Sponsor: Novartis Pharmaceuticals (industry) Phase: 1 Start date: Oct. 16, 2025

TrialFetch AI summary: Adults with DLL3-expressing advanced solid tumors, including previously treated SCLC or LCNEC (dose escalation) and expansion cohorts of SCLC (≤2 prior lines), de novo or treatment-emergent NEPC, and GEP-NEC; some cohorts require demonstrable uptake on 111In-ETN029 SPECT. Single-arm therapy with 225Ac-ETN029, a DLL3-targeted alpha-emitting radiopharmaceutical delivering actinium-225 to tumor cells, with optional 111In-ETN029 imaging/dosimetry.

Sponsor: Amgen (industry) Phase: 1 Start date: Sept. 16, 2025

TrialFetch AI summary: Adults with extensive-stage SCLC that has progressed after ≥1 prior systemic therapy, including those with controlled brain metastases, receive tarlatamab (DLL3-directed bispecific T‑cell engager) combined with AB248 (CD8-targeted IL‑2 mutein fusion designed to selectively activate CD8+ T cells) to assess safety, dose, and preliminary efficacy. Excludes prior DLL3- or IL‑2/7/15–directed therapies and symptomatic CNS disease.

ClinicalTrials.gov ID: NCT07037758

No known activity More information High burden on patient More information
Sponsor: Molecular Partners AG (industry) Phase: 1/2 Start date: Dec. 12, 2025

TrialFetch AI summary: Adults with locally advanced or metastatic DLL3-expressing tumors—primarily relapsed/refractory SCLC after ≥2 prior systemic lines including platinum and immunotherapy (or not suitable for standard 2L), plus previously treated lung LCNEC and extrapulmonary neuroendocrine carcinomas—are eligible (measurable disease; stable CNS mets allowed), with DLL3 positivity confirmed by [203Pb]Pb-DOTAM-MAM279 SPECT/CT in specified cohorts. Participants receive [203Pb]Pb-DOTAM-MAM279 imaging/dosimetry followed by therapeutic [212Pb]Pb-DOTAM-MAM279 (MP0712), a DLL3-targeted DARPin radiopharmaceutical delivering alpha-emitting lead-212 to DLL3-expressing tumor cells.

ClinicalTrials.gov ID: NCT07278479

No known activity More information High burden on patient More information
Sponsor: Sutro Biopharma, Inc. (industry) Phase: 1 Start date: Nov. 7, 2025

TrialFetch AI summary: Adults (ECOG 0–1) with refractory/recurrent locally advanced or metastatic solid tumors—particularly tissue factor–expressing cancers such as HNSCC, NSCLC, esophagogastric, colorectal, pancreatic ductal adenocarcinoma, cervical, endometrial, or urothelial carcinoma—after appropriate prior systemic therapy (prior-line limits vary by study part) are eligible. Treatment is STRO-004, a tissue factor–targeting antibody–drug conjugate delivering an exatecan (topoisomerase I inhibitor) payload, given as monotherapy with dose escalation/expansion or combined with pembrolizumab (PD-1 inhibitor).

ClinicalTrials.gov ID: NCT07227168

No known activity More information High burden on patient More information
Sponsor: Plexium, Inc. (industry) Phase: 1 Start date: Dec. 16, 2025

TrialFetch AI summary: Enrolls adults with relapsed/refractory locally advanced or metastatic solid tumors harboring a SMARCA4 loss-of-function mutation (ECOG 0–1, measurable disease) after progression on, intolerance of, or ineligibility for standard approved therapies. Patients receive oral once-daily PLX-61639, a SMARCA2 targeted protein degrader (synthetic-lethal strategy in SMARCA4-deficient tumors; DCAF16-linked, proteasome-mediated SMARCA2 degradation).

ClinicalTrials.gov ID: NCT07284186

No known activity More information High burden on patient More information
Sponsor: Sairopa B.V. (industry) Phase: 1 Start date: April 3, 2023

TrialFetch AI summary: Enrolling adults (ECOG 0–1) with metastatic/unresectable solid tumors refractory to standard therapy (excluding melanoma, primary brain tumors/GBM, sarcoma, and pancreatic ductal adenocarcinoma; no active untreated brain mets), with expansion cohorts limited to ≤3 prior systemic lines and focused on PD-(L)1–naïve MSS colorectal cancer without liver metastases and PD-1 relapsed/refractory MSS endometrial cancer, RCC, or NSCLC. Patients receive IV ADU-1805 (anti-SIRPα mAb blocking the SIRPα–CD47 “don’t eat me” checkpoint to enhance myeloid/macrophage activity) every 3 weeks alone or with fixed-dose pembrolizumab every 3 weeks.

ClinicalTrials.gov ID: NCT05856981

No known activity More information High burden on patient More information
Sponsor: Bristol-Myers Squibb (industry) Phase: 1/2 Start date: Nov. 25, 2025

TrialFetch AI summary: Adults with locally advanced unresectable or metastatic solid tumors harboring a KRAS alteration (mutation or amplification) who have progressed on, are ineligible for, or declined standard-of-care therapy (Arm D additionally requires PD-L1 TPS ≥50%; excludes untreated CNS metastases and ILD/pneumonitis). Participants receive the first-in-human agent BMS-986523 (target/mechanism not publicly described) as monotherapy or combined with pembrolizumab (anti–PD-1), cetuximab (anti-EGFR), or gemcitabine plus nab-paclitaxel.

ClinicalTrials.gov ID: NCT07223047

No known activity More information High burden on patient More information
Sponsor: PAQ Therapeutics, Inc. (industry) Phase: 1 Start date: Nov. 21, 2025

TrialFetch AI summary: Adults with locally advanced/metastatic measurable solid tumors harboring any KRAS mutation or wild-type KRAS amplification (ECOG 0–1) after 1–4 prior systemic regimens are treated with IV PT0511 monotherapy in dose-escalation/expansion cohorts; a colorectal cancer expansion cohort receives PT0511 plus cetuximab (anti-EGFR). PT0511 is an investigational KRAS-altered tumor–directed agent, but its specific molecular mechanism/allele selectivity is not publicly specified.

ClinicalTrials.gov ID: NCT07300150

Treatment is continued osimertinib plus escalating-dose oral NXP900 (eCF506), a selective SRC-family kinase inhibitor (high potency vs YES1; also SRC) designed to lock kinases in an inactive conformation to address resistance biology.
