CAMB/MAT2203 in Patients With Mucocutaneous Candidiasis

Patients aged 18 to 75 years with mucocutaneous candidiasis (esophageal, oropharyngeal, or
vulvovaginal) who are refractory or intolerant to standard non-intravenous therapies will be
enrolled. Patients will initially be treated in a short-term dose titration period, where the
dose may be increased in patients that do not respond clinically. Patients who do not respond
clinically to the highest dose of drug will discontinue the protocol. Patients that respond
to treatment and tolerate the study medication will be eligible to enter a long-term
extension (up to 36-months).

Inclusion Criteria:

- Patients must have a clinical diagnosis of at least one of the following:

- Persistent OPC for greater than 2 weeks documented on at least one occasion by KOH or
fungal stain and confirmed by mycological culture to be azole resistant within the
previous 6 months and/or intolerance to standard non intravenous therapies.

- EC associated with clinical symptoms of retrosternal pain, odynophagia, and/or pain
with swallowing and documented by esophageal biopsy or visualization with culture
documenting azole resistance within the previous 6 months and/or intolerance to
standard non-intravenous therapies.

- Persistent VVC for greater than 2 weeks as documented by presence of vaginal symptoms
and a positive wet mount showing Candida structures and confirmed by a vaginal culture
positive for Candida with azole resistance within the previous 6 months and/or
intolerance to standard non intravenous therapies.

- Patient is expected to survive for > = 6 months.

- Willing to have samples stored for future research.

- Agree to use highly effective contraception.

- Contraception: Because the effects of CAMB on the developing human fetus are
unknown, sexually active patients of childbearing potential must agree to use
highly effective contraception as outlined below before study entry and for the
duration of study participation. Females of childbearing potential must have a
negative pregnancy test result before receiving CAMB. During the course of the
study, if a patient becomes pregnant or suspects they are pregnant, then they
should inform the study staff and their primary care physician immediately.
Acceptable forms of contraception are:

- Intrauterine device (IUD) or equivalent.

- Hormonal contraceptives (eg, consistent, timely and continuous use of
contraceptive pill, patch, ring, implant, or injection that has reached full
efficacy prior to dosing). If the patient uses contraceptive pill, patch, or
ring, then a barrier method (eg, male/female condom, cap, or diaphragm plus
spermicide) must also be used at the time of potentially reproductive sexual
activity.

- Be in a stable, long-term monogamous relationship, per PI assessment, with a
partner that does not pose any potential pregnancy risk, eg, has undergone a
vasectomy at least 6 months prior to first dose of study agent or is of the
same sex as the patient.

- Have had a hysterectomy and/or a bilateral tubal ligation or both ovaries
removed.

Exclusion Criteria:

- Allergy to any AMB product or any component of CAMB (eg, phosphatidylserine)

- Have evidence of systemic fungal infections requiring intravenous antifungal therapy

- Pregnant or nursing women, and women intending to become pregnant during the study
period

- Had a concomitant medical condition that could interfere with study drug evaluation or
that is a contraindication to the proposed investigational treatment based upon known
agent safety profile or toxicities.

- Had any of the following laboratory abnormalities at the screening visit:

- Alanine Transaminase (ALT), Aspartate Transaminase (AST) and Alkaline phosphatase
(ALP) > 2.5 times the upper limit of normal (ULN).

- Total bilirubin level > 2.5 times the ULN

- Serum creatinine level > 2 times the ULN

- Absolute neutrophil count less than 500 cells/microliter

- Potassium level less than or equal to 3.5 mmol/L

- Exposure to any investigational agent within 4 weeks prior to Day 0 (Baseline).

- Current or recent history (past 12 months) of drug or alcohol abuse.

- Use of intravenous AMB products within 1-week of start of study drug administration

- Use of non-intravenous AMB products (such as oral AMB swishes) within 72 hours prior
to start of study drug administration

- Subjects receiving potassium supplements.

- Any other condition the investigator believes would interfere with the patient s
ability to provide informed consent, comply with study instructions, or which might
confound the interpretation of the study results or put the subject at undue risk.
