DCSZ11-101: This study is assessing the effects of a drug called DCSZ11, when given alone and in combination with immunotherapy (called pembrolizumab) in people with advanced or metastatic solid cancersA Phase 1, Multicenter, Open-Label, Dose Escalation and Expansion Study to Assess Safety, Tolerability, Pharmacokinetics, Pharmacodynamics of DCSZ11 as a Monotherapy and in Combination in Patients With Advanced or Metastatic Solid Tumors

Clinical summary

Summary

This study will include a dose escalation phase and a dose expansion phase.

Participants will receive escalating doses of DCSZ11 and a fixed dose of pembrolizumab until DCSZ11 doses for phase 1b are selected:

  • Phase 1a DCSZ11 monotherapy Dose Escalation.
  • Phase 1a DCSZ11 in combination with fixed dose of pembrolizumab Dose Escalation.

Once Phase 1b doses are selected for Phase 1b, participants of select advanced or metastatic solid cancers will receive DCSZ11 in below defined cohorts in Phase 1b:

  • Phase 1b cohort 1 non-small cell lung cancer (NSCLC).
  • Phase 1b cohort 2 Microsatellite Stable Colorectal Cancer (MSS-CRC) without liver involvement.
  • Phase 1b cohort 3 MSS-CRC with liver involvement.

DCSZ11 will be administered as a single intravenous (IV) infusion on Day 1 in each 21-day cycle. Pembrolizumab will be given as an injection.

The overall time to participats in this study is 60 months. Participants will make multiple visits to the clinic, and survival follow-up for a maximum of up to 12 months after the last dose of the study drug.

Conditions

This trial is treating patients with advanced solid cancers that have progressed on or after standard therapy, or for whom there is no effective standard therapy

Scientific Title

A Phase 1, Multicenter, Open-Label, Dose Escalation and Expansion Study to Assess Safety, Tolerability, Pharmacokinetics, Pharmacodynamics of DCSZ11 as a Monotherapy and in Combination in Patients With Advanced or Metastatic Solid Tumors

Eligibility

Inclusion

  1. Male or female patients ≥ 18 years of age.
  2. Have a histologically or cytologically documented, advanced (metastatic and/or unresectable) solid tumor that has progressed on or after standard therapy (relapsed/refractory patients; patients must have failed at least one prior line of therapy) or for whom there is no effective standard therapy based on the Investigator's judgment.
  3. At least 1 measurable lesion according to RECIST Version 1.1.
  4. Patients must have a lesion that can be biopsied with acceptable clinical risk and agree to have a biopsy at Screening and on treatment.
  5. Eastern Cooperative Oncology Group (ECOG) performance status 0 to 2.
  6. Adequate organ function and bone marrow reserve as indicated by the following laboratory assessments performed within 14 days prior to the first dose of study drug.
  7. For female patients of childbearing potential must have a negative serum beta-human chorionic gonadotropin (β-hCG) pregnancy test and agree to use highly effective contraception.
  8. For men who are not surgically sterile must agree to remain abstinent (refrain from heterosexual intercourse) or use contraception, and agreement to refrain from donating sperm.
  9. The patient is capable of understanding and complying with the protocol and has signed the required ICF. The appropriate ICF must be signed before relevant study procedures are performed. If applicable, the female partner of a male patient understands and signs the pregnant partner's ICF.

Exclusion

  1. Received systemic anticancer treatments or investigational products within 14 days before the first dose of the study drug or 5 half-lives, whichever is shorter.
  2. Received extended field radiotherapy ≤4 weeks before the start of treatment (≤7 days for limited field radiation for palliation outside the chest or brain).
  3. Patients with second malignancy within the previous 3 years, except treated basal cell or localized squamous skin carcinomas, localized prostate cancer, cervical carcinoma in situ, resected colorectal adenomatous polyps, breast cancer in situ, or other malignancy for which the patient is not on active anticancer therapy.
  4. Systemic arterial thrombotic or embolic events, such as cerebrovascular accident (including ischemic attacks) or hemoptysis within 3 months prior to the first dose of study drug.
  5. Systemic venous thrombotic events (eg, deep vein thrombosis) or pulmonary arterial events (eg, 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.
  6. Left ventricular ejection fraction (LVEF) < 50%
  7. 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.
  8. Marked proteinuria ≥ 2 g/24 hours and/or nephrotic syndrome. Patients with proteinuria 2+ or greater urine dipstick reading should undergo further assessment, eg, a 24-hour urine collection.
  9. For patients receiving a combination with pembrolizumab:

    1. History of adverse events related to immunotherapy that required treatment discontinuation.
    2. History of autoimmune disease requiring systemic immunosuppressive therapy with daily doses of prednisone >10 mg/day or equivalent doses, or any other form of immunosuppressive therapy. 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.
    3. History of noninfectious pneumonitis that required steroids or a history of interstitial lung disease.
    4. Evidence of active, noninfectious pneumonitis.
    5. History of allogeneic tissue or solid organ transplant.
  10. 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.
  11. Psychiatric illness/social circumstances that would limit compliance with study requirements and substantially increase the risk of AEs or has compromised ability to provide written informed consent.
  12. Female patients who are pregnant or lactating and breastfeeding.
