A Phase III Study of AL3818 (Anlotinib) Hydrochloride Monotherapy in Subjects With Metastatic or Advanced Alveolar Soft Part Sarcoma, Leiomyosarcoma and Synovial Sarcoma

This study evaluates the safety and efficacy of AL3818 (anlotinib) hydrochloride in the
treatment of metastatic or advanced alveolar soft part sarcoma (ASPS), leiomyosarcoma (LMS),
and synovial sarcoma (SS). All participants with ASPS will receive open-label AL3818. In
participants with LMS or SS, AL3818 will be compared to IV dacarbazine. Two-thirds of the
participants will receive AL3818, one-third of the participants will receive IV dacarbazine.

APROMISS is a phase 3 study evaluating the safety and efficacy of AL3818 (anlotinib)
hydrochloride in the treatment of metastatic or advanced alveolar soft part sarcoma (ASPS),
leiomyosarcoma (LMS), and synovial sarcoma (SS). Population pharmacokinetics and exploratory
exposure-response analyses will also be conducted in subjects receiving AL3818.

Indication A: 56 subjects with metastatic or advanced ASPS not amenable to surgical resection
will receive open-label AL3818 at a dose of 12 mg once daily in 21-day cycles (14 days on
treatment, 7 days off treatment) until disease progression (defined by RECIST version 1.1) ot
unacceptable toxicity. The primary endpoint is objective response rate (ORR), secondary
endpoint is duration of response (DOR).

Indication B: 68 subjects with metastatic or advanced LMS who have failed at least one prior
line of approved therapy will be enrolled and randomized in a 2:1 ratio to receive either
AL3818 (12 mg once daily in 21-day cycles) or IV dacarbazine until disease progression
(defined by RECIST version 1.1) or unacceptable toxicity. Subjects randomized to dacarbazine
will have the option to crossover and receive AL3818 at the time of documented disease
progression. The primary endpoint is progression free survival (PFS), the secondary endpoint
is objective response rate (ORR).

Indication C: 95 subjects with with metastatic or advanced SS who have failed at least one
prior line of approved therapy, including first-line anthracycline-containing chemotherapy,
will be enrolled and randomized in a 2:1 ratio to receive either AL3818 (12 mg once daily in
21-day cycles) or IV dacarbazine until disease progression (defined by RECIST version 1.1) or
unacceptable toxicity. Subjects randomized to dacarbazine will have the option to crossover
and receive AL3818 at the time of documented disease progression. The primary endpoint is
progression free survival (PFS), the secondary endpoint is objective response rate (ORR).

not been free from menses for > 2 years. - Males must agree to use adequate
contraception since signing of the informed consent form until at least 3 months after
the last study drug administration. Adequate contraception is defined in the study as
any medically recommended method (or combination of methods) at the discretion of the
investigator.
