Plaintiff ______ (“Plaintiff”), by and through his attorneys, alleges the following upon

information and belief, except as to those allegations concerning Plaintiff, which are alleged

upon personal knowledge. Plaintiff’s information and belief is based upon, among other things,

his counsel’s investigation, which includes without limitation: (a) review and analysis of

regulatory filings made by VITAL THERAPIES CORPORATION (“Vital Therapies” or the

“Company”), with the United States Securities and Exchange Commission (“SEC”); (b) review

and analysis of press releases and media reports issued by and disseminated by Vital Therapies;

and (c) review of other publicly available information concerning Vital Therapies.

NATURE OF THE ACTION AND OVERVIEW

1. This is a class action on behalf of those who purchased or otherwise acquired

Vital Therapies’ securities between September 8, 2014 and August 21, 2015, inclusive (the

“Class Period”), seeking to pursue remedies under the Securities Exchange Act of 1934 (the

“Exchange Act”).

2. Vital Therapies, a biotherapeutic company, focuses on developing a cell-based

therapy for the treatment of acute liver failure in the United States. Its ELAD system is an

extracorporeal bio-artificial liver therapy that is in Phase III clinical trials to allow the patient’s

own liver to regenerate to a healthy state, or to stabilize the patient until transplant. The

Company was formerly known as Vitagen Acquisition Corp. and changed its name to Vital

Therapies, Inc. in June 2003.

3. On July 14, 2015, an analyst report published in Seeking Alpha alleged that the

Company misled investors regarding the ELAD systems patients’ overall survival rate, as Vital

Therapies included survival data from a patient who received a liver transplant, while no

equivalent patient in the control group had received a transplant. This fact was not disclosed in

any of the company's prior disclosures.

4. On this news, the Company’s shares fell $3.61 per share, or 14%, to close at

$23.10 on July 15, 2015, on unusually heavy trading volume.

5. On August 21, 2015, the Company announced topline results from its VTI-208

study, and reported that the study, “failed to achieve primary or secondary endpoints of

improvement in overall survival.”

6. On this news, the Company’s shares fell $13.55 per share, or over 76%, during

intra-day trading on August 24, 2015.

7. Throughout the Class Period, Defendants made false and/or misleading statements

regarding the future prospects of Vital Therapies’ ELAD system for the treatment of liver

disease. Specifically, Defendants made false and/or misleading statements and/or failed to

disclose: (1) that the ELAD system is using an immortal line of human cancer liver cells to filter

the blood of acute liver failure patients; (2) that inaccurate data was released regarding ELAD

patients’ overall survival rates; (3) that ELAD failed to demonstrate superiority across any

parameters when compared to a standard non-biological liver dialysis systems; and (4) that, as a

result of the foregoing, the Company’s statements were materially false and misleading at all

relevant times.

8. As a result of Defendants’ wrongful acts and omissions, and the precipitous

decline in the market value of the Company’s securities, Plaintiff and other Class members have

suffered significant losses and damages.

The results highlight the unmet need for AAH patients since there wasno statistically significant impact on patient survival at 90 days or one year byeither drug, although there was a short term benefit on survival at 28 days in thesubjects receiving steroids.

Third Quarter 2014 Financial Results

Cash Position

Cash and cash equivalents at September 30, 2014, totaled $79.1 million comparedto $38.2 million at December 31, 2013. Based on its current business plan, theCompany believes its existing cash and cash equivalents as of September 30,2014, along with the net proceeds after underwriting commissions and discountsof $33.4 million from its recent follow-on offering, will be sufficient to fundoperations into the fourth quarter of 2016.

Results of Operations

Three Months Ended September 30, 2014

The Company reported a net loss, and a net loss attributable to commonstockholders, for the quarter ended September 30, 2014 of $12.8 million. Thiscompares to a net loss of $7.0 million and a net loss attributable to commonstockholders of $9.0 million for the quarter ended September 30, 2013. Thisresulted in a net loss attributable to common stockholders of $0.59 per share forthe three months ended September 30, 2014, as compared to a net loss of $16.31per share for the corresponding period in 2013, on both a basic and fully dilutedbasis. These per share figures are based on weighted-average common sharesoutstanding of 21,759,061 shares and 553,790 shares, respectively, with the largeincrease in common shares outstanding resulting from the Company's initialpublic offering (IPO) in the second quarter of this year and the conversion ofpreferred stock to common stock in conjunction with the IPO.

