The GIST

 

This is the first of a series of blogs on ongoing projects in ME/CFS, long COVID, etc.

Lifeline

With another lifeline unlikely, RECOVER had better come through with what it has.

We’re back focused on the “Treating Long COVID” portion of the NIH’s RECOVER project for long COVID. Why cover RECOVER? Because with about $1.8 billion to its name, it’s easily got the biggest budget in long-COVID land. It spent about $170 million on its first round of clinical trials and then got a $500 million boost from the Biden administration.

With the Trump administration not exactly engaged in medical research funding, we can’t expect any more lifelines. RECOVER had better deliver on what it has.

It’s been a year since the last RECOVER TLC (Treating Long COVID) Workshop occurred and a lot has changed. Two major long-COVID and ME/CFS supporters (NIH Director Bertagnolli/NIAID Director Marrazzo) are gone, replaced by NIH Director Jay Bhattacharya and acting NIAID Director Jeffrey Taubenberger. Neither has a record with long COVID or ME/CFS.

It was good to simply see NIH Director Jay Bhattacharya show up at the beginning of the two-day RECOVER TLC symposium in September.

He knew that given all the upheavals of the last 9 months, the billions of dollars of NIH funding paused or cut, the closure of the Long COVID office, and the order (quickly rescinded) to terminate all RECOVER long-COVID grants, he was probably speaking to a rather skeptical audience.

We’ll see how RECOVER and long COVID does at the new NIH, but at least at this point, Bhattacharya knocked it out of the park, stating that the NIH was committed to understanding and finding treatments for long COVID and related diseases including ME/CFS and Lyme disease.

    As the word spread more and more doctors on the listserve began using GLP-1 agonists

    The RECOVER Initiative’s first round of long COVID clinical trials landed with a thud.  Now, a year after the first “Treating Long COVID” Workshop, they’re back with another round.

  • Progress has clearly been made. RECOVER’s next round of long COVID clinical trials are more proactive and creative. They include four treatments.
  • The Low Dose Naltrexone (LDN) trial begged the question of whether long COVID needs an LDN trial when the drug is so well known and when other  LDN trials are underway. On the other hand, the RECOVER LDN trial is designed to be “pivotal”; i.e., it will be large enough that RECOVER hopes it will start the process toward FDA approval of the compounded drug.
  • “RECOVER’s” Baricitiinib trial turned out to be an add-on to Wes Ely’s already active $12 million trial funded in 2024. By incorporating the trial into its clinical network, RECOVER will help the trial be completed faster.  With many resources being poured into this trial, many people are convinced that Baricitinib, which was first approved for COVID-19, has a good chance of success. Let’s hope they’re right. Even with the help, though, we probably won’t get any results until sometime in 2027.
  • GLP-1 Agonists – RECOVER knocked it out of the park by choosing to listen to doctors and patients and supporting a drug that has not been studied in long COVID. Dr. Kaufman noted that a survey of doctors in a large complex, chronic illness listserv found that 60% of 350 responses saw their patients improve their fatigue, pain, and other symptoms using very low doses of these drugs.  Kaufman reported that in his experience, improvements in fatigue were unusual.  The protocols for the trial are being produced now. This mechanistic trial aims to elucidate the physiological effects of the treatment.
  • Stellate Ganglia Blockade (SGB) – Stellate ganglia blockade was another inspired choice. Both small studies and anecdotal reports suggest that this unusual treatment, which involves injecting an anesthetic into the neurons making up the stellate ganglion in the neck, may be quite helpful in some people.  The block temporarily reduces sympathetic nervous activity in the upper chest, neck, and head, potentially allowing the system to reset itself.  A powerful video showed how dramatic the effects can be in some people. The SGB trial is another mechanistic trial that will dig deep into what physiological effects the blockade is having.
  • Money Issues? – RECOVER had stated that it expected to fund two “pivotal” trials and four mechanistic trials, but as of September, it ended up funding one pivotal trial, two mechanistic trials, and helped out on a large trial that was already underway.
  • Given the great need for treatment trials, the few trials underway suggest RECOVER may have run through most of its $1.8 billion in funding. The Biden administration extended a $500 million lifeline to RECOVER in 2024, but that’s not likely to happen, again, given the Trump administration’s apparent antipathy to NIH funding.
  • This may be it, then, for RECOVER’s clinical trials and underscores how unfortunate it was that RECOVER poured over $120 million into its first batch of underwhelming trials. Finding that Ivabradine, IVIG, modafinil, Sunosi, tDSC, and other therapies are helpful will help primary care doctors provide better treatments for their long COVID patients, but it will have come at a high cost. The results of most of those trials will be available by the end of 2026.

