12-7-15/GEN: “Boosting Upstream & Downstream Output - Sartorius Stedim Biotech Forum Focuses On Next Level Bioprocess Operations”
By: K. John Morrow, PhD (CEO, Newport Biotech)
GEN = Genetic Engineering & Biotechnology News
At the recent Sartorius Stedim Biotech (SSB) Upstream & Downstream Technology Forum in Foster City, CA, (Oct6-7 2015 http://www.sartorius.com/en/upstream-downstream-forum ) speakers dealt with both sides of these technological challenges...
. . .SCALE UP & SCALE DOWN
With tangential flow filtration of protein solutions, researchers are able to concentrate and buffer exchange biotherapeutics to their proper dose and excipients, according to David Briggs, PhD, a research scientist in Mfg. Sciences & Technology at Avid Bioservices. “However, we recognize that at higher protein concentrations this may present a problem, and of course the future of the industry will focus on highly concentrated protein solutions,” he pointed out.
Dr. Briggs discussed his experiences in fine-tuning TFF (Tangential-Flow Filtration), which is also known as cross-flow filtration. The technology is based on running the field stream parallel to the filter device. Small molecules are eliminated, and the larger ones are concentrated in the retentate. While TFF can be employed anywhere in the protein purification process, in general it is only used in the final formulation step.
Dr. Briggs uses diafiltration (DF) in the purification process, by which new buffer is constantly introduced into the flow. With the dilution of the solutes the unwanted molecular species and residual starting buffer components are gradually removed. “During DF, keeping the retentate volume constant is necessary for efficiency and reproducibility,” he told the forum attendees.
A major feature of TFF is that it can be upscaled & downscaled to meet the demands of different protocols without adversely affecting the parameters of the process. The data establish that at large and small scale, flux rates were similar during concentration and that step yields and recovery rates during the entire TFF operation were similar. Finally, at both the manufacturing scale and at lab bench scale, conductivity decreases as a function of diavolumes were similar. . .

• Total Revs since May’06: ($138.6mm/Avid + $24.1mm/Govt + $2.4mm/Lic.) = $165.2mm
• Deferred-Revs at 7-31-15, going fwd into FY’16/Q2 (q/e 10-31-15), total $8.3mm, UP from the $6.6mm of Deferred-Revs at 4-30-15 that drove into FY’16/Q1.
• Avid’s Gross-Profit over last 3 qtrs: $12.5mm on revs of $24.4mm (GP% = 49%)
• Recall, Avid Rev$ from Gov’t DTRA Contract work (6/30/08 – 4/15/11, totaling $24.15mm), went into GOVT-REVS, not AVID-REVS, in the Financials.

9-10-15/OutsourcingPharma: “Avid Revs Likely to Grow Substantially”
9-10-15: “Peregrine Up on CMO Q1 Sales & Backlog, as New Plant Set to Go Online”
By Dan Stanton, Outsourcing-Pharma

Manufacturing backlog at Avid Bioservices has reached $42mm as the firm books up space at a new facility currently undergoing its first internal pilot run. For Q1/FY2016, Peregrine Pharmaceuticals reported record revenue from its contact mfg. business Avid Bioservices of $9.4mm, up 71% year-on-year. But revenues are likely to grow substantially, the firm said, as there is a $42mm committed backlog from existing customers which will be carried-out in part once a new mammalian cell culture mfg. facility in Tustin, CA comes online.
“The new manufacturing suite is fully built and the first internal pilot run is currently underway to verify all systems and equipment are properly functioning,” Peregrine CFO Paul Lytle said during an investor call yesterday. ”Our strategic investment in the Avid Bioservices business is already starting to pay dividends. Our clients are reserving mfg. slots in the new facility which has increased our revenue backlog to approximately $42mm.”
A large proportion of the firm’s revenues come from its major client, Halozyme Therapeutics, servicing monoclonal antibody development projects with Roche & Baxter. While the company hopes the new facility will attract new customers, it is the current customer base showing the most interest.
“In the new facility, a lot of the interest comes from the existing client base, even as much as we've had new potential customers coming through,” said CEO Steven King. “It's exciting, it's a real nice showpiece and it's really showing in the interest that it's generated from again the existing client base.”
The site, first announced last year, more than doubles Avid’s mfg. capacity, though some of the space has been reserved to service its parent company’s lead product bavituximab, a chimeric mAb in Phase III trials for non-squamous NSCLC. END
