ApprovedADC
Enfortumab vedotin · Padcev

Enfortumab vedotin is an ADC against Nectin-4 that, combined with pembrolizumab, nearly doubled survival in advanced bladder cancer.

ApprovedADC
Brentuximab vedotin · Adcetris

The ADC that made the modern field credible (2011), for Hodgkin lymphoma and CD30+ lymphomas.

ApprovedADC
Tisotumab vedotin · Tivdak

Tisotumab vedotin is an ADC against tissue factor, the first to show a survival benefit in recurrent cervical cancer.

ApprovedSmall-molecule kinase inhibitor (HER2)
Tucatinib · Tukysa

A HER2-selective pill that works in the brain, for HER2-positive breast cancer with brain metastases.

Not filedADC
Disitamab vedotin

Disitamab vedotin is a Chinese HER2 ADC approved for gastric and bladder cancer, now in global trials with Pfizer.

ApprovedSmall-molecule CDK4/6 inhibitor
Palbociclib · Ibrance

Palbociclib was the first CDK4/6 inhibitor (2015), and in 2026 became the first approved as maintenance in HER2-positive, hormone-positive breast cancer.

ApprovedSmall-molecule kinase inhibitor (ALK/ROS1)
Lorlatinib · Lorbrena

An ALK inhibitor with the longest disease control ever recorded for a targeted lung cancer pill: 60% progression-free at five years.

ApprovedSmall-molecule kinase inhibitor (BRAF)
Encorafenib · Braftovi

Encorafenib is a BRAF inhibitor that, with cetuximab and chemotherapy, became first-line standard for BRAF-mutant colorectal cancer in 2026.

ApprovedSmall-molecule PARP inhibitor
Talazoparib · Talzenna

Talazoparib is the most potent PARP trapper, approved in BRCA breast cancer and with enzalutamide in prostate cancer.

ApprovedPROTAC oestrogen receptor degrader
Vepdegestrant · Veppanu

Vepdegestrant is the first PROTAC ever approved (2026): a pill that tags the oestrogen receptor for destruction, for breast cancers with ESR1 mutations.

ApprovedADC
Gemtuzumab ozogamicin · Mylotarg

Gemtuzumab ozogamicin (Mylotarg) was the very first ADC: approved in 2000, withdrawn in 2010 for toxicity, and re-approved in 2017 at a lower fractionated dose. Its history is cautionary and instructive.

Phase 3Small-molecule CDK4-selective inhibitor
Atirmociclib

A next-generation pill that blocks only CDK4, not CDK6, to keep the benefit of today's drugs without the low blood counts.

ApprovedMonoclonal antibody (anti-PD-L1)
Avelumab · Bavencio

Avelumab is a PD-L1 blocker given as maintenance after chemotherapy for advanced bladder cancer, which lengthened survival by about seven months.

ApprovedSmall-molecule kinase inhibitor (VEGFR)
Axitinib · Inlyta

Axitinib is a selective VEGF-receptor pill, now given mainly with pembrolizumab or avelumab as first-line kidney cancer treatment.

ApprovedSmall-molecule kinase inhibitor (MEK1/2)
Binimetinib · Mektovi

Binimetinib is the MEK inhibitor partnered with encorafenib; blocking the next step in the same relay stops the tumour rerouting around the BRAF block.

Not mapped hereSmall-molecule BCR-ABL1/SRC TKI
Bosutinib · Bosulif

Bosutinib is a CML pill with less cardiovascular and pleural toxicity than its rivals; its main side effect is diarrhoea.

Not mapped hereSmall-molecule ALK/ROS1/MET TKI (first generation)
Crizotinib · Xalkori

Crizotinib was the first ALK inhibitor, approved four years after ALK fusions were found in lung cancer; it was also the first drug for ROS1 lung cancer and for ALK-positive lymphoma and inflammatory myofibroblastic tumour in children.

Not mapped hereSmall-molecule pan-ErbB TKI (second generation, irreversible)
Dacomitinib · Vizimpro

A second-generation EGFR pill that beat gefitinib on survival in EGFR-mutant lung cancer but was quickly overshadowed by osimertinib.

ApprovedBispecific T-cell engager (BCMA×CD3)
Elranatamab · Elrexfio

Elranatamab is Pfizer's BCMA bispecific, given under the skin every week then every two weeks, for myeloma after four prior lines.

ApprovedSmall-molecule AR antagonist
Enzalutamide · Xtandi

The most widely used androgen-receptor blocker, approved across every stage of advanced prostate cancer, including rising PSA after surgery.