RECOVER’s New Clinical Trials

With long-COVID patients grasping for effective treatments, the RECOVER Initiative’s eagerly anticipated first round of clinical trials landed with a thud. Not even the patients were happy. RECOVER spent approximately $170 million on 13 treatments, but the conservative nature of the trials and the lack of interest in using the trials to understand long-COVID pathophysiology drew criticism.

Let’s be clear, though, that if RECOVER determines that Ivabradine, IVIG, modafinil, Sunosi, tDSC and other therapies are helpful, that will help primary care doctors provide better treatments for their long-COVID patients.

Still, when it came time for the RECOVER TLC symposium last year, it was clear things had to change, and the symposium suggested that they were about to change radically.

RECOVER TLC-2

Did things change radically? No, but they did change, and the next swath of clinical trials – just four of them, is a clear step up.

Things are still moving slowly – none of the new trials have started. Indeed, about a year later, it appears that by September, most of them had just been chosen. Then, again, RECOVER did not make its task easy, when it asked the public for suggestions. The public responded – with 572 possible treatments – all of which needed to be assessed.

RECOVER focused on agents that already had some clinical support. People from academia, patients with lived experience, industry, and government collectively scored the 136 submissions that made it through the first filter.

mechanisms

The treatment side of RECOVER bemoaned how little we know about the mechanisms causing long COVID. The research side of RECOVER has largely ignored that aspect of long COVID.

It was ironic to hear RECOVER presenters bemoaning the fact that they couldn’t take the normal approach to treatments because we don’t know the molecular pathways, given that RECOVER has spent the vast majority of its almost $2 billion on observational studies, which will never shed any light on them. Even its treatment trials were structured to ensure they didn’t shed any light on the molecular pathways or mechanisms underlying long COVID.

Five years into the illness, with no clear mechanisms in place, RECOVER turned to the community, including clinicians and patients, for ideas. Some people, understandably arguing that we pretty much know that no really effective treatment exists, wanted RECOVER to swing out and focus on novel drugs. Others argued that we need to document whatever is working (however poorly) in long COVID.

The Four Drugs

A disappointing small slate of drugs was chosen for the next series of trials. These four drugs/treatments, though, get a rare chance in this space – a chance at a large, well-organized, rigorous clinical trial.

While one can quibble about the choices, RECOVER mostly rose to the occasion by choosing a well-known drug (LDN) which needs more documentation, an immunomodulatory drug (Baricitinib) (which was already being studied), an exciting new entrant (GLP-1 agonists) into the long-COVID/ME/CFS space, and the big surprise of the bunch – a treatment approach (stellate ganglion blockade) with real promise but which desperately needs more rigorous testing.

Particularly with the last two, kudos to RECOVER for keeping up with the long-COVID clinical space and choosing two treatments without a lot of hard clinical evidence, but which appear to be quite promising.

Needed or Not Needed? The Low Dose Naltrexone (LDN) Trial

LDN barely missed the cutoff in the first trials. I didn’t watch the presentation because LDN is such a well-known drug. The big question facing this trial is how much do we really need a long-COVID LDN trial? What treatment do we know less about that LDN knocked out?

choices

Good or bad choice – you decide.

The same question should have been asked about Paxlovid. With multiple Paxlovid trials underway, was it really necessary for RECOVER to put on its own, almost 1,000-person, very expensive trial? (The answer, after the fact, was clearly no.)

