Johnson & Johnson announced that its Imbokodo Phase IIb trial in HIV failed to hit the primary endpoint. The study evaluated the company’s investigational HIV vaccine regimen in young women in sub-Saharan Africa at high risk of acquiring HIV. It did not provide sufficient protection against HIV. The virus uses an adenovirus design that the company also uses for its COVID-19 vaccine.

As a result of the analysis, the Imbokodo trial will not continue. In parallel with the trial, Janssen, a Johnson & Johnson company, is sponsoring the ongoing Phase III Mosaico trial, evaluating a different composition of the HIV vaccine regimen in men who have sex with men (MSM) and transgender individuals. The Mosaico trial is being run in the Americas and Europe, where, the company notes, there are different strains of HIV circulating than in sub-Saharan Africa. After consulting with the Mosaico study’s independent Data and Safety Monitoring Board (DSMB), the company decided Mosaico will continue.

“We are extremely grateful to the women who volunteered for the Imbokodo study, and to our partners, including the people on the frontlines, all of whom are contributing every day to this enduring quest to make HIV history,” said Paul Stoffels, M.D., vice chairman of the Executive Committee and chief scientific officer at Johnson & Johnson. “HIV is a unique and complex virus that has long posed unprecedented challenges for vaccine development because of its ability to attack, hijack and evade the human immune system.”

He went on to say, “While we are disappointed that the vaccine candidate did not provide a sufficient level of protection against HIV infection in the Imbokodo trial, the study will give us important scientific findings in the ongoing pursuit for a vaccine to prevent HIV. We continue to stand in solidarity with people living with and vulnerable to HIV, and remain committed to furthering our research against this devastating virus.”

The Imbokodo Phase IIb trial was a proof-of-concept efficacy study. It began in 2017, was fully enrolled in 2019, and completed dosing on June 30, 2020. It enrolled about 2,600 young women in five countries in sub-Saharan Africa. There were 23 trial sites in Malawi, Mozambique, South Africa, Zambia and Zimbabwe.

The study was supported by a public-private partnership led by Janssen Vaccines & Prevention BV, part of the Janssen Pharmaceutical Companies of J&J. It included the National Institute of Allergy and Infectious Disease (NIAID), the Bill & Melinda Gates Foundation and the HIV Vaccine Trials Network (HVTN). Additional partners that offered support included the U.S. Army Medical Research and Development Command (USAMRDC) and the Ragon Institute of MGH, MIT and Harvard. The South African Medical Research Council (SAMRC) handled implementation in South Africa.

Imbokodo treated participants with four vaccination visits over one year. Then primary analysis was performed 24 months after they received their first shots. The primary endpoint is based on the difference in the number of new HIV infections in placebo versus vaccine groups from month seven through month 24. At the 24-month mark, 63 of 1,109 participants who received placebo acquired HIV compared to 51 of 1,079 in the vaccine group. This had a vaccine efficacy estimate of 25.2%. The vaccine was safe and well-tolerated.

“This high incidence of HIV among young women in sub-Saharan Africa reminds us that, despite great progress made in treatment and prevention, HIV remains a major health challenge for the region,” said Glenda Gray, president and chief executive officer, South African Medical Research Council (SAMRC) and Imbokodo’s Protocol chair. “This underscores the need to apply the knowledge that will be gained from this trial to continue to advance the pursuit of a global HIV vaccine.”

Watch Yield Curve For When Stocks Begin To Price Recession Risk

Authored by Simon White, Bloomberg macro strategist,

US large-cap indices are currently diverging from recessionary leading economic data. However, a decisive steepening in the yield curve leaves growth stocks and therefore the overall index facing lower prices.

Leading economic data has been signalling a recession for several months. Typically stocks closely follow the ratio between leading and coincident economic data.

As the chart below shows, equities have recently emphatically diverged from the ratio, indicating they are supremely indifferent to very high US recession risk.

What gives? Much of the recent outperformance of the S&P has been driven by a tiny number of tech stocks. The top five S&P stocks’ mean return this year is over 60% versus 0% for the average return of the remaining 498 stocks.

The belief that generative AI is imminently about to radically change the economy and that Nvidia especially is positioned to benefit from this has been behind much of this narrow leadership.

Regardless on your views whether this is overdone or not, it has re-established growth’s dominance over value. Energy had been spearheading the value trade up until around March, but since then tech –- the vessel for many of the largest growth stocks –- has been leading the S&P higher.

The yield curve’s behaviour will be key to watch for a reversion of this trend, and therefore a heightened risk of S&P 500 underperformance. Growth stocks tend to outperform value stocks when the curve flattens. This is because growth companies often have a relative advantage over typically smaller value firms by being able to borrow for longer terms. And vice-versa when the curve steepens, growth firms lose this relative advantage and tend to underperform.

The chart below shows the relationship, which was disrupted through the pandemic. Nonetheless, if it re-establishes itself then the curve beginning to durably re-steepen would be a sign growth stocks will start to underperform again, taking the index lower in the process.

Equivalently, a re-acceleration in US inflation (whose timing depends on China’s halting recovery) is more likely to put steepening pressure on the curve as the Fed has to balance economic growth more with inflation risks. Given the growth segment’s outperformance is an indication of the market’s intensely relaxed attitude to inflation, its resurgence would be a high risk for sending growth stocks lower.

Participants in a survey study made a relatively high number of errors when asked to recollect the timing of major events that took place in 2021, providing new insights into how COVID-19 lockdowns impacted perception of time. Daria Pawlak and Arash Sahraie of the University of Aberdeen, UK, present these findings in the open-access journal PLOS ONE on May 31, 2023.

