Trial ID	Title	Status	Sponsor	Phase	Start Date	Summary
NCT00787722 ↗	Hematopoietic Stem Cell Transplant in Devic's Disease	Completed	Northwestern University	Phase 1/Phase 2	2009-10-10	This study is designed to examine whether treating Devic's disease patients with high dose cyclophosphamide together with rabbit antithymocyte globulin (rATG)/rituximab (drugs which reduce the function of the immune system), followed by return of previously collected patient's stem cells will result in improvement in Devic's disease. Stem cells are undeveloped cells that have the capacity to grow into mature blood cells, which normally circulate in the blood stream. The purpose of the intense chemotherapy is to destroy the cells in patient's immune system, which may be causing his/her disease. The purpose of the stem cell infusion is to produce a normal immune system that will no longer attack patient's body. The purpose of study is to examine the safety and efficacy of this treatment. The drugs used in this study treatment are drugs for commonly used for immune suppression.
NCT01445821 ↗	Autologous Stem Cell Systemic Sclerosis Immune Suppression Trial	Terminated	Northwestern University	Phase 3	2011-09-15	ASSIST I was the first randomized trial in patients with scleroderma to not just slow disease progression but rather actually reverse it. It is the first treatment to have ever demonstrated reversal of lung disease in scleroderma with improvement in FVC, total lung capacity (TLC), high-resolution computed tomography (HRCT), and QOL. We now, therefore, purpose to compare the ASSIST I conditioning regimen of cyclophosphamide and rATG to a less intense regimen of rATG/cyclophosphamide/Fludarabine. In the new regimen the cyclophosphamide dose is decreased to 120mg/kg (60mg/kg/day x 2) compared to 200mg/kg (50mg/kg/day) in the standard regimen. The lower dose of cyclophosphamide will be less cardiotoxic. This study will determine if the less cardiotoxic regimen will be safer than the standard regimen and as effective as the standard regimen.
NCT02098109 ↗	Non-inferiority Study of XM02 Filgrastim (Granix) and Filgrastim (Neupogen) in Combination With Plerixafor for Autologous Stem Cell Mobilization in Patients With Multiple Myeloma or Non-Hodgkin Lymphoma	Completed	Washington University School of Medicine	Phase 2	2014-08-20	This study will compare the results of stem cell mobilization using drugs called filgrastim (Neupogen) and plerixafor with the results of stem cell mobilization using drugs called XM02 filgrastim (Granix) and plerixafor.

GRANIX Market Analysis and Financial Projection

GRANIX: Clinical Trials, Market Analysis, and Projections

Introduction

GRANIX, also known as tbo-filgrastim, is a non-glycosylated recombinant methionyl human granulocyte colony-stimulating factor (r-metHuG-CSF) approved by the FDA for reducing the duration of severe neutropenia in patients with nonmyeloid malignancies receiving myelosuppressive anticancer drugs. Here, we delve into the clinical trials, market analysis, and projections for this drug.

Clinical Trials Overview

Adult Patients

The efficacy and safety of GRANIX were evaluated in several randomized clinical trials involving adult patients with various types of cancer. These trials included patients with breast cancer, lung cancer, and non-Hodgkin’s lymphoma. Here are some key findings:

• Breast Cancer Study: In a multinational, multicenter, randomized, controlled Phase 3 study, 348 chemotherapy-naive patients with high-risk stage II, III, or IV breast cancer received either GRANIX, a placebo, or a non-US-approved filgrastim product. GRANIX significantly reduced the duration of severe neutropenia compared to the placebo group (1.1 days vs. 3.8 days)[1][3][4].

• Lung Cancer and Non-Hodgkin’s Lymphoma Studies: Similar studies were conducted for lung cancer and non-Hodgkin’s lymphoma, with GRANIX demonstrating efficacy in reducing severe neutropenia in these patient populations as well[1][4].

Pediatric Patients

The safety and effectiveness of GRANIX in pediatric patients were assessed in a single-arm clinical trial involving 50 patients with solid tumors treated for chemotherapy-induced neutropenia. The pharmacokinetics and safety profile of GRANIX in pediatric patients were found to be similar to those in adults[1][4].

Adverse Reactions

Common adverse reactions associated with GRANIX include bone pain, myalgia, headache, vomiting, cutaneous vasculitis, and thrombytopenia. Bone pain was the most frequent treatment-emergent adverse reaction, occurring in approximately 3.4% of patients treated with GRANIX[1][3][4].

Market Analysis

Market Entry and Adoption

GRANIX entered the US market as a quasi-biosimilar to Neupogen (filgrastim), another G-CSF product. The adoption rate of GRANIX and other biosimilars in the filgrastim market has been gradual compared to the rapid shift seen with generic drugs.

• Market Share: GRANIX captured a market share of around 5-10% within six months of its launch, with a price discount of approximately 11-23% compared to the branded product Neupogen. This is in contrast to generic drugs, which typically capture over 75% of the market share within six months with price discounts exceeding 40%[2].

• Provider Differences: The uptake of GRANIX and other biosimilars varies among different provider types. Office-based providers have shown a higher adoption rate compared to providers in outpatient hospitals. After three years, the share of biosimilar filgrastim claims, including GRANIX, was higher among office-based providers (54%) than outpatient hospital-based providers (35%)[5].

Competitive Landscape

The filgrastim market is competitive, with multiple biosimilars available, including Zarxio. Zarxio, another biosimilar to Neupogen, has also seen significant adoption, particularly among office-based providers. The total count of filgrastim claims has been increasing since the mid-2016 introduction of biosimilars, indicating a growing acceptance of these products in clinical practice[5].

Projections

Market Growth

The biosimilar market, including GRANIX, is expected to continue growing as more providers become aware of and comfortable with these products. The gradual increase in market share over the past few years suggests a steady adoption rate.

• European Experience: European markets have seen higher biosimilar adoption rates, with biosimilar filgrastim capturing between 45% and 87% of the market share in different countries. This trend is likely to influence the US market as well, driving further growth for GRANIX and other biosimilars[5].

Cost Savings

Biosimilars like GRANIX offer significant cost savings compared to their branded counterparts. While the price discounts may not be as deep as those seen with generic drugs, they still represent a substantial reduction in healthcare costs. This cost-effectiveness is expected to drive increased adoption and market penetration.

Regulatory Environment

The regulatory environment continues to evolve, with ongoing efforts to facilitate the approval and adoption of biosimilars. As regulatory pathways become more streamlined, it is likely that more biosimilars will enter the market, further increasing competition and driving down costs.

Key Takeaways

• Clinical Efficacy: GRANIX has demonstrated significant efficacy in reducing the duration of severe neutropenia in patients with nonmyeloid malignancies.
• Safety Profile: The safety profile of GRANIX is consistent with other G-CSF products, with bone pain being the most common adverse reaction.
• Market Adoption: The adoption rate of GRANIX and other biosimilars is gradual but increasing, with office-based providers showing higher adoption rates.
• Cost Savings: Biosimilars like GRANIX offer substantial cost savings, which is expected to drive further market growth.
• Regulatory Environment: An evolving regulatory environment is likely to facilitate the approval and adoption of more biosimilars.
