CF Foundation ‘Venture Philanthropy’ Model Crucial to CF Breakthroughs

By Larry Luxner

When the Cystic Fibrosis Foundation (CFF) was established in 1955, most people with cystic fibrosis (CF) didn’t make it to their sixth birthday. Today, the average life expectancy of a CF patient is 47 years.

To date, the U.S. Food and Drug Administration has approved 12 CF therapies. Three of them are CFTR modulators that treat the basic disease-causing defect, benefiting 60 percent of all patients, and more therapies are on the way.

Preston W. Campbell III, the CFF’s president and CEO, directly attributes this dramatic improvement to the foundation’s philosophy of “venture philanthropy.”

“We are now in Phase 3 CFTR trials that, if successful, will mean that as early as next year, more than 90 percent of all individuals with CF will have a highly effective therapy targeting CF’s basic defect,” he said. “More therapies that treat the complications of CF are in the pipeline than ever before.

“It begs the question: how did all of this happen?”

Campbell answered that during his March 26 presentation, “Patient advocates taking a real stand in drug development: How the CFF worked with biotech and pharma to find a cure,” at the 2018 World Orphan Drug Congress USA in Oxon Hill, Maryland.

Back in 1960, the Bethesda, Maryland-based foundation broke ground by establishing a Care Center Network to provide multidisciplinary care. Within five more years, it had formed a patient registry.

With only $400,000 in the bank, it would also commit $11 million to research, Campbell said. “Five years later, in 1985, the basic CF defect was identified, and in 1989, the CFTR gene was discovered. That opened the floodgates,” he added.

Campbell’s predecessor, Robert J. Beall, created the Therapeutics Development Program — now called its Venture Philanthropy Model — in 1998 to entice industry to focus on CF, and specifically on CFTR as a target. Its three components were financial assistance, research tools and scientific advice, and a clinical trials network.

“We would lower the risk for industry to come into the CF space. We also made our research tools and scientific advice freely available, and we also embedded the best scientists in the world in these industry programs,” said Campbell, who took over from Beall as head of the CFF in January 2016. “Finally, in order to make sure clinical trials were safely and efficiently done, we created a clinical trials network that originally had seven centers and now has 89.”

In the beginning, CFF’s investments were typically in the $1.5 million range. Ultimately, the foundation invested more than $100 million in Aurora and its successor, Vertex Pharmaceuticals, whose headquarters are in Boston.

To date, the FDA has approved three Vertex CFTR modulators: Kalydeco (ivacaftor) for patients with the G551D mutation in the CFTR gene (2012); Orkambi (lumacaftor/ivacaftor)for patients who are homozygous for F508del, the most common mutation in the CFTR gene (2015); and Symdeko (tezacaftor/ivacaftor) for homozygous F508del patients as well as others (2018).

“Payments are milestone-based, so we pay for success,” Campbell said. “A scientific advisory committee determines if milestones are met and if the project should continue. Successful programs offer a return on our investment, so if the program is foundering, we shake hands and walk away.”

‘Sham’ or public interest? ICER suggests 70%-plus discounts on Vertex’s cystic fibrosis drugs

By Angus Liu

Vertex has often talked about its admiration for Gilead, setting the big biotech’s ability to roll out multiple antivirals as a model for its cystic fibrosis endeavor. Now, though, it faces the same pricing issue once pinned on Gilead’s hepatitis C franchise. But the company refuses to play sitting duck.

In a new report, the U.S. cost-effectiveness watchdog the Institute for Clinical and Economic Review argues that Vertex’s cystic fibrosis trio—Kalydeco, Orkambi and newly approved Symdeko—need a huge price cut to achieve cost-effectiveness. Its suggested discount? Over 70%. Continue reading ‘Sham’ or public interest? ICER suggests 70%-plus discounts on Vertex’s cystic fibrosis drugs

Introduction of New Therapies Affects Pregnancy Rates in Women With CF

The overall rate at which women with cystic fibrosis are becoming pregnant dropped slightly in recent years — coinciding with the introduction of CFTR modulators and the clinical trials that led to their approval as CF therapies — but appears to be rising again to pre-trial levels, a study reports.  Continue reading Introduction of New Therapies Affects Pregnancy Rates in Women With CF

New Promising Results from Phase 3 of Combination Therapy

Findings from a phase 3 trial evaluating the efficacy and safety of tezacaftor in combination with ivacaftor in patients with cystic fibrosis (CF) who were homozygous for the Phe508del mutation were published in the New England Journal of Medicine.

