and there remains an urgent need for the development of new agents that are effective in improving survival. From this perspective, repurposing already proven targets in other tumors may offer new opportunities for OS in children and young adults. Anecdotal evidence of anti-GD2 therapy exists in OS from prior Phase 1 trials that included patients with OS.


Description:

Anecdotal evidence of anti-GD2 therapy exists in OS from prior Phase 1 trials that included patients with OS. In a Phase 1/1B trial of the murine antibody (14.2G2a) plus IL2, 2/33 patients had OS. One patient had multiple bone metastases and received 1 cycle of therapy. Two months later, repeat scans showed a complete response. This patient remained disease free for 8 months but subsequently relapsed. The Children's oncology group recently investigated the use of dinutuximab monotherapy in patients with recurrent pulmonary OS in complete surgical remission in a single-arm phase II study (AOST1421). Patients received 5 cycles of dinutuximab 70mg/m2/cycle with GM-CSF in 2 different dinutuximab infusion schedules: 35mg/m2/day over 20 hours (2-day) and 17.5mg/m2/day over 10 hours (4-day) schedule. The primary end point was Disease Control Rate (DCR), defined as the proportion of patients' event-free at 12 months from enrollment and success was defined as ≥16/ 39 patients (> 40%) event-free at 12 months from enrollment. The preliminary results of this study were showed at ASCO 2020. Thirty-nine patients were eligible and evaluable (median age 15 yr). One of 136 administered therapy cycles met the criteria for unacceptable toxicity when 1 patient receiving the 2-day schedule died after cycle 2 due to an unknown cause and 1 patient experienced grade 4 neurotoxicity (depressed level of consciousness and respiratory depression) attributed as probably related to the protocol therapy. The protocol was revised to allow only the 4-day schedule. Other ≥ Grade 3 toxicities occurring in > 10 % of participants were predictable dinutuximab toxicities such as pain, diarrhea, hypoxia and hypotension. A DCR of 30.7% (95% CI 17- 47%) was found, as 27/39 patients experienced an event. The final official results have not been published yet, and analyses are ongoing. A humanized version of the anti-GD2 antibody, Naxitamab (hu3F8), developed at Memorial Sloan Kettering Cancer Center, is currently being tested for efficacy against recurrent OS (NCT02502786). Rationale dose and schedule of Dinutuximab beta in MaQ trial. The recommended dosage of Dinutuximab (Unituxin, United Therapeutics) is 17.5 mg/m2/day administered IV over 10-20 hours for 4 consecutive days for a maximum of 5 cycles. In AOST1421, patients with recurrent pulmonary OS received 5 cycles of dinutuximab 70mg/m2/cycle with GM-CSF in 2 different infusion schedules: 35mg/m2/day over 20 hours (2-day) (experimental infusion) and 17.5mg/m2/day over 10 hours (4-day) schedule. However, during this trial, 2 serious adverse events (n=1 death, n=1 grade 4 neurotoxicity), possibly related to the experimental infusion schedule of dinutuximab were reported. In light of these events, the protocol was modified for the remainder of the study to allow only the 4-day schedule. In the EU, Dinutuximab beta is approved for high-risk NB patients at the recommended dosage of 100 mg/m2 per course as either an 8-hour short-term i.v. infusion over 5 consecutive days (STI), or as a long-term i.v. infusion over 10 consecutive days (LTI). A pharmacokinetics study of LTI dinutuximab beta showed that this regimen results in higher plasma exposure at time points preceding subsequent antibody infusions after cycle 1, allowing for a persistent activation of antibody effector mechanisms over the entire treatment period. Moreover, LTI led to a less toxic profile compared with STI regimen. Data on Dinutuximab dosage and safety are based on studies enrolling primary refractory or relapsed NB or first-line NB children with either complete response or at MRD. OS is the most common primary malignant bone tumor in AYA, thus we expect to include older patients than NB patients, that notably experience greater toxicity from antitumor therapies. Moreover, the present trial will enroll patients who have experienced OS R/R and have already received at least one line of standard treatment. Furthermore, so far, PK data are lacking for the adolescent population. For these reasons, the patients enrolled in this study with OS R/R will received Dinutuximab beta (Qarziba) 14 mg/mq/day, for 5 days (total dose: 70mg/sqm/cycle) i.v. continuous infusion. Each cycle will last 28 days.

Eligibility Inclusion Criteria: - Provision of signed and dated, written informed consent from each patient or patient's legally acceptable representative, parent (s) or legal guardian in accordance with regional laws or regulations and the patient's assent, when applicable, before any study-specific activity, including screening evaluation, is performed. For patients who reach the age of legal consent during the clinical study, notification may be required and a new consent form may need to be signed by the patient. - Histologically confirmed high-grade osteosarcoma which is relapsed or refractory (ONLY patients in first or second relapse will be eligible). Histological confirmation from initial diagnosis or relapse is acceptable. - Disease status: subjects must have achieved a complete or partial response after a second or further line of systemic therapy (with or without surgery) as defined by the following criteria: - Complete Response = disappearance of all target and non-target lesions - Partial Response = at least 30% decrease in the sum of the longest diameter (LD) of target lesions, taking as reference the baseline sum LD of the last episode of relapse or recurrence. If a partial response is achieved, only patients with a focal localized disease at any site must be enrolled (for patients with lung disease a maximum of 2 lung unilateral nodules will be accepted). - Age: = 1 to < 25 years old at the time of signing the informed consent form. - Performance Level: Karnofsky Performance Status = 60% for participants > 16 years old or Lansky Play Score = 60% for pediatric participants = 16 years old. Subjects who are unable to walk because of paralysis and/or previous surgeries will be considered ambulatory for the purpose of assessing their performance score. - Subjects must have recovered to < Grade 2 per the NCI CTCAE v 4.03 or to baseline from any non-hematologic toxicities (except alopecia) due to previous therapy. - Life expectancy = 3 months. - Completed previous line of treatment (systemic therapy with or without surgery) within 28 days prior the first dose of Dinutuximab Beta. - Adequate bone marrow function independent of transfusion for at least 7 days prior to screening and independent of growth factor support for at least 14 days prior to screening - Adequate organ function - Normal ventricular ejection fraction (LV ejection fraction > 50%). - Availability of paraffin tumor material and/or fresh frozen tumor sample of the most recent biopsy.
