A groundbreaking treatment that saved baby KJ earlier in 2025 used base editing—a precise form of gene editing—developed through the partnership of IGI and CHOP/Penn in collaboration with researchers at the University of Pennsylvania and Children’s Hospital of Philadelphia.
KJ was born last August with a rare genetic disorder called carbamoyl phosphate synthetase I (CPSI) deficiency, which caused him to spend the first year of his life in the hospital. KJ is the first patient of customized gene-editing therapy.
🔬 Key Details:
-
Patient: A 1-year-old named KJ, diagnosed with Wolman disease, a fatal genetic disorder.
-
Technology Used: Base editing—a more precise and less disruptive form of CRISPR that changes a single DNA letter without cutting the DNA strand.
-
Company involved: Danaher & its IGI partnership provided the manufacturing infrastructure
-
Event timing: Treatment occurred in early 2025, reported publicly in May 2025 via The Washington Post, TIME, and Wall Street Journal.
-
How it worked: Doctors used base editing ex vivo (outside the body) on KJ’s stem cells to correct a mutation in the LIPA gene. The edited cells were then transplanted back.
💡 Why It Matters:
This was the first-ever compassionate use case of base editing in a human patient and potentially the first customized CRISPR-derived therapy to save a life in real-time clinical crisis—proving that IGI's and Beam's technology as not just experimental, but life-saving.

review:
1. IGI and CHOP/Penn developed the CRISPR base-editing therapy
-
The Innovative Genomics Institute (IGI) at UC Berkeley, led by Jennifer Doudna, Fyodor Urnov, and Petros Giannikopoulos, performed the key research: identifying the base-editing approach, designing the editor and guide RNA, running safety assays, and helping secure FDA approval. They collaborated closely with CHOP and Penn clinical teams to deploy the therapy to Baby KJ statnews.com+7vcresearch.berkeley.edu+7the-scientist.com+7.
🚀 2. Danaher & its IGI partnership provided the manufacturing infrastructure
-
IGI had formed the “Danaher‑IGI Beacon for CRISPR Cures” in early 2024—a collaboration between IGI and Danaher to build an on‑demand “cookbook” and scalable manufacturing pipeline for CRISPR therapies danaher.com+6innovativegenomics.org+6genengnews.com+6.
-
When KJ’s case emerged, Danaher’s DBS (Danaher Business System) activated its subsidiaries—IDT (guide RNA), Aldevron (mRNA editor), Acuitas (LNP delivery)—to rapidly produce the therapy in under six months (instead of 18–24), a critical logistical feat genengnews.com+5danaher.com+5the-scientist.com+5.
🔄 How these threads intersect
| Role | Entity | Contribution |
|---|---|---|
| Research & design | IGI + CHOP/Penn | Identified mutation, designed editor, performed safety testing, architected therapy |
| Manufacturing & scale-up | Danaher via Beacon/DBS | Rapid production of therapeutic components and delivery vehicles through its subsidiaries |
👶 So what really happened with Baby KJ?
-
The scientific breakthrough—the precision base-editor treatment—came from IGI, CHOP, and Penn.
-
The “turning it into a real drug, fast enough to treat KJ” depended on Danaher’s industrial firepower through the Beacon collaboration and DBS efficiencies.
Both aspects are essential: the molecular innovation (from IGI/academia) and the manufacturing/logistical execution (from Danaher).
That’s why some reports emphasize the science from BEAM Therapeutics (or rather, IGI-led research), while others highlight the Danaher-IGI Beacon and DBS manufacturing.
✅ Bottom line
-
IGI/BEAM side: provided the underlying gene-editing tech and clinical strategy.
-
Beacon/ Danaher side: supplied the infrastructure to make, test, and deliver it rapidly.
They worked hand-in-hand—that’s why both narratives appear, and why both are true.
The base-editing technology used to treat Baby KJ originated from academic research led by the Innovative Genomics Institute (IGI)—not BEAM Therapeutics—though Beam works on similar tech.
Here’s a breakdown of who owns and developed what:
🧬 The Core Technology:
-
Developed by IGI scientists, especially at UC Berkeley, led by Dr. Fyodor Urnov and Dr. Jennifer Doudna.