Total operating expenses for the three months ended September 30, 2014were $12.8 million as compared to $9.2 million for the comparable period of2013. Research and development expenses increased to $10.2 million during thethree months ended September 30, 2014 as compared to $6.2 million in the threemonths ended September 30, 2013. This was primarily associated with anincrease in Phase 3 clinical trial activities. General and administrative expenseswere $2.6 million for the three months ended September 30, 2014, down from$3.0 million for the comparable period of 2013, primarily due to lower utilizationof outside services.

The net loss for the three months ended September 30, 2013 was net of otherincome of $2.2 million, reflecting the revaluation of future purchase rightsliabilities. These future purchase rights terminated in conjunction with the IPO.

21. On November 13, 2014, Vital Therapies also filed its Quarterly Report with the

SEC on Form 10-Q for the 2014 fiscal third quarter. The Company’s Form 10-Q was signed by

Defendant Swanson, and reaffirmed the Company’s statements previously announced that day.

22. On March 19, 2015, the Company issued a press release entitled, “Vital

Therapies Announces Fourth Quarter and Full Year 2014 Financial Results and Provides a

Corporate Update.” Therein, the Company, in relevant part, stated:

Vital Therapies, Inc. (Nasdaq:VTL), a biotherapeutic company developingELAD®, a cell-based therapy targeting the treatment of acute liver failure, todayannounced results for the fourth quarter and fiscal year ended December 31, 2014and provided a corporate update.

"With completion of enrollment in VTI-208 and topline results expected later thisyear, we are now focused on enrolling our second phase 3 trial, VTI-210, andpreparing for a potential Biologics License Application submission targeted forthe first half of 2016 should VTI-208 yield positive results," said Terry Winters,Ph.D., Chief Executive Officer and Co-Chairman of Vital Therapies.

Key Developments

The total number of subjects enrolled was 203 with the lastsubject enrolled on January 31, 2015, reflecting the further enrollment of subjectswho were already in the screening process when enrollment reached 200. TheCompany now expects to report topline results from this trial in the third quarterof 2015 due to a decision to wait until database lock before beginning toplineanalysis of the data. The Company still anticipates filing a Biologics LicenseApplication (BLA) in the first half of 2016 if the results of VTI-208 are positive.

Commenced enrollment in the Company's second phase 3 trial, VTI-210, arandomized, controlled, open-label study evaluating the ELAD System in severeacute alcoholic hepatitis patients who have failed standard therapy.

Cash and cashequivalents at December 31, 2014, totaled $102.2 million compared to $38.2million at December 31, 2013. Based on the current business plan, the Companybelieves it has enough cash to fund the Company into the third quarter of 2016,which is a quarter earlier than previously expected due to higher projected costsprincipally associated with preparations to file a BLA in the event of positiveVTI-208 results.

Thisevent-driven trial targets enrollment of a minimum of 150 subjects with a primaryendpoint of overall survival up to at least study day 91. The Company continuesto expect to release topline results from VTI-210 in early 2017.

Enrolled the sixth subject as of May 11, 2015 in VTI-212, a single-arm phase 2trial, evaluating the ELAD System in 40 subjects with either fulminant hepaticfailure or surgery-induced liver failure. The Company continues to expect toplineresults from VTI-212 in 2016.

Presented two posters at the annual meeting of the European Association for theStudy of the Liver (EASL) in Vienna last month. The first poster describes thedemographics and baseline laboratory values of subjects enrolled in the VTI-208trial showing that the key parameters of average age and MELD (Model of End-stage Liver Disease) score at baseline were both within the trial's target rangesestablished from VTI-206, the Company's phase 2b AILD trial. The second posterdescribes research into ELAD's possible mechanisms of action. The postercharacterizes the expression levels of liver-specific cytochrome P450 isoenzymesand oxygenases in ELAD C3A cells during cartridge production and after use inclinical treatment. Both posters are available on the Company's web site.

