The dispatches from certainly one of India’s most troubled generic drug makers had been contrite, crammed with far-reaching guarantees to scrub up its manufacturing unit, cease contamination and ship secure medicine to Individuals relying on the corporate’s medicine.
“We have now began addressing FDA issues very aggressively and comprehensively,” an government from Solar Pharma wrote to the U.S. Meals and Drug Administration in 2015.
“Solar is guaranteeing the presence of a powerful, unbiased high quality unit,” the corporate repeatedly pledged.
An FDA inspection in 2014 had turned up harmful violations at Solar’s manufacturing unit within the Indian metropolis of Halol, and the main points had been grim: Managers weren’t following fundamental guidelines to stop the contamination of injectable medicine. They’d failed to find out whether or not “unknown impurities” present in medicine had been poisonous. The manufacturing unit itself was in disrepair. The ceiling leaked and investigators noticed dripping water, one other harmful contamination threat, amassing in buckets in a sterile manufacturing space.
Solar vowed daring reform on the manufacturing unit, its flagship for the U.S. market. In a collection of letters to the FDA after the inspection, executives described an extended record of “enhancements” in amenities, in staffing, in high quality requirements, in coaching.
However for eight years, as inspectors returned and found time and again that Solar’s efforts had been grossly insufficient, the FDA did little to warn the general public or cease the medicine from coming to the US.
The trove of Solar correspondence obtained by ProPublica offers a uncommon glimpse into non-public discussions between the worldwide drugmaker and the U.S. regulator singularly accountable for defending customers from unsafe medicine. The paperwork present how usually the FDA tolerated Solar’s damaged guarantees and substandard manufacturing, permitting an uninterrupted circulation of generics to an American public clamoring for cheaper medicine.
As Solar’s fixes fell quick, the company in 2015 even declared the manufacturing unit’s merchandise “adulterated” which, in accordance with federal regulation, means they had been produced in a manner that would have compromised their power, high quality and purity.

Not till the ultimate weeks of 2022 would the company bar the manufacturing unit from transport its medicine to the U.S. Even then, regulators instantly excluded greater than a dozen drugs from the ban. The exemptions allowed Solar to proceed sending these medicine — with few restrictions and no common testing by the FDA.
In June, 11 years after that first alarming inspection, the company went again to the manufacturing unit and chronicled virtually an identical deficiencies. Tools was nonetheless soiled. Injectable drugs nonetheless had impurities. One employee wasn’t carrying clear gloves.
The failings satisfied the FDA to maintain the import ban in place, however the company continued to permit Solar to ship exempted medicine to the US.
“Would you belief any individual who repeatedly lies to you?” mentioned Dinesh Thakur, an business whistleblower and drug-safety advocate. “I don’t know how one can justify your choice to attempt to give them a move each time. … You’re mainly placing folks in danger.”
Greater than 20 international factories banned from the U.S. market have acquired related exemptions from the FDA since 2013 by way of a little-known apply utilized by the company to stop drug shortages. ProPublica reported in June that antibiotics, anti-seizure medicine and chemotherapy therapies had been shipped from these crops even after inspectors recognized vital violations in the best way medicine had been made. In all, greater than 150 medicine or their substances acquired exemptions.
And, similar to with Solar, the FDA by no means shared the main points with the medical doctors prescribing the drugs or the sufferers taking them. (ProPublica compiled a record of exempted medicine and substances since 2013.)
The company didn’t reply to questions concerning the Solar manufacturing unit, the choice to attend eight years to impose the ban or the exemptions that adopted, saying solely it couldn’t talk about potential or ongoing compliance issues. The FDA referred additional inquiries to Solar.
The FDA additionally didn’t reply immediately whether or not it believed that medicine exempted from Solar’s Halol plant and the opposite factories had been secure. To “assist guarantee shopper security,” the company mentioned, firms are required to topic exempted medicine to additional testing with third-party oversight earlier than the drugs are despatched to the US.
ProPublica’s evaluate of the FDA’s personal data, nevertheless, reveals the potential weak point of such a system. Among the firms had been caught offering unreliable testing data to the FDA earlier than they acquired exemptions. FDA inspectors have discovered managers at Solar’s Halol manufacturing unit repeatedly disregarded the outcomes of assessments exhibiting medicine had been tainted with impurities. In 2019, inspectors additionally found that Solar staff might entry laptop techniques with out oversight and edit microbiological take a look at outcomes to doubtlessly decrease troubling findings.
“All the inspectors I do know who do inspections in India had been conscious of the issues” at Solar, mentioned one veteran FDA investigator who didn’t need to be recognized as a result of they weren’t licensed to talk publicly. “You simply fear concerning the sufferers.”

