“I'm not great at the advice. Can I interest you in a sarcastic comment?”

This is what ‘Friends’ actor Matthew Perry’s character Chandler Bing was known for. He was known for being funny. However, he had his own struggles in his personal life and those struggles were acute depression. He was treating it with ketamine infusion therapy which is legal in the US and the UK.

What is Ketamine infusion therapy?

Ketamine is an anaesthetic used to treat depression, anxiety and pain under supervised and controlled medical settings. However, it does have its side effects, which can lead to distortion of sight, sound and time. It can also produce calming and relaxing effects.

Ketamine increases a person’s heart rate and blood pressure. If overdosed, it can leave users confused and agitated and can cause them to hurt themselves without even realising it. It can also lead to liver damage and bladder problems.

However, when used in moderation and under the supervision of medical doctors, it can treat depression where traditional antidepressants have failed.

Prof Rupert McShane, a University of Oxford psychiatrist who runs an NHS ketamine treatment clinic told BBC that ketamine “probably turns off the area of the brain that is involved in disappointment.”

Can Ketamine Infusion Therapy Kill Someone?

In simple terms, it cannot, be if the dosage is given in a controlled setting and as prescribed. Ketamine infusion therapy uses drugs in small doses than those used for anaesthesia. It acts faster than traditional anti-depressants, but the effects also wear off way quickly. Which is why it is important to monitor patients’ mental state for relapsing back into depression and discouraging them from overdosing on it.

There are ways of giving people ketamine. One of the ways is through “infusing”, which means to use an IV drip. However, injections, nasal sprays and capsules are also methods used to give people ketamine.

Since the dosage of ketamine used in the infusion treatment is small, it being the reason of actor Perry’s death was ruled out. The medical examiner also noted that Perry’s last ketamine infusion therapy session happened more than a week before his death, which means by the time he had died, it must have worn off.

So, What Happened To Perry?

Though Perry’s last session was more than a week before, his post-mortem showed that his blood contained a high concentration of ketamine. He had died of the “acute effects” of ketamine.

If it was not his session, then how did he get ketamine?

Prosecutors alleged that his assistant gave him at least 27 shots of ketamine in four days before his death, reported BBC.

Perry has been open about his personal struggles and this is what the doctors and dealers used against him. Martin Estrada, the US attorney for California’s Central District told the BBC that people took advantage of his condition. They charged him 165 times more than what vials of ketamine cost.

Names that have come up include Dr Salvador Plasencia, drug dealers “Ketamine Queen” aka Jasveen Sangha and Eric Fleming, and Perry’s live-in assistant Kenneth Iwamasa.

Who Are These Names And What Did They Do?

Ketamine Queen or Sangha supplied drugs that led to Perry’s death. Her home was a “drug-selling emporium,” said Estrada. More than 80 vials of ketamine, and thousands of pills including methamphetamine, cocaine and Xanax were allegedly found in her house known as the “Sangha Stash House.”

Sangha is known to deal with high-end celebs and was a “major source of supply for ketamine to others as well as Perry,” said Estrada.

Dr Plasencia called Perry a “moron” while charging him $2,000 for vials that cost only $12. He sold Perry 20 vials of ketamine between September and October 2023, costing $55,000.

He was the one who taught Iwamasa, who had no medical knowledge to inject the drug. This is after he knew that “Perry’s ketamine addiction was spiralling out of control,” as per what the investigators told the BBC.

Another dealer Fleming was told by Sangha to “delete all our messages.” While Fleming pleaded guilty to conspiring to distribute drugs unlawfully, he also allegedly messaged Sangha: “Please call...Got more info and want to bounce ideas off you. I’m 90% sure everyone is protected. I never dealt with [Perry] only his assistant. So the assistant was the enabler.”

The court documents also revealed that he asked Sangha on whether the ketamine stays in your system or “is it immediately flushed out.”

Dr Pepper, Bots, Cans

The people who allegedly exploited Perry used coded language for ketamine and called it “Dr Pepper”, “bots”, or “cans.”

Selling overpriced drugs, taking advantage of Perry’s mental condition and falsifying medical records to make the drugs given to him look legitimate by Dr Plasencia is what took Perry’s life.

Iwamasa is said to have administered more than 20 shots of ketamine and three on the day Perry died. Whereas ketamine is only administered by a physician. Authorities also found that weeks before Perry’s death, Dr Plasencia allegedly bought 10 vials of ketamine and intended to sell to Perry.

He also injected Perry with a large dose, two days later. This caused him to “freeze up” and spiked his blood pressure.

When I Die, I Want Helping Others To Be The First Thing That’s Mentioned

Perry had always been open about his drug addictions, struggles with alcohol and his depression. He said that his openness would help others who are also struggling and wanted to be remembered by his quote which also is on the homepage of the Mattew Perry Foundation that helps others struggling with the disease of addiction: “When I die, I want helping others to be the first thing that’s mentioned.”

