| Step | Treatment / Action | Timing | Status | Rationale |
|---|---|---|---|---|
| STEP 1 | Switch Phenytoin → Levetiracetam (Keppra) | Immediately — BEFORE any cancer therapy | URGENT | Phenytoin is a strong CYP3A4 inducer — reduces ivosidenib plasma levels by 60-80%. Keppra has no CYP3A4 interaction. Tibsovo Label → |
| STEP 2 | Y-90 Radioembolization (SIRT) | BEFORE Ivosidenib — timing critical | TIME-SENSITIVE | IDH1-mutant tumors are 1.4-1.8x more radiosensitive (2-HG → BRCAness). Ivosidenib REVERSES this. Y-90 must happen before Ivo. Lu et al. 2021 → |
| STEP 3 | Ivosidenib + Durvalumab + GemCis (Triple) | 1st-line combination — after Y-90 | FDA-APPROVED | Ivo blocks IDH1 → tumor becomes immunologically “hot”. Durvalumab (anti-PD-L1) exploits this. GemCis as cytotoxic backbone. ClarIDHy Ivo mono: mPFS 2.7mo. TOPAZ-1 Durva+GemCis: mOS 12.8mo. ClarIDHy → TOPAZ-1 → |
| STEP 4 | QTc Monitoring Protocol | Ongoing with Ivosidenib | MANDATORY | ECG: Baseline → Day 14 → monthly x3 → quarterly. QTcF >500ms → hold Ivo. Avoid Ondansetron (use Granisetron). Magnesium 200-400mg/d mandatory. |
| STEP 5 | Olaparib (PARP) — BRCAness | After Ivo response confirmed | OFF-LABEL | IDH1 → 2-HG → HR deficiency (BRCAness). Olaparib exploits this without BRCA mutation. IDH1-BRCAness → |
| RESISTANCE | Olutasidenib (Rezlidhia) | On Ivo resistance (D279N) | FDA (AML) | Overcomes D279N resistance mutation. ORR 42.1% in IDH1-mutant AML. Olutasidenib → |
| MONITOR | NCT07006688 — Ivo PK hepatic impairment | Recruiting | Phase 1 | Relevant for F4 cirrhosis. ClarIDHy excluded Child-Pugh B/C. Trial → |
| MONITOR | NCT06707493 — Ivo maintenance | Recruiting | Phase 2 | Ivo maintenance after 1st-line. Could change standard-of-care. Trial → |
| RESEARCH | mRNA Neoantigen Vaccine (R132C) | Research | EXPERIMENTAL | NOA-16: R132H vaccine 93.3% T-cell response. R132C needs custom design. NOA-16 → OpenVAXX → |

Evidence Convergence
COMPUTATIONALMulti-dimensional evidence convergence scoring across thousands of curated, quality-filtered claims extracted from 6,400+ PubMed sources. Each of the 58 molecular targets is scored across five independent dimensions: Claim Volume (raw evidence mass — how many distinct assertions support this target), Lab Independence (number of unique research groups reporting findings — guards against single-lab bias), Method Diversity (range of experimental approaches: in vitro, animal model, patient data, computational — cross-validated findings score higher), Temporal Trend (whether evidence is growing, stable, or declining over recent years — captures scientific momentum), and Replication (how often key findings have been independently confirmed across different studies and model systems). Scores are weighted and combined into a composite convergence score (0–100). All weights and methodology are fully transparent and transparent methodology. The engine generates falsifiable predictions grounded in evidence — each prediction card links every supporting claim back to its source paper for full traceability.
Prediction Cards
Evidence Calibration
COMPUTATIONALBayesian back-testing of convergence scores against known drug outcomes — the critical self-check that separates rigorous research from speculation. For each drug with a known clinical outcome (approved, failed in Phase 2/3, or preclinical only), the platform asks: did our evidence scoring predict the right outcome? The calibration process works as follows: (1) Outcome collection — gather real-world drug approval/failure data from ClinicalTrials.gov and FDA records for all 21 tracked drugs. (2) Score comparison — compare each drug's convergence score against its actual clinical outcome. Approved drugs (ivosidenib, gemcitabine+cisplatin, pemigatinib) should score high; failed drugs should score low. (3) Bayesian updating — use the comparison to compute posterior probabilities, measuring how well evidence mass predicts clinical success. (4) Grade assignment — the system earns a calibration grade (A–F) based on concordance between predicted and actual outcomes. Grade A (current: 89.8%) means the scoring reliably separates successful from unsuccessful therapeutic approaches. A well-calibrated platform means researchers can trust the convergence scores when evaluating novel, untested targets.

