Daxas - awaiting 12-month efficacy data

Ono or Merck expected to launch second-to-market oral PDE-IV inhibitor


CXCR2 antagonists - a focus for GSK, AZ and Schering-Plough?

Restoring the proteinase-antiproteinase balance


Search for disease-modifying therapy continues




CHAPTER 6 ALLERGIC RHINITIS R&D PIPELINE

Novel oral anti-inflammatories: Singulair/PG-D2 combination for allergic rhinitis?


Singulair's status as an asthma drug protects its low co-pay classification

PG-D2 antagonists may address nasal congestion


Novel intranasal non-steroidal therapies


Pfizer has limited option to license Rigel's R-112 for allergic rhinitis

Evolutec's "Tick saliva" - the new antihistamine?

Biolipox's NCX-1510 - the gold standard intranasal antihistamine?


Incremental innovation in established classes


GSK's Allermist US launch most significant near-term event

Novel oral antihistamines struggle to offer differentiation to current market leaders


Xyzal succeeds Zyrtec in US?


Gap in market for improved allergen vaccination technologies

Oral allergen tablets will considerably simplify treatments

Novel "Immunodrug" approaches may have vastly improved delivery schedules




CHAPTER 7 COMPANY PORTFOLIO ANALYSIS

GSK leads in inhaled therapy, but lacks an oral anti-inflammatory

AstraZeneca has a broad early development pipeline in asthma and COPD

Novartis requires partner to be successful in inhaled therapies

Merck's future lies in developing a Singulair/PG-D2 combination product

Pfizer/BI building franchise in COPD around Spiriva combinations

Sanofi-Aventis's pipeline lacks a blockbuster product

Abstract

Introduction
The asthma, COPD and allergic rhinitis global market was $25.5 billion in 2004, with five brands selling over $1.0 billion. While a number of moderately successful launches are expected within the next five years, companies are seeking novel combination therapies to create the next generation of blockbuster drugs.

Scope
  • Evaluation of over 75 drugs in clinical development for asthma, COPD, and allergic rhinitis, including launch forecasts
  • Opinion leader insight into early stage therapies and treatment strategies
  • Forecasts of key late-stage therapies: Alvesco (ciclesonide), Daxas (roflumilast), Xolair (omalizumab), Xopenex (levalbuterol)
  • Forecasted sales of the respiratory market in the next 10 years, exploring the potential impact of early phase therapies
Highlights
Inhaled corticosteroid/long-acting b2-agonist fixed combinations will remain the leading asthma/COPD class in 2015, almost exclusively represented by sales of GSK's "Super Advair", with its once-daily profile setting the new gold standard.

Merck may invigorate the oral asthma market through the development of a Singulair/ prostaglandin-D2 combination product, while monoclonal antibodies will be the fastest growing asthma class, with therapies that are effective in non-atopic asthma having a $1.0 billion sales opportunity.

Novel, long-acting, dual-action bronchodilator combinations will expand the COPD market from 2012, with novel triple combinations on the horizon. Altana/Pfizer's Daxas will achieve peak sales of $750 million by 2010, although 12-month data and combination trials with Spiriva will be key to success.

Reasons to Purchase
  • Understand unmet needs in the respiratory market, and how late-stage compounds address these needs
  • Identify potential licensing opportunities for respiratory market entry or portfolio expansion
  • Benchmark key late-stage asthma and COPD compounds against market leaders