Remembering when past events occurred becomes more difficult as more time passes. In addition, people’s activities and emotions can influence their perception of the passage of time. The social isolation resulting from COVID-19 lockdowns significantly impacted people’s activities and emotions, and prior research has shown that the pandemic triggered distortions in people’s perception of time.

Inspired by that earlier research and clinical reports that patients have become less able to report accurate timelines of their medical conditions, Pawlak and Sahraie set out to deepen understanding of the pandemic’s impact on time perception.

In May 2022, the researchers conducted an online survey in which they asked 277 participants to give the year in which several notable recent events occurred, such as when Brexit was finalized or when Meghan Markle joined the British royal family. Participants also completed standard evaluations for factors related to mental health, including levels of boredom, depression, and resilience.

As expected, participants’ recollection of events that occurred further in the past was less accurate. However, their perception of the timing of events that occurred in 2021—one year prior to the survey—was just an inaccurate as for events that occurred three to four years earlier. In other words, many participants had difficulty recalling the timing of events coinciding with COVID-19 lockdowns.

Additionally, participants who made more errors in event timing were also more likely to show greater levels of depression, anxiety, and physical mental demands during the pandemic, but had less resilience. Boredom was not significantly associated with timeline accuracy.

These findings are similar to those previously reported for prison inmates. The authors suggest that accurate recollection of event timing requires “anchoring” life events, such as birthday celebrations and vacations, which were lacking during COVID-19 lockdowns.

The authors add: “Our paper reports on altered timescapes during the pandemic. In a landscape, if features are not clearly discernible, it is harder to place objects/yourself in relation to other features. Restrictions imposed during the pandemic have impoverished our timescape, affecting the perception of event timelines. We can recall that events happened, we just don’t remember when.

Hyro secures $20M for its AI-powered, healthcare-focused conversational platform

Israel Krush and Rom Cohen first met in an AI course at Cornell Tech, where they bonded over a shared desire to apply AI voice technologies to the healthcare sector. Specifically, they sought to automate the routine messages and calls that often lead to administrative burnout, like calls about scheduling, prescription refills and searching through physician directories.

Several years after graduating, Krush and Cohen productized their ideas with Hyro, which uses AI to facilitate text and voice conversations across the web, call centers and apps between healthcare organizations and their clients. Hyro today announced that it raised $20 million in a Series B round led by Liberty Mutual, Macquarie Capital and Black Opal, bringing the startup’s total raised to $35 million.

Krush says that the new cash will be put toward expanding Hyro’s go-to-market teams and R&D.

“When we searched for a domain that would benefit from transforming these technologies most, we discovered and validated that healthcare, with staffing shortages and antiquated processes, had the greatest need and pain points, and have continued to focus on this particular vertical,” Krush told TechCrunch in an email interview.

To Krush’s point, the healthcare industry faces a major staffing shortfall, exacerbated by the logistical complications that arose during the pandemic. In a recent interview with Keona Health, Halee Fischer-Wright, CEO of Medical Group Management Association (MGMA), said that MGMA’s heard that 88% of medical practices have had difficulties recruiting front-of-office staff over the last year. By another estimates, the healthcare field has lost 20% of its workforce.

Hyro doesn’t attempt to replace staffers. But it does inject automation into the equation. The platform is essentially a drop-in replacement for traditional IVR systems, handling calls and texts automatically using conversational AI.

Hyro can answer common questions and handle tasks like booking or rescheduling an appointment, providing engagement and conversion metrics on the backend as it does so.

Plenty of platforms do — or at least claim to. See RedRoute, a voice-based conversational AI startup that delivers an “Alexa-like” customer service experience over the phone. Elsewhere, there’s Omilia, which provides a conversational solution that works on all platforms (e.g. phone, web chat, social networks, SMS and more) and integrates with existing customer support systems.

But Krush claims that Hyro is differentiated. For one, he says, it offers an AI-powered search feature that scrapes up-to-date information from a customer’s website — ostensibly preventing wrong answers to questions (a notorious problem with text-generating AI). Hyro also boasts “smart routing,” which enables it to “intelligently” decide whether to complete a task automatically, send a link to self-serve via SMS or route a request to the right department.

“Our AI assistants have been used by tens of millions of patients, automating conversations on various channels,” Krush said. “Hyro creates a feedback loop by identifying missing knowledge gaps, basically mimicking the operations of a call center agent. It also shows within a conversation exactly how the AI assistant deduced the correct response to a patient or customer query, meaning that if incorrect answers were given, an enterprise can understand exactly which piece of content or dataset is labeled incorrectly and fix accordingly.”

Of course, no technology’s perfect, and Hyro’s likely isn’t an exception to the rule. But the startup’s sales pitch was enough to win over dozens of healthcare networks, providers and hospitals as clients, including Weill Cornell Medicine. Annual recurring revenue has doubled since Hyro went to market in 2019, Krush claims.

Hyro’s future plans entail expanding to industries adjacent to healthcare, including real estate and the public sector, as well as rounding out the platform with more customization options, business optimization recommendations and “variety” in the AI skills that Hyro supports.

“The pandemic expedited digital transformation for healthcare and made the problems we’re solving very clear and obvious (e.g. the spike in calls surrounding information, access to testing, etc.),” Krush said. “We were one of the first to offer a COVID-19 virtual assistant that deployed in under 48 hours based on trusted information from the health system and trusted resources such as the CDC and World Health Organization …. Hyro is well funded, with good growth and momentum, and we’ve always managed a responsible budget, so we’re actually looking to expand and gather more market share while competitors are slowing down.”
