Phase I Trial of AEG35156 an Antisense Oligonucleotide to XIAP Plus Gemcitabine in Patients With Metastatic Pancreatic Ductal Adenocarcinoma
Bibliographic record
Abstract
OBJECTIVES: AEG35156 is an antisense oligonucleotide (ASO) that targets the X-linked inhibitor of apoptosis mRNA. Preclinical studies showed potent activity of AEG35156 in combination with gemcitabine in pancreatic ductal adenocarcinoma (PDA). A phase I study was conducted to establish the maximum-tolerated dose, safety, and antitumor activity of AEG35156 plus gemcitabine in metastatic PDA. METHODS: Fourteen patients with metastatic PDA were enrolled. Nine patients were treated at 350 mg IV and 5 patients at 500 mg IV of AEG35156, 3 weeks on/1 week off of a 28-day cycle. Gemcitabine was administered at 1000 mg/m(2) IV over 30 minutes immediately after AEG35156 in both groups. Because of perceived neurotoxicity dose deescalation to 350 mg was recommended. RESULTS: All 14 patients were evaluable for tolerability and toxicity. Toxicities include neutropenia (grade 3/4, 6 patients), thrombocytopenia (grade 3, 2 patients), peripheral neuropathy (grade 3, 2 patients), fatigue (grade 3, 4 patients), ascites (grade 3, 2 patients), and nausea/vomiting (grade 4, 2 patients). Five patients (45%) experienced stable disease with a median progression-free survival of 58 days (95% CI, 52-107 d). CONCLUSIONS: The maximum-tolerated dose is AEG35156 500 mg plus gemcitabine 1000 mg/m(2) given on days 1, 8, and 15 every 28 days. AEG35156 plus gemcitabine failed to show significant clinical activity in advanced PDA.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
