[0001] COMPOSITIONS FOR PROMOTING GROWTH OF LACTOBACILLUS CRISPATUS

[0002] Technical field

[0003] The present invention relates to methods and compositions for promoting and increasing growth of Lactobacillus crispatus.

[0004] Background

[0005] Lactobacillus crispatus and Gardnerella vaginalis are among the most prominent vaginal bacteria associated with health and disease of the vagina. While Lactobacillus species are associated with a healthy microflora due to their production of hydrogen peroxide and lactic acid which lowers the vaginal pH and discouraging the growth of anaerobic bacteria, G. vaginalis is one of the species associated with bacterial vaginosis (BV) and considered a key component of the anaerobic diversity responsible for symptoms found in BV patients. G. vaginalis are known for their production of a biofilm, clusters of bacteria attached to the vaginal epithelia. Bacteria in a biofilm are protected from the immune system and antibiotics. A BV infection is proceeded by what is referred to as “a shift in vaginal flora”, whereby the Lactobacillus species are lost, and this shift paves way for the anaerobic pathogenic bacteria, e.g. G. vaginalis (Kalia et al. 2020, Falconi-McCahill 2019).

[0006] A disrupted reproductive tract microbiome has been associated with unfavourable outcomes of pregnancy and reproductive complications. Ascending bacterial infection from the vagina through the cervix into the uterine cavity is considered to be a major cause of preterm birth (Goldenberg et al, Lancet, 2008, 37, 9606, 75-849; MacIntyre et al, Sci Rep, 2015, 5, 8988). Many of these cases also exhibit chorioamnionitis, constituting a major threat also to the mother, before the pathogen is identified and effective antibiotic treatment is commenced. The link between vaginal microbial community structure and ascending infection is also highlighted in late miscarriage, in recurrent spontaneous abortion, in chronic cervicitis / endometritis leading to implantation problems and female infertility. A healthy vaginal microbiome during pregnancy should be dominated by only one or a few Lactobacillus species (MacIntyre et al, Sci Rep, 2015, 5, 8988, Romero et al, Microbiome, 2014, 2, 1 ,4), something that is an acknowledged problem with a great medical need among pregnant women. Summary

[0007] It has previously been shown that glucono-delta-lactone (GDL) inhibits bacterial growth, for example the growth of pathogenic bacteria of the vaginal microbiome such as Gardnerella vaginalis. In particular, it has previously been shown that a lower minimal inhibitory concentration (MIC) of GDL is required to inhibit the growth of G. vaginalis as compared to the MIC required to inhibit the growth of L. crispatus (Example 13, Table 9 of WO 2019 / 0668862) and thus that GDL is more efficient against G. vaginalis than against L. crispatus. Thus, administration of GDL at a suitable concentration may enable simultaneous decrease of levels of G. vaginalis and maintenance of levels of L. crispatus.

[0008] The inventors of the present invention have however surprisingly found that administration of GDL in fact increases the growth of Lactobacillus crispatus. In other words, GDL enables and promotes growth of L. crispatus rather than inhibits growth of L. crispatus at relevant concentrations. Hence, the present invention provides methods and compositions for increasing (i.e. promoting) growth of L. crispatus comprising administering said composition to a subject in need thereof.

[0009] In one aspect, the present invention relates to a method of increasing growth and / or reproduction of Lactobacillus crispatus in a subject, the method comprising administering to the subject a composition comprising glucono-delta-lactone (GDL), or a pharmaceutically acceptable salt thereof.

[0010] In one aspect, the present invention relates to use of a composition comprising glucono-delta-lactone (GDL), or a pharmaceutically acceptable salt thereof, for increasing growth and / or reproduction of Lactobacillus crispatus in a subject.

[0011] In one aspect, the present invention relates to a composition comprising glucono-delta- lactone (GDL), or a pharmaceutically acceptable salt thereof, for use for increasing growth and / or reproduction of Lactobacillus crispatus in a subject.

