Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - MDNA11
Treatment: Drugs - Pembrolizumab (KEYTRUDA®)

Experimental: MDNA11 - MDNA11 is a long-acting "beta-only" recombinant interleukin-2 (rIL-2) albumin fusion


Treatment: Drugs: MDNA11
MDNA11 will be administered, IV on a once every 2 weeks (Q2W) dosing schedule. Provisional dose cohorts for monotherapy dose escalation doses ranging from 0.003 to 0.6 (mg/kg): until determining the monotherapy Recommended Dose for Expansion (mRDE).

Treatment: Drugs: Pembrolizumab (KEYTRUDA®)
MDNA11 will be administered in combination with pembrolizumab, IV. MDNA11 dose range to be evaluated in combination with pembrolizumab until determining the combination Recommended Dose for Expansion (cRDE).

Key exclusion criteria
1. Last administration of prior antitumor therapy:

* Prior systemic anti-cancer therapy including investigational agents within 4 weeks (could consider shorter interval for kinase inhibitors or other short half-life drugs) prior to start of treatment.
* Prior radiotherapy within 2 weeks prior to start of treatment or has had a history of radiation pneumonitis. A 1-week washout is required for palliative radiation (<2 weeks of radiotherapy) to non-CNS disease.
* Radiation therapy to the lung that is > 30Gy within 6 months prior to start of treatment.
* Currently participating in or has participated in a study of an investigational agent or has used an investigational device within 4 weeks prior to start of treatment. Concomitant participation in an observational study must be discussed on a case-by-case basis with the MM for approval.
2. Has known active CNS metastases and/or carcinomatous meningitis. Patients with previously treated brain metastases may participate provided they are radiologically stable, i.e., without evidence of progression for at least 4 weeks by repeat imaging (note that the repeat imaging should be performed during study screening), clinically stable and without requirement of steroid treatment for at least 14 days prior to start of treatment, subject to discussion with MM.
3. Active malignancy (other than the disease under treatment in the study) within the previous 3 years except for curable cancers.
4. Condition requiring long-term systemic treatment with either corticosteroids > 10 mg daily prednisone equivalent or any other form of immunosuppressive therapy within 7 days prior to start of treatment.
5. Clinically significant active, known or suspected autoimmune disease, or diseases that can be exacerbated with immunotherapy.
6. Severe pulmonary, cardiac or other systemic disease.
7. Known hepatitis B or C virus infection.
8. Females who are pregnant or lactating or planning to become pregnant during the study.
9. Has had an allogeneic tissue/solid organ transplant.
10. Active infection requiring systemic therapy.
11. Any medical, emotional or psychiatric condition that interfere with the patient's ability to adhere to the protocol
12. Any other underlying medical conditions that, in the Investigator's opinion, will make the administration of study drug(s) unsafe or obscure the interpretation of toxicity determination or adverse events.
13. Known severe hypersensitivity to any component of study drug(s).
14. Inability to comply with study and follow up procedures as judged by the Investigator.