Cash and cash equivalents at March 31, 2015, totaled $88.3 million compared to$102.2 million at December 31, 2014. Based on the current business plan, theCompany believes it has enough cash to fund the Company into the third quarterof 2016, although the Company's projected cash runway will be highly dependenton the topline results of the VTI-208 clinical trial. The Company is filing auniversal shelf registration statement on Form S-3 with the United StatesSecurities and Exchange Commission (SEC) today. However, the Company willnot access the public markets prior to the release of VTI-208 topline results in thethird quarter of 2015.

Results of Operations

Three Months Ended March 31, 2015

The Company reported both a net loss and net loss attributable to commonstockholders of $14.8 million for the quarter ended March 31, 2015, whichcompared with a net loss of $10.7 million, and a net loss attributable to commonstockholders of $13.8 million for the same prior year period. This resulted in a netloss attributable to common stockholders of $0.62 per share for the three monthsended March 31, 2015, as compared to a net loss of $24.49 per share for thecorresponding period in 2014, on both a basic and fully diluted basis. These pershare figures are based on weighted-average common shares outstanding of23,972,599 shares and 564,186 shares, respectively, with the large increase incommon shares outstanding in 2014 resulting from the Company's initial publicoffering (IPO) in the second quarter of 2014, the conversion of preferred stock tocommon stock in conjunction with the IPO, and the Company's follow-onoffering in the fourth quarter of 2014.

Total operating expenses for the three months ended March 31, 2015 were $14.8million as compared to $11.9 million for the comparable period of 2014. Researchand development expenses increased to $11.8 million during the three monthsended March 31, 2015 as compared to $9.2 million in the three months endedMarch 31, 2014. This was primarily associated with an increase in clinical trial-related activities. General and administrative expenses were $3.1 million for thethree months ended March 31, 2015, up from $2.7 million for the comparableperiod of 2014.

25. On May 12, 2015, Vital Therapies also filed its Quarterly Report with the SEC on

Form 10-Q for the 2015 fiscal first quarter. The Company’s Form 10-Q was signed by

Defendant Swanson, and reaffirmed the Company’s statements previously announced that day.

26. The statements contained in ¶¶17-23 were materially false and/or misleading

when made because defendants failed to disclose or indicate the following: (1) that the ELAD

system is using an immortal line of human cancer liver cells to filter the blood of acute liver

rates; (3) that ELAD failed to demonstrate superiority across any parameters when compared to a

standard non-biological liver dialysis system; and (4) that, as a result of the foregoing, the

Company’s statements were materially false and misleading at all relevant times.

Disclosures at the End of the Class Period

27. On July 16, 2015, an article was published on Seeking Alpha entitled, “Vital

Therapies’ ELAD VTI-208 Study – Chronicle of a Failure Foretold.” Therein, the article, in

relevant part, stated:

Summary

Vital’s ELAD system is using an immortal line of human cancer liver cellsto filter the blood of acute liver failure patients. After over 20 years of R&D and several bankruptcies, the ELADtechnology has yet to succeed in a single pivotal trial with statistical significance. ELAD failed to demonstrate superiority across any parameters whencompared to the MARS system, an approved non-biological liver dialysis system. Based on past clinical data and patient baseline characteristics, we assumethat Vital’s ongoing VTI-208 phase 3 study will fail to demonstrate statisticalsignificance in 91-day overall survival.

In 2003 Vital Therapies (NASDAQ:VTL) emerged from the ashes of twobankrupt companies who had been trying to develop the Extracorporeal LiverAssist Device (ELAD) biological liver dialysis technology for over 10 years.Hepatix Inc, founded in 1991, was the initial developer of ELAD. The companydeclared bankruptcy by 1996 and was re-registered under the trade name VitaGen- which in turn went bankrupt in 2003. The ELAD technology was acquired byVital Therapies in the bankruptcy proceedings of VitaGen and, over 20 yearslater, the technology has yet to succeed in a single pivotal trial with statisticalsignificance.

