As a result
The virulence of passage enhancing recombination listerisa monocytogenes in mjme in mouse
By three different constructs for determining influence of the passage to recombinant listeria bacterium vaccine carrier.These constructs
In two carrying passerby's antigens genomes be inserted into:First includes HIV gag genes (Lm-Gag), and second includes
HPV E7 genes (Lm-E7).The plasmid that third (Lm-LLO-E7) includes has the passerby merged with the LLO of clipped form anti-
The gene of the fusion and coding prfA of former (HPV E7), prfA are the positive regulatory factors for controlling Listeria virulence factor.
The plasmid, so that in host living, selects pressure to be beneficial to plasmid conservation for supplementing prfA negative mutants, because
There is no plasmid bacterium then non-toxic.All 3 constructs have bred many generations extensively in bacterium in vitro.
Sub-culturing bacteria results in the increase of bacterial virulence, and as measured by the existence bacterial population in spleen, each is all
It is preceding 2 generation.For Lm-Gag and Lm-LLO-E7, virulence increases with each passage, until 2nd generation (Fig. 7 A).Containing plasmid
Construct Lm-LLO-E7 shows most significant virulence and increases.Before passage, the primary immune dosage of Lm-LLO-E7 must increase
To 107A bacterium, and spleen must be harvested on day 2 to recycle bacterium (and for the 10 of Lm-Gag5A bacterium it is initial
Dosage then harvests on day 3).After initial passage, the standard dose of Lm-LLO-E7 is sufficient to make and can harvest on day 3.It is right
In Lm-E7, the bacterium through not passing on, virulence increases by 1.5 orders of magnitude (Fig. 7 B).Therefore, Li Si is increased by mouse passage
The virulence of special bacteria vaccine bacterial strain.
Passage increases listerisa monocytogenes in mjme and induces CD8+The ability of T cell
Next, using HIV-Gag peptides AMQMLKETI (SEQ ID No:And LLO 91-99 (GYKDGNEYI 25);SEQ
ID No:26), by carrying out intracellular cytokine dyeing with MHC I class specific immunity dominant epitopes, and passage pair is determined
Antigentic specificity CD8+The effect of T cell.By 103The passage bacterium (Lm-Gag) of a CFU is injected into mouse and produces largely
HIV-Gag specific Cs D8+T cell, and the Lm-Gag that do not pass on of same dose does not induce detectable Gag specific Cs D8+T is thin
Born of the same parents.The dosage for not passing on bacterium is even increased by 100 times and does not also compensate their relative virus force;In fact, even higher
Detectable Gag specific Cs D8 is not caused under dosage yet+T cell.Same dose using passage bacterium is thin by Gag specificity Ts
Born of the same parents' induction increases 50% (Fig. 8).Using LLO specific Cs D8+T cell observed identical antigentic specificity CD8+T cell
Induction pattern, caused by showing these results not and being the property by passerby's antigen, because they are anti-with endogenous Listeria
It is observed when former LLO.Therefore, the immunogenicity of Listeria vaccine strains is increased by mouse passage.

It is described.
The solution development of plasmid is extracted from Listeria
By 1mL listerisa monocytogenes in mjme Lm-LLO-E7 research work cell bank virus inoculations to contain 34 μ g/
In the 27mL BH1 culture mediums of mL CAP, and grown 24 hours under 37 DEG C and 200rpm.
Make the culture samples precipitation (15000rpm continues 5 minutes) of seven 2.5mL, and by sediment at 37 DEG C with 50
μ l lysozyme solns incubate the different durations from 0-60 minutes.
Lysozyme soln:
- 29 μ l1M dipotassium hydrogen phosphates
- 21 μ 11M potassium dihydrogen phosphates
40% sucrose of -500 μ l (passes through 0.45 μm of filter aseptic filtration)
- 450 μ l water
- 60 μ l lysozymes (50mg/mL)
After being incubated with lysozyme, suspension is centrifuged as previously described, and abandon supernatant.Then receive each precipitation logical
Cross the QIAprep Spin Miniprep of modified version(Qiagen, Germantown, Maryland) scheme carries out
Plasmid extraction.Scheme is amended as follows:
1. the volume of buffer solution PI, P2 and N3 improve three times, so that increased biomass can be cracked completely.
