The Ethics of Snipping DNA with CRISPR with Rachel Haurwitz (Caribou Biosciences)

TL;DR

CRISPR gene editing is being used to develop off-the-shelf cancer therapies, eliminating the need for patient-specific treatments.

Transcript

all right thanks for coming back with us again thanks for having me I really appreciate it yeah so I just want to talk about two years ago you're with us on TechCrunch Disrupt and it was called out Chris purring animals but you've since moved on to Chris purring humans why is that yeah so I think like many startup companies we've gone through a cou...

Key Insights

• ♋ CRISPR gene editing has the potential to revolutionize cancer therapy by developing off-the-shelf products instead of patient-specific treatments.
• 💅 Car T-cell therapy can be enhanced using gene editing to create more effective cancer-fighting cells.
• 👨‍🔬 The field of gene editing is expanding beyond cancer, with research being conducted on treating genetic disorders like Huntington's disease.
• 😒 Ethical considerations are important in determining the appropriate use of gene editing technology, including establishing guidelines for human embryo editing and germline editing.
• 🪡 DIY gene editing is dangerous and irresponsible, and regulation is needed to prevent misuse of the technology.
• 👨‍🔬 The consequences and long-term effects of gene editing in humans are still being researched, but current focus is on developing safe and efficacious therapies.

Questions & Answers

Q: What led to Caribou Biosciences shifting their focus from animal gene editing to cancer therapies for humans?

Caribou Biosciences recognized the potential of their improved CRISPR technology and decided to invest in developing their own products, specifically cancer therapies using gene editing.

Q: How does CRISPR gene editing work with Car T-cell therapy for cancer treatment?

Car T-cell therapy involves using a patient's own immune cells, which are engineered to recognize and attack cancer cells expressing specific proteins. Gene editing can enhance this process by developing off-the-shelf products from healthy donor cells.

Q: Can CRISPR gene editing be used to treat other diseases like Alzheimer's?

While Caribou Biosciences is currently focused on cancer, the broader gene editing field is exploring therapies for various genetic disorders, including research on Huntington's disease.

Q: Are there other companies working on gene editing therapies?

Yes, another notable company in the gene editing space is CRISPR Therapeutics, which is working on treating beta thalassemia and sickle cell disease using CRISPR.

Summary & Key Takeaways

• Chris Purring, the founder of Caribou Biosciences, explains their transition from working on CRISPR gene editing in animals to developing cancer therapies for humans.

• Car T-cell therapy, which involves engineering a patient's immune cells to target and fight cancer, can be improved using gene editing to create off-the-shelf products.

• The use of gene editing in cancer therapy is highly specific and requires targeting proteins on cancer cells, such as cd19 in certain types of non-Hodgkin's lymphomas.

• While Caribou is currently focused on cancer, the broader gene editing field includes research on treating genetic disorders like Huntington's disease.
