These KBMA vaccines were then to be tested in mice to determine whether they were less virulent than live LVS and sent to UNM for evaluation of protective efficacy against a SCHU S4 challenge. The sensitivity of uvrB LVS to photochemical inactivation with S-59 psoralen and ultraviolet light (UVA) was evaluated. The S-59 psoralen concentration required to inactivate uvrB LVS was the same concentration at which wild-type LVS was inactivated. This result led Cerus to initiate experiments to determine whether this lack of increased sensitivity was general, or specific to photochemical inactivation with S-59 and UVA. The uvrB LVS was not more sensitive to other DNA damaging agents compared to wild-type LVS. These results suggested that there are redundant and unidentified DNA repair mechanisms in Francisella species that function to repair nucleotide crosslinks. This resistance to DNA crosslinking suggested that the inactivated uvrB LVS vaccine would provide no advantage over photochemically inactivated wild-type LVS vaccine, which had previously failed to protect mice against lethal a SCHU S4 challenge (see MS 46). These findings were consistent with results from NER mutants of Ft novicida (see MS 41 and MS 42), and led Cerus to reevaluate the KBMA tularemia vaccine strategy. Cerus proposed to terminate this milestone when only 5% complete, and instead focus efforts on developing liveattenuated and KBMA Listeria monocytogenes vaccines that express Ft antigens. UNM and NIAID supported the termination of Milestone 44. Cerus focused new efforts on developing liveattenuated and KBMA L. monocytogenes vaccines that expressed Ft antigens in order to induce and study the cellular immune response in new Milestones 55-59.

An SOP for photochemical inactivation will be delivered to UNM for review, comments and approval. The lack of increased sensitivity of ∆uvrB mutants of LVS and F. novicida to photochemical inactivation suggests that Ft subspecies may have a redundant or alternate DNA repair mechanism that prevents them from being amenable to formulation as KBMA vaccines. For this reason, Milestone 44 was terminated when only 5% complete. Though originally planned, MS 44 1) will not test the attenuation of the psoralen treated KBMA F. tularensis LVS uvrB compared to wild type LVS in mice 2) will not produce a larger-scale protocol for photochemical inactivation and 3) will not determine the virulence of the KBMA ∆uvrB LVS. NIAID and UNM approved a plan to change the focus from a KBMA ∆uvrB LVS vaccine to a Listeria monocytogenes-based vaccine under other milestones. 3 Methods, Critical Reagents and SOPs Handling of bacteria. Cultivation of Ft holarctica LVS strains was performed at 37oC using Cystine Heart Agar (Difco) supplemented with 10% bovine hemoglobin (Becton, Dickinson) as solid medium (CHAH) for colony enumeration following PRP01.002. For liquid cultivation of LVS strains, individual colonies or cell bank material were inoculated into Chamberlain’s defined medium (CDM) and incubated at 37oC with shaking at ~200 RPM. For preparation of CDM liquid media, 24.2 grams premixed formulation (Teknova cat# C0715) is added to water, the pH is adjusted to 6.26 and sterile filtered through 0.22 m filters. Photochemical inactivation. Inactivation was carried out by following Cerus_Ft_protocol_005. Briefly, 50mL of CDM were inoculated with 1mL of cell bank material and grown overnight at 37oC. 3.15 mL of CDM containing various concentrations of S-59 were then added to each well of two 6 well dishes in parallel (plate A and B). 0.35 mL of overnight culture was added to each well and incubated at 37oC. Plate A was used to monitor the replication of the bacteria. When the growth rate slowed to ½ the maximal rate (early stationary phase) in Plate A, plate B was illuminated with 6.5 J/cm2 of UVA light. To determine the degree of inactivation, bacteria from plate B were distributed on CHAH plates to determine if there were any remaining viable cfu using diluted and undiluted culture. Bacteria that had not been illuminated (from plate A) were used to determine the number of viable bacteria that had been inactivated by following QCP-01-003 protocol. Minimum inhibitory concentration (MIC) assay. To determine the sensitivity of the NER mutant LVS to alternative sources of DNA damage, 15 mL of CDM were inoculated with 1mL of cell bank material and grown overnight at 37oC. In the morning, cultures were diluted 1:100 in fresh CDM. Serial dilutions of DNA-damaging agents were made in 96 well plates and 50 µl/well were transferred to duplicate 96 well plates to which 100 µl/well of diluted overnight cultures of Page 3 of 14 Tularemia Vaccine Development Contract Contract No. HHSN266200500040-C and ADB Contract No. N01-AI-50040 Prime Contractor: University of New Mexico Milestone Completion Report: MS # 44 Institution: Cerus Corporation Author: Justin Skoble MS Start Date:6/18/07 MS End Date:6/15/08 Report Date: 5/11/09 Version: 2.0 Page 4 of 14 Reviewed by : Barbara Griffith 5/19/09, 5/27/09, 6/25/09, 8/7/09 Accepted Date:5/27/09 LVS or uvrB LVS were added.