2. the lysozyme of 2mg/mL is added in the cell being resuspended, P2 is then added.Then by cracked solution at 37 DEG C
It incubates 15 minutes, then is neutralized.
3. Plasmid DNA is resuspended in 30 μ L rather than to improve concentration in 50 μ L.
In other experiments, cell is incubated 15 minutes in P1 buffer solutions+lysozyme, then (is split with P2 at room temperature
Solve buffer solution) and P3 (neutralization buffer) incubations.
The Plasmid DNA of the separation derived from each squamous subculture of equal volume is run on 0.8% Ago-Gel, uses bromine
Change the sign of the dyeing of second ingot and observation structure or segregational instability.
The result shows that from the plasmid extraction efficiency of listerisa monocytogenes in mjme Lm-LLO-E7 as lysozyme incubates

Sequencing:
The sequencing of plasmid has been carried out using dideoxy sequencing method.By plasmid pGG55 D133V and pGG55WT with different ratios
Rate (1: 1,1: 10,1;100,1: 1,000 and 1: 10,000) mixing.The total amount of plasmid in mixture is kept constant into (500 μ g),
And the plasmid comprising wild-type sequence is carried out 10 times about D133V plasmids and is serially diluted to determine the sensitivity of method.
As a result
Example 6:Sequencing is not the sensitive method for the reply for detecting D133V mutation.
In order to estimate the sensitivity being sequenced in detecting wild type prfA sequences, by pGG55 D133V and WT plasmids with not
Same ratio is mixed and is sequenced.As a result it is shown in FIG. 12, and disclose sequencing there is height in distinguishing prfA D133V mutation
Specific (Figure 12).On the other hand, sensitivity is relatively low, and the wild type prfA pGG55 with detectable peak in the sequence
The greatest dilution of plasmid is 1/10 (Figure 12).Although in short, sequencing have very high specificity, this method it is sensitive
It spends relatively low, and is unsuitable for screening depositing for rare events (such as prfA D133V be mutated revertant) in Lm-LLO-E7 samples
Property.
Example 7:Exploitation high degree of specificity and sensitive PCR method come detect D133V mutation reply.
The muting sensitivity of rare events is detected in view of with sequencing, it is necessary to which developing has the more sensitive of similar specificity
Method detects the reply of wild type D133V mutation.In order to realize the target, we devise a kind of method of based on PCR, should
In 10,000,000 D133V mutant nucleotide sequences copies of method specific amplification wild-type sequence and enough Sensitive Detections at least
1 wild type prfA copy.We devise 3 primers for this method:ADV451, ADV452 and ADV453 (table 1).
ADV451 and ADV452 is forward primer, and difference is the last one nucleotide of 3 ' positions to distinguish the position of prfA genes
Set A → T (D133V) mutation at 398.ADV453 primers be positioned at ADV451 and ADV452 primers annealing site downstream about
Reverse primer (Figure 13) at 300bp.Expection PCR bands obtained by primer ADV451 or ADV452 and ADV453 are 326bp.
Under stringent condition, ADV451 primers should not expand pGG55 D133V plasmids, and ADV452 will be wild type prfA sequence-specifics
's.
Example 8:The specificity of PCR method.
There is very high specificity using the reaction of primer ADV451, and expanded the D133V prfA sequences of mutation
(swimming lane 1 to 3), but wild-type sequence (swimming lane 4 to 6) is not expanded.However, when the template DNA for using 5ng rather than using 1ng
When, very weak band (Figure 14) can be detected in swimming lane 4.
