Key facts

Disease & market context

Breast Cancer

310K US cases/yr · $35.0B Global breast cancer therapeutics

Disease Overview

Breast cancer is the most common cancer in women worldwide. Treatment is guided by molecular subtype: HR+/HER2-, HER2+, and triple-negative. CDK4/6 inhibitors have transformed HR+ metastatic disease, and ADCs are reshaping later-line treatment.

Standard of Care & Competitive Landscape

HR+/HER2-: CDK4/6 inhibitor + endocrine therapy. HER2+: trastuzumab + pertuzumab + chemo, T-DXd in 2L+. TNBC: pembrolizumab + chemo. Key players: Pfizer (Ibrance), Lilly (Verzenio), Novartis (Kisqali), Daiichi Sankyo/AZ (Enhertu), Gilead (Trodelvy).

Prostate Cancer

300K US cases/yr · $18.0B Global prostate cancer therapeutics

Disease Overview

5-year relative survival ~97.9% overall; ~37.9% for distant (metastatic) disease per SEER 2015-2021.

Standard of Care & Competitive Landscape

Localized: surgery, radiation, active surveillance. mHSPC: ADT + abiraterone or enzalutamide. mCRPC: abiraterone, enzalutamide, PARP inhibitors, Lu-177 PSMA. Key players: J&J (Erleada, Zytiga), Pfizer (Xtandi), AZ (Lynparza), Novartis (Pluvicto), Bayer (Nubeqa).

NSCLC

200K US cases/yr · $30.0B Global NSCLC therapeutics

Disease Overview

Non-small cell lung cancer (NSCLC) is a type of cancer that forms in the tissues of the lung and is the most common form of lung cancer, more prevalent than small cell lung cancer. Its three major histologic subtypes are adenocarcinoma, squamous cell carcinoma (also called epidermoid carcinoma), and large cell carcinoma; less common variants include adenosquamous carcinoma, sarcomatoid carcinoma, salivary gland carcinoma, and carcinoid tumors. NSCLC typically presents with persistent cough, breathing difficulties, chest discomfort, wheezing, blood in sputum, hoarseness, loss of appetite, unexplained weight loss, fatigue, trouble swallowing, or facial swelling, although early-stage disease often causes no signs or symptoms. Smoking is the major risk factor, with additional contributions from secondhand smoke, occupational exposures, radiation, and family history. Because symptoms are frequently absent until the disease is locally advanced or metastatic, many patients are diagnosed at stages at which cure is unlikely, and current treatments do not provide cure for most patients. Management depends on stage and molecular profile and can include surgery, radiation therapy, chemotherapy, targeted therapy, and immunotherapy, with clinical trials offering additional investigational options for patients with non-small cell lung cancer.

Standard of Care & Competitive Landscape

No driver mutation: pembrolizumab +/- chemo. EGFR+: osimertinib. ALK+: alectinib, lorlatinib. KRAS G12C: sotorasib. Key players: Merck (Keytruda $25B+), Roche (Tecentriq), AZ (Tagrisso $5B+, Imfinzi), Pfizer (Lorbrena), Amgen (Lumakras).

Ovarian Cancer

20K US cases/yr · $5.0B Global ovarian cancer therapeutics

Disease Overview

Ovarian cancer is the deadliest gynecologic malignancy. PARP inhibitors have transformed maintenance therapy for BRCA-mutated and HRD-positive disease. Most patients present at advanced stages.

Standard of Care & Competitive Landscape

Surgery + platinum-based chemo. Maintenance: PARP inhibitors (olaparib, niraparib) for HRD+. Bevacizumab in combination. Key players: AZ/Merck (Lynparza), GSK (Zejula), Clovis (Rubraca), Roche (Avastin).