Francisella tularensis (Ft) subspecies holarctica live vaccine strain (LVS) was produced by serial passage and is attenuated for unknown reasons. While it is used as a live attenuated vaccine to protect laboratory personnel, it’s pathway to FDA licensure is obstructed due to the uncharacterized nature of the attenuation. The aim of Milestone 44 was to produce and evaluate a killed but metabolically active (KBMA) vaccine using a photochemically inactivated nucleotide excision repair (NER)-deficient strain of LVS. KBMA vaccines are produced by a process of photochemical inactivation of organisms using a synthetic psoralen (S-59) and ultraviolet light (UVA). The ultraviolet light activates the S59 to crosslink nucleic acids and prevents the replication of the bacterial chromosome. Photochemical inactivation is a process used commercially by Cerus for pathogen Page 4 of 14 Tularemia Vaccine Development Contract Contract No. HHSN266200500040-C and ADB Contract No. N01-AI-50040 Prime Contractor: University of New Mexico Milestone Completion Report: MS # 44 Institution: Cerus Corporation Author: Justin Skoble MS Start Date:6/18/07 MS End Date:6/15/08 Report Date: 5/11/09 Version: 2.0 Page 5 of 14 Reviewed by : Barbara Griffith 5/19/09, 5/27/09, 6/25/09, 8/7/09 Accepted Date:5/27/09 inactivation in plasma and platelet products for transfusion. Nucleotide excision repair (NER) is the primary mechanism of repair of crosslinked DNA. This NER process is initiated by the exinuclease complex composed of the products of the uvrA, uvrB, and uvrC genes. While a broad range of wild-type pathogens can be killed by photochemical inactivation, bacteria that are engineered to be NER deficient generally are exquisitely sensitive to the process, and replication can theoretically be prevented with a single crosslink. Photochemical inactivation with randomly distributed infrequent crosslinks allows NERdeficient bacteria to maintain a high degree of metabolic activity while preventing replication, leading to a state we refer to as KBMA. This KBMA vaccine concept has been demonstrated with uvrAB mutants of Listeria monocytogenes, Bacillus anthracis, and Salmonella typhimurium. With all three species, the NER- mutant bacteria were significantly more sensitive to photochemical inactivation, maintained a higher degree of metabolic activity, and a broader expression profile when compared to wild type organisms. Because LVS is more difficult to genetically manipulate than Ft novicida and required development of novel tools by UTSA, initial proof of concept studies were done using Ft novicida NER mutants, with the intent of identifying a single mutant that could then be developed in LVS. In M S41the ∆uvrB mutant of Ft novicida was found to be equally sensitive to photochemical inactivation as a ∆uvrA strain or a double mutant strain ∆uvrA/∆uvrB. Thus the ∆uvrB LVS strain was selected for evaluation as a KBMA LVS vaccine candidate. Because engineering of this strain was expected to take a significant amount of time, initial conditions for cultivation and inactivation of wild-type LVS were established in MS 46 and these conditions were replicated for the ∆uvrB mutant in Milestone 44. Defining photochemical inactivation conditions for uvrB LVS. In MS 46 Cerus determined that chamberlains defined medium (CDM) was an excellent medium for cultivation of LVS, and was used as the medium in which photochemical inactivation would be performed. In MS 41 Cerus developed a small-scale photochemical inactivation process using 6 well dishes containing 3.5ml of culture in each well in order to evaluate the sensitivity of strains to photochemical inactivation (Cerus_Ft_protocol_005). To determine the sensitivity of ∆uvrB LVS to photochemical crosslinking, increasing concentrations of S59 were added to each well of 6 well dishes containing one bacterial strain. The dishes were illuminated with 6.5 J/cm2 of UVA light and ~1x109 bacteria were plated onto 5 CHAH plates and incubated for 2-3 days to allow for colonies to form. Cfu were enumerated and the data and are presented below (F-1). Complete inactivation was achieved at 5µM S-59. This is the exact same concentration of S-59 at which wild-type LVS was inactivated (MS 46). This finding is unusual for organisms that are NER-deficient (e.g. ∆uvrAB mutants of L. monocytogenes and B. anthracis), but is consistent with the observation that Ft novicida NER mutants were inactivated with similar concentrations of S-59 and were not more metabolically active than the wild-type strain (MS 41). Photochemical inactivation of LVS was investigated despite the lack of sensitivity of Ft novicida to confirm that the subspecies Page 5 of 14 Tularemia Vaccine Development Contract Contract No. HHSN266200500040-C and ADB Contract No. N01-AI-50040 Prime Contractor: University of New Mexico Milestone Completion Report: MS # 44 Institution: Cerus Corporation Author: Justin Skoble MS Start Date:6/18/07 MS End Date:6/15/08 Report Date: 5/11/09 Version: 2.0 Page 6 of 14 Reviewed by : Barbara Griffith 5/19/09, 5/27/09, 6/25/09, 8/7/09 Accepted Date:5/27/09 would behave in a similar manner. The lack of increased sensitivity of ∆uvrB mutants of LVS and F. novicida to photochemical inactivation suggests that Ft subspecies may have a redundant or alternate DNA repair mechanism that prevents them from being amenable to formulation as KBMA vaccines. For this reason, Milestone 44 was terminated when only 5% complete.