The Phe508del mutation has been known to result in greatly reduced conductance regulator (CFTR) protein activity and a loss of chloride secretion, which can lead to impaction of mucus in the airways, gastrointestinal tract, and exocrine organs, with the potential for severe clinical consequences including gradual loss of lung function, nutritional deficits, pulmonary exacerbations, and respiratory failure. It is the most prevalent CFTR mutation worldwide, and affects approximately 46% of American CF patients.

Previous data has shown Ivacaftor’s association with a rate of progressive decline in lung function that is lower than that in untreated patients. In a phase 2 clinical trial involving patients who were homozygous for the Phe508del mutation or heterozygous for the Phe508del and G551D mutations, when combined with the investigational CFTR corrector tezacaftor, it has exhibited enhanced CFTR function and improved lung function.

In August, just one month removed from Vertex’s announcement of positive datafrom Phase 1 and Phase 2 studies, Rare Disease Report covered the acceptance of applications for the use of the tezacaftor/ivacaftor combination treatment in this patient population by the U.S. Food and Drug Administration (FDA) and European Medicines Agency (EMA).

The phase 3 trial enrolled a total of 510 patients 12 years and older with CF who were homozygous for the Phe508del CFTR mutation at 91 sites in the U.S., Canada, and Europe from January 30, 2015 to January 20, 2017. Patients were randomly assigned to be administered either tezacaftor and ivacaftor (administered as a fixed-dose combination tablet containing 100 mg of tezacaftor and 150 mg of ivacaftor in the morning and a tablet containing 150 mg of ivacaftor in the evening) combination therapy or placebo for 24 weeks.

In total, 475 patients completed the full 24 weeks of the trial, with 93.6% (n=235) in the tezacaftor-ivacaftor group and 93% (n=240) in the placebo group. While no significant difference in the body mass index (BMI) was experienced between the groups at week 24, the use of the combination therapy led to a significantly greater absolute change from baseline in the predicted forced expiratory volume in 1 second (FEV1) than placebo. Despite advances in standard-of-care therapy, patients with CF continue to lose lung function at a rate of an estimated 1% to 3% per year. This trial exhibited a significant effect of the combination therapy compared to the placebo, as the mean absolute change from baseline in FEV1 through week 24 was 3.4 percentage points in the former, compared to 0.6 in the latter.

The most common adverse events (AEs) among the enrolled patients included infective pulmonary exacerbation, cough, headache, nasopharyngitis, increased sputum production, pyrecia, hemoptysis, oropharyngeal pain, and fatigue. The incidence of AEs was similar in both the group for combination therapy and the placebo group, however, those treated with lumacaftor-ivacaftor in the phase 3 did not experience an increased incidence of respiratory events (33 patients [13.1%] vs. 41 patients [15.9%]).

This improved safety profile of the tezacaftor-ivacaftor combination supports its use in a broad range of patients with CF, and, if approved, the therapy will be the third of Vertex’s drugs approved for CF patients, and the second intended specifically to treat patients with F508del mutations (Orkami [lumacaftor/ivacaftor]).

Tezacaftor/Ivacaftor Gets Priority Review for Cystic Fibrosis

The Food and Drug Administration (FDA) has granted Priority Review to the New Drug Application (NDA) of tezacaftor/ivacaftor (Vertex) for the treatment of patients ≥12yrs old with cystic fibrosis (CF) who have two copies of the F508del mutation or one F508del mutation and one residual function mutation.

The NDA submission was based on positive results from 2 global Phase 3 trials, which showed statistically significant improvements in lung function (percent predicted forced expiratory volume in one second, or ppFEV1) in patients treated with tezacaftor/ivacaftor.

The combination treatment consists of ivacaftor (marketed under the brand name Kalydeco), a cystic fibrosis transmembrane conductance regulator (CFTR) potentiator, and tezacaftor, a novel CFTR corrector. Tezacaftor is designed to address the processing defect of F508del-CFTR to enable it to reach the cell surface, where ivacaftor can further enhance the protein’s function.

The FDA has set a Prescription Drug User Fee Act (PDUFA) target date of February 28, 2018 to make a decision on the NDA.
