Companion blog · Kylo-11 / Lp(a)
A Lancet Phase 1 gene-silencing shot lowered lipoprotein(a) for nearly a year. Here is what that means — and what it does not prove yet.
Sep 5, 2026 · Doctor Zuleta / ThriveMed · ~8 min read
There is a cholesterol-related number that can sit quietly in your blood for decades. You usually cannot feel it. Diet and exercise barely move it. And most people who have a high level have never been told the number exists.
That number is lipoprotein(a) — written Lp(a), pronounced “L-P-little-a.” On August 28, 2026, a first-in-human Phase 1 trial of an investigational drug called Kylo-11 was published in The Lancet and presented as a late-breaker at ESC in Munich. One subcutaneous injection reduced Lp(a) by roughly half to nearly all — and at the highest doses, that drop held for about 48 weeks.
This is exciting Phase 1 science. It is not proof that Kylo-11 prevents heart attacks. Let me walk you through it the way I would with a patient in clinic.
Think of Lp(a) as LDL’s genetically stickier cousin. Like LDL (“bad cholesterol”), it is a particle that carries cholesterol in the blood. Because of its structure, elevated Lp(a) can contribute to plaque buildup in artery walls and tip clotting tendency — which is why cardiologists care about it as a heart-disease and stroke risk marker.
The key difference: about 80–90% of your Lp(a) level is inherited. Unlike LDL, lifestyle changes do not meaningfully lower Lp(a). Statins and diet can be powerful for other risk factors — and they still matter for overall heart health — but they are not a reliable dial for this one.
There is still no approved drug specifically designed to lower Lp(a). And Lp(a) remains under-tested. Many people with high levels simply do not know it.
Kylo-11 is a long-acting small interfering RNA (siRNA). In simple terms, it is like a mute button for the liver’s Lp(a) factory. The drug delivers a gene-silencing signal to liver cells, reducing production of apo(a) — a building block of Lp(a). With less apo(a) made, the body assembles far fewer Lp(a) particles.
Design, in one breath:
Results across dosing groups: a single injection reduced Lp(a) by approximately 53–97% at 48 weeks. Participants on the highest doses saw reductions of about 95–97%, with the effect sustained for nearly a year. Public coverage notes durable effect at doses ≥225 mg, with the 600 mg group showing a median reduction around 97%.

On safety: the drug was generally well tolerated in this Phase 1 experience. Coverage and the published findings summary report no serious drug-related adverse events in the trial as described.
Phase 1 answers safety and biomarker questions in a relatively small first-in-human study. It does not prove that Kylo-11 prevents heart attacks, strokes, or death. Kylo-11 is not approved and not available for routine clinical use. Cardiovascular outcome trials — and larger Phase 2/3 programs — are what tell us whether deep Lp(a) lowering changes events. A Phase 2 trial is already underway (sponsor: Kylonova Biopharma / Hygieia Pharma / SBP Group, collaborating with Cleveland Clinic investigators).
Excitement is fair. Overclaiming is not. A nearly year-long mute on an “untreatable” genetic risk marker is a meaningful signal. Converting that signal into fewer heart attacks is the next chapter — not this one.
You do not need to wait for an investigational drug to act on the part you control today: knowing your number.
You can’t feel high Lp(a). You can’t diet it away. One blood test — often once in a lifetime — tells you where you stand. Ask for it. Bring the result to your clinician. Follow the science as Phase 2 unfolds — but do not wait for a drug to get tested.

Takeaway
You can’t “feel” high Lp(a). You can’t diet it away. One blood test — often once in a lifetime — tells you where you stand.
Ask your clinician for a lipoprotein(a) / Lp(a) blood test — a once-in-a-lifetime lab for most people. Know your number. Bring it to your next visit.Soft secondary: follow the pipeline (Phase 2 underway) — but don’t wait for a drug to get tested.
How each piece was made — HeyGen video briefs and social prompts, embedded for offline review.