A small, long-COVID LDN trial has been completed, and at least three more LC trials involving approximately 250 patients are currently underway. RECOVER’s LDN trial will surely be large and rigorously done, and will undoubtedly help the field, and if successful, promote LDN to many primary care doctors. Those are all good things.

This will likely be a large “pivotal” trial that will tell us the goods, one way or another, on LDN’s effectiveness in long COVID. It’s a conservative, if understandable, choice from RECOVER. In a bit of good news, an NIAID spokesperson said, “RECOVER-TLC will seek to develop a ‘regulatory-grade LDN study product’ that may be a candidate for approval alongside the trial.” If RECOVER can move LDN to FDA approval, this trial will have been worth it.

The Add-On – The Baricitinib Trial

“We’re going to get across the finish line faster,”  Wes Ely

Adding sites

RECOVER will add clinical sites and embed the Baricitinib trial in its database, thereby quickening and strengthening the study.

Baricitinib is another interesting choice. It’s a great candidate, it was approved for use in COVID-19, has a good safety profile, could tamp down neuroinflammation … that’s all good stuff, but Ely’s REVERSE-LC $12 million trial was funded by the National Institute of Aging in 2024. With this “RECOVER trial”, RECOVER has simply joined the fun.

RECOVER is enabling the trial to use its clinical sites and expand more rapidly. It’s also embedding the trial into its larger dataset.

This is all to the good, but labeling this as a RECOVER trial is a bit misleading. Still, this is a great trial that may be unique in the amount of resources devoted to it in the long-COVID field.

An intense and “high-touch” study, the patients are followed monthly for six months (CPET, cognitive testing) and have a 12-month follow-up. A major focus on understanding downstream effects will occur. Besides a heavy emphasis on cardiopulmonary exercise testing (good for RECOVER!), the trial will feature autonomic functioning assessments, plasma and blood analyses, and a subset of patients will get an expanded workup, including lumbar punctures, cerebrospinal fluid analyses, and brain MRIs. Thus far, the long-COVID patients have been eager to engage in the more invasive procedures.

The University of California at San Francisco, Emory University, the University of Minnesota, and Vanderbilt University are all recruiting, and 11 more sites (from RECOVER) will be announced. Patient advocacy paid off when RECOVER agreed to include a cohort of long-COVID patients who became infected before the development of standard diagnostic tests.

If I had long COVID, this would be the trial I would want to get into.

Enrolment into the 550-person trial is expected to be complete not this year, or next year, but in 2027 (!!!). They expect “topline results” to be available shortly after complete enrolment, so we should have an update in about a year and a half. (This is how things often go, in NIH land: study gets funded in 2024; enrolment complete in 2027; full paper in 2028?)

One can understand why RECOVER would want to assist this mammoth study but with so many other treatments that need consideration, it was another conservative choice. There’s clearly a lot of interest in this treatment. Let’s hope that RECOVER and others have guessed right.

Side Note: the Charles Vallee Story

“What frustrated us with Charlie is that there just didn’t seem to be any place to go,” his father, Rodolphe “Skip” Vallee.

The Charles M Vallee Biorepository, which will house all the plasma, serum, PBMC, and CSF specimens, was created in honor of Charlie Vallee, whose story should be known.

An extraordinary individual and high achiever, Charles Vallee was on an upward path when he ran into long COVID. One could have envisioned him reaching high posts in the military or State Department. His story demonstrates how quickly even the best of us have been laid low by long COVID.

Charles Vallee began his academic career with a degree in International Affairs and four years of Arabic studies. Internships in Israel, at General Keane’s Institute for the Study of War, and the Washington-based Center for Strategic and International Studies in the Transnational Threats Group, followed.

Next, he joined the Defense Intelligence Agency as an intelligence officer attached to the Special Operations Command, and was awarded the Civilian Employee Of The Year award. From there, he transferred to Department of Defense’s Defense Intelligence Agency.