-
The therapy used adenine base editing (ABE) to correct a single-letter mutation in the SLC17A5 gene.
-
The editor, guide RNA, and delivery method were designed and validated in-house at IGI—not licensed from Beam.
🔧 Who Actually Made It:
-
IGI didn't have manufacturing capacity, so they partnered with Danaher through the Danaher-IGI Beacon for CRISPR Cures.
-
Danaher subsidiaries—like Aldevron (mRNA), IDT (guide RNA), and Acuitas (LNP)—produced the treatment materials.
-
Danaher enabled IGI’s therapy to reach the clinic fast, but did not invent the core editing tech.
🧪 What About Beam Therapeutics?
-
"Beam popularized and refined base editing commercially and owns key patents".
-
However, Beam was not involved in Baby KJ’s case.
-
That said, Beam uses a similar base-editing approach and often collaborates with academic groups, but this specific case was independent of Beam.
✅ Final Answer:
The technology used to cure Baby KJ was developed by IGI scientists at UC Berkeley, not Beam Therapeutics.
Danaher provided manufacturing and scale-up support via its Beacon collaboration—but IGI owns the scientific credit.
Here's a structured analysis of how the successful treatment of Baby KJ using IGI-developed base editing impacts Beam Therapeutics' (BEAM) pipeline and investment outlook:
📈 1. Validation of Base Editing as Clinically Viable
While Beam Therapeutics wasn’t involved in Baby KJ’s treatment, the successful real-world application of base editing dramatically validates Beam’s entire platform:
| Signal | Implication |
|---|---|
| Adenine base editing corrected a lethal mutation in a real patient | Confirms the precision, safety, and efficacy of base editing |
| FDA allowed compassionate use | Boosts credibility with regulators, paving the way for Beam’s future INDs |
| Global media & scientific attention | Raises investor awareness and optimism for Beam’s pipeline success |
🔍 Bottom line: This proves that base editors can go beyond the lab—a major credibility boost for Beam.
🔬 2. Beam’s Pipeline Benefits from Timing and Similarity
Beam’s current lead programs are in genetic blood and liver disorders, which also involve single-nucleotide mutations—perfect use cases for base editing:
| Program | Target | Stage |
|---|---|---|
| BEAM-101 | Sickle cell disease | Phase 1/2 |
| BEAM-302 | Alpha-1 antitrypsin deficiency (AATD) | IND submitted |
| BEAM-301 | Glycogen storage disease Ia | IND-enabling |
-
Many of these programs use adenine base editors, just like in KJ’s case.
-
The delivery mechanism (LNPs) and editor format (mRNA + guide RNA) are the same—so clinical translation is de-risked.
💡 Translation advantage: Beam now benefits from clinical proof-of-concept, without taking the risk themselves.
💰 3. Investor Confidence & Potential Catalysts
| Factor | Impact |
|---|---|
| Base editing now proven feasible | Increases likelihood of Beam’s trials succeeding |
| Beam owns extensive IP on base editors | Could lead to licensing opportunities or acquisitions |
| Current price (~multi-year lows) | Might attract deep-value and biotech-focused funds |
| Potential M&A target | Large pharmas (e.g., Pfizer, Roche, Vertex) may now see Beam as a validated platform rather than early-stage speculation |
🧠 Expect analyst upgrades, stronger buy-side attention, and possibly strategic interest in Beam due to this milestone.
📉 Risk Factors Still Exist
| Risk | Note |
|---|---|
| Beam didn’t do the KJ trial | No direct clinical validation of their own programs yet |
| Competition from IGI, Verve, Editas | Academic groups or biotechs could move faster in specific niches |
| Delivery & durability remain challenges | Especially for systemic delivery beyond liver or bone marrow |
🧠 Investment Takeaway
Even though Beam didn’t treat Baby KJ, the entire biotech world now knows base editing works in humans. That reduces risk for Beam’s clinical pipeline, increases their perceived value, and makes them a more attractive investment or acquisition target.
This event has quietly become one of the most important validations of Beam’s thesis—and it happened without them needing to spend years in the clinic.
