Clinical Trial Summary

This study will test an investigational drug called AZD1390 in combination with radiation therapy for the treatment of brain tumors. This is the first time AZD1390 is being given to patients. This study will test safety, tolerability and PK (how the drug is absorbed, distributed and eliminated) of ascending doses of AZD1390 in combination with distinct regimens of radiation therapy

Description:

This first time-in patients (FTIP), open-label, multicentre study of AZD1390 will be conducted in the United States and in the United Kingdom, and it consists of three treatment arms: Arm A, B, C. This Phase 1 study will assess safety and tolerability of AZD1390 in combination with radiation therapy (RT) in brain malignancies. The combination cohorts have been designed to assess escalating cumulative doses of AZD1390 in settings with 3 different radiation treatment regimens:

• Arm A: 35 Gy over 2 weeks with intensity-modulated radiation therapy (IMRT) in patients with recurrent Glioblastoma Multiforme (GBM)

• Arms B: 30 Gy over two weeks with whole brain radiation therapy (WBRT)/ partial brain radiation therapy (PBRT) in patients with brain metastases. **Arm B has now closed to recruitment**

• Arm C: 60 Gy over 6 weeks (IMRT) in patients with primary GBM Each arm provides standard of care RT for the disease setting indicated with the experimental agent being administered in dose escalating cohorts.

Eligibility

Inclusion Criteria:

• Provision of formalin-fixed paraffin embedded tissue sample from primary or metastatic disease

• Karnofsky Performance Score of =60.

• Additional Inclusion Criteria Specific for Arm A:

• Histologically proven diagnosis of GBM. Patients who have had RT for low-grade glioma (LGG) or grade 3 glioma and have subsequently relapsed to histologically confirmed GBM can be considered

• A radiological diagnosis of recurrent/relapsed or progressive disease according to RANO criteria.

• Completion of first-line radiation at least 6 months prior to Cycle 1 Day 1.

• Patients with tumor-induced seizures must be well controlled on a stable anti-epileptic treatment

• Evidence of severe pulmonary infections, as judged by the investigator

• With the exception of alopecia, any unresolved toxicities from prior therapy greater than National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE 4.03) Grade 1 at the time of starting study treatment and patients with chronic Grade 2 unresolved toxicities may be eligible

Additional Exclusion criteria for Food Effect Assessment (Arm A):

• Diabetes Type I, Type II, or steroid-induced diabetes.

• Undergoing systemic steroid treatment *Note: the optional food effect assessment is currently not open to enrolment*