In 2022, at the age of 28, he came down with a severe case of long COVID. He experienced tremor, involuntary and uncontrollable shaking of the extremities, persistent and debilitating headaches, inability to sleep, and relentless and unforgiving brain fog that rendered even basic household tasks difficult. Social interactions became awkward, and reading and recall—the bread and butter of his job—became nearly impossible.

He received a medical leave, but the disease took its toll, and with no hope in sight, three months later, he took his life. Charles’s story demonstrates how easily these diseases can quickly take even the best and brightest of us down.

It also shows how far reaching it can be. Charles Vallee had done defense work in Jordan; he was tasked to go to Iraq when he got sick. Reading about Charlie, I would venture to say that depression had not been an issue for him until long COVID. These diseases can affect us in so many ways…

Going for the Gusto: the GLP-1 Agonists

Dr. Kaufman led off the talk on GLP-1 agonists. A couple of months ago, Dr. Kaufman (and Dr. Ruhoy) said they’d be back with more data on how their patients were doing on GLP-1 agonists – and here we are.

First, Dr. Kaufman underscored the need. Of the approximately 150 long-COVID patients he’s seen, 70% are home or bedbound. Lives have been completely overturned. He emphasized that many people in the prime of their lives – all of whom meet the criteria for ME/CFS – have had their lives overturned.

Kaufman noted that he works with a group of about 800 practitioners on a listserv who bounce ideas and results off of each other.

Twice he noted that although they can make patients better, they are still incredibly ill. They can help with mast cell issues and POTS, but they still have trouble moving the needle of fatigue and pain.

Upon receiving an email from the listserv group about a patient who had transitioned to a GLP-agonist for weight loss and subsequently experienced no anaphylaxis episodes, with rapid improvement in generalized pain and inflammatory symptoms (including neurological and cognitive issues), he was intrigued.

That email started a tsunami of discussion and a great deal of trial and error with these drugs. A recent survey of the group found that of about 350 patients given microdoses, 60-90% of patients responded with decreased fatigue, brain fog, pain, and MCAS symptoms. The improvements usually show up in 1-4 weeks.

idea spreads

As the word, spread more and more doctors on the listserv began using GLP-1 agonists.

Over time, the group has found that Tirzepatide (Mounjaro; Zepbound) gives the best effects. Dosing begins at 1/10th to 1/5th of the usual starting dose and then is titrated up in 0.25 mg increments. Even at .25 mg, some patients report benefits. The maximum dose is 1.25mg-2.5 mg (Kaufman stops at a lower dose primarily because he doesn’t want patients to lose weight.) With Kaufman now often recommending it early to patients, Mounjaro is clearly becoming a cornerstone of his practice.

At the low doses, the drug has been remarkably well tolerated.

Since the drugs are only available in higher doses, the patient draws the dose out of a vial and injects it using an insulin syringe. Kaufman said that being able to help with systemic symptoms like fatigue and pain constitutes a huge change compared to, say, improving blood pressure with midodrine.

NIH has not decided on a drug, dosing, etc., but all the experts have been assembled and they are beginning to work on the protocols.

Conclusion – the news on GLP-1 agonists continues to be good, and RECOVER knocked it out of the park with this choice. Despite having only case and anecdotal reports, RECOVER showed flexibility and proactiveness we haven’t seen before as it responded to a rapidly emerging finding that may make a real difference. This will likely be a smaller, mechanistic trial that probes more deeply into the physiological effects GLP-1 agonists are having.

The Surprise – the Stellate Ganglion Blockade Makes the Cut

RECOVER scores again with a surprise choice – stellate ganglion blockade.  Dr. Bombardieri, Clinical Associate Professor in Stanford, noted that downregulation of the parasympathetic nervous system (PNS – “rest and digest”) and upregulation of  the sympathetic nervous system (fight or flight) SNS exists in long COVID. By temporarily blocking sympathetic nervous system outflows, it may be possible to restore normal SNS activity; i.e., given a chance to reset, the system may be able to proceed normally.

The procedure is very simple: block sympathetic nervous outflows by injecting an anesthetic into the stellate ganglion in the neck which regulates sympathetic tone and blood flows in the head, neck, and trunk region.