The ELAD system is using an immortal line of liver cells to filter the blood ofacute liver failure (ALF) patients. Although this solution sounds highly lucrative,ELAD appears to be nothing more than living proof that the efficacy of such asystem does not currently extend beyond sheer theoretical hype. ThroughoutELAD's laborious 20-year quest in search of patients it can help, both the weight

of the cells in a single ELAD cartridge and the number of hepatic indications atwhich the device has tried its luck have steadily accumulated. Unfortunately,neither did the trick as the technology has yet to find its match in terms of hepaticindication and, due to the fact that liver disease comprises one of the mostheterogeneous patient populations in medicine, this may take a very long time.

According to Vital's latest annual report, the U.S. FDA is also skeptical of ELAD:"the FDA has noted its view that preliminary clinical evidence…does not indicatethat the ELAD System may demonstrate a substantial improvement over thecurrent standard of care". Added to that is the fact that the incidence of mostadverse events was found to be nearly three-fold in ELAD-treated patients vscontrol (and vs patients treated with other dialysis systems in similar settings),and the fact that ELAD runs a potential risk of leaking cancerous liver cells intothe very patients it treats.

Performance in previous trials is a good indication of the drug/therapy'sperformance in future trials, and in the case of VTL, the future appears to be atotal failure. After dozens of studies in humans and petri dishes ELAD has givenabsolutely no indication that it can demonstrate statistical significance in theongoing Phase 3 trials.

An even more telling sign of failure is the fact that ELAD failed to demonstratesuperiority across any parameters when compared to a standard non-biologicalliver dialysis system, perhaps superseding such a device only in its cost, beingapproximately 10 times more expensive. When the results of ELAD's latest trialwere directly compared with the Phase 3 results of the non-biological MARSdialysis system (with the obvious limitations of a cross trial comparison), ELADwas shown to have poorer efficacy even despite the fact that MARS failed itsPhase 3 study. For this reason it is extremely unlikely that the VTI-208 trial, theresults of which are being awaited in Q3 '15, will meet its 91-day overall survivalprimary endpoint.

***

Conclusion

Clinical trials so far have shown that the benefits of the ELAD system beingdeveloped by Vital Therapies are purely hypothetical, as this live human cell linedialysis therapy repeatedly failed to show a survival benefit and has proven to beinferior to a standard non-biological system across most endpoint parameters.

Moreover, the benefits which the device has demonstrated in previous trials wereexaggerated and are much smaller than the figures commonly presented to VTL'sinvestors. In addition, the adverse events associated with the ELAD therapy aredangerously numerous and serious. This report has presented proof that the Phase3 VTI-208 trial is extremely likely to fail.

Upon the likely failure of the VTI-208 study, the future of ELAD in liver failuretreatment should be finally (and a bit too late) doomed. Accordingly, Vital's stockprice should drop considerably since further studying ELAD in other ALF sub-populations will bare an even greater failure risk.

28. On this news, the Company’s shares fell $3.61 per share, or 14%, to close at

$23.10 on July 15, 2015, on unusually heavy trading volume.

29. On August 21, 2015, the Company issued a press release announcing topline

results from its VTI-208 study, and reported that the study, “failed to achieve primary or

secondary endpoints of improvement in overall survival.” The press release further disclosed

that:

VTI-208, the Company's phase 3 randomized, controlled, open-label trial,evaluating the ELAD System in subjects with alcohol-induced liverdecompensation (AILD) failed to meet the primary endpoint of overall survivalthrough at least 91 days assessed using the Kaplan Meier statistical method. Of203 total subjects enrolled in VTI-208, 96 were randomized to the treated groupand 107 were randomized to the control group. A hazard ratio of 1.027 (slightlyfavoring the control group) with a log rank p-value of 0.90 (not statisticallysignificant, N.S.) indicated that there was no difference between treated andcontrol subjects in the primary endpoint.

The Company will be analyzing the data from the VTI-208 clinical trial duringthe next several weeks, including data from the pre-specified subset analyses. TheCompany will stop the VTI-210 and VTI-212 clinical trials, and also plans tomeet with the FDA as soon as possible to discuss restructuring its clinicaldevelopment program, including a potential new trial to confirm the informationsuggested by the subset analyses. The Company will then give more details on apossible path forward with ELAD.

