Drug Mechanism Heatmaps
Each heatmap shows one class of drugs that work the same way, such as GLP-1 drugs, KRAS inhibitors or antibody-drug conjugates, against every disease the class is being tested in. Rows are drugs and columns are diseases; each cell holds that drug's trials in that disease, taken from ClinicalTrials.gov.
Use them to see which companies lead a class, which diseases are crowded, and which trials read out next. There are 23 classes below, with the most trials first.
IO checkpoint inhibitors
ProPD-1, PD-L1, CTLA-4, LAG-3, TIGIT, TIM-3 antibodies and bispecifics — the most-mature IO landscape.
Antibody-drug conjugates (ADCs)
ProAn antibody-drug conjugate (ADC) is an antibody joined to a potent drug, called the payload.
T-cell engagers (CD3 bispecifics)
ProA T-cell engager is a bispecific antibody: one arm binds CD3 on T cells, the other binds a protein on the target cell, and pulling the two together lets the T cell kill it.
GLP-1 / incretin agonists
ProGLP-1 drugs mimic glucagon-like peptide-1, a hormone the gut releases after a meal.
EGFR family inhibitors
ProEGFR TKIs across generations, exon-20 selective, bispecifics, and EGFR ADCs.
CD19-targeted therapies
ProCD19-directed therapies across modalities (CAR-T, T-cell-engaging bispecifics, mAb/ADC) AND across domains — the heme-oncology workhorse (lymphoma/leukemia) now crossing into autoimmune disease (lupus, myasthenia, scleroderma, myositis), where CD19 CAR-T "resets" the B-cell compartment.
HER2 family
ProHER2 mAbs, ADCs, bispecifics, and small-molecule TKIs.
Immunology bispecifics
ProBispecific antibodies in immunology: dual cytokine blockers that hit two inflammatory pathways at once, and T-cell engagers repurposed to reset the immune system in autoimmune disease.
KRAS family inhibitors
ProKRAS is a gene that works as an on-off switch for cell growth.
JAK / TYK2 inhibitors
ProJAK pan / JAK1 / JAK1/2 / JAK3 / TYK2 inhibitors — the oral kinase backbone across immunology, dermatology, myeloproliferative neoplasms, and (emerging) CNS.
BCMA-targeted therapies
ProBCMA-directed therapies across modalities — CAR-T, T-cell-engaging bispecifics, and ADCs — the dominant target in relapsed/refractory multiple myeloma.
CAR-T cell therapy
ProCAR-T therapy uses a patient's own T cells, a type of immune cell, changed in a lab to carry a chimeric antigen receptor (CAR) that recognizes a protein on the target cells.
Factor XI / XIa inhibitors
ProFactor XI inhibitors are blood thinners (anticoagulants) that block clotting factor XI or its active form, factor XIa.
Trispecific antibodies
ProAntibodies that bind three different targets at once, across cancer and immunology. None is approved yet; a handful are in Phase 3.
PARP / DDR inhibitors
ProPARP inhibitors and broader DNA-damage-response (ATR, WEE1) inhibitors.
Radioligand therapies
ProPSMA / SSTR2 / FAP-targeted radioligand therapies — the fast-emerging precision-oncology modality.
IL-23 axis inhibitors
ProIL-12/23 (p40) and IL-23 (p19) inhibitors — the dominant immunology class for psoriasis, IBD, and emerging.
TL1A inhibitors
ProTL1A is a protein in the TNF family that drives inflammation and scarring (fibrosis) in the gut.
Claudin 18.2 targeting
ProClaudin 18.2 mAbs, ADCs, bispecifics, and CAR-T across gastric and PDAC.
Lp(a) lowering
ProLipoprotein(a), or Lp(a), is a cholesterol-carrying particle in the blood.
mRNA cancer vaccines
PromRNA/saRNA therapeutic cancer vaccines — personalized-neoantigen, shared-antigen, and self-amplifying. V940 (Merck/Moderna) posted the first positive Phase 3 for an mRNA cancer vaccine — the biggest cancer-vaccine readout since sipuleucel-T (2010): INTerpath-001, adjuvant melanoma, met recurrence-free and distant-metastasis-free survival (announced Aug 2026).
MTAP synthetic-lethal inhibitors
ProPRMT5 and MAT2A inhibitors exploiting MTAP-deletion vulnerability — selective oncology synthetic-lethal class.
S1P modulators
ProSphingosine-1-phosphate receptor modulators for UC, MS, and other indications.