The stellate ganglion arises when the first thoracic and inferior cervical ganglia fuse together – which occurs in about 80% of the population. Injecting local anesthetic near the stellate ganglion can tamp down that activity of the entire cervical sympathetic chain that regulates the top third or so of the body.

There’s nothing new about it: it’s been used in various ways for over 70 years. A 2014 study (n=166) found that monthly SGB injections for 3 months provided clinically meaningful results in military personnel with PTSD for at least 6 months.

Interestingly, SGB appears to be able to improve sleep by reducing inflammation, increasing melatonin levels, and increasing blood flows. In animals, it improved cognition by inhibiting the TLR4/NF-κB pathway, which some believe may play a key role in ME/CFS. SGB also suppressed the stress and inflammation response, and helped recalibrate nerve-immune system dysfunction in people with traumatic brain injury.

Liu and Duricka proposed that SARS-CoV-2 infection may result in “remodeling of the neuroimmune interface including the stellate ganglion”. Indeed, they write that the satellite glial cells which envelop sympathetic ganglia, “together comprise a functional neuroimmune unit.”. Like Dr. Bombardieri, they propose that SGB may “re-establish homeostasis between the autonomic nervous system and the immune system,” i.e., reset the interaction between the ANS and immune system. (The ANS is an important immune system regulator.)

The development of ultrasound allows the blockades to be produced safely and effectively. The practitioner can clearly visualize the arteries, veins, etc., and can watch the needle as it goes in and injects the anesthetic. The blockades can be done on the right or left sympathetic nerve ganglion. The “minimally invasive” procedure is very safe, but Dr. Bombardieri emphasized that the anesthesia needs to reach a specific spot and should be done by a practitioner with “specialized training”. She called it a “minimally invasive” procedure.

While the procedure is safe, it temporarily produces something called Horner’s syndrome (drooping eyelids, reduced pupils, and reduced sweating) on the side where the injection is done. (Horner’s syndrome is an indication that the procedure worked).

Dr. Bombardieri believes the block does what it does by improving blood perfusion to the brain (vasodilation) and by reducing neuroinflammation. (It would be great to have this done while using the Lumia device to assess blood flows to the brain.)

Her 2022 overview paper found 16 small SGB studies involving 224 patients. Only one was placebo-controlled. Consistent relief of fatigue and brain fog was found. SGB had variable benefits with depression, and consistent improvement was seen in autonomic symptoms, including exercise.

Dr. Luke Liu, cofounder of Neuroversion, was the first to bring attention to the possibility that SGB may help with long COVID in early 2022. Liu reported that he’s performed more than 18,000 stellate blocks.

He started using SGB in long COVID in 2021. After he and Deborah Duricka at Neuroversion saw home run after home run, they published their 2022 case report. In 2024, they published a retrospective case analysis of 33 LC (long-COVID) patients which found that most patients reported symptom improvement within 24 hours, which was sustained for at least a month in about a third of patients.

The 2025 Solve M.E.-Funded SBG Study – Did it Make the Difference?
Tipping point

Solve M.E.’s small but more rigorous study came at a good time. Did it tip the RECOVER team to move forward SGB?

In a recently published Solve M.E.-funded prospective study, Duricka and Liu found that bilateral SGBs (done on both sides of the neck), done for three weeks in long-COVID patients with ME/CFS, produced improvements in PEM, unrefreshing sleep, cognitive Impairment, and orthostatic intolerance. Plus, the SF-36 measures of vitality, physical function, and social function improved significantly. It was particularly good to see improvements in the physical functioning score, as that suggested that the ME/CFS long-COVID patients were doing more.

In fact, by the second follow-up, all the participants rated their physical functioning as “normal”. Seven of the nine individuals no longer met the IOM diagnostic criteria for ME/CFS at long-term follow-up 2 months later. A NASA lean test indicated that POTS had resolved in 3/4 participants. Sleep fragmentation and sleep apnea did not improve but unrefreshing sleep did.

I imagine that this small study went a long way to convincing RECOVER to launch the SGB trial.

