The Advantages of Flow Cytometry for Counting Bacteria in Probiotics

The Advantages of Flow Cytometry for Counting Bacteria in Probiotics
In 2001, a joint FAO/WHO working group defined probiotics as “live micro-organisms that, when administered in adequate amounts, confer a health benefit on the host.”  Each of the key terms, ‘live’, ‘adequate amounts’ and ‘health benefit’ are, in fact, much debated. Although the health effects of probiotics are implicit in the definition, there are no approved health claims in the EU and, as confirmed in 2018 by the Commission for Health and Food Safety , there is no intention to change this stance. The term ‘probiotic’ itself is forbidden on product labels as it is considered a health claim. ‘Live micro-organisms’ is not without problems either. Traditionally, that means cultivable cells whose amount is expressed in CFU. However, for Marco Pane, R&D manager of Probiotical, a manufacturer of probiotics located in the north-west of Italy, things are not so clear-cut:

In less than a week, in the face of a pandemic, the pharmaceutical sales model changed forever. In-person healthcare provider (HCP) visits came to a screeching halt and brand marketers scrambled to find ways to educate and engage these providers remotely. While the pandemic may have taken us by surprise, we should acknowledge that, even before the pandemic, pharmaceutical sales teams faced significant challenges.

One solution for these challenges is to engage HCPs – virtually.

Tarsier Pharma Raises Capital to Execute Phase-3 Clinical Trial

Tarsier Pharma | August 28, 2021

Tarsier Pharma, a late clinical stage pharmaceutical company focused on the development and commercialization of novel therapeutics to treat patients with blinding ocular diseases, today announced it raised capital to execute a phase-3 clinical trial of its TRS01 program in the US and Europe. Strategic and new investors alongside existing investors participated in this transaction. Following a successful End of Phase II meeting with the FDA, the Company obtained all necessary regulatory approvals to execute phase 3 and has recruited leading uveitis experts as principal investigators. Tarsier plans to enroll the first patient in Q4 of 2021. Tarsier's technology, TRS, is a novel immunomodulator molecule that showed, in a dose-ranging, randomized, double-masked phase I\II trial in the target indication, a prompt and statistically significant improvement in signs and symptoms of uveitis. "We are excited to have the support of our existing and new investors, as we continue our clinical development of TRS01 in advanced stages," said Dr. Haim Langford, CEO of Tarsier. "Looking ahead, we are eager to bring our lead product to market and simultaneously progress our development of important pipeline projects for other back-of -the-eye blinding diseases, and plan to raise additional capital to realize these as well." About Tarsier Pharma Tarsier Pharma is a late clinical stage pharmaceutical company, phase-3 ready, focused on the discovery, development, and commercialization of first-in-class pharmaceutical therapies to treat ocular blinding diseases. TRS is a breakthrough proprietary technology platform, based on a new bio-inspired chemical entity, with novel mechanism of action and demonstrated safety and efficacy in a rare debilitating and blinding indication. Lead product candidate for uveitic glaucoma Non-infectious uveitis is an autoimmune blinding ocular inflammation, considered the third leading cause of blindness in the developed world. Tarsier's TRS01 is a potent fast-acting immunomodulator, delivered as eye drops, for the treatment of non-infectious anterior uveitis in patients with uveitic glaucoma – considered an end-stage condition of uveitis. Once a uveitis patient has also developed glaucoma (uveitic glaucoma), the only available treatments for active inflammation, which are steroids, should be avoided, due to their negative side effects in expediting glaucoma and vision loss. Thus, TRS01 has the potential to become the standard of care for uveitic glaucoma.