As shown in Figure 15, wild type prfA sequences (swimming lane 4,5 and 6) have only been expanded using the reaction of ADV452 primers,
Band (swimming lane 1,2 and 3) is not detected when the pGG55 for carrying D133V prfA mutation is used as template, or even works as and is reacting
It is also such (Figure 16) when middle use 5ng plasmids.In short, being had using the PCR reactions of primer ADV451 and ADV452 very high
Specificity, and can distinguish at the positions 398 of prfA genes in pGG55 plasmids(D133V) it is mutated.Base
In these as a result, we select the amount of 1ng as the standard volume that will use template DNA in the reaction.
Example 9:The sensitivity of PCR method.
The sensitivity of reaction is tested using the template DNA of 1ng.For carrying the plasmid of wild type prfA sequences, will also
The amount of DNA of reduction (corresponds to from 10-1To 10-710 times dilution) include in the reaction to estimate sensitivity.In these reactions
In, it only used primer ADV452 and ADV453.With 30 cycle (10 cycle annealing temperatures be 53 DEG C, another 20
The annealing temperature of cycle is 50 DEG C) PCR reactions in, the sensitivity of method is 1/100,000 (data are not shown).In Fig. 5
Shown, PCR cycle number is increased to 37 and improves the visual sensitivity of method to 10 by the detection for D133V revertants-6, without
Apparent damage specificity.When 1ng plasmids are used as initial amount of DNA, 10-6Visible apparent band under dilution, this corresponds to
The detection level that 1 wild-type sequence copies in 1000000 D133V mutant.After longer exposure in swimming lane 1 and 9 only
Very weak band can be observed, again ensured that method is reliably specific.On the other hand, when being started with 5ng DNA,
10-7Band is can easily detect under dilution, to improve the sensitivity of PCR.However, using pGG55 D133V plasmids
Also the band that can detect similar strength, to show the specific limit (Figure 17) of method.It is seen by pGG55 D133V plasmids
The band observed may be the non-specific amplification due to being mutated to D133V with primer ADV452, by increased recurring number,
The mutation can obviously accumulate.These the result shows that unobvious damage specificity in the case of this method sensitivity limit position
Between 1: 1,000,000 and 1: 10,000,000.
Example 10:Express the recombinant listeria bacterium of the fusion protein (LM-LLO-E7) of LLO and E7
The attenuation degree of the bacterial strain secretes fusion egg than about 4-5 order of magnitude of wild-type parent bacterial strain 10403S high
White tLLO-E7.The immunotherapy is based on skeleton XFL7, passes through the irreversible missing in virulence gene activating transcription factor prfA
And it is derived from 10403S.PrfA regulates and controls several virulence gene such as Listeriolysin O (LLO), ActA, PlcA (phosphatidases
A), the transcription of PlcB (phospholipase B) etc., these genes are the growth of internal intracellular and existence of listerisa monocytogenes in mjme
Required.Plasmid pGG55 is kept by the selection of " chloramphenicol " by Lm-LLO-E7 in vitro.However, for Lm-LLO-E7
For the internal holding of plasmid, the copy of the prfA (D133V) of mutation is carried, it is had proven to and combines and activate poison in DNA
Activity in terms of the transcription of power gene is not so good as wild type PrfA.We have observed that causing with the complementation of the prfA of mutation
Compared with wild-type strain 10403S about 40 times are reduced from the amount of the Lm-LLO-E7 LLO secreted.This is implied:Bacterial strain Lm-LLO-
E7 may show the expression of virulence gene actA, inlA, inlB, inlC, plcB for being regulated and controled by PrfA for reducing etc..
In Lm-LLO-E7, the table by the PrfA different virulence genes regulated and controled may be led to the prfA of the mutation complementations copied
Up to reduction, the about 4-5 order of magnitude is attenuated so as to cause overall.

ADXS11-001 well-tolerateds, 1-2 grades of fatigues, to shiver and generate heat be the AE most often reported.
Only 5 patient experiences with treatment-related 3 grades or 4 grades of AE (n=4,3 grades;N=1,4 grades).