Five arrests have been made in the case so far.

Medicine safety must become everyone’s responsibility, the Indian government said today while launching the Biovigilance Program to monitor adverse events linked to organ and tissue transplantation.

Under the program, the Indian Pharmacopoeia Commission (IPC) will lead efforts to strengthen the reporting, assessment, monitoring and prevention of adverse events associated with medicines and biological products used in organ and tissue transplantation, including products administered to donors and recipients.

Together, pharmacovigilance, materiovigilance and biovigilance initiatives will strengthen safety monitoring across medicines, medical devices and transplant procedures.

The program was launched by Union Minister of State for Health & Family Welfare and Chemicals & Fertilizers Anupriya Patel at the 6th National Pharmacovigilance Week organized by the IPC at Dr. Ambedkar International Centre in New Delhi.

New Medicine Safety Initiatives

Patel also launched initiatives to help healthcare professionals make informed, evidence-based decisions when prescribing and using medicines. These include:

• The 7th Edition of the National Formulary of India (NFI),
• The Guidance Document for Hospitals in India for Safety Monitoring and Reporting of Medical Device-Related Adverse Events,
• The ADR-PvPI 2.0 Mobile App for iOS users.

“Rational use of medicines and continuous safety monitoring are integral to public health,” said Patel. She added that “every patient must receive the right medicine, of assured quality, in the right manner and with the highest possible degree of safety”.

“The NFI serves as an important bridge between scientific standards and clinical practice, guiding healthcare professionals in the appropriate and rational use of medicines,” Patel said.

India’s Pharmacovigilance Network

Patel emphasized that medicine safety is a continuous responsibility—from the development and manufacture of a drug or medical device to its prescription, dispensing, use and post-market monitoring.

She also highlighted the country’s progress in pharmacovigilance, noting that “India has built a strong indigenous ecosystem capable of generating, collecting, processing and analyzing medicine-safety data from across the country”.

India has moved from the 123rd position during 2009–2014 to 8th globally in contributions to the WHO patient safety database, Patel said.

The Pharmacovigilance Program of India (PvPI), coordinated by the National Coordination Centre at IPC, systematically collects, assesses and analyzes adverse drug reaction information. The Materiovigilance Program of India (MvPI) monitors adverse events associated with medical devices.

AI And Patient Reporting

Patel said digital initiatives, including NFI Online, IP Online, ADR-PvPI 2.0 Mobile App and the Adverse Drug Reaction Monitoring System (ADRMS), are making medicine-related information and adverse-event reporting more accessible, transparent and responsive.

She called for greater use of emerging technologies, including artificial intelligence and advanced data analytics, to strengthen medicine-safety systems and enable timely generation and use of safety evidence.

The Minister also stressed the need to increase patient participation in adverse-event reporting. She noted that digital platforms, mobile applications and helplines have made reporting easier, and called for addressing the “missing link” of patient reporting.

"Around 1,150 ADR reporting centers are currently operational across public and private hospitals and medical colleges in the country, along with medical-device vigilance facilities. The government plans to expand these capabilities to the primary healthcare level," Patel said.

India’s Patient Safety Push

Referring to the vision of Viksit Bharat 2047, Patel said patient safety must remain a key national priority. She called for India to build on its position as the “pharmacy of the world” and aspire to become a global leader in pharmacovigilance sciences and patient safety.

“Medicine safety must become everyone’s responsibility. Every single reported event can save a life.”

She said collective participation would be critical to building a strong culture of medicine safety and promoting the rational use of medicines.

An LSD-based treatment has cleared its second Phase 3 trial for generalized anxiety disorder (GAD), sparking hope to bring the first new drug for the condition in nearly two decades closer to FDA approval.

Definium Therapeutics recently said that its drug DT120, a tablet containing lysergide, the pharmaceutical form of LSD, significantly reduced anxiety symptoms compared to placebo in the Panorama Phase 3 trial that included 245 participants.

The company said participants receiving a single 100-microgram dose had a 9.8-point reduction in their score on the Hamilton Anxiety Rating Scale (HAM-A) after 12 weeks, compared to a 4.7-point reduction among those receiving placebo. The difference with placebo was 5.1 points.

The improvement surfaced quickly as differences from placebo seen as early as Day 2 and sustained through the 12-week assessment.

A Promising Second Phase 3 Trial

Panorama is the second positive Phase 3 trial for DT120 in GAD. An earlier Phase 3 study, called Voyage, also found a significant improvement in anxiety symptoms, with a placebo-adjusted difference in HAM-A of 5.4 points at 12 weeks.

Phase 3 trials are generally the pivotal studies in any research as they are used to provide evidence of a treatment's efficacy and safety before regulatory review and approval.

Rob Barrow, Chief Executive Officer of Definium Therapeutics, said, “The Panorama results again met our high expectations and confirmed the unprecedented efficacy of DT120 in GAD.”