About IDH1-iCCA
Frequently asked questions about IDH1-mutant cholangiocarcinoma and this research platform.
What is IDH1-Mutant Cholangiocarcinoma (iCCA)?
IDH1-mutant intrahepatic cholangiocarcinoma (iCCA) is a bile duct cancer driven by gain-of-function mutations in the IDH1 gene (most commonly R132C, accounting for 77% of cases). The mutant enzyme produces the oncometabolite 2-hydroxyglutarate (2-HG), which drives epigenetic dysregulation, DNA repair impairment (BRCAness), and immune suppression. Ivosidenib (Tibsovo) is the first targeted therapy approved for IDH1-mutant cholangiocarcinoma.
What approved treatments exist for IDH1-iCCA?
Key therapies for IDH1-iCCA include: Ivosidenib (Tibsovo) — a targeted oral IDH1 inhibitor, FDA-approved 2021 for previously treated IDH1-mutant CCA (ClarIDHy trial). Gemcitabine + Cisplatin — standard first-line chemotherapy for advanced biliary tract cancer. Durvalumab + GemCis — immune checkpoint inhibitor plus chemotherapy, FDA-approved 2022 (TOPAZ-1 trial). Pipeline agents include FGFR2 inhibitors, PARP inhibitors, and IDH1 vaccines.
What is the IDH1-iCCA Research Platform?
The IDH1-iCCA Research Platform is an evidence-first drug research platform that aggregates, structures, and prioritizes global IDH1-iCCA evidence automatically. It ingests data from PubMed, ClinicalTrials.gov, STRING-DB, and KEGG. It uses LLM-based claim extraction to identify thousands of structured claims from abstracts, scores 21 molecular targets across 7 dimensions, and prioritizes hundreds of hypotheses into action tiers for accelerating therapeutic development.
What are the key molecular targets for IDH1-iCCA?
Primary oncology targets: IDH1 (causally mutated oncogene), IDH2, FGFR2 (co-altered in ~15% of iCCA), TP53, ARID1A, BAP1 (chromatin remodeling). Druggable pathway targets: mTOR, VEGFA (angiogenesis), ERBB2 (HER2), BRAF, KRAS, PIK3CA, MET, PDGFRA. Each target is scored on evidence depth, druggability, and clinical validation.
How does the hypothesis prioritization work?
Hypotheses are scored across 5 dimensions: evidence depth (claim count and LLM confidence, 25% weight), source convergence (independent papers, 20%), therapeutic clarity (clear modality suggestion, 20%), target strength (parent target's composite score, 20%), and novelty (emerging vs well-trodden research angles, 15%). The top 5 are assigned Tier A (high-conviction, ready for computational drug design), ranks 6-15 get Tier B (need more evidence), and the rest get Tier C.
Drug Screening
COMPUTATIONAL
This pipeline computationally filters thousands of ChEMBL compounds down to the best candidates for IDH1-iCCA drug discovery. The process runs in six steps: (1) ChEMBL query — compounds bioactive against top-scored IDH1-iCCA targets are fetched with their SMILES strings; (2) RDKit descriptor calculation — molecular weight, LogP, rotatable bonds, H-bond donors/acceptors, TPSA, and QED are computed from SMILES; (3) Lipinski Rule of 5 — MW < 500, LogP < 5, HBD ≤ 5, HBA ≤ 10; compounds failing two or more rules are flagged as non-drug-like; (4) Hepatic bioavailability estimate — TPSA and MW thresholds are used as heuristics for oral absorption and hepatic distribution (note: BBB penetration is not required for liver cancer); (5) Drug-likeness MPO score — a 0–6 composite of LogP, LogD, MW, TPSA, HBD, and pKa tuned for oncology drug development; (6) PAINS filter — substructure alerts for pan-assay interference compounds that cause false positives in biochemical screens.
Drug delivery considerations for IDH1-iCCA: Intrahepatic cholangiocarcinoma is located within the liver — where drugs must achieve adequate hepatic concentrations. Unlike CNS tumors, BBB penetration is not a barrier. However, liver-first-pass metabolism and CYP3A4 interactions are critical considerations. Ivosidenib has good oral bioavailability but is extensively metabolized by CYP3A4. Compounds must achieve adequate hepatic concentrations through portal blood flow and avoid excessive CYP3A4 metabolism.
Score glossary: Lipinski — binary pass/fail for oral bioavailability potential. Hepatic Bioavail. — heuristic estimate of hepatic distribution (TPSA + MW; note: BBB is not critical for liver cancer). Drug-likeness MPO — 0–6 score; ≥ 4 is considered drug-optimized. QED — 0–1 drug-likeness estimate combining eight Lipinski-adjacent properties; ≥ 0.5 is high quality. PAINS — substructure alert for reactive or promiscuous scaffolds that should be deprioritized.
Note: Drug-likeness predictions use rule-based heuristics (Lipinski Rule of 5, TPSA-based bioavailability estimate, QED score). These are filtering tools, not validated PK/tox models.