Back to Dr. Liu’s Presentation

Dr. Liu showed a video of a young girl so debilitated that, before the procedure, she was flat on her back and had trouble forming words. Ten minutes later, she sat up, looking like a normal young girl. After a right side blockade, her right side was normal, while on the left side she felt a little sluggish.

The next day, a left side stellate ganglion block resulted in both sides moving normally. This person, who had a really good outcome, was still perfectly fine for at least three months. A video showed her ice skating with her dog.

Kyle Kitsmiller – Next, Kyle Kitsmiller, the husband of a woman who was bedbound for 2 1/2 years, talked. He reported the only improvement in her health came after getting the stellate ganglion block.

Within about 20 minutes of getting a right-sided block, she said her depression and anxiety were gone. Her mast cell problems diminished, and she was able to dramatically expand her diet, from about 7 items to being able to eat a Thanksgiving dinner. Her husband called it a remarkable experience.

In the Q&A period, a doctor reported that his patients were not getting such consistent results. Noting that SGB is getting more and more popular, Dr. Bombardieri emphasized that skilled/trained practitioners are a must. Interestingly, she also reported that blocks can be applied in other areas of the body, affecting the gut, legs, and other areas.

Discussions of study design, patient outcomes, duration, etc., are underway. This will likely be a smaller, more mechanistic trial that probes more deeply into the physiological effects SGBs are having.

Conclusion

SGB was an inspired choice by RECOVER. Perhaps no treatment is in more need of being studied in an organized and rigorous fashion, and that’s what RECOVER will bring to it.

Just Four Trials? Is Funding an Issue?

Money squeeze

Just four clinical trials for a population that needs so many? Is RECOVER in a money squeeze?

The fact that RECOVER TLC is only adding four clinical trials, one of which allows another trial to use its clinical network, suggests that, despite the $500 million infusion from the Biden administration, the treatment arm of the RECOVER Initiative is running out of funds.

Joesph Breen said RECOVER-TLC originally planned for “at least two large pivotal trials and then at least four [smaller] mechanistic studies”.

The fact that it could only produce one pivotal trial (LDN) and two mechanistic studies (GLP-1, SGB) (as well as supporting the Baricitinib trial) suggests that the biggest problem facing RECOVER TLC right now may be a lack of money. It’s leaving a lot of possible treatments on the table.

David Putrino, the director of the Cohen Center for Recovery from Complex Chronic Illnesses at Mount Sinai (CoRE) wrote, “In my opinion, there are a lot of promising targets that have not been explored yet, and we need to be casting a wide net with available resources and gathering as much data as possible, not duplicating efforts.”

Plasmapheresis, the nicotine patch, methylene blue, combination antivirals, many immunomodulators, the list of possibilities go on and on and on. RECOVER has mostly chosen well, but it’s also thrown all its (possibly rapidly disappearing) eggs into one small basket.

Perhaps because it emptied its coffers on the first round of underwhelming treatment trials, RECOVER’s reach is declining just as it shifted to a better course. (Don’t you hate when that happens?) At some point, we need RECOVER to give a return on investment (ROI) on the immense amount of funding (for these diseases) that it’s received. My guess is that it won’t be good.

RECOVER TLC – 1: Ongoing Clinical Trials Update

Over 100 clinical sites tested the interventions from the first round of RECOVER trials. Blood was stored for use in later mechanistic studies (if they occur).

  • Cognitive neuro (n=328) – brain training, goal management, tDCS, paper due soon
  • Vital (n=964) – Paxlovid.
  • RECOVER Autonomic (n=381) – people with severe POTS got IVIG; people with moderate POTS – Ivabradine; in follow-up phase: due in 2026.
  • RECOVER Sleep (n=@1,000) – Sunosi, melatonin, modafinil, Light therapy; enrollment due to complete in Dec 2025; expect a paper by the end of 2026.
  • RECOVER Energize (n=600) – structured pacing for those with PEM, personalized cardiac rehab for others; ending up Dec 2025.

All results are expected by end of 2026.
