Genetic Therapy
This program is working to advance a gene delivery vehicle that targets cells in the lung. 4D-710 is a customized adeno-associated virus (AAV) vector designed to deliver a healthy CFTR gene specifically to cells in the lungs of people with CF. This would allow the lung cells to create normally functioning CFTR protein, regardless of an individual’s specific CFTR gene mutation.
Status
A Phase 1 study to test the safety of 4D-710 in adults with CF is underway.
Sponsor
This program is sponsored by 4D Molecular Therapeutics and partially funded by the Cystic Fibrosis Foundation. It is being conducted through the Therapeutics Development Network.
VX-522 is an inhaled messenger RNA (mRNA) therapy. It aims to deliver a full-length copy of CFTR mRNA to lung cells using a lipid nanoparticle. Lung cells would then use the instructions in the mRNA to create functional CFTR protein. This type of therapy could work for any person with CF, regardless of their CFTR mutations.
Status
A phase 1 study to test the safety and tolerability of VX-522 is underway. The study is for adults with CF who have CFTR mutations that are not responsive to CFTR modulator therapy.

This program is working to develop potential therapies for people with CF who have splicing mutations. Splicing is an essential process in which RNA is cut into pieces and then stitched back together in a specific way. Splicing mutations in the CFTR gene cause the RNA to be cut or stitched incorrectly, leading to a mutated CFTR protein. This program is studying short nucleotides, or small pieces of genetic material, that are designed to bind to RNA and change its properties in specific ways. In the case of a splicing mutation, the short nucleotide is designed to ensure that the RNA is cut and stitched correctly, allowing functional CFTR protein to be made.
Status
Laboratory studies to develop and test this potential therapy are underway.

This program is working to develop a non-viral method to deliver a healthy copy of the CFTR gene into the lung cells of people with CF. This would allow cells to create normally functioning CFTR protein, regardless of an individual’s specific CFTR mutation.
This program plans to use extracellular vesicles — bits of cell membrane that naturally bud off from cells to form tiny particles. Once loaded with the gene therapy, these particles can be either inhaled or infused through an IV. This method of delivering healthy CFTR genes shows promise because it harnesses a natural process in the body that is unlikely to trigger an immune system response.

This program is developing a novel approach to deliver a gene therapy to the lung cells of people with CF. Researchers are exploring how to engineer bacteriophage — specialized viruses that typically target bacteria — to deliver the CFTR gene to people with CF. Researchers believe phage-derived particles might be effective because they are unlikely to trigger an immune response, allowing the gene therapy to be re-dosed when needed. Other advantages of this approach include the potential to target specific organs with full-length human genes.
If successful, this gene delivery vehicle would deliver a healthy CFTR gene to lung cells, which would allow the cells to produce functional CFTR protein. This approach has the potential to provide a treatment for all people living with CF, regardless of mutation.

This program is exploring polymer nanoparticles, a type of delivery vehicle that could be used to carry genetic therapies into the lung. Compared to other delivery vehicles, these polymer nanoparticles could more accurately target lung cells and potentially better resist the thick, sticky mucus that clogs the lungs of people with CF.
At first, Nanite will work on developing polymer nanoparticles that can deliver messenger RNA (mRNA) therapy into the lungs. Delivery of mRNA would allow lung cells to make full-length, functional CFTR protein, regardless of an individual’s CFTR mutations. Eventually, Nanite hopes these nanoparticles can be used to deliver other types of genetic therapies, such as gene therapy or gene editing, and target other organs affected by CF, such as the pancreas.

Restore CFTR Protein
Elexacaftor + tezacaftor + ivacaftor (Trikafta™) is a combination therapy combining three CFTR modulators. Elexacaftor and tezacaftor are CFTR correctors, a type of modulator designed to fix the defective CFTR protein so that it can move to the proper place on the cell surface. Ivacaftor is a potentiator. Once CFTR protein reaches the cell surface, potentiators help facilitate the opening of the chloride channel to allow chloride and sodium (salt) to move in and out of the cell.
Status
Trikafta® is approved for people with CF who are 12 years and older who have at least one copy of the F508del mutation or one of 177 other approved mutations. Click here to see a list of all of the mutations currently approved by the FDA for Trikafta® (see page 8 for a list of approved mutations).
Two phase 3 studies to test the safety and effectiveness of Trikafta™ in people with CF 12 years and older have been completed. People with two copies of the F508del mutation had a 10 percent increase in lung function compared to treatment with the modulator tezacaftor/ivacaftor (Symdeko®), and people with one copy of F508del had more than a 14 percent increase in lung function compared to placebo. In people with one copy of the F508del mutation, Trikafta® was also associated with significant improvements in sweat chloride, pulmonary exacerbations and quality of life.
A study of Trikafta® in children with CF ages 2-5 years old is currently underway.

Sponsor
The program was funded by the Cystic Fibrosis Foundation.
Brenscocatib is an oral drug designed to block the function of enzymes, such as neutrophil elastase, that play an essential role in inflammation. When the lungs are infected with bacteria, white blood cells release these enzymes, including neutrophil elastase, to fight the infection. In CF, these enzymes can result in excessive inflammation that causes damage to the lungs. Brensocatib may decrease this damage by inhibiting neutrophil elastase and decreasing inflammation in the lungs.

Inhaled colistin is an antibiotic being studied to potentially treat chronic Pseudomonas aeruginosa infections in people with cystic fibrosis (CF). Although it is approved in Europe, inhaled colistin is not approved for use in the U.S. Currently, the only approved inhaled antibiotics in the U.S. are tobramycin and aztreonam. However, many people with CF find that over time these therapies become less effective at treating their infections. Additionally, because there are few oral antibiotics that treat Pseudomonas, people with CF often must go on IV antibiotics when they have pulmonary exacerbations, a sudden worsening of respiratory symptoms caused by lung infections. IV antibiotics are problematic because they can cause hearing loss and kidney problems. Inhaled colistin could provide an additional option to help people with CF who are not responding to current treatments.
Status
Inhaled colistin is approved in Europe. In the U.S., toxicity studies are planned to confirm potentially safe dosages of the drug, in addition to a Phase 3 study to test the drug’s safety and effectiveness in people with CF.

Opelconazole is an inhaled drug that may prevent Aspergillus fungal infections in lung transplant recipients. There are many challenges associated with current treatment options for people infected with Aspergillus. They may be hard to tolerate, which may lead many patients to discontinue use before they have completed the treatment’s course. Some current treatments may also interact with other common transplant medicines, resulting in potentially serious side effects. This program will study whether inhaled opelconazole will be well tolerated and less likely to have drug-drug interactions. As an inhaled treatment option, it has the potential for being adminstered at home, instead of at a transplant or CF care center.
