In people, 2 mg into a vein three times a week for four weeks moved the small-fibre symptom score by −11.5 against −2.9 on placebo in 22 people with sarcoidosis, p < 0.05, and a second randomised trial counted fibres regrowing. It is eleven amino acids copied off one face of erythropoietin, the hormone the kidneys use to order red blood cells, cut to reach that hormone's repair job and physically unable to reach its blood job — so it does not raise red cell count and does not carry erythropoietin's clotting risk. Six randomised, placebo-controlled trials have given it to people: three hit what they set out to change and three missed, and the misses include the fibre count in a skin sample in both sarcoidosis trials that measured it. That is the strongest human evidence behind any compound on this site, and it is still one disease, three hits, and a structural measure that did not separate.\n\n**What the evidence supports doing.** Take it for burning, numb or electrically painful feet arising from sarcoidosis, at the doses the trials used — 4 mg a day under the skin for 28 days, or 2 mg into a vein three times weekly — and expect the symptom score to move while the fibre count may not. Do not expect anything from it in a compressed nerve root or in sciatica: no trial has ever enrolled a person with a back problem. And a person with no damage should expect nothing at all, because the receptor it binds does not assemble on healthy cells — eleven diabetic subjects in the 2015 trial started with normal corneal nerve counts and their numbers did not move.\n\n**Against what a doctor prescribes for the same pain.** The drugs given first for nerve pain have their own numbers, from Finnerup and colleagues' meta-analysis of 229 randomised double-blind trials in Lancet Neurology in 2015, counting how many people must be treated for one to get half their pain taken away: 6.4 for the serotonin-noradrenaline drugs, mostly duloxetine; 7.2 for gabapentin; 7.7 for pregabalin. Those are weak numbers — six to eight people treated per person helped — and every one of them works by damping the signal rather than by rebuilding the fibre. ARA-290 is the only thing here proposed to rebuild the fibre, and it has been measured in 132 people who received it, in one disease, over 12 weeks at most. Neither side has anything measured past twelve weeks.\n\n> **The number most people need first: the trials gave 4 mg a day. Public reports of self-use run 250 to 1,000 mcg a day — four to sixteen times less, and below the lowest arm of the only dose-ranging trial ever run, which itself missed at 1 mg. Whatever the trials showed, almost nobody is taking that dose.** Nothing else written up on this site has that record. This is the one compound here whose evidence starts in people rather than in rats.\n\nOne disclosure, because it should change how you read the rest. The operator of this site has a commercial interest in compounds described here. That is a reason to weigh what is on this page against the sources it cites rather than against its tone, and every claim below carries the source that supports it for exactly that reason.\nThe compound is ARA-290, also written cibinetide. It is eleven amino acids in a row, copied off one face of a hormone your kidneys already make — erythropoietin, the hormone that tells bone marrow to build red blood cells. That hormone does a second job as well: it keeps injured cells from dying and helps damaged nerves grow back. The two jobs run through two different docking points on the cell. ARA-290 was cut out of the parent molecule to hit the repair one and miss the blood one. It does not raise your red cell count and it does not carry erythropoietin's clotting risk.\n\nIf you have burning feet, numb toes, electric jabs in the legs at night, o","ranking":"safety-first (interaction_risk/limitations), then quote-gated effective_weight","claims":[{"id":"c30","text":"Cibinetide received EMA orphan designation EU/3/13/1191 for sarcoidosis (7 October 2013), FDA Fast Track (28 October 2014), FDA Orphan Drug designation (5 July 2016) and EMA orphan designation EU/3/16/1721 for pancreatic islet graft loss (29 August 2016);
