简要总结
Part C: to investigate the efficacy of oral pritelivir 100 mg once a day in immunocompromised subjects with acyclovir (ACV)-resistant (ACV-R) mucocutaneous herpes simplex virus (HSV) infections for a treatment period of 28 days as a maximum in comparison to "Investigator's Choice treatment" for a max treatment duration of 28 days
Part D (complete): investigate the efficacy of oral pritelivir 100 mg once a day in immunocompromised subjects with ACV-R and foscarnetR/intolerant mucocutaneous HSV infections for a treatment period of 28 days as a maximum
Part E: to investigate the safety and tolerability of oral pritelivir 100 mg once a day in immunocompromised subjects with ACV-S mucocutaneous HSV infections for a treatment period of 28 days as a maximum.
Part F (complete): investigate the safety and tolerability of oral pritelivir 100 mg once a day in immunocompromised subjects with ACV-R and foscarnet-R/intolerant mucocutaneous HSV infections for a treatment period of 28 days as a maximum after completion of enrollment in Part D.

入选标准
- •Immunocompromised (due to conditions including but not limited to HIV infection, hematopoietic cell or solid organ transplantation, and chronic use of immunosuppressive treatment) men and women of any ethnic group aged ≥16 years. In Canada, Germany, Belgium: Immunocompromised (due to conditions including but not limited to HIV infection, hematopoietic cell or solid organ transplantation, and chronic use of immunosuppressive treatment) men and women of any ethnic group aged ≥18 years.
- •ACV-R mucocutaneous HSV infection based on clinical failure or positive genotypic/phenotypic ACV resistance testing for current lesion. Clinical failure is defined as no improvement after oral or iv doses for at least 7 days at doses equivalent to or greater than the local agency approved high doses of acyclovir, valacyclovir or Famciclovir.
- •Lesions accessible for visual inspection to allow assessment of lesion healing including visualization by endoscopy.
- •Willing to remain abstinent (refrain from heterosexual intercourse) or use highly effective contraceptive methods (defined below): The reliability of sexual abstinence should be evaluated in relation to the duration of the clinical study and the preferred and usual lifestyle of the participant. Periodic abstinence (eg, calendar, ovulation, or post-ovulation methods) and withdrawal are not acceptable methods of contraception. Male subjects must remain abstinent,be surgically sterile (eg, documented vasectomy) or must agree to use an adequate method of contraception during sexual intercourse with women of childbearing potential for at least 6 months after the final dose of trial medication. Male subjects must refrain from sperm donation during the same period. Female subjects of non-childbearing potential must be either surgically sterile (documented hysterectomy, bilateral tubal ligation, salpingectomy, and/or bilateral oophorectomy or postmenopausal (defined as amenorrhea for at least 12 months without an alternative medical cause) at start of treatment). Female subjects of childbearing potential must remain abstinent, have a sole vasectomized partner, or must agree to use an adequate method of contraception. Female subjects must refrain from donating eggs during the same period. An adequate method of contraception is defined as a highly effective method of contraception (failure rate of <1% per year) plus use of a condom during participation in this trial and for at least 6,5 complete months after the final dose of foscarnet and 1 complete month after the last dose of pritelivir. A highly effective method of contraception is defined as: o copper intrauterine device, o the levonorgestrel-releasing intrauterine system, o the progestogen implant, o combined (estrogen and progestogen containing) hormonal contraception (oral, intravaginal, transdermal) associated with inhibition of ovulation, o progestogen-only hormonal contraception (oral, injectable, implantable) associated with inhibition of ovulation.
- •Subject, and/or their legally authorized representative, must be willing and able (in the opinion of the Investigator) to understand the Informed Consent Form.
- •Negative serum β-HCG (beta-human chorionic gonadotropin) test for women of childbearing potential at Screening and a negative urine pregnancy test at Day
- •Subject must give written informed consent. For subjects, who are unable to provide informed consent for whatever reason, written consent must be obtained from the legal representative.
- •Parts D (complete) and F (complete): Inclusion criteria in Part D are identical to those in Part C, except for inclusion criteria 2 which is replaced by:
- •ACV-R and foscarnet-R mucocutaneous HSV infection based on clinical failure or positive genotypic/phenotypic resistance testing for current lesion or documented intolerance to foscarnet requiring cessation of foscarnet treatment or precluding foscarnet treatment. Clinical failure of ACV treatment is defined as no improvement after oral or iv doses for at least 7 days at doses equivalent to or greater than the local agency approved high doses of acyclovir, valacyclovir, or famciclovir. Clinical failure of foscarnet treatment is defined as no improvement after at least 7 days offoscarnet iv therapy. For subjects coming from Part C due to clinical failure of foscarnet, clinical failure is defined as discontinuation and/or replacement of foscarnet after at least 7 days of treatment due to worsening of lesion(s) and/or appearance of new lesion(s). Manifestations of foscarnet intolerance may include, impairment of renal function, seizures, genital irritation and/or ulcerations, extremity paresthesia, nausea, granulocytopenia, anemia, leukopenia, thrombopenia, hypokalemia, hypocalcemia, hypomagnesemia, diabetes insipidus, injection site reactions, psychiatric disorders, including but not limitedto anxiety and aggression. Subjects entering Part D or Part F (both complete) after cessation of foscarnet treatment in Part C will require a washout period of at least 3 days prior to starting pritelivir. New subjects may be enrolled into Part F (complete) only after closure of enrollment in Part D (complete).
- •Part E (not being conducted in Germany) Inclusion criteria in Part E are identical to those in Part C, except for inclusion criterion 2 which is replaced by:
- •Recurrent mucocutaneous HSV infection considered ACV-S.