Dishes were then illuminated with 6.5 J/cm2 of UVA and plated on CHAH plates for cfu enumeration. Notebook 963, page 081. Additional investigations into sensitivity of uvrB LVS to DNA damaging agents: To determine whether the uvrB mutant’s lack of increased sensitivity to DNA crosslinking was specific to S-59 and UVA treatment or was more general, Cerus initiated experiments to compare the sensitivity to alternative DNA damaging agents of uvrB LVS with wild-type LVS. Minimum inhibitory concentration (MIC) assays were performed using the DNA damaging agents S-303 and cisplatin which had been shown in MS 41 to inhibit the growth of Ft novicida. Both uvrB LVS clones received from UTSA (clone 1-A and 1-B) were compared with DVC lot 16 LVS. As with S-59, the uvrB LVS mutants were not more sensitive to growth inhibition by S-303- or cisplatin-induced DNA damage (F-2, A and B, respectively). Surprisingly, growth of the wild-type LVS strain appeared to be inhibited to a greater extent at intermediate concentrations of both S-303 and cisplatin than either of the two uvrB clones. One possible explanation for this apparent paradoxical increase in resistance of the uvrB mutants to DNA damaging agents may be that the process of gene deletion required serial passages that may have selected for clones that replicate more rapidly than the minimally passaged DVC lot 16 LVS. If this were the case, then the bacteria might achieve a higher optical density at concentrations that do not completely inhibit growth (as seen below).

This suggested that the uvrB LVS mutant would not be any more effective as a KBMA vaccine candidate than photochemically treated LVS. Since photochemically inactivated LVS did not protect mice against a lethal challenge with the Ft tularensis SchuS4 strain in Milestone 46, it seemed unlikely that this strategy was going to produce an effective vaccine using uvrB LVS. These findings were also consistent with results from NER mutants of Ft novicida (see MS 41 and MS 42), and led Cerus to reevaluate the KBMA tularemia vaccine strategy. Cerus proposed to terminate this milestone when only 5% complete, and instead focus efforts on developing liveattenuated and KBMA Listeria monocytogenes vaccines that express Ft antigens. UNM and NIAID supported the termination of Milestone 44. Cerus focused new efforts on developing live-attenuated and KBMA L. monocytogenes vaccines that expressed Ft antigens in order to induce a cellular immune response in new Milestones 55-59. 4.3 Quality Control Each experiment was documented in a laboratory notebook that was read, understood and countersigned by an individual who did not participate in the experiment. Deliverables Completed The deliverables for Milestone 44 were to be 1) a protocol for treating F. tularensis LVS ∆uvrA or ∆uvrB to produce optimally killed but metabolically active bacteria and 2) provide a report documenting their virulence compared to F. tularensis LVS challenge. A protocol for small scale inactivation of LVS ∆uvrB using 5µM S-59 and 6.5J/cm2 UVA is provided in Cerus_Ft_protocol_005. The milestone was terminated prematurely at approximately 5% completion because of the lack of sensitivity of ∆uvrB LVS to photochemical inactivation, and hence an inability to be formulated as an effective KBMA vaccine. Since there was an approved plan to change the focus from a KBMA ∆uvrB LVS vaccine to a Listeria monocytogenes-based vaccine, a larger-scale protocol for photochemical inactivation was not produced, nor was the virulence of the KBMA ∆uvrB LVS determined.
