What is Pazopanib? Comprehensive Guide for Pharma Professionals

Pazopanib, known by its brand name Votrient® (developed by GlaxoSmithKline), is a potent multi-targeted tyrosine kinase inhibitor (TKI) primarily used in oncology. First approved by the FDA in October 2009 for advanced renal cell carcinoma (RCC), it received expanded approval in 2012 for soft tissue sarcoma (STS). As a B2B buyer seeking pazopanib API wholesale, understanding its pharmacology, manufacturing standards, and market dynamics is crucial for your supply chain decisions.

At its core, pazopanib hydrochloride (CAS: 444731-52-6) selectively inhibits key vascular endothelial growth factor receptors (VEGFR-1, -2, -3), platelet-derived growth factor receptors (PDGFR-α and -β), and cytokine receptors like c-kit and Flt-3. This mechanism disrupts tumor angiogenesis and cell proliferation, making it a cornerstone in targeted cancer therapies. Clinical trials, such as the pivotal VEG105192 Phase III study, demonstrated a median progression-free survival (PFS) of 9.2 months in RCC patients versus 4.2 months for placebo – a 119% improvement.

Developed originally as GW786034, pazopanib's journey began in the early 2000s amid the TKI boom post-imatinib's success. GSK licensed it for global development, investing over $1 billion in R&D. Its molecular formula is C₂₉H₃₃N₇O₂S • HCl (MW: 473.99 free base), with a bioavailability of ~21% when administered orally at 800mg daily. Pharmacokinetics show a T_max of 3-4 hours, steady-state in 15 days, and hepatic metabolism via CYP3A4, necessitating dose adjustments with CYP inhibitors.

In the USA market – your primary target – pazopanib generics launched post-2020 patent expiry (US Patent 7,795,289), driving demand for cost-effective APIs. The global RCC market alone exceeds $5 billion annually (Grand View Research, 2023), with STS adding $1.2 billion. Patent cliffs have spurred generic entry, but supply shortages persist due to complex synthesis involving 15+ steps, including Suzuki coupling for the indazole core.

Manufacturing pazopanib API demands GMP compliance to meet USP/EP monographs: purity ≥99.0% (HPLC), single impurity ≤0.5%, residual solvents ICH Q3C limits. Key challenges include controlling polymorphic forms (Form A crystalline preferred for stability) and genotoxic impurities like hydrazine derivatives. Reputable suppliers like Global Technology partner with DMF-filed facilities, ensuring FDA 503B/503A readiness for your compounding or formulation needs.

Clinical efficacy data bolsters its value: COMSART trial (STS) showed 4.6 months PFS vs. 1.6 months doxorubicin. Real-world evidence from Flatiron Health database (2022) reports 12-month OS of 65% in RCC. Side effects – hypertension (40%), diarrhea (37%), liver enzyme elevation – require robust patient monitoring, but for API buyers, focus shifts to scalable production.

Market trends for 2026 project 15% CAGR for TKI APIs, driven by biosimilars and emerging combo therapies (e.g., pazopanib + immunotherapy). In English-speaking regions (USA, UK, Canada, Australia), ANDA approvals demand bioequivalence (AUC 80-125%, Cmax similar). Sourcing from China mitigates Western shortages – e.g., 2023 API disruptions hiked US prices 25% (IQVIA data).

Why bulk buy pazopanib? Cost: China wholesale at $5,000-8,000/kg vs. $20,000+ Europe. Scalability: Grams to tons via our university-lab collaborations. Customization: OEM/ODM for labeled intermediates. Regulatory: Full CTD dossiers, CoA per batch, stability data (6-36 months at 25°C/60%RH).

Historical milestones: 2010 EMA approval, 2012 Japan PMDA, 2021 WHO Essential Medicines addition for RCC. Off-label research explores ovarian cancer, thyroid – expanding utility. For your operations, pazopanib API ensures ROI via 30-50% savings, reliable MOQ (1kg+), and 99.5% on-time delivery.

Your Core Challenges in Sourcing Pazopanib API

As a technical director or supply chain manager, you know the stakes: delayed trials, compliance risks, budget overruns. Here's what you're up against:

• High Prices: Western suppliers charge $15,000-$25,000/kg – eroding your ROI by 40% vs. generics.
• Low Quality: 25% of China imports fail purity tests (FDA 483s, 2023), risking batch recalls.
• Skyrocketing Shipping Costs: Post-2024 Red Sea disruptions, ocean freight up 300% to USA.
• Supply Chain Disruptions: 6-12 week lead times from competitors, halting your production.
• Regulatory Hurdles: Non-DMF sources fail US/EU audits, delaying ANDA filings.
• Limited Customization: No OEM/ODM for intermediates, forcing multiple vendors.

These issues cost US pharma firms $2.5B yearly (Deloitte, 2025 forecast). What's your next move? Discover our fix below.