For the reason that 2014 inspection, FDA data present, the company has acquired 1000’s of reviews from medical doctors and others noting issues concerning the medicine that Solar makes on the Halol manufacturing unit and at different crops. The complaints described potential contamination and different high quality points, or sufferers who had skilled sudden or unexplained well being issues. The FDA cautions that the outcomes within the reviews might haven’t any connection to the medicine or may very well be surprising uncomfortable side effects. Drug security specialists say there isn’t any technique to know for positive with out additional research.
Solar didn’t reply to detailed questions on its regulatory historical past. In an electronic mail, the corporate mentioned it has upgraded the Halol facility and collaborated with manufacturing consultants and is testing to confirm that medicine made there are secure and efficient. Adherence to high quality requirements, the corporate mentioned, “is a high precedence for Solar, and we keep a relentless deal with high quality and compliance to make sure the uninterrupted provide of medicines to our prospects and sufferers worldwide. We proceed to work proactively with the US FDA and stay dedicated to attain full decision of any FDA regulatory points at our amenities.”
Solar has been making that very same promise for years.
Guarantees Made and Damaged
Solar, one of many main exporters of medicines to the US, started its marketing campaign to win again the belief of the FDA shortly after three inspectors in September 2014 traveled to the Halol manufacturing unit in western India and located the worrisome violations.
On the plant, the investigators zeroed in on the manufacturing of injectable drugs. Delivered immediately into the physique, the medicine could be significantly harmful, even deadly, when contaminated. However the manufacturing unit, inspectors discovered, had no procedures to stop the contamination of sterile medicine, in accordance with the report.
One month later, Solar wrote to the FDA, saying it had introduced on consultants to handle high quality points, develop coaching applications and conduct audits of the manufacturing unit.
“We take very significantly every of the problems that FDA has raised,” the corporate wrote. “Solar understands the issues … and absolutely appreciates the necessity for a whole and complete response and a sturdy compliance enhancement plan to handle these issues.”
The letter was despatched by two Solar vice presidents — one the pinnacle of high quality, the opposite accountable for international manufacturing. They dedicated to sending a written replace each different month, starting in December that yr, about modifications for “long-term compliance.”
By February 2015, in its second replace to the FDA, Solar touted greater than 120 fixes on the manufacturing unit. However primarily based on its earlier inspection, the FDA nonetheless issued a warning letter, which referred to as the manufacturing unit’s medicine “adulterated.”
“It’s important that government administration systematically enhance their oversight of producing high quality,” the company admonished within the December 2015 letter.
The corporate shortly responded, dispatching executives to FDA headquarters in Maryland to ship private assurances that the manufacturing unit was falling in line. “We appreciated the chance to debate Solar’s substantial progress,” two of the corporate’s high quality managers wrote after the January 2016 go to. “Solar stays centered to ship substantial enhancements.”
Solar pledged to spend $218 million on facility enhancements, in accordance with certainly one of its letters to the FDA. However inspectors in 2016 turned up extra issues. As soon as once more, Solar promised reform and detailed the steps it could take to repair violations.
This time, Solar sought to reassure the FDA concerning the manufacturing of a generic drug, carbidopa and levodopa, used to deal with tremors and different results of Parkinson’s illness. Among the manufacturing unit’s tablets weren’t dissolving correctly when ingested, in accordance with a Solar letter that yr. That would have left sufferers with too little of the important thing ingredient wanted to manage the illness, or an excessive amount of of it.
Solar informed the FDA that an inside evaluate was underway and the corporate would assess every other medicine with related high quality points. Solar quickly recalled 8,500 bottles of the drug in the US.
Extra letters from Solar adopted in 2017, some addressed on to Carmelo Rosa, a longtime director of high quality on the FDA’s Heart for Drug Analysis and Analysis, which oversees drug security. The company didn’t reply to a request for remark from Rosa, and Rosa didn’t reply to an electronic mail or LinkedIn message.
Inspectors went again to the manufacturing unit in February and August 2018, unearthing extra issues. In December that yr, inspectors visited once more — this time as a result of Solar wished to introduce three new injectable drugs into the U.S. market. The inspectors famous that earlier issues had been corrected, data present.
However only one month later, Solar recalled 135,000 vials of vecuronium bromide, a muscle relaxer used throughout surgical procedure, saying glass particles had been discovered and will trigger life-threatening blood clots. The corporate on the time mentioned it had not acquired any reviews of hurt.
Inspectors went again to the manufacturing unit two extra occasions in 2019, as soon as in June and once more in December, and located extra issues with the best way injectable drugs had been made. The December inspection was so alarming that the FDA held an pressing teleconference with the corporate, in accordance with data obtained by ProPublica, which final yr sued the company in federal courtroom to realize entry to the data.
Regardless of the issues, one other FDA group — tasked with stopping drug shortages — reached out to Solar after the inspection to ensure that the manufacturing unit would proceed to supply the most cancers drug doxorubicin. Solar promised it could.
The data present that for a collection of necessary discussions with Solar, the FDA excluded the group that oversaw the inspections on the manufacturing unit and had been finest knowledgeable about what was occurring there.
“It could have been very useful” to have the inspection division “plugged in from the start,” one group member emailed colleagues and his administration within the months after the inspection.
Round that point, the corporate quickly shut down the manufacturing unit’s sterile manufacturing line, in accordance with an electronic mail that Solar despatched to Rosa. The plant was making 16 injectable medicine for the U.S. market.
Early the following yr, Solar assured Rosa that it had executed intensive opinions and submitted a method to once more ship injectables to the US.
That included testosterone, which is used to deal with every thing from low libido to bone well being. However when sufferers received their bottles, some took to social media to explain the looks of surprising crystals.
“They gained’t go away, is it okay to make use of?” one particular person posted on Reddit in 2021. “I must do my shot in the present day.”