Barrow added, “With strong positive results across four complementary studies, we have built a compelling body of evidence that increases our confidence in the potential best-in-class profile of DT120.”

The drug also hopes to bridge the long-overdue treatment gap in GAD. Definium says the last new drug approved for GAD was in 2007, meaning DT120 could potentially become the first newly approved GAD treatment in almost 20 years if it ultimately clears regulatory review.

Definium has a pre-New Drug Application meeting with the US Food and Drug Administration planned for the fourth quarter of 2026 and anticipates filing its application in the first half of 2027.

Barrow also said, “Building on this momentum, we are advancing toward an NDA submission and look forward to aligning with the FDA at our upcoming pre-NDA meeting. We are deeply grateful to the participants, investigators, site personnel, and our team whose commitment and hard work made this progress possible.”

LSD-Based Treatment For GAD

DT120 is designed as a single-dose treatment rather than a daily tablet. In the Panorama trial, participants were monitored for at least eight hours after dosing because LSD can temporarily lead to certain cognitive and emotional changes.

Among those receiving 100 micrograms, the average time to meet the study's end-of-session criteria was 6.2 hours, while 94% met those criteria within eight hours.

The treatment works through the serotonin 5-HT2A receptor, although exactly how LSD produces longer-lasting improvements in psychiatric symptoms remains unclear.

The company reported that DT120 was generally well tolerated. It also said that side-effects were mild to moderate, temporary and occurring mainly on the day of dosing.

Among people receiving the 100-microgram dose, common adverse events on dosing day included illusions in 68%, nausea in 37% and headache in 24%. There were no drug-related serious adverse events or signals of increased suicidality in the trial, according to Definium.

It is important to know that these results are reported by the company, and the complete data will need regulatory and scientific scrutiny for the drug’s approval.

Physicist Stephen Hawking lived with amyotrophic lateral sclerosis (ALS) for more than five decades. Diagnosed at 21 in 1963, he was initially given just two years to live. However, his early-onset form of ALS progressed unusually slowly. Hawking died on March 14, 2018, aged 76.

Now, US researchers have developed a personalized RNA therapy for a rare genetic form of ALS and administered it to a single patient. One year after treatment, the patient showed improvements in physical function and a key biomarker of nerve damage.

ALS, also known as motor neuron disease (MND) or Lou Gehrig’s disease, affects nerve cells in the brain and spinal cord that control voluntary movement. As these neurons deteriorate, muscles become progressively weaker and can eventually lead to paralysis.

What Was The New RNA Therapy?

Researchers at the Mayo Clinic developed an antisense oligonucleotide (ASO) therapy, a personalized RNA-based treatment designed to target RNA produced by the mutated gene and reduce the production of specific proteins.

Unlike conventional gene therapy, which aims to alter a person's genetic material, ASO therapy uses short strands of genetic material called “oligonucleotides,” to target RNA, according to the findings, published in the international journal Med.

These oligonucleotides prevent the production of the proteins that cause ALS.

It was administered on the male patient who had slowly progressive ALS, with onset in his right shoulder in 2020. In 2018, he underwent a spine surgery for radiating left neck and arm pain with mild weakness.

It was in 2021 that he was diagnosed with ALS caused by a mutation in the CHCHD10 gene, found in fewer than 1% of people with hereditary ALS.

Defects in CHCHD10 can damage mitochondria, which produce energy inside cells, ultimately contributing to nerve-cell death and ALS.

Patient's ALS Symptoms Improved

The patient received six spinal injections between April 2024 and April 2025. The first three doses were 50 milligrams each, followed by three 75-milligram doses.

One year after the first dose, the patient's blood levels of neurofilament light chain (NfL) had fallen by about 50% and returned to the normal reference range.

NfL is a protein released when nerve cells are damaged and is used as a biomarker of neurodegeneration and ALS progression.

The patient's score on the Revised ALS Functional Rating Scale (ALSFRS-R) also increased from 33 to 36 over the year. The scale measures physical function in people with ALS.

Other measures of breathing and cognition remained stable, and the patient showed no signs of cognitive decline during the reported follow-up.

"To date, the ASO has been well tolerated, with a good safety profile, and has demonstrated early signs of efficacy. The patient reports subjective improvement, and our primary response biomarker, neurofilament light (NfL), has normalized," the research team wrote in the paper.

The patient’s symptoms improved one year after receiving the drug, and he continues to work as a physician, Nature reported.

“We have shown that it is possible to develop a personalized ASO therapy for CHCHD10-related ALS,” adding that this provides “evidence suggesting the potential for therapeutic benefit in the clinic,” the research team stated.

Is This A Cure For ALS?

The findings are an early step, and it is far too soon to know whether the treatment can stop ALS progression or provide a cure.

The patient will need to be monitored for several more years, while the therapy must also be tested in additional patients to determine whether the improvements can be sustained and whether the treatment can slow disease progression.
