About this trial
This is Phase 1/2, multicenter, clinical study to evaluate the safety, efficacy, PK, and immunogenicity of IDE849 in subjects with DLL3-expressing tumors including SCLC.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Are willing to participate in this clinical study, understand the study procedures, and are able to sign the written ICF.
Subjects with histologically or cytologically confirmed ES- SCLC, neuroendocrine carcinoma (NEC), DLL3+ solid tumors, are eligible per protocol. Subjects must have radiologically progressed or recurred after previous standard treatment.
Subjects with NEC, this includes
High-grade gastroenteropancreatic NEC
Disqualifiers
Have mixed SCLC and NSCLC histology are not allowed (SCLC with components of large cell NEC are eligible). Participants with limited stage SCLC are ineligible.
Subjects with locally untreated (radiotherapy or surgery) or active central nervous system (CNS) tumor metastasis.
Have had other malignancies within 2 years prior to the first dose, except adequately treated carcinoma in situ (cervical, breast, or other), basal cell or squamous cell skin cancer, localized prostate cancer after curative therapy with no recurrence, or papillary thyroid cancer after curative resection; other prior or concurrent malignancies may be eligible with Medical Monitor review and approval.
Have uncontrolled tumor-associated pain.

Trial outcomes
Primary outcomes
Part 1A: Safety and Tolerability of IDE849 (Monotherapy)
Incidence of dose-limiting toxicities, incidence and severity AEs and SAEs as measured by CTCAE V5.0.
Part 1B: Safety and Tolerability of IDE849 in Combination with durvalumab or IDE161
Incidence of dose-limiting toxicities, incidence and severity AEs and SAEs as measured by CTCAE V5.0.
Part 2: Safety and Tolerability of IDE849 (Monotherapy Dose Expansion)
Incidence and severity and relationship of AEs and SAEs as measured by CTCAE V5.0
Part 2: Safety and Tolerability of IDE849 in Combination with durvalumab or IDE161 or durvalumab + carboplatin (Dose Expansion)
Incidence and severity and relationship of AEs and SAEs graded as measured by CTCAE V 5.0.
Secondary outcomes
Part 1 and Part 2: Disease Control Rate (DCR) and Investigator Assessment of IDE849 DCR per RECIST 1.
Part 2: Progression-Free Survival (PFS) PFS per RECIST1.1 PFS per RECIST1.1.
Part 2: Overall Survival (OS)
Overall Survival (OS) defined as the time from first dose of IDE849 to death due to any cause
Part 1 and Part 2: Pharmacokinetics (PK) of IDE849 and in combination with durvalumab, durvalumab + carboplatin, and IDE161 Blood concentrations and PK parameters.
