The goal of this clinical trial is to evaluate the efficacy and safety of ASCA101 for the treatment of Cachexia in solid tumor patients. The main questions it aims to answer are:
Can the efficacy of ASCA101 in improving cachexia be evaluated based on changes in body weight measured by InBody after 12 weeks (3 cycles) of weekly administration, compared to baseline, for each dose group?

The goal of this clinical trial is to evaluate the efficacy and safety of ASCA101 for the treatment of Cachexia in solid tumor patients. The main questions it aims to answer are:
Can the efficacy of ASCA101 in improving cachexia be evaluated based on changes in body weight measured by InBody after 12 weeks (3 cycles) of weekly administration, compared to baseline, for each dose group?
Do participants experience adverse events during administration of ASCA101 and/or within 4 weeks after the end of administration?
This clinical trial comprises two parts. \[Study 1. Active-Controlled, Open-Label Study\] Participants who provide written informed consent will undergo screening procedures. Those who meet all inclusion criteria and none of the exclusion criteria will be eligible for enrollment and will be randomized to receive either ASCA101 (at one of two dose levels: 24.32 or 32.43 mg/kg) or an active control. Participants will receive the investigational product over 3 cycles (12 weeks). Each cycle consists of 28 days. Subjects in the ASCA101 group will receive the investigational drug twice weekly for a total of 8 doses per cycle. Participants in the active control group (megace F suspension) will receive the drug orally once daily.
\[Study 2. Placebo-Controlled, Double-Blind Study\] Participants who provide written informed consent will undergo screening procedures. Those who meet all inclusion criteria and none of the exclusion criteria will be eligible for enrollment and will be randomized to receive either ASCA101 (at one of two dose levels: 24.32 or 32.43 mg/kg) or placebo. Participants will receive the investigational product over 3 cycles (12 weeks). Each cycle consists of 28 days. Subjects in the ASCA101 group will receive the investigational drug twice weekly for a total of 8 doses per cycle. Participants in the placebo group will receive placebo in the same manner as the ASCA101 group.

Inclusion Criteria:
To be eligible for enrollment, subjects must meet all of the following criteria.

\*Postmenopause is defined as the permanent cessation of ovarian function, evidenced by the absence of menstruation for 12 consecutive months not attributable to other medical causes.
3. Must meet at least one of the following criteria consistent with cachexia diagnosis\*:
① Unintentional weight loss of \>5% over the past 6 months.
② BMI \<20 kg/m² with unintentional weight loss of \>2% over the past 6 months.
③ Diagnosis of sarcopenia (skeletal muscle index: \<7.26 kg/m² for men, \<5.45 kg/m² for women) with unintentional weight loss of \>2% over the past 6 months.
\*For subjects requiring confirmation of sarcopenia for cachexia diagnosis, skeletal muscle mass must be assessed using Dual-Energy X-ray Absorptiometry (DEXA).
4. Clinical laboratory results measured within 14 days prior to randomization must meet the following criteria :
* Absolute Neutrophil Count (ANC) ≥ 1,000/mm³
* Platelet count ≥ 75,000/mm³
* Hemoglobin ≥ 8.0 g/dL ④ Serum creatinine ≤ 2 × upper limit of normal (ULN) ⑤ Total bilirubin ≤ 3 × ULN ⑥ AST and ALT ≤ 3 × ULN (≤ 5 × ULN if liver metastasis is present)
* INR and aPTT ≤ 1.5 × ULN
5. Able to consume food orally.
6. Able to complete questionnaires.
7. Life expectancy of at least 16 weeks, as assessed by the investigator.
8. Eastern Cooperative Oncology Group (ECOG) performance status ≤ 3.
9. Male subjects who have not undergone vasectomy must agree to use highly effective contraception from at least 4 weeks prior to study drug administration, throughout the study period, and for 6 months following the last dose.
Highly effective contraception includes: partner's hormonal contraception, intrauterine device (IUD), intrauterine hormone-releasing system (IUS), bilateral tubal occlusion, or total sexual abstinence.
10. Able and willing to voluntarily provide written informed consent to participate in this clinical trial.