While the overall results are disappointing, the Company is encouraged that alarge pre-specified subset of 120 subjects with a MELD score of less than 28 hada hazard ratio of 0.575 and a log-rank p-value of 0.077 (N.S.) in favor of theELAD group, suggesting that future clinical studies should focus on this cohortwith MELD scores less than 28. Separately, a pre-specified subset of 101subjects under age 46.9 years (the study median age) had a hazard ratio of 0.634with a log-rank p-value of 0.167 (N.S.) in favor of the ELAD treated subjects,suggesting that future study designs may incorporate stratification by age. Indeedthese effects appear to be additive and a subset of 59 subjects with MELD lessthan 28 and age less than 46.9 years had a hazard ratio of 0.375 in favor of theELAD group (p=0.085 (N.S.)). Finally, pre-specified analyses suggest that

subjects with impaired kidney function and severe coagulopathy may have worseoutcomes and therefore future clinical trials will exclude these subjects.

With $62.0 million in current cash, the Company believes it could complete a newtrial without raising additional capital, although that will depend on discussionswith regulatory authorities and the exact design of any new trial.

30. On this news, the Company’s shares fell $13.55 per share, or over 76%, during

intra-day trading on August 24, 2015.

CLASS ACTION ALLEGATIONS

31. Plaintiff brings this action as a class action pursuant to Federal Rule of Civil

Procedure 23(a) and (b)(3) on behalf of a class, consisting of all those who purchased or

otherwise acquired Vital Therapies’ securities between September 8, 2014 and August 21, 2015,

inclusive and who were damaged thereby (the “Class”). Excluded from the Class are

Defendants, the officers and directors of the Company, at all relevant times, members of their

immediate families and their legal representatives, heirs, successors or assigns and any entity in

which Defendants have or had a controlling interest.

32. The members of the Class are so numerous that joinder of all members is

impracticable. Throughout the Class Period, Vital Therapies’ securities were actively traded on

the Nasdaq Stock Market (“NASDAQ”). While the exact number of Class members is unknown

to Plaintiff at this time and can only be ascertained through appropriate discovery, Plaintiff

believes that there are hundreds or thousands of members in the proposed Class. Millions of

Vital Therapies shares were traded publicly during the Class Period on the NASDAQ. As of

February 27, 2015, Vital Therapies had 23,993,389 shares of common stock outstanding. Record

owners and other members of the Class may be identified from records maintained by Vital

Therapies or its transfer agent and may be notified of the pendency of this action by mail, using

the form of notice similar to that customarily used in securities class actions.

33. Plaintiff’s claims are typical of the claims of the members of the Class as all

members of the Class are similarly affected by Defendants’ wrongful conduct in violation of

federal law that is complained of herein.

34. Plaintiff will fairly and adequately protect the interests of the members of the

Class and has retained counsel competent and experienced in class and securities litigation.

35. Common questions of law and fact exist as to all members of the Class and

predominate over any questions solely affecting individual members of the Class. Among the

questions of law and fact common to the Class are:

(a) whether the federal securities laws were violated by Defendants’ acts as

alleged herein;

(b) whether statements made by Defendants to the investing public during the

Class Period omitted and/or misrepresented material facts about the business, operations, and

prospects of Vital Therapies; and

(c) to what extent the members of the Class have sustained damages and the

proper measure of damages.

35. A class action is superior to all other available methods for the fair and efficient

adjudication of this controversy since joinder of all members is impracticable. Furthermore, as

the damages suffered by individual Class members may be relatively small, the expense and

burden of individual litigation makes it impossible for members of the Class to individually

redress the wrongs done to them. There will be no difficulty in the management of this action as

a class action.

UNDISCLOSED ADVERSE FACTS

36. The market for Vital Therapies’ securities was open, well-developed and efficient

at all relevant times. As a result of these materially false and/or misleading statements, and/or

failures to disclose, Vital Therapies’ securities traded at artificially inflated prices during the

Class Period. Plaintiff and other members of the Class purchased or otherwise acquired Vital

Therapies’ securities relying upon the integrity of the market price of the Company’s securities

and market information relating to Vital Therapies, and have been damaged thereby.

