Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
DCSZ11 will be administered as monotherapy and in combination with pembrolizumab in patients with advanced-stage or metastatic solid tumors. The Escalation Phase will be followed by a Dose Expansion/Optimization Phase (Phase 1b) to further characterize safety, PK, pharmacodynamics, and evidence of antitumor activity of DCSZ11 in combination with pembrolizumab in select relapsed/refractory (R/R) solid tumors and, if desired, optimize the DCSZ11 dose.
Phase 1a - Dose Escalation Phase 1a is a dose escalation study of DCSZ11 as monotherapy in Part 1 and in combination with pembrolizumab in Part 2. DCSZ11 dose levels may be escalated up to the maximum tolerated dose level or to the maximum planned dose level of 20mg/kg. Patients will receive DCSZ11 IV initially every 3 weeks.
Phase 1b - Dose Expansion/Optimization in Select Indications Phase 1b will evaluate DCSZ11 in combination with pembrolizumab in select indications following a Simon two-stage like design that allows for dose optimization.
Phase 1b - Standard-of-Care (SOC) Combinations Safety Lead-in/ Expansion in Select Indications A safety lead-in using the BOIN design followed by a Simon two-stage like design will be used to evaluate DCSZ11 in combination with standard of care in select indications. Patients will receive DCSZ11 IV at one of the dose escalation dose levels/schedule (or dose/schedule selected for optimization/expansion). Once the safety lead-in is completed, a Bayesian continuous toxicity monitoring will be used to monitor for unacceptable toxicity in expansions.

6. Systemic venous thrombotic events (e.g., deep vein thrombosis) or pulmonary arterial events (e.g., pulmonary embolism) within 1 month prior to the first dose of study drug. Patients with venous thrombotic events prior to the first dose of study drug on stable anticoagulation therapy are eligible.
7. Left ventricular ejection fraction (LVEF) \< 50%.
8. Major surgery within 4 weeks and minor surgery within 2 weeks of the first dose of study drug; following surgeries, all surgical wounds must be healed and free of infection or dehiscence. Patients must have recovered and not have ongoing surgical complications.
9. Marked proteinuria ≥ 2 g/24 hours and/or nephrotic syndrome. Patients with proteinuria 2+ or greater urine dipstick reading should undergo further assessment, e.g., a 24-hour urine collection.
10. Known allergy or hypersensitivity to any component of the study drugs or, for patients receiving the imaging agent, any component of the imaging agent.
11. For patients receiving a combination with pembrolizumab:
1. Received any prior immunotherapy and was discontinued from that treatment due to a Grade 3 or higher immune-related adverse event (except endocrine disorders that can be treated with replacement therapy) or was discontinued from that treatment due to Grade 2 myocarditis or recurrent Grade 2 pneumonitis.
2. Severe hypersensitivity (≥Grade 3) to pembrolizumab and/or any of its excipients.
3. Autoimmune disease requiring systemic immunosuppressive therapy within the past 2 years. Hormone therapy (e.g., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency) is not considered an excluded form of systemic treatment of an autoimmune disease.
4. Diagnosis of immunodeficiency or is receiving chronic systemic steroid therapy (in dosing exceeding 10 mg daily of prednisone equivalent) or any other form of immunosuppressive therapy within 7 days prior the first dose of study intervention.
5. History of radiation therapy to the lung that is \>30 Gy within 6 months of the first dose of study treatment
6. History of (noninfectious) pneumonitis/interstitial lung disease that required steroids or has current pneumonitis/interstitial lung disease.
7. History of allogeneic tissue or solid organ transplant.
12. Receipt of any live or live-attenuated vaccine within 4 weeks of initiation of study treatment. Administration of killed vaccines is allowed.
13. Has active infection requiring systemic therapy.
14. Patients that are hepatitis B virus surface antigen (HBsAg) seropositive and with detectable hepatitis B virus (HBV) viral load. Note: Patients with positive HBsAg can been enrolled if they have received HBV antiviral therapy for at least 4 weeks, and have undetectable HBV viral load prior to initiation of study treatment. Patients should remain on antiviral therapy throughout study intervention and follow local guidelines for HBV antiviral therapy post completion of study intervention.
15. Patients with history of hepatitis C virus (HCV) infection and detectable HCV viral load at screening. Note: Patients must have completed curative antiviral therapy at least 4 weeks prior to initiation of study treatment.
16. History of any of the following ≤6 months before first dose: congestive heart failure New York Heart Association Grade III or IV, unstable angina, myocardial infarction, unstable symptomatic ischemic heart disease, uncontrolled hypertension despite appropriate medical therapy, ongoing symptomatic cardiac arrhythmias \>Grade 2, or any other serious cardiac condition (e.g., pericardial effusion or restrictive cardiomyopathy). Chronic atrial fibrillation on stable anticoagulant therapy is allowed.
17. History or current evidence of any condition, therapy, laboratory abnormality, psychiatric illness, social circumstances, or other circumstance that might compromise the ability to provide informed consent, confound the results of the study, or interfere with the patient's ability to cooperate with the requirements of the study, such that it is not in the best interest of the patient to participate, in the opinion of the treating investigator.
18. Female patients who are pregnant or lactating and breastfeeding.
