2021 Gene Therapy Pipeline

author: Kevin Curran PhD

updated: 8/16/2021

Rising Tide Biology presents an updated table of gene therapies on the market and in late stage clinical trials.

China was the first country in the world to approve a commercial gene therapy product. China’s regulatory body, CDFA, approved Gendicine in 2003. Gendicine delivers a p53 gene into tumor cells. As of 2020, over 30,000 patients have received Gendicine treatment for various cancers.

In 2017, the FDA approved Luxturna for U.S. patients. Luxturna is an AAV based gene therapy that treats a rare, genetic form of blindness. In 2019, Zolgensma was FDA approved to treat Spinal Muscular Atrophy. If you suffer from Spinal Muscular Atrophy, you are born without the full sequence gene for SMN in your motor neurons. Zolgensma delivers the SMN gene into motor neuron cells. As of 2021, Zolgensma is commercially available in 38 countries and over a thousand patients have received this life-saving genetic medicine.

The floodgates are now open and hundreds of biotech companies are developing gene therapies. The specific details of each gene therapy are different, however the central challenge is to replace a missing or non-functional protein with a functional protein. Gene therapy achieves this goal by inserting a viable gene into the genome of the cell type that requires the missing protein.

Our table below provides an overview of many of the gene therapies in significant stages of development in 2021. Please keep in mind, our projected U.S. launch dates are merely an estimate. Delays are very common as companies seek regulatory approval.

This table lists gene therapies in significant stages of the clinical pipeline. Many are in Phase 2 or 3, or else have demonstrated efficacy in Ph1/2 trials.

This pipeline changes quickly. I update every 3 months. Am I missing a significant development? Please let me know, you can contact me here.

Analyst reports and the CVS Health Clinical Affairs pipeline document was used as a reference in the table above.

If you’re interested in gene editing (CRISPR, ZFN, TALENS), I’ve also created this separate table of gene editing human clinical trials.

2021 update: I’ve been receiving a lot of email from people asking if a gene therapy trial is occurring for one particular disease. To help these folks, I’ve created a restricted search page on clinicaltrials.gov that only lists gene therapies. First click onto this restricted clinical trial search and then explore trials By Topic. Look for a disease in the topic list or else write in the disease on the adjacent search bar. This will provide a list of gene therapy clinical trials for one particular disease. If you see something of interest, click on a trial and you will find relevant contact information for that trial.

2021 update:

Decentralization in genetic medicine.

I am currently exploring the concept of decentralization in cell and genetic medicine. The shift to a decentralized economy and lifestyle was already underway by 2020, and then the Covid-19 pandemic accelerated this trend. We see this trend in finance, crypto, zoom calls, movement away from urban areas.

How can decentralization benefit the healthcare industry?

gene therapy pipeline

Medicine is becoming more personalized. Cell therapies, such as CAR-T, are perhaps the most dramatic example of personalized medicine. Blood is drawn from a lymphoma patient, their immune cells are separated out and shipped off to a central manufacturer site. A pharmaceutical company genetically modifies each batch of immune cells. These genetically engineered immune cells are then shipped back to the patient and infused back into their body. Thousands of patients have now been treated with these CAR-T cell therapies.

Could this CAR-T process be more efficient if we decentralized the manufacturing process?

What if regional hospitals and academic centers genetically engineered the patients’ immune cells on site, without shipping to a central manufacturer? This could shave many weeks off the processing time. For 3rd line cancer patients, time is critical. Many 3rd line lymphoma patients pass away while waiting for their cells to return from a centralized manufacturer. Each week eliminated in cell manufacturing time would save lives.

This 2020 article in Cancer Therapy and Prevention analyzes the potential costs savings of decentralized cell therapy.

I’ll be exploring various applications of decentralization in cell and genetic medicine in future articles. If this concept is interesting to you, then please reach out and share your thoughts.