37. During the Class Period, Defendants materially misled the investing public,

thereby inflating the price of Vital Therapies’ securities, by publicly issuing false and/or

misleading statements and/or omitting to disclose material facts necessary to make Defendants’

statements, as set forth herein, not false and/or misleading. Said statements and omissions were

materially false and/or misleading in that they failed to disclose material adverse information

and/or misrepresented the truth about Vital Therapies’ business, operations, and prospects as

alleged herein.

38. At all relevant times, the material misrepresentations and omissions particularized

in this Complaint directly or proximately caused or were a substantial contributing cause of the

damages sustained by Plaintiff and other members of the Class. As described herein, during the

Class Period, Defendants made or caused to be made a series of materially false and/or

misleading statements about Vital Therapies’ financial well-being and prospects. These material

misstatements and/or omissions had the cause and effect of creating in the market an

unrealistically positive assessment of the Company and its financial well-being and prospects,

causing the Company’s securities to be overvalued and artificially inflated at all relevant times.

Defendants’ materially false and/or misleading statements during the Class Period resulted in

LOSS CAUSATION

39. Defendants’ wrongful conduct, as alleged herein, directly and proximately caused

the economic loss suffered by Plaintiff and the Class.

40. During the Class Period, Plaintiff and the Class purchased Vital Therapies’

securities at artificially inflated prices and were damaged thereby. The price of the Company’s

securities significantly declined when the misrepresentations made to the market, and/or the

information alleged herein to have been concealed from the market, and/or the effects thereof,

were revealed, causing investors’ losses.

SCIENTER ALLEGATIONS

41. As alleged herein, Defendants acted with scienter in that Defendants knew that

the public documents and statements issued or disseminated in the name of the Company were

materially false and/or misleading; knew that such statements or documents would be issued or

disseminated to the investing public; and knowingly and substantially participated or acquiesced

in the issuance or dissemination of such statements or documents as primary violations of the

federal securities laws. As set forth elsewhere herein in detail, Defendants, by virtue of their

receipt of information reflecting the true facts regarding Vital Therapies, his/her control over,

and/or receipt and/or modification of Vital Therapies’ allegedly materially misleading

misstatements and/or their associations with the Company which made them privy to

confidential proprietary information concerning Vital Therapies, participated in the fraudulent

scheme alleged herein.

APPLICABILITY OF PRESUMPTION OF RELIANCE(FRAUD-ON-THE-MARKET DOCTRINE)

42. The market for Vital Therapies’ securities was open, well-developed and efficient

at all relevant times. As a result of the materially false and/or misleading statements and/or

failures to disclose, Vital Therapies’ securities traded at artificially inflated prices during the

Class Period. On April 24, 2015, the Company’s stock closed at a Class Period high of $29.37

per share. Plaintiff and other members of the Class purchased or otherwise acquired the

Company’s securities relying upon the integrity of the market price of Vital Therapies’ securities

and market information relating to Vital Therapies, and have been damaged thereby.

43. During the Class Period, the artificial inflation of Vital Therapies’ stock was

caused by the material misrepresentations and/or omissions particularized in this Complaint

causing the damages sustained by Plaintiff and other members of the Class. As described herein,

during the Class Period, Defendants made or caused to be made a series of materially false

and/or misleading statements about Vital Therapies’ business, prospects, and operations. These

material misstatements and/or omissions created an unrealistically positive assessment of Vital

Therapies and its business, operations, and prospects, thus causing the price of the Company’s

securities to be artificially inflated at all relevant times, and when disclosed, negatively affected

the value of the Company stock. Defendants’ materially false and/or misleading statements

during the Class Period resulted in Plaintiff and other members of the Class purchasing the

Company’s securities at such artificially inflated prices, and each of them has been damaged as a

result.

44. At all relevant times, the market for Vital Therapies’ securities was an efficient

market for the following reasons, among others:

(a) Vital Therapies stock met the requirements for listing, and was listed and

actively traded on the NASDAQ, a highly efficient and automated market;

(b) as a regulated issuer, Vital Therapies filed periodic public reports with the

SEC and/or the NASDAQ;

(c) Vital Therapies regularly communicated with public investors via

established market communication mechanisms, including through regular dissemination of

press releases on the national circuits of major newswire services and through other wide-

ranging public disclosures, such as communications with the financial press and other similar

reporting services; and/or

(d) Vital Therapies was followed by securities analysts employed by

brokerage firms who wrote reports about the Company, and these reports were distributed to the

sales force and certain customers of their respective brokerage firms. Each of these reports was

publicly available and entered the public marketplace.

