About
To evaluate MEDI9197 when administered by intratumoral injection to subjects with solid tumors and in combination with durvalumab in subjects with solid tumors.
Full description
This is a multicenter, open-label study to evaluate the TLR 7/8 agonist MEDI9197 delivered by IT injection to subjects with solid tumors and in combination with durvalumab in subjects with solid tumors. The study has a dose escalation design using mTPI-2 to evaluate a range of doses.

Exclusion Criteria:
Any of the following would exclude the subject from participation in the study:
- Subjects who have received prior immunotherapy [(including but not limited to CTLA-4, oncolytic virus, oncolytic peptide-all require 100 day washout), programmed death ligand (PDL)-1, or programmed cell death 1 antagonists-both require 14 day washout)] are NOT permitted to enroll, with protocol exceptions.

- Requires continuous (daily) anticoagulation or antiplatelet therapy (including anti aggregants), acetylsalicylic acid (ASA) or nonsteroidal anti-inflammatory drugs (NSAIDs).
- History of coagulopathy resulting in uncontrolled bleeding or other bleeding disorders.
- Rapidly progressing disease per protocol.
- Untreated or uncontrolled central nervous system (CNS) involvement.
- Any concurrent chemotherapy, immunotherapy, or biologic or hormonal therapy for cancer treatment; with exceptions per protocol.
- Unresolved toxicities from prior anticancer therapy, defined as having not resolved to NCI CTCAE v4.03 Grade 0 or 1, with exception of alopecia, vitiligo.
- Uncontrolled concurrent illness.
- Cardiac exclusions: New York Heart Association Class 3 or 4 congestive heart failure, uncontrolled hypertension, acute coronary syndrome within 6 months, clinical important cardiac arrhythmia, mean QTC interval corrected for heart rate >500ms.

- Receipt of any systemic anticancer therapy not mentioned above within the last 2 weeks or 5 half-lives.
- Cognitive disorder such that informed consent cannot be obtained directly from the subject
- Subjects who have previously participated in this study and received MEDI9197, or concurrent enrollment in another clinical study involving an investigational treatment.
- Subjects who have received prior TLR agonists, both systemic and topical.
- Patients who have received prior therapeutic radiation within 28 days of dosing. All toxicities from prior radiotherapy must have resolved to ≤ Grade 1 or baseline prior to dosing.
- Body weight < 35 kg
- Subjects enrolling in Part 3 (ie, receiving durvalumab) must not have a history of interstitial lung disease or pneumonitis.