[0013] In one aspect, the present invention relates to an in vitro method of growing Lactobacillus crispatus, the method comprising incubating Lactobacillus crispatus in a growth medium comprising or consisting of a composition comprising glucono-delta- lactone (GDL),

Classification of the vaginal samples bacterial composition, as measured with qPCR, Day 0 (before treatment) and Day 7 (after treatment) into different community state types (CST) based on the Vaginal Community State Type Nearest Centroid Classifier (VALENCIA, France et al. 2020). Most of the samples falls in category IV-B at day 0 (before treatment), which is the community state type (CST) associated with a low relative abundance of any Lactobacillus species and high to moderate abundance of G. vaginalis and A. vaginae. For patients treated with Formulation A (n=103), there is a shift in CST category at day 7 (after treatment) as compared to Day 0 (before treatment) to a lower CST category, mainly to CST III, which denotes a vaginal microbiome community with increased levels of Lactobacilli and reduction of vaginal dysbiosis. For placebo (n=25), this shift is not seen. Detailed description

[0021] Definitions

[0022] The terms “dysbiosis” or dysbiotic” as used herein refers to a disrupted microbiome resulting in an imbalance in the microbiota and a shift in the distribution of microbial species of the microbiome as compared to a non-disrupted, balanced and healthy microbiome. Preferably, the term as used herein refers to a dysbiosis in the urogenital, such as in the vaginal, microbiome, wherein the normally dominating species, such as Lactobacillus in the vaginal microbiome, have become underrepresented and the normally non-dominating species, such as Gardnerella vaginalis, Escherichia coli, Mobiluncus spp., Staphylococcus aureus etc. in the vaginal microbiome, have increased or taken over. Dysbiosis of the vaginal microbiome can result in various conditions, for example bacterial vaginosis. Whether or not a vaginal microbiome is dysbiotic can be determined by methods known in the art, for example as described by France et al., 2020.

[0023] The term “increasing growth and / or reproduction” as used herein refers to the process of increasing, promoting or enabling growth of a microorganism. In other words, the term refers to the process of increasing, promoting or enabling the division of microbial cells, such as L. crispatus cells, so that the total number (i.e. the level or amount) of microbial cells increases over time. The increase in growth or reproduction of microbial cells can be determined using various methods that are well known in the art. For example, cell growth or reproduction can be measured by measuring the optical density (OD) (i.e. the absorbance at 600 nm) of a cell culture over time. If the OD remains constant or decreases over time, no growth or reproduction has occurred. If the OD increases over time, growth or reproduction has occurred. The growth or reproduction can also be measured by quantitative polymerase chain reaction (qPCR) (also over time, e.g. at two time point), which can provide the absolute or relative amount of a bacterial species, such as L. crispatus, in a microbiome, such as in the vaginal microbiome. If the absolute or relative amount of a bacterial species increased over time, growth or reproduction of the bacteria has occurred.

[0024] The growth and / or reproduction of a specific microorganism may for example have increased after administration of a composition as described herein, wherein said increase is relative to the growth and / or reproduction of the same microorganism grown under the same conditions but in the absence of said composition.

[0232] The effects on abundance of Lactobacilli in general and Lactobacillus crispatus in particular in the vaginal swab samples were assessed by qPCR analysis of the vaginal swab samples from patients treated with the Formulation A tablets as compared to patients treated with the placebo tablet, at day 0 and day 7 respectively.

[0233] The abundance of total Lactobacilli increased significantly between day 0 (before treatment) and day 7 (after treatment) for almost all patients treated with tablets of Formulation A (Fig. 3 and Fig. 4).

[0234] In particular, the abundance of L. crispatus increased significantly between day 0 (before treatment) and day 7 (after treatment) for patients treated with Formulation A tablet (Fig. 5). Simultaneously, a significant decrease could be seen in the abundance of G. vaginalis (Fig. 5).

[0235] Further, there is a significant reduction of vaginal dysbiosis (lower CST category) at day 7 (after treatment) as compared to Day 0 (before treatment) in patients treated with Formulation A. For placebo, this shift is not seen (Fig. 6).