45. As a result of the foregoing, the market for Vital Therapies’ securities promptly

digested current information regarding Vital Therapies from all publicly available sources and

reflected such information in Vital Therapies’ stock price. Under these circumstances, all

purchasers of Vital Therapies’ securities during the Class Period suffered similar injury through

their purchase of Vital Therapies’ securities at artificially inflated prices and a presumption of

reliance applies.

NO SAFE HARBOR

46. The statutory safe harbor provided for forward-looking statements under certain

circumstances does not apply to any of the allegedly false statements pleaded in this Complaint.

The statements alleged to be false and misleading herein all relate to then-existing facts and

conditions. In addition, to the extent certain of the statements alleged to be false may be

characterized as forward looking, they were not identified as “forward-looking statements” when

made and there were no meaningful cautionary statements identifying important factors that

could cause actual results to differ materially from those in the purportedly forward-looking

statements. In the alternative, to the extent that the statutory safe harbor is determined to apply to

any forward-looking statements pleaded herein, Defendants are liable for those false forward-

looking statements because at the time each of those forward-looking statements was made, the

speaker had actual knowledge that the forward-looking statement was materially false or

misleading, and/or the forward-looking statement was authorized or approved by an executive

officer of Vital Therapies who knew that the statement was false when made.

FIRST CLAIMViolation of Section 10(b) of

The Exchange Act and Rule 10b-5Promulgated Thereunder Against All Defendants

47. Plaintiff repeats and realleges each and every allegation contained above as if

fully set forth herein.

48. During the Class Period, Defendants carried out a plan, scheme and course of

conduct which was intended to and, throughout the Class Period, did: (i) deceive the investing

public, including Plaintiff and other Class members, as alleged herein; and (ii) cause Plaintiff and

other members of the Class to purchase Vital Therapies’ securities at artificially inflated prices.

In furtherance of this unlawful scheme, plan and course of conduct, defendants, and each of

them, took the actions set forth herein.

49. Defendants (i) employed devices, schemes, and artifices to defraud; (ii) made

untrue statements of material fact and/or omitted to state material facts necessary to make the

statements not misleading; and (iii) engaged in acts, practices, and a course of business which

operated as a fraud and deceit upon the purchasers of the Company’s securities in an effort to

maintain artificially high market prices for Vital Therapies’ securities in violation of Section

10(b) of the Exchange Act and Rule 10b-5. All Defendants are sued either as primary

participants in the wrongful and illegal conduct charged herein or as controlling persons as

alleged below.

50. Defendants, individually and in concert, directly and indirectly, by the use, means

or instrumentalities of interstate commerce and/or of the mails, engaged and participated in a

continuous course of conduct to conceal adverse material information about Vital Therapies’

financial well-being and prospects, as specified herein.

51. These defendants employed devices, schemes and artifices to defraud, while in

possession of material adverse non-public information and engaged in acts, practices, and a

course of conduct as alleged herein in an effort to assure investors of Vital Therapies’ value and

performance and continued substantial growth, which included the making of, or the

participation in the making of, untrue statements of material facts and/or omitting to state

material facts necessary in order to make the statements made about Vital Therapies and its

business operations and future prospects in light of the circumstances under which they were

made, not misleading, as set forth more particularly herein, and engaged in transactions,

practices and a course of business which operated as a fraud and deceit upon the purchasers of

the Company’s securities during the Class Period.

52. Each of the Individual Defendants’ primary liability, and controlling person

liability, arises from the following facts: (i) the Individual Defendants were high-level executives

and/or directors at the Company during the Class Period and members of the Company’s

management team or had control thereof; (ii) each of these defendants, by virtue of their

responsibilities and activities as a senior officer and/or director of the Company, was privy to and

participated in the creation, development and reporting of the Company’s internal budgets, plans,

familiarity with the other defendants and was advised of, and had access to, other members of the

Company’s management team, internal reports and other data and information about the

Company’s finances, operations, and sales at all relevant times; and (iv) each of these defendants

was aware of the Company’s dissemination of information to the investing public which they

knew and/or recklessly disregarded was materially false and misleading.