PFIZER AND BIONTECH ANNOUNCE VACCINE CANDIDATE AGAINST COVID-19

Pfizer | November 10, 2020

Pfizer Inc.and BioNTech SE today reported their mRNA-based antibody up-and-comer, BNT162b2, against SARS-CoV-2 has exhibited proof of adequacy against COVID-19 in members without earlier proof of SARS-CoV-2 contamination, in view of the principal break viability examination led on November 8, 2020 by an outer, free Data Monitoring Committee (DMC) from the Phase 3 clinical investigation. After conversation with the FDA, the organizations as of late chosen to drop the 32-case between time examination and lead the primary interval investigation at least 62 cases. Upon the finish of those conversations, the evaluable case check arrived at 94 and the DMC played out its first examination on all cases. The case split between inoculated people and the individuals who got the fake treatment shows an immunization viability rate above 90%, at seven days after the subsequent portion. This implies that insurance is accomplished 28 days after the inception of the immunization, which comprises of a 2-portion plan. As the investigation proceeds, the last antibody adequacy rate may shift. The DMC has not detailed any genuine security concerns and prescribes that the examination keeps on gathering extra wellbeing and viability information as arranged. The information will be talked about with administrative specialists around the world. “Today is a great day for science and humanity. The first set of results from our Phase 3 COVID-19 vaccine trial provides the initial evidence of our vaccine’s ability to prevent COVID-19,” said Dr. Albert Bourla, Pfizer Chairman and CEO. “We are reaching this critical milestone in our vaccine development program at a time when the world needs it most with infection rates setting new records, hospitals nearing over-capacity and economies struggling to reopen. With today’s news, we are a significant step closer to providing people around the world with a much-needed breakthrough to help bring an end to this global health crisis. We look forward to sharing additional efficacy and safety data generated from thousands of participants in the coming weeks.” “I want to thank the thousands of people who volunteered to participate in the clinical trial, our academic collaborators and investigators at the study sites, and our colleagues and collaborators around the world who are dedicating their time to this crucial endeavor,” added Bourla. “We could not have come this far without the tremendous commitment of everyone involved.” “The first interim analysis of our global Phase 3 study provides evidence that a vaccine may effectively prevent COVID-19. This is a victory for innovation, science and a global collaborative effort,” said Prof. Ugur Sahin, BioNTech Co-founder and CEO. “When we embarked on this journey 10 months ago this is what we aspired to achieve. Especially today, while we are all in the midst of a second wave and many of us in lockdown, we appreciate even more how important this milestone is on our path towards ending this pandemic and for all of us to regain a sense of normality. We will continue to collect further data as the trial continues to enroll for a final analysis planned when a total of 164 confirmed COVID-19 cases have accrued. I would like to thank everyone who has contributed to make this important achievement possible.” The Phase 3 clinical preliminary of BNT162b2 started on July 27 and has selected 43,538 members to date, 38,955 of whom have gotten a second portion of the immunization competitor as of November 8, 2020. Roughly 42% of worldwide members and 30% of U.S. members have racially and ethnically assorted foundations. The preliminary is proceeding to select and is relied upon to proceed through the last examination when an aggregate of 164 affirmed COVID-19 cases have gathered. The investigation likewise will assess the potential for the antibody possibility to give insurance against COVID-19 in the individuals who have had earlier presentation to SARS-CoV-2, just as immunization avoidance against serious COVID-19 infection. Notwithstanding the essential adequacy endpoints assessing affirmed COVID-19 cases accumulating from seven days after the subsequent portion, the last investigation currently will incorporate, with the endorsement of the FDA, new auxiliary endpoints assessing viability dependent on cases building 14 days after the subsequent portion also. The organizations accept that the expansion of these optional endpoints will help adjust information over all COVID-19 antibody reads and consider cross-preliminary learnings and correlations between these novel immunization stages. Pfizer and BioNTech are proceeding to gather security information and presently gauge that a middle of two months of wellbeing information following the second (and last) portion of the antibody up-and-comer – the measure of security information indicated by the FDA in its direction for likely Emergency Use Authorization – will be accessible by the third seven day stretch of November. Moreover, members will keep on being checked for long haul assurance and wellbeing for an extra two years after their subsequent portion. Alongside the viability information created from the clinical preliminary, Pfizer and BioNTech are attempting to set up the important wellbeing and assembling information to submit to the FDA to exhibit the security and nature of the antibody item delivered. In view of gracefully projections, we hope to flexibly internationally up to 50 million antibody portions in 2020 and fabricate up to 1.3 billion dosages in 2021. Pfizer and BioNTech plan to submit information from the full Phase 3 preliminary for logical friend survey distribution.