Among 26 patients receiving treatment, 18 complete and (are received in 3 months according to the entire treatment of scheme
3 doses of axalimogene filolisbac), middle position overall survival phase is more than 1 year (12.1 months), 12 months overall survivals
Reach 55.6% (Figure 26).Degree (1-3 items treat line) regardless of the past therapy, realizes 12 months life cycles
(Figure 27), and axalimogene filolisbac well-tolerateds, 1 grade or 2 grades of fatigues, shiver and fever be it is most common with
Treatment-related adverse events.
CONSORT figures (Figure 29) depict selected and then patient receiving treatment sum in stage 1 and 2 and are connect
The ADXS11-001 dosage received is distributed.In 26 patients receiving treatment in stage 1, the middle position agent number received is 3 (models
Enclose 1-3), 69% (n=18) receives most 3 doses.In 24 patients receiving treatment in stage 2, the middle position agent that is received
Number is 2.5 (range 1-6), and 50% (n=12) receives >=3 doses.At clinical test pause (then continuing) again, 10
Patient actively receives ADXS11-001.Wherein, 4 (40%) patients receive >=3 doses, and 6 (60%) patients receive < 3
Agent.Upper table 7 gives the Baseline demographic's statistics and Clinical symptoms of the patient in selected stage 1 and stage 2.
Safety/tolerance
All patients (26 treated in the stage 1 of research;100%) there is at least 1 adverse events (AE).At 24
(92%) in patient, these AE are related to treatment (TRAE):19 (73%) only have 1-2 grades of TRAE, and 4 (15%) has 3 grades
TRAE, 1 (4%) patient has may relevant 4 grades of TRAE.The TRAE of most common > 30% be fatigue, shiver, generate heat,
Nausea and headache (table 10)
Safety results in the patient in selected stage 2 are similar to 1 play-by-play of stage.
Curative effect
For the patient (n=26) treated in the stage 1 of research:
- 12 months survival rates are 38.5% (n=10/26).
The patient (n=10/26) to live at 12 months receives 1 treatment line (3/8 patient), 2 treatment lines (6/14
Patient) or 3 the past whole-body dose treatments for treating line (1/4 patient), show, regardless of the degree of the past treatment, to realize
12 months survival rates.
Middle position OS is 7.7 months (95% confidence intervals [CI]:3.9-12.4), middle position progression free survival phase (PFS) is
3.1 months (95%CI:2.8-3.7;Figure 23 and Figure 24).
20/26 through the patient for the treatment of in report researcher assessment be found that best tumor response
- seven patient's (27%) stable diseases (SD), 10 patients's (38%) have progressive disease (PD).
According to the decision of researcher, remaining 6 patient is unable to evaluation response
The subsequent exploration that 18/26 patient (69%) to receiving all 3 doses of ADXS11-001 according to scheme carries out
Analysis shows that middle 1 year (12.1 [95%CI of position OS >:6.8- is not up to (NR)] a month), 12 months survival rates are 55.6% (figure
26)。
12 months survival rates of GOG/NRG-0265 are advantageously compared with the history GOG clinical tests series in PRmCC
Compared with3-15,18(Figure 30).
For the patient (n=24) treated in the stage 2 of research:
Due to 8.7 months limited median follow-up time time, 12 months survival rates of Primary Endpoint can not calculate.
- 6 months survival rates are 42% (10/24), and middle position OS is 4.8 months (95%CI:3.6-NR) (Figure 31 A)
Although 10/24 (42%) patient stops using ADXS11-001 and gets nowhere or extremely since clinical test suspends
It dies, but middle position PFS is 2.6 months (95%CI:2.0-3.2) (Figure 31 B), it is similar to being observed in the stage 1.
In 50% patient (12/24) for receiving 3 doses or more agent ADXS11-001, middle position OS is NR (95%CI:
3.5-NR), the median follow-up time time is 9.2 months, and 6 months survival rates are 67% (Figure 31 B).
20/24 through the patient for the treatment of in report researcher assessment be found that best tumor response.
- 1 (4%) patient experience complete reaction (CR), 8 (33%) experienced SD, and 11 (46%) has PD.
The clinical medical history and image for representing lasting CR are shown in Figure 32 and Figure 33.