53. The defendants had actual knowledge of the misrepresentations and/or omissions

of material facts set forth herein, or acted with reckless disregard for the truth in that they failed

to ascertain and to disclose such facts, even though such facts were available to them. Such

defendants’ material misrepresentations and/or omissions were done knowingly or recklessly and

for the purpose and effect of concealing Vital Therapies’ financial well-being and prospects from

the investing public and supporting the artificially inflated price of its securities. As

demonstrated by Defendants’ overstatements and/or misstatements of the Company’s business,

operations, financial well-being, and prospects throughout the Class Period, Defendants, if they

did not have actual knowledge of the misrepresentations and/or omissions alleged, were reckless

in failing to obtain such knowledge by deliberately refraining from taking those steps necessary

to discover whether those statements were false or misleading.

54. As a result of the dissemination of the materially false and/or misleading

information and/or failure to disclose material facts, as set forth above, the market price of Vital

Therapies’ securities was artificially inflated during the Class Period. In ignorance of the fact

that market prices of the Company’s securities were artificially inflated, and relying directly or

indirectly on the false and misleading statements made by Defendants, or upon the integrity of

the market in which the securities trades, and/or in the absence of material adverse information

that was known to or recklessly disregarded by Defendants, but not disclosed in public

statements by Defendants during the Class Period, Plaintiff and the other members of the Class

acquired Vital Therapies’ securities during the Class Period at artificially high prices and were

damaged thereby.

55. At the time of said misrepresentations and/or omissions, Plaintiff and other

members of the Class were ignorant of their falsity, and believed them to be true. Had Plaintiff

and the other members of the Class and the marketplace known the truth regarding the problems

that Vital Therapies was experiencing, which were not disclosed by Defendants, Plaintiff and

other members of the Class would not have purchased or otherwise acquired their Vital

Therapies securities, or, if they had acquired such securities during the Class Period, they would

not have done so at the artificially inflated prices which they paid.

56. By virtue of the foregoing, Defendants have violated Section 10(b) of the

Exchange Act and Rule 10b-5 promulgated thereunder.

57. As a direct and proximate result of Defendants’ wrongful conduct, Plaintiff and

the other members of the Class suffered damages in connection with their respective purchases

and sales of the Company’s securities during the Class Period.

SECOND CLAIMViolation of Section 20(a) of

The Exchange Act Against the Individual Defendants

58. Plaintiff repeats and realleges each and every allegation contained above as if

fully set forth herein.

59. The Individual Defendants acted as controlling persons of Vital Therapies within

the meaning of Section 20(a) of the Exchange Act as alleged herein. By virtue of their high-level

positions, and their ownership and contractual rights, participation in and/or awareness of the

Company’s operations and/or intimate knowledge of the false financial statements filed by the

Company with the SEC and disseminated to the investing public, the Individual Defendants had

the power to influence and control and did influence and control, directly or indirectly, the

decision-making of the Company, including the content and dissemination of the various

statements which Plaintiff contends are false and misleading. The Individual Defendants were

provided with or had unlimited access to copies of the Company’s reports, press releases, public

filings and other statements alleged by Plaintiff to be misleading prior to and/or shortly after

these statements were issued and had the ability to prevent the issuance of the statements or

cause the statements to be corrected.

60. In particular, each of these Defendants had direct and supervisory involvement in

the day-to-day operations of the Company and, therefore, is presumed to have had the power to

control or influence the particular transactions giving rise to the securities violations as alleged

herein, and exercised the same.

61. As set forth above, Vital Therapies and the Individual Defendants each violated

Section 10(b) and Rule 10b-5 by their acts and/or omissions as alleged in this Complaint. By

virtue of their positions as controlling persons, the Individual Defendants are liable pursuant to

Section 20(a) of the Exchange Act. As a direct and proximate result of Defendants’ wrongful

conduct, Plaintiff and other members of the Class suffered damages in connection with their

purchases of the Company’s securities during the Class Period.