Drug Repurposing
COMPUTATIONAL
Drug repurposing means finding new therapeutic uses for existing approved drugs — bypassing the 10–15 years and $1–2B typically required for de novo drug development. Repurposed drugs have already passed safety trials, so clinical translation is dramatically faster: Phase I is often skipped and Phase II can start in 2–3 years rather than 10+.
The platform identifies IDH1-iCCA treatment candidates through three convergent strategies: (1) Cross-disease mining — drugs approved or in trials for related IDH1-mutant cancers (glioma, AML) that share molecular targets with IDH1-iCCA; (2) ChEMBL bioactivity — known compounds with high pChEMBL values (≥ 6.0, corresponding to IC₅₀ ≤ 1 µM) against top-scored IDH1-iCCA targets; (3) Pathway overlap — compounds whose known mechanism overlaps with the metabolic, DNA repair, or immune pathways dysregulated in IDH1-iCCA.
Precedent in IDH1-iCCA: Olaparib, originally a BRCA-mutant cancer drug, shows efficacy in IDH1-mutant CCA through BRCAness — its exploitation of the BRCAness phenotype created by 2-HG enables tumor-selective killing. Erlotinib showed benefit in a subset of BTC patients. Bevacizumab combined with GemCis is being evaluated in clinical trials. The platform extends this approach computationally, scoring each candidate 0–1 based on target relevance, potency, clinical phase, and pathway convergence.

Top Drug Candidates
COMPUTATIONAL
In drug discovery, a hit is a compound that shows measurable activity against a target of interest and passes initial computational filters. This section is the unified ranked list — the best compounds from all analysis pipelines: ChEMBL screening, cross-disease repurposing, and DiffDock virtual binding.
Each candidate passes through a 6-stage validation pipeline: (1) Computational — drug-likeness filters (Lipinski, QED, PAINS), hepatic bioavailability scoring; (2) Structural — DiffDock pose prediction against IDH1-iCCA target binding pockets, confidence scoring; (3) Analog search — ChEMBL SAR analysis to identify structurally similar compounds with known IDH1-iCCA-relevant activity; (4) ADMET prediction — rule-based absorption, distribution, metabolism, excretion, and toxicity estimates; (5) Literature review — automated PubMed search for the compound + IDH1-iCCA target co-occurrence; (6) Experimental design — suggested assay types (2-HG measurement, cell viability, immune markers) for validation.
Candidates are scored 0–1 (integrated score) and assigned a tier: Tier A (≥ 0.6) — strong multi-dimensional evidence, prioritized for experimental follow-up; Tier B (0.4–0.6) — moderate evidence, worth secondary screening; Tier C (< 0.4) — computational-only signal, lower priority. Click any row to see full molecular properties, hepatic bioavailability, DiffDock score, validation stage, and target link.

Cross-Species Comparative
COMPUTATIONALCross-species conservation mapping of IDH1-iCCA-relevant molecular targets across 7 model organisms. Each organism offers unique advantages for IDH1-iCCA research: mice (Mus musculus) serve as the primary disease model for IDH1-mutant cholangiocarcinoma (patient-derived xenografts and genetically engineered models); zebrafish (Danio rerio) enable rapid drug screening with IDH1-mutant liver models; the rat (Rattus norvegicus) provides orthotopic iCCA models. Conservation scores are computed from NCBI Ortholog data — a score of 71% or higher indicates strong evolutionary conservation, suggesting the target's function is preserved across species and findings from model organisms are likely translatable to humans.

Protein Structures
STRUCTURALPredicted 3D structures for all IDH1-iCCA research targets using AlphaFold2, ESMfold, and Boltz-2. Each structure is scored by pLDDT (predicted Local Distance Difference Test) — a per-residue confidence metric that tells you how reliable each part of the structure is for drug design.
Structures predicted via AlphaFold DB v6 (EMBL-EBI), ESMfold v1, and Boltz-2 (Chai Discovery). Method badges indicate prediction source. pLDDT scores from predicted structures. MW estimates: ~110 Da per residue. Pre-existing PDB structures retain original experimental resolution.

Druggable Pockets
STRUCTURALP2Rank-predicted binding pockets across IDH1-iCCA target protein structures. Identifies the cavities on protein surfaces where small molecules can bind — the first step in structure-based drug design.
20-50 = Moderate cavity, may require fragment-based approaches
<20 = Shallow or solvent-exposed, poor drug target
0.5-0.8 Possible target, needs optimized ligand design
<0.5 This pocket is too shallow or exposed for standard drugs
Pocket predictions via P2Rank 2.5.1 with AlphaFold-optimized configuration. Druggable flag requires score > 50 AND probability > 0.8. SAS points = Solvent Accessible Surface connolly dots defining pocket boundary.

Cross-Paper Synthesis
COMPUTATIONALNon-obvious connections across thousands of curated claims from different papers — the platform's core differentiator. While individual papers report isolated findings, cross-paper synthesis reveals hidden patterns: targets that co-occur in unrelated studies, shared mechanisms between seemingly independent pathways, and transitive bridges (if Paper A links X→Y and Paper B links Y→Z, the platform discovers X→Z). The analysis builds a co-occurrence matrix across all claims, identifies statistically significant target pairs, and generates synthesis cards that explain the biological connection with full citation trails. This is how the platform discovered the IDH1-2HG-TET2-BRCAness axis as a therapeutic vulnerability — no single paper described the complete pathway, but the synthesis engine connected findings from 12+ independent publications.
