Testing the Combination of Two Immunotherapy Drugs (Magrolimab and Dinutuximab) in Patients With Relapsed or Refractory Neuroblastoma or Relapsed Osteosarcoma

This phase I trial is to find out the best dose, possible benefits and/or side effects of magrolimab in combination with dinutuximab in treating patients with neuroblastoma that has come back (relapsed) or does not respond to treatment (refractory) or relapsed osteosarcoma. Magrolimab and dinutuximab are monoclonal antibodies that may interfere with the ability of tumor cells to grow and spread. The combination of magrolimab and dinutuximab may shrink or stabilize relapsed or refractory neuroblastoma or relapsed osteosarcoma. In addition, this trial may help researchers find out if it is safe to give magrolimab and dinutuximab after surgery to remove tumors from the lungs.

Stanford is currently accepting patients for this trial.

   and cured. For patients with HCV infection who are currently on treatment, they are
   eligible if they have an undetectable HCV viral load

   - Patients with a prior or concurrent malignancy whose natural history or treatment does
   not have the potential to interfere with the safety or efficacy assessment of the
   investigational regimen are eligible for this trial

   - Patients with known history or current symptoms of cardiac disease, or history of
   treatment with cardiotoxic agents, should have a clinical risk assessment of cardiac
   function using the New York Heart Association Functional Classification. To be
   eligible for this trial, patients should be class 2B or better

   - Female patients of childbearing potential must not be nursing or planning to be
   pregnant and must have a negative urine or serum pregnancy test within 30 days before

      postmenopausal for at least 2 years are not considered to be of childbearing
      potential

   - The effects of Hu5F9-G4 (magrolimab) monoclonal antibody on the developing human fetus
   are unknown and dinutuximab is known to be teratogenic. For this reason, female
   patients of childbearing potential must be willing to use one highly effective method
   of contraception (hormonal or barrier method of birth control; abstinence) prior to
   study entry, during the study and continue for 4 months after the last dose of study

      (WOCBP) and who have not had vasectomies must be willing to use a barrier method
      of contraception (condom plus spermicidal gel) and refrain from sperm donation
      during the study and for 4 months after the last dose of study treatment. If the
      partner is pregnant, male patients must use barrier method contraception (condom)
      during the study and for 4 months after the last dose of study treatment to
      prevent fetal exposure to study treatment

   - All patients 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 be obtained according to local institutional policy

   physiologically significant pericardial effusion as determined by an echocardiogram
   (ECHO), multigated acquisition scan (MUGA) or cardiac MRI. No clinically significant
   electrocardiogram (ECG) findings that in the judgment of the treating investigator
   would present a contraindication for treatment

Exclusion Criteria:

   - History of allergic reactions attributed to compounds of similar chemical or biologic
   composition to anti-GD2 monoclonal antibody (dinutuximab) or Hu5F9-G4 (magrolimab)
   monoclonal antibody or other agents used in this study

   - Uncontrolled intercurrent illness including, but not limited to, ongoing or active
   infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac
   arrhythmia, or psychiatric illness/social situations that would limit compliance with
   study requirements

   - Patients who are receiving any other investigational agents

   - Pregnant women are excluded from this study because Hu5F9-G4 (magrolimab) is a
   monoclonal antibody on the developing human fetus are unknown and dinutuximab may
   cause fetal harm. Because there is an unknown but potential risk for adverse events in
   nursing infants secondary to treatment of the mother with Hu5F9-G4 (magrolimab) or
   dinutuximab, breastfeeding should be discontinued if the mother is treated with
   Hu5F9-G4 (magrolimab) or dinutuximab

   - Patients who have received prior treatment with CD47 or SIRPalpha-targeting agents

   - Patients with red blood cell (RBC) transfusion dependence, defined as requiring more
   than 2 units of RBCs transfused during the 4-week period prior to screening. RBC
   transfusions are permitted during the screening period and prior to enrollment

   - Patients with known inherited or acquired bleeding disorders are not eligible

   - Patients with prior hemolytic anemia or Evans syndrome in the last 3 months

   - Patients with significant medical diseases that would worsen the risk-benefit ratio of
   participating in this study. This includes but is not limited to acute myocardial
   infarction within the last 6 months, unstable angina, significant acute or chronic
   infections, or severely immunocompromised state

   - Patients on the following medications at the time of study treatment initiation:

      - Immunotherapy or immunosuppressive drugs (e.g. chemotherapy or systemic
      corticosteroids) EXCEPT for the following:

         - The only exception is for patients known to require 2 mg/kg or less of
         hydrocortisone (or an equivalent dose of an alternative corticosteroid) as
         premedication for blood product administration in order to avoid allergic
         transfusion reactions. The use of conventional doses of inhaled steroids for
         the treatment of asthma is permitted, as is the use of physiologic doses of
         steroids for patients with known adrenal insufficiency

      - Growth factors (granulocyte colony stimulating factor or granulocyte macrophage
      colony stimulating factor) EXCEPT for erythropoietin and darbepoietin alpha

      - Herbal remedies with immunostimulating properties (e.g., mistletoe extract) or
      known to potentially interfere with major organ function (e.g. hypericin)

   - Patients administered a live vaccine within 28 days prior to initiation of study
   treatment

   - Patients with untreated central nervous system (CNS) metastasis.

      - Patients with previous CNS tumor involvement that has been treated and is stable
      for at least 4 weeks following completion of therapy are permitted