Not mapped hereSmall-molecule smoothened (hedgehog) inhibitor
Glasdegib · Daurismo

Glasdegib is a hedgehog-pathway pill that, with low-dose chemotherapy, extends survival in older AML patients who cannot have intensive treatment; it has largely been displaced by venetoclax combinations.

ApprovedADC
Inotuzumab ozogamicin · Besponsa

Inotuzumab ozogamicin is an antibody carrying a DNA-cutting toxin to CD22 on leukaemia cells. It gets far more relapsed ALL patients into remission than chemotherapy and bridges them to transplant.

Not mapped hereTopoisomerase I inhibitor (camptothecin prodrug)
Irinotecan (and liposomal irinotecan) · Camptosar / Onivyde

Irinotecan is a topoisomerase-blocking chemotherapy central to bowel and pancreatic cancer regimens (FOLFIRI, FOLFIRINOX, NALIRIFOX) and to salvage therapy in childhood sarcomas; it carries the same warhead as the deruxtecan ADC payloads.

Phase 3Small-molecule EZH2 inhibitor
Mevrometostat

An epigenetic drug that may re-sensitise prostate cancer to hormone therapy, in three phase 3 trials with enzalutamide.

ApprovedSmall-molecule multi-kinase inhibitor (VEGFR, PDGFR, KIT)
Sunitinib · Sutent

Sunitinib is an anti-angiogenic pill approved for pancreatic neuroendocrine tumours, kidney cancer and GIST.

Not mapped hereIntravenous mTOR inhibitor (rapamycin analogue)
Temsirolimus · Torisel

A weekly infusion that was the first drug to extend survival in poor-risk kidney cancer (2007), and in 2024 the first targeted drug to improve outcomes in childhood rhabdomyosarcoma.

BREAKWATER: encorafenib plus cetuximab with chemotherapy as first treatment for BRAF V600E-mutated colorectal cancer

Patients with newly diagnosed metastatic colorectal cancer whose tumour carries a BRAF V600E mutation, which is about 8-12% of cases, should now be offered encorafenib and cetuximab together with FOLFOX from the start rather than after chemotherapy fails; median survival has roughly doubled to about two and a half years. BRAF testing at diagnosis is therefore essential, alongside RAS and mismatch repair testing. The regimen is more toxic than chemotherapy alone.

EV-302: enfortumab vedotin plus pembrolizumab replaces chemotherapy as first treatment for advanced bladder cancer

Almost every patient newly diagnosed with advanced bladder or urothelial cancer should now be offered enfortumab vedotin plus pembrolizumab rather than chemotherapy, with median survival extended from about 16 months to over two and a half years. Neuropathy and skin toxicity need monitoring and dose adjustment, and patients with severe diabetes or pre-existing neuropathy need care. Platinum chemotherapy remains an option for those who cannot receive the combination.

MagnetisMM-3: elranatamab, a second BCMA bispecific, with a switch to fortnightly dosing after response

Elranatamab confirmed that BCMA bispecifics are a class, not a one-off, and its protocol-built dose reduction after response set a precedent for lowering the immunosuppressive burden of T-cell engagers. Patients now have two approved BCMA bispecifics and one against GPRC5D (talquetamab). Choosing between them, and sequencing them with CAR-T, remains guided by availability and toxicity profile rather than head-to-head data.

CROWN: lorlatinib versus crizotinib as first treatment for ALK-positive lung cancer

For ALK-positive advanced lung cancer, lorlatinib as the first drug offers the possibility of many years without progression and strong protection against brain metastases. Alectinib and brigatinib remain alternatives with a gentler side-effect profile; the choice weighs lorlatinib's cognitive, metabolic and weight effects against its unmatched duration of control.

ECHELON-1: brentuximab vedotin replacing bleomycin in first-line chemotherapy for advanced Hodgkin lymphoma

ECHELON-1 made a targeted antibody-drug conjugate part of first-line Hodgkin therapy and eventually showed that this saves lives, not just relapses. It set the reference arm against which nivolumab-AVD (SWOG S1826) and BrECADD (HD21) were later compared. Neuropathy is the main price and needs proactive dose modification.

INO-VATE: inotuzumab ozogamicin, a CD22 antibody-drug conjugate, versus chemotherapy for relapsed adult B-cell ALL

INO-VATE made inotuzumab a standard salvage therapy for adult ALL and a common route to transplant, and, with the TOWER trial of blinatumomab, moved adult ALL from chemotherapy-only salvage to immunotherapy. Both drugs have since been pulled into front-line regimens. The liver toxicity signal shaped how transplant conditioning is chosen after inotuzumab.