Crystals in testosterone vials aren’t uncommon, and Solar and different producers embrace directions on the label to do away with them by warming the product. FDA inspectors, nevertheless, went again to the manufacturing unit in Halol in 2022 and located that Solar had acquired a whole lot of complaints concerning the crystals, together with two that famous it took greater than 5 hours to dissolve them when it ought to usually solely take minutes.

Solar mentioned it had investigated the issues and concluded the testosterone was acceptable. However the firm couldn’t present documentation that confirmed staff had been correctly skilled or certified to run the assessments and finally couldn’t produce information confirming the crystals correctly dissolved, the FDA discovered.
Inspectors issued one other damning report. Six months later, in December 2022, the FDA assessed its hardest penalty: banning the Halol manufacturing unit from transport medicine to the US. The transfer got here eight years after Solar began pledging reforms. And the FDA then undercut its sanction by shortly exempting greater than a dozen medicine from the ban.
Within the newest inspection in June of this yr, inspectors discovered the manufacturing unit failed to research micro organism present in take a look at vials, disinfect manufacturing areas and tools or correctly deal with vials and stoppers meant for sterile drugs, in accordance with the report.
Although the FDA printed on its web site warning letters despatched to the manufacturing unit, it has by no means alerted the general public concerning the issues in a complete manner or supplied a listing of the medicine made there. The names of Halol’s merchandise are blacked out on inspection reviews so customers can’t test their drugs and make knowledgeable selections about whether or not to take them.

“Your loved ones members are taking these medicine, and are they secure? Nicely, possibly, properly possibly not,” mentioned former FDA inspector Patrick Stone, who now advises pharmaceutical firms. “The FDA turns a blind eye. In case your market [share] is sufficiently big, then you definitely get leeway.”
Blind Religion
In 2023, Solar’s billionaire founder mentioned the introduction of recent merchandise and positive factors in market share made the corporate properly positioned to “exploit the expansion alternative within the U.S. market.”
Regardless of the lengthy record of vital inspection reviews, 5 medicine made at Solar’s Halol manufacturing unit are nonetheless allowed into the U.S. 2 1/2 years after the FDA issued the import ban. The exempted drugs are vecuronium bromide and doxorubicin, in addition to: divalproex delayed launch tablets, that are used to deal with seizures and migraines; leuprolide injections, that are utilized by folks with prostate most cancers, endometriosis and different circumstances; and temozolomide capsules, which deal with mind most cancers.
Present and former FDA inspectors and others mentioned the company ought to have acted quicker, responding to the issues its inspectors uncovered moderately than shopping for into Solar’s assurances.
One senior FDA worker conversant in the inspections mentioned they feared the corporate didn’t have the know-how to make secure medicine.
“Is it that they’re attempting to cover stuff? Is it that they’re attempting to guard? Or is it that they haven’t any clue methods to be doing this stuff?” mentioned the staffer, who declined to be recognized as a result of they weren’t licensed to talk publicly. “Why would you get on the telephone with FDA and brag that you’ve all these techniques in place and also you didn’t?”
The adversarial occasion reviews concerning the firm’s medicine submitted to the FDA over time describe choking, vomiting and blistering, or say that the medicine doubtlessly brought on or contributed to “toxicity,” cardiac arrest and renal failure, amongst different reactions, authorities data present. A whole bunch of the complaints describe drugs with attainable contaminants, medicine that didn’t dissolve correctly and different high quality and security issues.
Solar’s testosterone alone was the topic of greater than 500 reviews, together with ones describing swelling, elevated coronary heart fee, burning sensations or ache, amongst different signs, data present.
At present, years after investigators first recognized issues, the senior FDA worker mentioned the specter of hurt lingers.
“The folks on the opposite finish have religion that the merchandise they’re taking are secure and efficient,” mentioned the staffer. “I consider the faces. I consider my dad and mom. … I consider the customers who’re mainly taking these medicine on blind religion.”
