Outcome Measures

Primary Outcomes (3)

  • Dose limiting toxicities

    The frequency and percentage of DLT will be presented by dose level

    During the first cycle (every cycle is 21 days) of treatment

  • Adverse events

    The frequency and percentage of AEs will be presented by dose level

    From the screening visit to the end of treatment visit (time of progressive disease or 2 years)

  • Immunogenicity

    Presence anti-drug antibody (ADA) will be listed

    From screening visit to end of treatment visit (time of progressive disease or 2 years)

Secondary Outcomes (4)

  • Overall response rate

    At every 2nd cycles until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 2 years (every cycle is 21 days)

  • Disease control rate

    At every 2nd cycles until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 2 years (every cycle is 21 days)

  • Progression free survival

    From screening visit to end of treatment visit (time of progressive disease or 2 years)

  • Overall survival

    From screening visit to date of patient's death (assessed up to 2 year after end of treatment visit)

Other Outcomes (11)

  • Pharmacokinetic parameters - Cmax

    From screening visit to end of treatment visit (time of progressive disease or 2 years)

  • Pharmacokinetic parameters - Cmin

    From screening visit to end of treatment visit (time of progressive disease or 2 years)

  • Pharmacokinetic parameters - AUC0-t

    From screening visit to end of treatment visit (time of progressive disease or 2 years)

  • +8 more other outcomes

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Diagnosed with primary glioblastoma by histopathological examination and confirmed recurrent glioblastoma by magnetic resonance imaging (MRI) scans after completing standard of care (Stupp protocol) concomitant temozolomide chemotherapy with radiotherapy (CCRT)
  • At least one confirmed measurable lesion by RANO criteria
  • Karnofsky Performance Status (KPS) ≥80
  • A person who satisfies the following criteria in haematologic, renal, and hepatic function tests performed within 7 days prior to screening:
  • Haematologic tests
  • Absolute neutrophil count (ANC) ≥ 1.5 x 109/L
  • Platelets ≥ 100 x 109/L
  • Haemoglobin ≥ 9.0 g/dL
  • Blood coagulation tests
  • Prothrombin time (PT) ≤ 1.5 x Upper limit of normal (ULN)
  • Activated partial thromboplastin time (aPTT) ≤ 1.5 x ULN
  • Hepatic function tests
  • Total bilirubin ≤ 1.5 x UNL
  • Aspartate aminotransferase (AST) or alanine aminotransferase (ALT) ≤ 2.5 x ULN (≤ 5 x ULN in case of liver metastasis)
  • Renal function test
  • +3 more criteria

You may not qualify if:

  • Has a known additional malignancy that is progressing or has required active treatment within the past 2 years. (Note: Patients with basal cell carcinoma of the skin, squamous cell carcinoma of the skin or carcinoma in situ \[e.g., breast carcinoma, cervical cancer in situ\] controlled by curative therapy are not excluded)
  • Has received prior radiotherapy within 2 weeks of start of study treatment.

A 1-week washout is permitted for palliative radiation (≤2 weeks of radiotherapy) to non-CNS disease
  • Has a history of (non-infectious) pneumonitis/interstitial lung diseases that required steroids or current pneumonitis/interstitial lung disease
  • Has an active infection requiring systemic therapy
  • Uncontrolled hypertension (systolic blood pressure \[SBP\]\> 150 or diastolic blood pressure \[DBP\]\> 90 mmHg)
  • Uncontrolled seizures
  • Class III or IV heart failure by New York Heart Association (NYHA) classification
  • Has oxygen-dependent chronic disease
  • History of abdominal fistula or gastrointestinal perforation within 6 months prior to start of study drug
  • History of serious gastrointestinal haemorrhage within 6 months prior to start of study drug
  • History of severe arterial thromboembolic event within 12 months of start of study drug
  • Serious grade 4 venous thromboembolic event including pulmonary embolism
  • History of hypertensive crisis or hypertensive encephalopathy
  • History of posterior reversible encephalopathy syndrome
  • Planned surgery within 4 weeks post last dose
  • +16 more criteria