Create a 5 minute video, make sure is at least 5 minutes. inspirational, epic video with cinematic music, Modern with an intro that’s a Hook about what the video is going to be talking about with B roll. In the first 2 seconds start by describing what the video is going to be about with a hook. B roll must be Nat Geo, imax level quality’s That is a visual representation of the subject, at a glance, zooming in into a molecular level. Make sure th animations are scientifically correct animations or B roll of the subject. FRAMING (CRITICAL): This is about a NEW WAY OF DOING HEALTHCARE — proactive, genetics-aware, clinician-led prevention and risk detection. NEVER use the word "longevity". Never say longevity, longevity medicine, or anti-aging. Use language like: proactive care, knowing your risks early, expanding human vitality through better clinical practice, a new standard of care. SUBJECT: Kylo-11 (spell exactly Kylo-11, never KYLLO), Lancet 2026 Phase 1 first-in-human long-duration siRNA lowering lipoprotein(a)/Lp(a). Ashish Sarraju, Cleveland Clinic. One SC injection cut Lp(a) ~53–97% at 48 weeks; highest doses ~95–97% for nearly a year. Lp(a) ~80–90% genetic; diet/exercise barely move it; under-tested. Phase 1 safety + biomarker only — NOT proven CV outcome benefit. Phase 2 underway. CTA: ask once for an Lp(a) blood test. Then introduce Myself as , Hi! if we have not met yet, I am the AI for Dr. zuleta. While he is working clinically and with teams to improve health, i am here sharing his messages. Mention Dr zuleta is the founder of Thrivemed, a company that works to expand human vitality. He writes every script and him and his team read every comment. Then the subject — inspiring potential AND weaknesses — analogies + animations, the study, inspirational outro. Analogies: Lp(a) as genetically sticky cholesterol-like particle; Kylo-11 siRNA as mute button for the liver’s Lp(a) factory (apo(a)). Speech ~1.2x engaging. Lots of B-roll, camera/zoom changes on digital avatar. Don’t say his name more than once. Particle-design twin zoom whole→molecular. When sharing research zoom into TITLE only with highlight animations and show images of the paper. Explain so anyone understands. End with "stay vital" EXACTLY ONCE at the very end — never earlier. Cinematic effects throughout. B-roll like high-end scientific documentary. Music: Epic cinematic hybrid orchestral 105-115 BPM — massive drum + brass braam open, driving staccato strings + sub-bass, deep brass swells, soaring strings, propulsive bed, crescendo to triumphant climax. Polished and grand. Vary musical sections so it does not feel looped or repetitive. No invented clinical claims. No longevity wording.
Create a ~3 minute YouTube video (target 2:45–3:15). Hook in first 2 seconds with Nat Geo/IMAX B-roll of Lp(a) zooming molecular. Intro once: Hi! if we have not met yet, I am the AI for Dr. zuleta. While he is working clinically and with teams to improve health, i am here sharing his messages. ThriveMed expands human vitality. He writes every script; he and his team read every comment. Name at most once. FRAMING: NEW WAY OF DOING HEALTHCARE / proactive clinical risk care. NEVER say longevity. SUBJECT: Kylo-11 (never KYLLO) — Lancet Aug 2026 Phase 1 siRNA for Lp(a). One shot ~53–97% drop at 48 weeks; high doses ~95–97% ~1 year. Sarraju/Cleveland Clinic. Genetic risk; ask for the lab once. Potential + weaknesses: exciting durable lowering; Phase 1 only — not outcome data; Phase 2 underway. Speech ~1.2x. Lots of B-roll, avatar zooms, particle twin. Paper TITLE zoom only + paper imagery. Analogies + correct molecular animations. MUSIC (CRITICAL): Epic cinematic hybrid orchestral 105-115 BPM BUT with clear evolving sections — distinct intro hit, mid verse bed, bridge swell, final climax. DO NOT use a short looping/repetitive bed. Music must feel varied and film-scored, not a repeating loop. OUTRO: Say "stay vital" EXACTLY ONE TIME at the very end. Do not say stay vital earlier. Do not repeat it. No invented claims. No longevity.
Create a short vertical Reel for Instagram Reels / TikTok / YouTube Shorts — portrait 9:16, about 45–60 seconds. MAXIMUM cinematic production value: IMAX scientific documentary look, volumetric light, elegant camera moves, molecular zooms that feel premium film — not stock or flat. Hook in first 2 seconds: most people never get tested for Lp(a); Lancet 2026 one-shot Kylo-11 dropped levels ~95–97% for nearly a year in Phase 1. Navy scrubs digital twin avatar. Speech ~1.2x. Spell Kylo-11 never KYLLO. NEVER say longevity — frame as proactive healthcare / knowing your inherited risk. Brief AI-for-Dr-Zuleta only if it fits without killing pace. ThriveMed once max.
